  • Java Simple WGS84 Lat Lon to Pixel X, Y

    - by Cnich
    I've read a multitude of information regarding map projection today. The amount of information available is overwhelming. I am attempting to simply convert lat, long values into a screen X, Y coordinate not using any map. I do not need the values projected onto any map, just on the window. The window itself is representing approx. a 1500x1500 meter location. Lat, Long accuracy needed is to a 1/10th of a second. What may be some simpler ways in converting lat/long representation to the screen? I've read several articles and post regarding translation onto images, but nothing related to the natural java coordinate system. Thanks for any insight.

  • Android ListView background colors always showing grey.

    - by fiXedd
    I have a ListView that I'm populating from a custom ListAdapter. Inside the Adapter (in the getView(int, View, ViewGroup) method) I'm setting the background color of the View using setBackgroundColor(int). The problem is that no matter what color I set the background to it always comes out a dark grey. It might also be worth noting that I'm using the Light theme. Relevant (simplified) bits of code: AndroidManifest.xml: <activity android:name=".MyActivity" android:theme="@android:style/Theme.Light" /> MyAdapter.java: @Override public View getView(int position, View convertView, ViewGroup parent) { LayoutInflater inflater = LayoutInflater.from(mContext); View av = inflater.inflate(R.layout.my_row, parent, false); av.setBackgroundColor(R.color.myRow_red); mName = (TextView) av.findViewById(R.id.myRow_name); mName.setText("This is a name"); return av; } Any ideas/suggestions?

  • Hex colors: Numeric representation for "transparent"?

    - by Pekka
    I am building a web CMS in which the user can choose colours for certain site elements. I would like to convert all colour values to hex to avoid any further formatting hassle ("rgb(x,y,z)" or named colours). I have found a good JS library for that. The only thing that I can't get into hex is "transparent". I need this when explicitly declaring an element as transparent, which in my experience can be different from not defining any value at all. Does anybody know whether this can be turned into some numeric form? Will I have to set up all processing instances to accept hex values or "transparent"? I can't think of any other way.

  • Pixel Perfect Collision Detection in HTML5 Canvas

    - by Armin Ronacher
    Hi, I want to check a collision between two Sprites in HTML5 canvas. So for the sake of the discussion, let's assume that both sprites are IMG objects and a collision means that the alpha channel is not 0. Now both of these sprites can have a rotation around the object's center but no other transformation in case this makes this any easier. Now the obvious solution I came up with would be this: calculate the transformation matrix for both figure out a rough estimation of the area where the code should test (like offset of both + calculated extra space for the rotation) for all the pixels in the intersecting rectangle, transform the coordinate and test the image at the calculated position (rounded to nearest neighbor) for the alpha channel. Then abort on first hit. The problem I see with that is that a) there are no matrix classes in JavaScript which means I have to do that in JavaScript which could be quite slow, I have to test for collisions every frame which makes this pretty expensive. Furthermore I have to replicate something I already have to do on drawing (or what canvas does for me, setting up the matrices). I wonder if I'm missing anything here and if there is an easier solution for collision detection.

  • Alternating table row colors in freemarker

    - by itsadok
    What's a good, simple way to have alternate row coloring with freemarker? Is this really the best way? <#assign row=0> <#list items as item> <#if (row % 2) == 0> <#assign bgcolor="green"> <#else> <#assign bgcolor="red"> </#if> <tr style='background-color: ${bgcolor}'><td>${item}</td></tr> <#assign row = row + 1> </#list> I tried doing this: <#assign row=0> <#list items as item> <tr style='background-color: ${(row % 2) == 0 ? "green" : "blue"}'><td>${item}</td></tr> <#assign row = row + 1> </#list> But apparently you can't user the ternary operator in there. Note: I guess I should have mentioned it earlier, but I can't use css classes or javascript, since this HTML is going into an email message.

