• Why I cannot see an image if I do not use the full name of an image?

  - by Roman

  I try to add an image to JPanel. It works if I specify the full name of the image (including name of all folders). But I want my software to be machine independent (another machine does not have the same folder structure as my machine has). So, I put my image to the same place where the source is and in my code I use just name of the image (no folders' names). It does not work. I put my image into the folder where my executables are. It does not work again. So, why it does not work and what can I do with that?

• jquery background image fade

  - by Nick

  I am using jQuery to load ina background image that fills the page width / height. I have the following in the Head: $(document).ready(function() { $('body').css({ 'background-image' : 'url({HTML_BASE}images/backgrounds/randoms/{BACK_IMG})', 'background-repeat' : 'no-repeat', 'background-position' : 'center top', 'background-attachment': 'fixed', 'background-size': '100% 100%', }); $('#home-promo').innerfade({ speed: 'slow', timeout: 5000, type: 'sequence', containerheight: 'auto' }); $('.model-search').innerfade({ speed: 'slow', timeout: 5000, type: 'sequence', containerheight: '393' }); }); This works fine and can be seen at http://projects.snowshtechnologies.com/golden_dragon/home/ I want the BG image to fade in from the black background colour. I have looked at a few other threads on Stack that suggest its not possible as a body element defined in css, but in this scenario the BG image is being loaded in by jQuery. How would I go about adding a fade in to this code to bring the image in with a nice fadein?

• DMG image containing Mac OS X 10.6.5 update not recognized

  - by Lawliet

  Hello, I want to update my Mac OS X 10.6.3 and want to use the manual package update (not Software Update) and I am having this problem for two days now. First I downloaded Mac OS X 10.6.5 Combo update and on the first opening it popped up a message saying "Unable to mount: disk image not recognized". I thought that somehow the image became corrupt during the download, so I downloaded it again. Same result. And I downloaded again. And again... No use, it still states that the .dmg is not recognized. Then I tried to update my system from 10.6.3 to 10.6.4 using the same method (package installer). It worked. And of course I downloaded the 10.6.5 update (not the combo package, but the 10.6.4 10.6.5 update package)... guess what. Not recognized. I don't understand how is this possible. Did anyone has the same problem? Please don't advice me to use software update, as I need to do that on multiple Macs Thanks in advance.

• mapping rect in small image to larger image (in order to do a copyPixels operation)

