  • Using the contents of an array to set individual pixels in a Quartz bitmap context

    - by Magic Bullet Dave
    I have an array that contains the RGB colour values for each pixel in a 320 x 180 display. I would like to be able to set individual pixel values in the a bitmap context of the same size offscreen then display the bitmap context in a view. It appears that I have to create 1x1 rects and either put a stroke on them or a line of length 1 at the point in question. Is that correct? I'm looking for a very efficient way of getting the array data onto the graphics context as you can imagine this is going to be an image buffer that cycles at 25 frames per second and drawing in this way seems inefficient. I guess the other question is should I use OPENGL ES instead? Thoughts/best practice would be much appreciated. Regards Dave OK, have come a short way, but can't make the final hurdle and I am not sure why this isn't working: - (void) displayContentsOfArray1UsingBitmap: (CGContextRef)context { long bitmapData[WIDTH * HEIGHT]; // Build bitmap int i, j, h; for (i = 0; i < WIDTH; i++) { for (j = 0; j < HEIGHT; j++) { h = frameBuffer01[i][j]; bitmapData[i * j] = h; } } // Blit the bitmap to the context CGDataProviderRef providerRef = CGDataProviderCreateWithData(NULL, bitmapData,4 * WIDTH * HEIGHT, NULL); CGColorSpaceRef colorSpaceRef = CGColorSpaceCreateDeviceRGB(); CGImageRef imageRef = CGImageCreate(WIDTH, HEIGHT, 8, 32, WIDTH * 4, colorSpaceRef, kCGImageAlphaFirst, providerRef, NULL, YES, kCGRenderingIntentDefault); CGContextDrawImage(context, CGRectMake(0.0, HEIGHT, WIDTH, HEIGHT), imageRef); CGImageRelease(imageRef); CGColorSpaceRelease(colorSpaceRef); CGDataProviderRelease(providerRef); }

  • Android map overly transparency has unwanted gradient

    - by DavidP2190
    I'm a making my first android app and for part of it I need some shaded areas over a mapview. I've got this working so far but the when I set the alpha of the fill colour, it goes strange. I'm not allowed to post images yet, but you can see what happens here: http://i.imgur.com/leXmc.png I'm not sure what causes it, but here is some code from where it gets drawn. public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when) { Paint paint = new Paint(); paint.setStrokeWidth(2); paint.setColor(android.graphics.Color.GREEN); paint.setStyle(Paint.Style.FILL_AND_STROKE); paint.setAlpha(25); screenPoints = new Point[10]; Path path = new Path(); for (int x = 0; x<greenZone.length; x++){ screenPoints[x] = new Point(); mapView.getProjection().toPixels(greenZone[x], screenPoints[x]); } path.moveTo(screenPoints[0].x, screenPoints[0].y); for (int x = 1; x < screenPoints.length-1; x++){ paint.setAlpha(25); if (x<9){ path.lineTo(screenPoints[x].x, screenPoints[x].y); canvas.drawPath(path, paint); } else{ path.moveTo(screenPoints[screenPoints.length-1].x, screenPoints[screenPoints.length-1].y); path.lineTo(screenPoints[0].x, screenPoints[0].y); canvas.drawPath(path, paint); } } return true; } Thanks.

  • geom_ribbon doesn't work - Error in eval(expr, envir, enclos) : object 'variable' not found

    - by Marciszka
    I try to add a geom_ribbon object to my ggplot2 plot. In my data frame, I have an NA values that (I guess) may cause a problem. This is a reproducible example of data drame I have: base <- c(1:10, rep(NA, 10)) output1 <- c(rep(NA, 9), 10 - 0:10) output2 <- c(rep(NA, 9), 10 + 0:10) xaxis <- 1:20 df <- data.frame(xaxis, base, output1, output2) df xaxis base output1 output2 1 1 1 NA NA 2 2 2 NA NA 3 3 3 NA NA 4 4 4 NA NA 5 5 5 NA NA 6 6 6 NA NA 7 7 7 NA NA 8 8 8 NA NA 9 9 9 NA NA 10 10 10 10 10 11 11 NA 9 11 12 12 NA 8 12 13 13 NA 7 13 14 14 NA 6 14 15 15 NA 5 15 16 16 NA 4 16 17 17 NA 3 17 18 18 NA 2 18 19 19 NA 1 19 20 20 NA 0 20 And my attempt to plot a ggplot2 object with a geom_ribbon: dfm <- melt(df, id=1) ggplot(dfm, aes(x = xaxis, y = value, colour = variable)) + geom_line(aes(group=variable)) + geom_ribbon(data=df, aes(group = 1, ymin=output1, ymax=output2)) And, eventually, I got an error I cannot deal with: Error in eval(expr, envir, enclos) : object 'variable' not found Thank ypu in advance for any suggestions.