  • Excel 2003 VBA - Method to duplicate this code that select and colors rows

    - by Justin
    so this is a fragment of a procedure that exports a dataset from access to excel Dim rs As Recordset Dim intMaxCol As Integer Dim intMaxRow As Integer Dim objxls As Excel.Application Dim objWkb As Excel.Workbook Dim objSht As Excel.Worksheet Set rs = CurrentDb.OpenRecordset("qryOutput", dbOpenSnapshot) intMaxCol = rs.Fields.Count If rs.RecordCount > 0 Then rs.MoveLast: rs.MoveFirst intMaxRow = rs.RecordCount Set objxls = New Excel.Application objxls.Visible = True With objxls Set objWkb = .Workbooks.Add Set objSht = objWkb.Worksheets(1) With objSht On Error Resume Next .Range(.Cells(1, 1), .Cells(intMaxRow, intMaxCol)).CopyFromRecordset rs .Name = conSHT_NAME .Cells.WrapText = False .Cells.EntireColumn.AutoFit .Cells.RowHeight = 17 .Cells.Select With Selection.Font .Name = "Calibri" .Size = 10 End With .Rows("1:1").Select With Selection .Insert Shift:=xlDown End With .Rows("1:1").Interior.ColorIndex = 15 .Rows("1:1").RowHeight = 30 .Rows("2:2").Select With Selection.Interior .ColorIndex = 40 .Pattern = xlSolid End With .Rows("4:4").Select With Selection.Interior .ColorIndex = 40 .Pattern = xlSolid End With .Rows("6:6").Select With Selection.Interior .ColorIndex = 40 .Pattern = xlSolid End With .Rows("1:1").Select With Selection.Borders(xlEdgeBottom) .LineStyle = xlContinuous .Weight = xlMedium .ColorIndex = xlAutomatic End With End With End With End If Set objSht = Nothing Set objWkb = Nothing Set objxls = Nothing Set rs = Nothing Set DB = Nothing End Sub see where I am looking at coloring the rows. I wanted to select and fill (with any color) every other row, kinda like some of those access reports. I can do it manually coding each and every row, but two problems: 1) its a pain 2) i don't know what the record count is before hand. How can I make the code more efficient in this respect while incorporating the recordcount to know how many rows to "loop through" EDIT: Another question I have is with the selection methods I am using in the module, is there a better excel syntax instead of these with selections.... .Cells.Select With Selection.Font .Name = "Calibri" .Size = 10 End With is the only way i figure out how to accomplish this piece, but literally every other time I run this code, it fails. It says there is no object and points to the .font ....every other time? is this because the code is poor, or that I am not closing the xls app in the code? if so how do i do that? Thanks as always!

  • producing pixel-identical images of text between Sun Java and OpenJDK

    - by yuvi
    My release script produces images of the version number to save me the trouble of manually going into the MoinMoin wiki software and changing it by hand for each release. Unfortunately, since the fonts look a little different on each platform's JVM, the result is ugly. I solved the the font inconsistency by using Lucide Sans (comes with every Java system). (Loading Fonts from TTF files was another option, but was buggy on Mac Java). The result is much better, producing the exact same image on Mac/Windows (), but a slightly different one on OpenJDK (). I believe this is caused by OpenJDK having a different font rendering system (as opposed to different fonts). Is there any way I can get all three of my target platforms (Sun Windows, Mac, OpenJDK Linux) to produce images of text that look identical?

  • No colors when using autospec

    - by kfitzpatrick
    When I'm using autospec to test a non-Rails Ruby project, I always have trouble getting my tests to show up red or green. When I run a regular 'spec spec/ --color' command I get normal red/green responses. I've tried putting all sorts of commands in the .autotest file and I can't get that to work. Also, in my Rails projects, I don't get this problem. Note: I do have the ZenTest(4.2.1) and redgreen (1.2.2) gems installed. I'm currently trying to get it working with this project: http://github.com/coreyhaines/kata-number-to-led

  • Overlay of multiple colors in ImageJ

    - by nico
    Hi everyone, I'm writing a little plugin for imageJ and I am drawing several regions as an overlay on the image. I'm using this code: ImagePlus imp = getImage(); Overlay ov = new Overlay(); for (int r=0; r<regions.length; r++) { ov.add(regions[r]); } imp.setOverlay(ov); Where regions is an array of Roi. This works as intended and draws the regions in the (hurting to my eyes) standard ImageJ cyan used for overlays. I would like to draw one particular region in another colour, but I cannot seem to find a way to do it. I found that you can change the colour of the whole overlay, but I need two colours in the same overlay. Any ideas? Thanks in advance nico

  • sorl-thumbnail unit tests fail by 1 pixel (!)

    - by stevejalim
    Hi I'm using sorl-thumbnail in a Django 1.2 (currently 1.2 RC) project and getting a surprising failure of four of sorl's built-in unit tests.