  - by skinnyTOD

  Hi all - this is (I think) a relatively simple math question but I've spent a day banging my head against it and have only the dents and no solution... I'm coding in actionscript 3 - the functionality is: large image loaded at runtime. The bitmapData is stored and a smaller version is created to display on the available screen area (I may end up just scaling the large image since it is in memory anyway). The user can create a rectangle hotspot on the smaller image (the functionality will be more complex: multiple rects with transparency: example a donut shape with hole, etc) 3 When the user clicks on the hotspot, the rect of the hotspot is mapped to the larger image and a new bitmap "callout" is created, using the larger bitmap data. The reason for this is so the "callout" will be better quality than just scaling up the area of the hotspot. The image below shows where I am at so far- the blue rect is the clicked hotspot. In the upper left is the "callout" - copied from the larger image. I have the aspect ratio right but I am not mapping to the larger image correctly. Ugly code below... Sorry this post is so long - I just figured I ought to provide as much info as possible. Thanks for any tips! --trace of my data values *source BitmapDada 1152 864 scaled to rect 800 600 scaled BitmapData 800 600 selection BitmapData 58 56 scaled selection 83 80 ratio 1.44 before (x=544, y=237, w=58, h=56) (x=544, y=237, w=225.04, h=217.28) * Image here: http://i795.photobucket.com/albums/yy237/skinnyTOD/exampleST.jpg public function onExpandCallout(event:MouseEvent):void{ if (maskBitmapData.getPixel32(event.localX, event.localY) != 0){ var maskClone:BitmapData = maskBitmapData.clone(); //amount to scale callout - this will vary/can be changed by user var scale:Number =150 //scale percentage var normalizedScale :Number = scale/=100; var w:Number = maskBitmapData.width*normalizedScale; var h:Number = maskBitmapData.height*normalizedScale; var ratio:Number = (sourceBD.width /targetRect.width); //creat bmpd of the scaled size to copy source into var scaledBitmapData:BitmapData = new BitmapData(maskBitmapData.width * ratio, maskBitmapData.height * ratio, true, 0xFFFFFFFF); trace("source BitmapDada " + sourceBD.width, sourceBD.height); trace("scaled to rect " + targetRect.width, targetRect.height); trace("scaled BitmapData", bkgnImageSprite.width, bkgnImageSprite.height); trace("selection BitmapData", maskBitmapData.width, maskBitmapData.height); trace("scaled selection", scaledBitmapData.width, scaledBitmapData.height); trace("ratio", ratio); var scaledBitmap:Bitmap = new Bitmap(scaledBitmapData); var scaleW:Number = sourceBD.width / scaledBitmapData.width; var scaleH:Number = sourceBD.height / scaledBitmapData.height; var scaleMatrix:Matrix = new Matrix(); scaleMatrix.scale(ratio,ratio); var sRect:Rectangle = maskSprite.getBounds(bkgnImageSprite); var sR:Rectangle = sRect.clone(); var ss:Sprite = new Sprite(); ss.graphics.lineStyle(8, 0x0000FF); //ss.graphics.beginFill(0x000000, 1); ss.graphics.drawRect(sRect.x, sRect.y, sRect.width, sRect.height); //ss.graphics.endFill(); this.addChild(ss); trace("before " + sRect); w = uint(sRect.width * scaleW); h = uint(sRect.height * scaleH); sRect.inflate(maskBitmapData.width * ratio, maskBitmapData.height * ratio); sRect.offset(maskBitmapData.width * ratio, maskBitmapData.height * ratio); trace(sRect); scaledBitmapData.copyPixels(sourceBD, sRect, new Point()); addChild(scaledBitmap); scaledBitmap.x = offsetPt.x; scaledBitmap.y = offsetPt.y; } }

• Zooming options terminology

  - by Mark

  I've come up with 4 different ways to fit an image inside a viewing region, but I'm trouble coming up with names for them. Perhaps someone can suggest some? Fit image in viewing region, do not enlarge if image is smaller Size image so it fits snuggly inside the viewing region (enlarge if necessary) -- the image is as large as possible while still fitting within the viewing region Size image so that it fills the entire viewing region -- the image will be the same size or bigger than the viewing region 1:1 ratio; 1 pixel in the image corresponds to 1 pixel on screen All zooming options maintain aspect ratio. Stretching is just ugly, so it's not an option :)

• Which is the best image hosting site for hosting images for the website? [closed]

  Possible Duplicate: How to find web hosting that meets my requirements? I currently have a website and blog and using a limited web hosting plan.

• Tackling thin content on an images gallery

  - by Ted Wilmont

  We run an images gallery as part of our site, however we have over 8,000 images and every image has a separate HTML page of its own to display the image caption, related image and comments from users of the site. This seems to be a problem especially with the Google Panda update because these pages are technically "thin content". What would be the best way to tackle this? We'd love some feedback and advice regarding this scenario. We have a few options we thought of already but can't decide: We could noindex the separate image pages and loose any image search listings we have for the image in favour of removing these thin pages from the index. We could 301 all of the individual image pages back to the image category listing and anchor each image (e.g. #img2122) and include all of the comments and description on the category listing page itself. If we was to simply list all of the images and content on the category pages themself; what's the best method? We could add all of the content in the anchor tags and use jQuery to display them in a box when a user clicks on the image or we could use Ajax to retrieve the information. However, what's the best Ajax method for SEO? Any ideas, suggestions, tips or advice is greatly appreciated and thank you in advance for any given.