  • Fullcalendar doesn't render color when using eventRender

    - by jaffa
    When I set-up fullCalendar and set eventRender function callback, I want to set the color of the event depending if LeadId is null or not. But this doesn't seem to work even though the documentation says so: http://arshaw.com/fullcalendar/docs/event_data/Event_Object/#color-options Is there any way to set the event color to change based on the data? calendar = $('#dayview').fullCalendar({ .... timeFormat: 'HH:mm', columnFormat: { agendaDay: 'dddd dd/MM/yyyy' }, eventClick: function (calEvent, jsEvent, view) { var leadUrl = "/Leads/" + calEvent.LeadId; window.location = leadUrl; }, eventRender: function (event, element) { if (event.LeadId != null) { event.eventColor = "#B22222"; event.eventBackColor = "#B22222"; } }, UPDATE: This is really strange. The event has all my properties returned for the event off the server. element is just the DOM element for the event. When I drag/move the event to somewhere else in the calendar, the event turns red, and if I inspect the event object it now has color set to Red. So the question is why isn't it applying on the 1st render, but on subsequent renders (i.e. after move) the colour gets applied?

  • Jquery to hightlight elements in a list

    - by John
    Hi I have a ol list: <ol> <li class="group1">item 1</li> <li class="group1">item 2</li> <li class="group2"> item 3</li> <li class="group3">item 4</li> <li class="group1">item 5</li> <li class="group3"> item 6</li> <ol> and a set of checkboxes which correspond to the class names <input type="checkbox" value="group1" />group 1 <input type="checkbox" value="group2" />group 2 <input type="checkbox" value="group3" />group 3 What I want to happen is that when a user clicks on a checkbox to 'tick' it, any li rows which are not checked are fadedOut (change opacity) and then any rows which have the class which matches the value of the checkbox are highlighter (background colour changed to yellow). So for example if group 3 was clicked, item 4 and item 6 would be highlighted. Then if group 2 was clicked item 3 would be highlighted (item 4 and 6 would remain highlighted). If group 2 was un-ticked, item 3 would become faded out although item 4 and 6 would remain highlighted. The code I have at the moment is: $('input').click(function(){ input = $(this); classVal = "." + input.val(); elements = $(classVal ); if (input.is(':checked')) { elements.css("background-color", "#FFFF00"); } else { elements.css("background-color", ""); } }); This handles the highlighting but does not do the fading of the unchecked elements. I know I can change the opacity using css("opacity", 0.33) or fadeTo("slow", 0.33) but not sure how to handle this in the code and where to put it. If any of my other code can be tidied up also please let me know Thanks

  • Most "thorough" distribution of points around a circle

    - by hippietrail
    This question is intended to both abstract and focus one approach to my problem expressed at "Find the most colourful image in a collection of images". Imagine we have a set of circles, each has a number of points around its circumference. We want to find a metric that gives a higher rating to a circle with points distributed evenly around the circle. Circles with some points scattered through the full 360° are better but circles with far greater numbers of points in one area compared to a smaller number in another area are less good. The number of points is not limited. Two or more points may coincide. Coincidental points are still relevant. A circle with one point at 0° and one point at 180° is better than a circle with 100 points at 0° and 1000 points at 180°. A circle with one point every degree around the circle is very good. A circle with a point every half degree around the circle is better. In my other (colour based question) it was suggested that standard deviation would be useful but with caveat. Is this a good suggestion and does it cope with the closeness of 359° to 1°?

  • Scientific Algorithms that can produce imagery, pseudocode perhaps?