  • Highstock set different colors for different markers

    - by user1651804
    I am tryting to develop a chart in Highstock where each marker got an individual color. When i push my Data in an Array like this : series.data.push([ parseInt(Math.round(myDate.getTime())), parseInt(Math.round(myDate.getHours())) ]); The Data is shown correctly, but when i try to set the color within each data-object like this, it doesn't work to show points. series.data.push([ { x: parseInt(Math.round(myDate.getTime())), y: parseInt(Math.round(myDate.getHours())), marker:{fillColor: 'red'}} ]); What am i missing? Update: When i inspect it with firebug i can see that the series is set correctly within the chart object. so why does it now show up? :/

  • JQUERY Effect highlight, control the Start & End colors

    - by nobosh
    I have the following: $(".notifycell_email_dailydigest").effect('highlight'); The element I want to highlight is over a gray background. Problem is the highlight goes from Yellow to white, and has this ugly slow pause at the end on the white which makes the animation look horrible. How can I modify the highlighy to start with the yellow but end on the gray so it matches the background? Thanks

  • Problem exporting NSOpenGLView pixel data to some image file formats using ImageKit & CGImageDestina

    - by walkytalky
    I am developing an application to visualise some experimental data. One of its functions is to render the data in an NSOpenGLView subclass, and allow the resulting image to be exported to a file or copied to the clipboard. The view exports the data as an NSImage, generated like this: - (NSImage*) image { NSBitmapImageRep* imageRep; NSImage* image; NSSize viewSize = [self bounds].size; int width = viewSize.width; int height = viewSize.height; [self lockFocus]; [self drawRect:[self bounds]]; [self unlockFocus]; imageRep=[[[NSBitmapImageRep alloc] initWithBitmapDataPlanes:NULL pixelsWide:width pixelsHigh:height bitsPerSample:8 samplesPerPixel:4 hasAlpha:YES isPlanar:NO colorSpaceName:NSDeviceRGBColorSpace bytesPerRow:width*4 bitsPerPixel:32] autorelease]; [[self openGLContext] makeCurrentContext]; glReadPixels(0,0,width,height,GL_RGBA,GL_UNSIGNED_BYTE,[imageRep bitmapData]); image=[[[NSImage alloc] initWithSize:NSMakeSize(width,height)] autorelease]; [image addRepresentation:imageRep]; [image setFlipped:YES]; // this is deprecated in 10.6 [image lockFocusOnRepresentation:imageRep]; // this will flip the rep [image unlockFocus]; return image; } Copying uses this image very simply, like this: - (IBAction) copy:(id) sender { NSImage* img = [self image]; NSPasteboard* pb = [NSPasteboard generalPasteboard]; [pb clearContents]; NSArray* copied = [NSArray arrayWithObject:img]; [pb writeObjects:copied]; } For file writing, I use the ImageKit IKSaveOptions accessory panel to set the output file type and associated options, then use the following code to do the writing: NSImage* glImage = [glView image]; NSRect rect = [glView bounds]; rect.origin.x = rect.origin.y = 0; img = [glImage CGImageForProposedRect:&rect context:[NSGraphicsContext currentContext] hints:nil]; if (img) { NSURL* url = [NSURL fileURLWithPath: path]; CGImageDestinationRef dest = CGImageDestinationCreateWithURL((CFURLRef)url, (CFStringRef)newUTType, 1, NULL); if (dest) { CGImageDestinationAddImage(dest, img, (CFDictionaryRef)[imgSaveOptions imageProperties]); CGImageDestinationFinalize(dest); CFRelease(dest); } } (I've trimmed a bit of extraneous code here, but nothing that would affect the outcome as far as I can see. The newUTType comes from the IKSaveOptions panel.) This works fine when the file is exported as GIF, JPEG, PNG, PSD or TIFF, but exporting to PDF, BMP, TGA, ICNS and JPEG-2000 produces a red colour artefact on part of the image. Example images are below, the first exported as JPG, the second as PDF. Copy to clipboard does not exhibit this red stripe with the current implementation of image, but it did with the original implementation, which generated the imageRep using NSCalibratedRGBColorSpace rather than NSDeviceRGBColorSpace. So I'm guessing there's some issue with the colour representation in the pixels I get from OpenGL that doesn't get through the subsequent conversions properly, but I'm at a loss as to what to do about it. So, can anyone tell me (i) what is causing this, and (ii) how can I make it go away? I don't care so much about all of the formats but I'd really like at least PDF to work.

  • Blackberry pixel-specific animated focus scrolling

    - by Diego Tori
    Suppose I have a VFM full of both focusable and non-focusable fields. Since most of them are spread out far apart, the movement from one focused field to another is jerky at best, even with NullFields in between. In other words, it just sets the current y position to the next focused field without smoothly scrolling the screen. What I want to achieve is to be able to scroll at a fixed rate between fields, so it it doesn't just focus from one to another that instantaneously. After reading up on how to do this, it is a matter of overriding moveFocus and setting it via a TimerTask from an accessor method to set moveFocus, as per this link. However, I haven't seen a practical implementation of how to do this, complete with the routines that are called in the TimerTask's thread. Is there any way to achieve this type of behavior?