• debian (stable), google chrome, sencha and tranparency [closed]

  - by Kim Alders

  I am a bit unsure where to post this, but i guess it should be here, as it has to do with rendering in a browser. We have a sencha touch 1.1 application running in Google Chrome. On mij own computer (ubuntu) there are no problems. On the touch screen attached to a computer running debian-OS, transparency is shown as semi-transparent. It happens on sliders. Sliders have a button on them. This button is rendered bij sencha with CSS. It is NOT an image. Anyone has any idea how to get it 'nice' on debian too

• Storing images in file system and returning URLs or virtually resizing and returning byte arrays?

  - by ismaelf

  I need to create a REST web service to manage user submitted images and displaying them all in a website. There are multiple websites that are going to use this service to manage and display images. The requirements are to have 5 pre-defined image sizes available. The 2 options I see are the following: The web service will create the 5 images, store them in the file system and and store the URL's in the database when the user submits the image. When the image is requested, the web service will return an array of URLs. I see this option to be a little hard on the hard drive. The estimates are 10,000 users per site, and lets say, 100 sites. The heavy processing will be done when the user submits the image and each image is going to be pulled from the File System. The web service will store just the image that the user submits in the file system and it's URL in the database. When the user request images, the web service will get the info from the DB, load the image on memory, create its 5 instances and return an object with 5 image arrays (I will probably cache the arrays). This option is harder on the processor and memory. The heavy processing will be done when the images get requested. A plus I see for option 2 is that it will give me the option to rewrite the URL of the image and make them site dependent (prettier) than having a image repository for all websites. But this is not a big deal. What do you think of these options? Do you have any other suggestions?

• Cast Graphics to Image in C#

  - by WebDevHobo

  I have a pictureBox on a Windows Form. I do the following to load a PNG file into it. Bitmap bm = (Bitmap)Image.FromFile("Image.PNG", true); Bitmap tmp; public Form1() { InitializeComponent(); this.tmp = new Bitmap(bm.Width, bm.Height); } private void pictureBox1_Paint(object sender, PaintEventArgs e) { e.Graphics.DrawImage(this.bm, new Rectangle(0, 0, tmp.Width, tmp.Height), 0, 0, tmp.Width, tmp.Height, GraphicsUnit.Pixel); } However, I need to draw things on the image and then have the result displayed again. Drawing rectangles can only be done via the Graphics class. I'd need to draw the needed rectangles on the image, make it an instance of the Image class again and save that to this.bm I can add a button that executes this.pictureBox1.Refresh();, forcing the pictureBox to be painted again, but I can't cast Graphics to Image. Because of that, I can't save the edits to the this.bm bitmap. That's my problem, and I see no way out.

• Right way to dispose Image/Bitmap and PictureBox

  - by kornelijepetak

  I am trying to develop a Windows Mobile 6 (in WF/C#) application. There is only one form and on the form there is only a PictureBox object. On it I draw all desired controls or whatever I want. There are two things I am doing. Drawing custom shapes and loading bitmaps from .png files. The next line locks the file when loading (which is an undesired scenario): Bitmap bmp = new Bitmap("file.png"); So I am using another way to load bitmap. public static Bitmap LoadBitmap(string path) { using (Bitmap original = new Bitmap(path)) { return new Bitmap(original); } } This is I guess much slower, but I don't know any better way to load an image, while quickly releasing the file lock. Now, when drawing an image there is method that I use: public void Draw() { Bitmap bmp = new Bitmap(240,320); Graphics g = Graphics.FromImage(bmp); // draw something with Graphics here. g.Clear(Color.Black); g.DrawImage(Images.CloseIcon, 16, 48); g.DrawImage(Images.RefreshIcon, 46, 48); g.FillRectangle(new SolidBrush(Color.Black), 0, 100, 240, 103); pictureBox.Image = bmp; } This however seems to be some kind of a memory leak. And if I keep doing it for too long, the application eventually crashes. Therefor, I have X questions: 1.) What is the better way for loading bitmaps from files without locking the file? 2.) What objects needs to be manually disposed in the Draw() function (and in which order) so there's no memory leak and no ObjectDisposedException throwing? 3.) If pictureBox.Image is set to bmp, like in the last line of the code, would pictureBox.Image.Dispose() dispose only resources related to maintaining the pictureBox.Image or the underlying Bitmap set to it?