    - by Ross
    Hello, I have a client who are based in the field of mathematics. We are developing, amongst other things, a website. I like to create a mock-up of a drawing tool that an produce some imagery in the background based on some scientific algorithms. The intention being that the may client, later, may create there own. (They use emacs for everything, great client.) I'm look for an answer of where or what to go looking for. Not code specific, pseudocode even, as we can adapt and have not yet settled on a platform. I'm afraid my mathematic stops at the power of two and some trigonometry. Appreciated if they're are any mathematics related students/academics how could enlighten me? What to search for will be accepted? Edit: To summarise/clarify, I want to draw pretty pictures (the design perspective). I want them to have some context (i.e. not just for the sake of pretty images but have some explanation available). In essence I would to create a rendering engine which we can draw the images and we set the style parameters: line, colour, etc... But to pursue this option I want to experiment myself. Thanks Ross

  • Make an empty DIV height and width of its container

    - by Olly F
    My HTML currently contains a background image that stretches with the viewport. Within that, I plan to place a div that stretches to the height and width of the viewport and has black background colour at 50% opacity. I've set the div to be 100% width and height. The div is not stretching and I can't figure out why! HTML: <!DOCTYPE HTML> <html lang="en"> <head> <title>Tester</title> <meta charset="UTF-8"/> <style type="text/css"> html { background: url(http://cjpstudio.com/wp-content/uploads/2011/12/cityrock1.jpg) no-repeat center center fixed; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; background-size: cover; } #background-color { width: 100%; height: 100%; background-color: #000000; } </style> </head> <body> <div id="background-color"> </div> </body>

  • Inline text box labels with WPF

    - by Douglas
    I'm trying to reproduce the layout of some paper forms in a WPF application. Labels for text boxes are to be "inline" with the content of the text boxes, rather than "outside" like normal Windows forms. So, with an Xxxxxx label: +-----------------------------+ | Xxxxxx: some text written | | in the multiline input. | | | | another paragraph continues | | without indentation. | | | | | +-----------------------------+ The Xxxxxx cannot be editable, if the user selects all the content of the text box, the label must remain unselected, I need to be able to style the text colour/formatting of the label separately, when there is no text in the text box, but it has focus, the caret should flash just after the label, and I need the baselines of the text in the text box and the label to line up. One solution I tried was putting a textblock partially over the input, then using text indent to indent the editable text, though this caused problems with following paragraphs, since they were indented too. I'm not sure how to indent just the first paragraph. It required some fiddling to get the text to line up - a more reliable setup would be ideal. So, any suggestions on how to set this up? Thanks

  • Auto scale and rotate images

    - by Dave Jarvis
    Given: two images of the same subject matter; the images have the same resolution, colour depth, and file format; the images differ in size and rotation; and two lists of (x, y) co-ordinates that correlate the images. I would like to know: How do you transform the larger image so that it visually aligns to the second image? (Optional.) What are the minimum number of points needed to get an accurate transformation? (Optional.) How far apart do the points need to be to get an accurate transformation? The transformation would need to rotate, scale, and possibly shear the larger image. Essentially, I want to create (or find) a program that does the following: Input two images (e.g., TIFFs). Click several anchor points on the small image. Click the several corresponding anchor points on the large image. Transform the large image such that it maps to the small image by aligning the anchor points. This would help align pictures of the same stellar object. (For example, a hand-drawn picture from 1855 mapped to a photograph taken by Hubble in 2000.) Many thanks in advance for any algorithms (preferably Java or similar pseudo-code), ideas or links to related open-source software packages.

  • OpenGL 3.3 different colours with fragment shader [solved]

    - by Andrew Seymour
    I'm an OpenGL newbie. I'm trying to colour 3 circles but only 3 white circles are appearing. n is 3 in this example. Each vertice has 5 points, 2 for position and 3 for color Here is where I think a problem may lie: glEnableVertexAttribArray(0); glBindBuffer(GL_ARRAY_BUFFER, vertexbuffer); glVertexAttribPointer( 0, 2, GL_FLOAT, GL_FALSE, 5*sizeof(float), (void*)0 ); glEnableVertexAttribArray(1); glVertexAttribPointer( 1, 3, GL_FLOAT, GL_FALSE, 5*sizeof(float), (void*)(2*sizeof(float)) ); glDrawElements(GL_TRIANGLES, 20 * 3 * n, GL_UNSIGNED_INT, 0); glDisableVertexAttribArray(0); glDisableVertexAttribArray(1); My shaders: #version 330 core in vec3 Color; out vec4 outColor; void main() { outColor = vec4(Color, 1.0); } #version 330 core layout(location = 0) in vec2 position; layout(location = 1) in vec3 color out vec3 Color void main(){ gl_Position = vec4(position, 0.0, 1.0); Color = color; } Thanks for taking a look Andy EDIT: layout(location = 1) in vec3 color out vec3 Color layout(location = 1) in vec3 color; out vec3 Color;

  • Understanding REST through an example

    - by grifaton
    My only real exposure to the ideas of REST has been through Ruby on Rails' RESTful routing. This has suited me well for the kind of CRUD-based applications I have built with Rails, but consequently my understanding of RESTfulness is somewhat limited. Let's say we have a finite collection of Items, each of which has a unique ID, and a number of properties, such as colour, shape, and size (which might be undefined for some Items). Items can be used by a client for a period of time, but each Item can only be used by one client at once. Access to Items is regulated by a server. Clients can request the temporary use of certain items from a server. Usually, clients will only be interested in getting access to a number of Items with particular properties, rather than getting access to specific Items. When a client requests use of a number of Items, the server responds with a list of IDs corresponding to the request, or with a response that says that the requested Items are not currently available or do not exist. A client can make the following kinds of request: Tell me how many green triangle Items there are (in total/available). Give me use of 200 large red Items. I have finished with Items 21, 23, 23. Add 100 new red square Items. Delete 50 small green Items. Modify all big yellow pentagon Items to be blue. The toy example above is like a resource allocation problem I have had to deal with recently. How should I go about thinking about it RESTfully?

  • How to merge two icons together? (overlay one icon on top of another)

    - by demoncodemonkey
    I've got two 16x16 RGB/A .ICO icon files, each loaded into a separate System.Drawing.Icon object. How would you create a new Icon object containing the merge of the two icons (one overlaid on top of the other)? Edit: I probably wasn't too clear, I don't want to blend two images into each other, I want to overlay one icon on top of another. I should add that the icons already contain transparent parts and I do not need any transparent "blending" to make both icons visible. What I need is to overlay the non-transparent pixels of one icon over the top of another icon. The transparent pixels should let the background icon show through. For example, look at the stackoverflow icon. It has some areas that are grey and orange, and some areas that are totally transparent. Imagine you want to overlay the SO icon on top of the Firefox icon. You would see the greys and oranges of the SO icon in full colour, and where the SO icon is transparent, you would see those parts of the Firefox icon.

  • PNG Textures not loading on HTC desire

    - by Matthew Tatum
    Hi I'm developing a game for android using OpenGL es and have hit a problem: My game loads fine in the emulator (windows xp and vista from eclipse), it also loads fine on a T-Mobile G2 (HTC Hero) however when I load it on my new HTC Desire none of the textures appear to load correctly (or at all). I'm suspecting the BitmapFactory.decode method although I have no evidence that that is the problem. All of my textures are power of 2 and JPG textures seem to load (although they don't look great quality) but anything that is GIF or PNG just doesn't load at all except for a 2x2 red square which loads fine and one texture that maps to a 3d object but seems to fill each triangle of the mesh with the nearest colour). This is my code for loading images: AssetManager am = androidContext.getAssets(); BufferedInputStream is = null; try { is = new BufferedInputStream(am.open(fileName)); Bitmap bitmap; bitmap = BitmapFactory.decodeStream(is); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0); bitmap.recycle(); } catch(IOException e) { Logger.global.log(Level.SEVERE, e.getLocalizedMessage()); } finally { try { is.close(); } catch(Exception e) { // Ignore. } } thanks