• Video-codec rater by image comparison algorithm?

  - by Andreas Hornig

  Hi, perhaps anyone knows if this is possible. comparing image quality is almost imposible to describe without subjective influences. When someone rates an image quality as good there is at least one person, that doesn't think so. human preferences are always different. So, I would like to know if there is away to "rate" the image quality by an algorithm that compares the original image to the produced one in following issues colour change(difference pixel by pixel blur rate artifacts and macroblocking the first one would be the easiest one because you could check just the diffeence in colours and can give 3 values in +- of each hex-value both last once I don't know if this is possible, but the blocking could be detected by edge-finding. and the king's quest would be to do that for more then just one image, because video is done with several frames. perhaps you expert programmers could tell me, if such an automated algo can be done to bring some objective measurement divice into rating image quality. this could perhaps calm down some h.264 is better than x264 and better than vp8 and blaaah people :) Andreas 1st posted here http://www.hdtvtotal.com/index.php?name=PNphpBB2&file=viewtopic&p=9705

• Finding text orientation in image (angle for rotation)

  - by maximus

  There is an image captured by camera, and I need to find the angle of the text in order to rotate it to make the image better for OCR results. So I know that the fourier transform can be used for that purpose, My question is, does it really gives good results or may be it is better to use something different than that? Can you tell me if there is a good method for this purpose? I am afraid that not every image containing the text will give me a good result after using fourier transform method. Actually, if I make like it is written here: link text (see the part related with an example of text image) calculating the logarithm of the magnitude of the Fourier transform of image with text and then thresholding it, I get that points and I can calculate the line approximately passing through them, and after getting the line calculate the angle, and then make an affine transform, But, what if I do not get a good result every time using this method , and make a false transform? Any ideas please to judge wether the result is correct or not, or may be another method is better? The binary image can contain noise, even if there are not so much of them, the angle found as a result can be not accurate.

• Single intent to let user take picture OR pick image from gallery in Android

  - by Damian

  I'm developing an app for Android 2.1 upwards. I want to enable my users to select a profile picture within my app (I'm not using the contacts framework). The ideal solution would be to fire an intent that enables the user to select an image from the gallery, but if an appropriate image is not available then use the camera to take a picture (or vice-versa i.e. allow user to take picture but if they know they already have a suitable image already, let them drop into the gallery and pick said image). Currently I can do one or the other but not both. If I go directly into camera mode using MediaStore.ACTION_IMAGE_CAPTURE then there is no option to drop into the gallery. If I go directly to the gallery using Intent.ACTION_PICK then I can pick an image but if I click the camera button (in top right hand corner of gallery) then a new camera intent is fired. So, any picture that is taken is not returned directly to my application. (Sure you can press the back button to drop back into the gallery and select image from there but this is an extra unnecessary step and is not at all intuitive). So is there a way to combine both or am I going to have to offer a menu to do one or the other from within my application? Seems like it would be a common use case...surely I'm missing something?

• Servlet send image from server and save in client

  - by sangi

  Hi, I'm new and just developing on J2EE. I am modifying an existing application (an OpenSource project). I need to save an image on a client sent by the server, but I do not know how. This activity must be done in a transparent manner without affecting the existing operation of the application. From the tests done I get this error: java.lang.IllegalStateException: getWriter () has Already Been Called for this response. How should carry out this task, according to your own opinion? How do I save on the client, locally, the image? Update: Thanks for the answers. My problem is that: the image is generated on the server, but not for direct client request (there is no link to click on web page), the picture is composed using other services on the Internet. reconstruct the image on the server. This image must be sent to the client to be saved locally. so I'd like it to appear a window where you assign the destination image plus I'd like the rest of the application were not affected by this activity. The application is yet on production. Thank you very much for your response.