  • .tpl files and website problem

    - by whitstone86
    Apologies if the title is in lowercase but it's describing an extension format. I've started using Dwoo as my template engine for PHP, and am not sure how to convert my PHP files into .tpl templates. My site is similar to, but not the same as, http://library.digiguide.com/lib/programme/Medium-319648/Drama/ with its design (except colour scheme and site name are different, plus it's in PHP - so copyright issues are avoided here, the design arguably could be seen as parody even though the content is different. The database is called tvguide, and it has these tables: Programmes House M.D. Medium Police Stop! American Dad! The tablenames of the above programmes are: housemdonair mediumonair policestopair americandad1 Episodes The tablenames for the above programmes' episode guides are: housemdepidata mediumepidata policestopepidata americandad1epidata All of them have the following rows: id (not an auto-increment, since I wish to dynamically generate a page from this) episodename seriesnumber episodenumber episodesynopsis (the above four after id do exactly as stated) I have a pagination script that works, it displays 20 records per page as I want it to. This is called pmcPagination.php - but I won't post it in full since it would take up too much space. However, I'm trying to get it so that variables are filled in like this: (ok, so the examples below are ASP.NET, but if there's a PHP/MySQL equivalent I would gratefully appreciate this!!): http://library.digiguide.com/lib/episode/741168 http://library.digiguide.com/lib/episode/714829 with the episode detail and data. My site works, but it's fairly basic, and it's not online yet until my bugs are fixed. Mod_rewrite is enabled so my site reads as http://mytvguide.com/episode/123456 or http://mytvguide.com/programme/123456 http://mytvguide.com/WorldInAction/123456/Documentary/ I've tried looking on Google, but am not sure how to get this TV guide script to work at its best - but I think .tpl, and .php/MySQL is the way to go. Any advice anyone has on making this project into a fully workable, ready to use site would be much appreciated, I've spent months refining this project! P.S. Apologies for the length of this, hope it describes my project well.

  • Polling a web URL until event

    - by Jaxo
    I'm really sorry about the crappy title - if anybody has a better way of wording it, please edit it! I basically need to have a C# application run a function if the output of a URL is a certain value. For example, if the website says blue the background colour will be blue, red to make it red, etc. The problem is I don't want to spam my webserver with checks. The 4 bytes it downloads each time is negligible, but if I were to deploy this type of system on multiple computers, it would get slower and slower and the bandwidth would add up quickly. So my question is: How can my desktop application run a piece of code only when a web URL has a different output without checking each time? I can't use sockets, and any sort of LAN protocol won't end up working. My reasoning behind this potentially nefarious code is to be able to mute computers by updating a file on the website (as you may have seen in my previous question today, sorry!). I'd like it to be rather quick, and not have the refresh time minutes apart, a few seconds at the most would be ideal. How can I accomplish this? The website's code is easy, but getting the C# application to check when it changes is the part I'm stuck on. Nothing shows up on the website other than the command. Thanks!

  • Color banding only on Android 4.0+

    - by threeshinyapples
    On emulators running Android 4.0 or 4.0.3, I am seeing horrible colour banding which I can't seem to get rid of. On every other Android version I have tested, gradients look smooth. I have a SurfaceView which is configured as RGBX_8888, and the banding is not present in the rendered canvas. If I manually dither the image by overlaying a noise pattern at the end of rendering I can make the gradients smooth again, though obviously at a cost to performance which I'd rather avoid. So the banding is being introduced later. I can only assume that, on 4.0+, my SurfaceView is being quantized to a lower bit-depth at some point between it being drawn and being displayed, and I can see from a screen capture that gradients are stepping 8 values at a time in each channel, suggesting a quantization to 555 (not 565). I added the following to my Activity onCreate function, but it made no difference. getWindow().setFormat(PixelFormat.RGBA_8888); getWindow().addFlags(WindowManager.LayoutParams.FLAG_DITHER); I also tried putting the above in onAttachedToWindow() instead, but there was still no change. (I believe that RGBA_8888 is the default window format anyway for 2.2 and above, so it's little surprise that explicitly setting that format has no effect on 4.0+.) Which leaves the question, if the source is 8888 and the destination is 8888, what is introducing the quantization/banding and why does it only appear on 4.0+? Very puzzling. I wonder if anyone can shed some light?

  • Increase content size of UIWebView using Javascript

    - by Sam
    Hi folks, I have a translucent toolbar over the bottom of my UIWebView. The trouble is, if there is a link at the bottom of the page, I can't press it because the webview will always bounce back down to the bottom. I don't want to shrink the webview and use a solid colour toolbar, and UIWebViews interface doesn't open much up. What I would like to do, ideally, is to actually increase the size of the web page by one toolbar height, so that I can scroll that extra bit and have all the content above the toolbar, but when scrolling down I will be able to see the page content through the toolbar. I could use the stringByEvaluatingJavaScriptFromString: function of UIWebView. I'm very rusty on JavaScript- is it possible for me to do this? Increase the window height or something? I tried: [webView stringByEvaluatingJavaScriptFromString: [NSString stringWithFormat:@"window.resizeBy(0,%d);", TOOLBAR_HEIGHT] ]; but it didn't do anything. Any pointers welcome. Thanks.

  • Crystal Reports Cross Tab Conditional Formatting

    - by ltran
    I would like to achieve a simplified result similar to the "Color Scale" function in Excel i.e. gradient colouring based on the lowest value (red) to highest value (green), except in my cross tab using Crystal Reports 2008. My cross tab looks a little like this: HOURS L1 L2 L3 L4 Total 1 hours | 5 | 0 | 1 | 16 | 22 | 2 hours | 0 | 1 | 0 | 10 | 11 | 3 hours | 8 | 2 | 6 | 12 | 28 | TOTAL |13 | 3 | 7 | 38 | 61 | The principle of my function is find the maximum value in the cross table then use 20%, 40%, 60%, 80% values to colour the background. Function is as follows (in the format background section): if currentfieldvalue < ((Maximum (MakeArray (CurrentColumnIndex, CurrentRowIndex, 1)))*0.2) then color(255,0,0) else if (currentfieldvalue >= ((Maximum (MakeArray (CurrentColumnIndex, CurrentRowIndex, 1)))*0.2) and currentfieldvalue < ((Maximum (MakeArray (CurrentColumnIndex, CurrentRowIndex, 1)))*0.4)) then color(255,192,0) else if (currentfieldvalue >= ((Maximum (MakeArray (CurrentColumnIndex, CurrentRowIndex, 1)))*0.4) and currentfieldvalue < ((Maximum (MakeArray (CurrentColumnIndex, CurrentRowIndex, 1)))*0.6)) then color(255,255,0) else if (currentfieldvalue >= ((Maximum (MakeArray (CurrentColumnIndex, CurrentRowIndex, 1)))*0.6) and currentfieldvalue < ((Maximum (MakeArray (CurrentColumnIndex, CurrentRowIndex, 1)))*0.8)) then color(146,208,80) else if (currentfieldvalue >= ((Maximum (MakeArray (CurrentColumnIndex, CurrentRowIndex, 1)))*0.8)) then color(0,176,80) It's not elegant, nor does it work properly, any assistance/suggestions would be much appreciated. I wasn't expecting it to be so complicated as originally I was working with the below assuming it would work, except it tells me that "CurrentFieldValue" is not a field. if CurrentFieldValue < ((Maximum (CurrentFieldValue))*0.2) then color(255,0,0) else if ... etc.

  • Updating the foreground of a label on window active property-WPF

    I have a label which shows the name of the window. I want to update the colour of the label on the IsActive property of the window using styles and triggers so that all the labels inheriting this style should exhibit the same property. Please can anyone suggest me how? I tried like this: <Style TargetType="{x:Type Label}" x:Key="HeaderLabel"> <Style.Triggers> <DataTrigger Binding="{Binding (Window.IsActive)}" Value="True"> <Setter Property="FontSize" Value="15"/> <Setter Property="FontWeight" Value="Bold"/> <Setter Property="FontFamily" Value="Arial"/> <Setter Property="Foreground" Value="Black"/> <Setter Property="HorizontalAlignment" Value="Left"/> </DataTrigger> <DataTrigger Binding="{Binding (Window.IsActive)}" Value="False"> <Setter Property="FontSize" Value="15"/> <Setter Property="FontWeight" Value="Bold"/> <Setter Property="FontFamily" Value="Arial"/> <Setter Property="Foreground" Value="White"/> <Setter Property="HorizontalAlignment" Value="Left"/> </DataTrigger> </Style.Triggers> </Style>

  • Highlighting Changes in Java

    - by Buzz Lightyear
    Basically, i have done my program so that it will display differences in strings and display the whole line. I want to highlight (in a colour) the differences in the line. Example: Original at line 5 <rect x="60.01" width="855.38" id="rect_1" y="-244.35" height="641.13" style="stroke-width: 1; stroke: rgb(0, 0, 0); fill: none; "/> Edited at line 5 <rect x="298.43" width="340.00" y="131.12" height="380.00" id="rect_1" style="stroke-width: 1; stroke: rgb(0, 0, 0); fill: rgb(255, 102, 0); "/> In this example, the width is different from the 'original' from the 'edited' version. I would like to be able to highlight that difference and any other difference. My code so far: Patch patch = DiffUtils.diff(centralFile, remoteFile); StringBuffer resultsBuff = new StringBuffer(remoteFileData.length); for (Delta delta : patch.getDeltas()) { resultsBuff.append("Original at line " + delta.getOriginal().getPosition() + "\n"); for (Object line : delta.getOriginal().getLines()) { resultsBuff.append(" " + line + "\n"); } resultsBuff.append("Edited at line " + delta.getRevised().getPosition() + "\n"); for (Object line : delta.getRevised().getLines()) { resultsBuff.append(" " + line + "\n"); } resultsBuff.append("\n"); } return resultsBuff.toString(); } That will display two whole lines like the example before (the original and the edited version) I want to be able to highlight the changes that have actually been made, is there any way to do this in Java?

    Hello, Cant really find any useful information on this through Google so hope someone here with some knowledge can help. I have a set of results which are pulled from a multi dimensional array. Currently the array key is the price of a product whilst the item contains another array which contains all the product details. key=>Item(name=>test, foo=>bar) So currently when I list the items I just order by the key, smallest first and it lists the products smallest price first. However I want to build on this so that when a user sees the results they can choose other ordering options like list all products by a name, certain manufacturer, colour, x ,y ,z etc etc from a drop down box(or something similar) This is where I need some guidance. Im just not sure how to go about it or best practise or anything. The only way I can think of is to order all the items by the nested array eg by the name, manufacturer etc. but how do I do that in PHP? Hope you understand what im trying to achieve(if not just ask). Any help on this with ideas, approaches or examples would be great. Thanks for reading p.s Im using PHP5

  • Using Color.rgb() doesnt work for full 0...255 range

    - by superflyninja
    I'm writing an android game using opengl. I'm using: colour = Color.rgb(theR,theG,theB); (all ints) to store the color of a rectangle. Then I parse out the RGB to render the rectangle: colorR = Color.red(color); colorG = Color.green(color); colorB = Color.blue(color); For example for color 53,130,255 this should result in a blue but on my app it results in a white. If i use 1,1,1 i get white. If i use 0,0,0 i get black. If i use 0,1,0 I get green etc. So it looks like any value over one is treated as 1 and so i am not getting the full 0...255 range. I tried using Color.argb and color = Color.parseColor(theColor) where the Color is a string. I'm using this in an opengles app. I have a class to display a rectangle of color. This definitely works fine as the correct size rectangle is rendered, just not a color using values above 1. I also use textures and everything displays fine. any ideas? thanks a million

  • Launch 7:Windows Phone 7 Style Live Tiles On Android Mobiles

    - by Gopinath
    Android is a great mobile OS but one thought that lingers in the mind of few Android owners is: Am I using a cheap iPhone? This is valid thought for many low end Android users as their phones runs sluggish and the user interface of Android looks like an imitation of iOS. When it comes to Windows Phone 7 users, even though their operating system features are not as great as iPhone/Android but it has its unique user interface; Windows Phone 7 user interface is a very intuitive and fresh, it’s constantly updating Live Tiles show all the required information on the home screen. Android has best mobile operating system features except UI and Windows Phone 7 has excellent user interface. How about porting Windows Phone 7 Tiles interface on an Android? That should be great. Launch 7 app brings the best of Windows Phone 7 look and feel to Android OS. Once the Launcher 7 app is installed and activated, it brings Live Tiles or constantly updating controls that show information on Android home screen. Apart from simple and smooth tiles, there are handful of customization options provided. Users can change colour of the tiles, add new tiles, enable/disable transitions. The reviews on Android Market are on the positive side with 4.4 stars by 10,000 + reviewers. Here are few user reviews 1. Does what it says. only issue for me is that the app drawer doesn’t rotate. And I would like the UI to rotate when my KB is opened. HTC desire z – Jonathan 2. Works great on atrix.Kudos to developers. Awesome. Though needs: Better notification bar More stock images of tiles Better fitting of widgets on tiles – Manny 3. Looks really good like it much more than I thought I would runs real smooth running royal ginger 2.1 – Jay 4. Omg amazing i am definetly keeping it as my default best of android and windows – Devon 5. Man! An update every week! Very very responsive developer! – Andrew You can read more reviews on Android Market here.  There is no doubt that this application is receiving rave reviews. After scanning a while through the reviews, few complaints throw light on the negative side: Battery drains a bit faster & Low end mobile run a bit sluggish. The application is available in two versions – an ad supported free version and $1.41 ad free version.

  • how can I specify interleaved vertex attributes and vertex indices

    - by freefallr
    I'm writing a generic ShaderProgram class that compiles a set of Shader objects, passes args to the shader (like vertex position, vertex normal, tex coords etc), then links the shader components into a shader program, for use with glDrawArrays. My vertex data already exists in a VertexBufferObject that uses the following data structure to create a vertex buffer: class CustomVertex { public: float m_Position[3]; // x, y, z // offset 0, size = 3*sizeof(float) float m_TexCoords[2]; // u, v // offset 3*sizeof(float), size = 2*sizeof(float) float m_Normal[3]; // nx, ny, nz; float colour[4]; // r, g, b, a float padding[20]; // padded for performance }; I've already written a working VertexBufferObject class that creates a vertex buffer object from an array of CustomVertex objects. This array is said to be interleaved. It renders successfully with the following code: void VertexBufferObject::Draw() { if( ! m_bInitialized ) return; glBindBuffer( GL_ARRAY_BUFFER, m_nVboId ); glBindBuffer( GL_ELEMENT_ARRAY_BUFFER, m_nVboIdIndex ); glEnableClientState( GL_VERTEX_ARRAY ); glEnableClientState( GL_TEXTURE_COORD_ARRAY ); glEnableClientState( GL_NORMAL_ARRAY ); glEnableClientState( GL_COLOR_ARRAY ); glVertexPointer( 3, GL_FLOAT, sizeof(CustomVertex), ((char*)NULL + 0) ); glTexCoordPointer(3, GL_FLOAT, sizeof(CustomVertex), ((char*)NULL + 12)); glNormalPointer(GL_FLOAT, sizeof(CustomVertex), ((char*)NULL + 20)); glColorPointer(3, GL_FLOAT, sizeof(CustomVertex), ((char*)NULL + 32)); glDrawElements( GL_TRIANGLES, m_nNumIndices, GL_UNSIGNED_INT, ((char*)NULL + 0) ); glDisableClientState( GL_VERTEX_ARRAY ); glDisableClientState( GL_TEXTURE_COORD_ARRAY ); glDisableClientState( GL_NORMAL_ARRAY ); glDisableClientState( GL_COLOR_ARRAY ); glBindBuffer( GL_ARRAY_BUFFER, 0 ); glBindBuffer( GL_ELEMENT_ARRAY_BUFFER, 0 ); } Back to the Vertex Array Object though. My code for creating the Vertex Array object is as follows. This is performed before the ShaderProgram runtime linking stage, and no glErrors are reported after its steps. // Specify the shader arg locations (e.g. their order in the shader code) for( int n = 0; n < vShaderArgs.size(); n ++) glBindAttribLocation( m_nProgramId, n, vShaderArgs[n].sFieldName.c_str() ); // Create and bind to a vertex array object, which stores the relationship between // the buffer and the input attributes glGenVertexArrays( 1, &m_nVaoHandle ); glBindVertexArray( m_nVaoHandle ); // Enable the vertex attribute array (we're using interleaved array, since its faster) glBindBuffer( GL_ARRAY_BUFFER, vShaderArgs[0].nVboId ); glBindBuffer( GL_ELEMENT_ARRAY_BUFFER, vShaderArgs[0].nVboIndexId ); // vertex data for( int n = 0; n < vShaderArgs.size(); n ++ ) { glEnableVertexAttribArray(n); glVertexAttribPointer( n, vShaderArgs[n].nFieldSize, GL_FLOAT, GL_FALSE, vShaderArgs[n].nStride, (GLubyte *) NULL + vShaderArgs[n].nFieldOffset ); AppLog::Ref().OutputGlErrors(); } This doesn't render correctly at all. I get a pattern of white specks onscreen, in the shape of the terrain rectangle, but there are no regular lines etc. Here's the code I use for rendering: void ShaderProgram::Draw() { using namespace AntiMatter; if( ! m_nShaderProgramId || ! m_nVaoHandle ) { AppLog::Ref().LogMsg("ShaderProgram::Draw() Couldn't draw object, as initialization of ShaderProgram is incomplete"); return; } glUseProgram( m_nShaderProgramId ); glBindVertexArray( m_nVaoHandle ); glDrawArrays( GL_TRIANGLES, 0, m_nNumTris ); glBindVertexArray(0); glUseProgram(0); } Can anyone see errors or omissions in either the VAO creation code or rendering code? thanks!