• Problem with loading a PNG image in JApplet.

  - by Bruce

  Hi there, I'm trying to load a PNG image from JAR file when running JApplet. The file is, I think, loaded properly - there are no errors. However it is not displayed. img.png is placed in the same directory as MainClass.java file. Here is the code: InputStream imageURL = this.getClass().getResourceAsStream("img.png" ); byte[] bytes = null; try {bytes = new byte[imageURL.available()]; System.out.println(imageURL.available()); imageURL.read(bytes);} catch(Exception e) {System.out.println("bleah");} Image image = Toolkit.getDefaultToolkit().createImage(bytes); Image imageScaled = me.getScaledInstance( 100, 150, Image.SCALE_SMOOTH ); jLabel6 = new javax.swing.JLabel( new ImageIcon( imageScaled) ); and the HTML exerpt: <APPLET codebase="classes" code="myapplet/MainClass.class" archive ="LittleApplet.jar" width=700 height=500> The image, as I wrote, is probably read, but not displayed in JLabel. What am I missing/doing wrong? Thanks in advance for the reply!

• Fitting Text into an Image

  - by Abs

  Hello all, I have a function which takes in a font (ttf or otf file) and generates an image of text in different fonts. The problem I have is trying to work out how I can make the text fit in the image regardless of the font-size, type of font, and amount of text. I have tried to make the image rectangle variable so that it contains the text of different fonts without cutting a bit of the text since the image is not long or wide enough. Here is the function that I currently have, I have tried using the number of characters to determine the width of the image, but in some cases for some fonts and sizes, it still gets cut off. function generate_image($save_path, $text, $font_path){ $length = strlen($text) * 15; // Create the image $im = imagecreatetruecolor($length, 40); $white = imagecolorallocate($im, 255, 255, 255); $grey = imagecolorallocate($im, 128, 128, 128); $black = imagecolorallocate($im, 0, 0, 0); imagefilledrectangle($im, 0, 0, $length, 40, $white); $font = $font_path; imagettftext($im, 30, 0, 0, 25, $black, $font, $text); if(imagepng($im, $save_path)){ $status = true; }else{ $status = false; } imagedestroy($im); return $status; } Thank you all for any help

• Image rotate opecv error

• Dealing with image upload on server

  - by user1073320

  I have got a the following problem: I have got multi-step form where in one step user upload image to server and then few steps further supplies other information, when this information is invalid no data should be commited - also the image should be deleted. I was thinking about PHP session, but I've read here PHP - Store Images in SESSION data? that it is inefficient way. Every time you proceed step in the form the image is reloaded (in the session) and as somebody mentioned "You will want it to only be as big as it needs to be and you need to delete it as soon as you don't need it because large pieces of information in the session will slow down the session startup." - here i got a question: will it slow down the stratup the session of user who upload file or sessions of all users? I have to mention that I'm looking for solution that doesn't rely on operating system scripts (cron or etc) - I have no permission to run such scripts. The perfect solution for me would be: saving image on disk (for example in some folder named after session id) then after the latest step of form move this image or delete depending on form validation. If user unexpectedly destroy the session (for example closing the browser) of course the folder with image should be deleted. In nutshell I need somethig like callback to event "destroying session".

• Capturing image with WDS is stuck on 'Capturing Windows Image Metadata'

  - by user74499

  Hello, I'm trying to capture a rather large (100gigs) windows xp partition to a WIM file on an attached USB hard drive. Under 'Task Progress' it's saying 'Capturing Windows image Metadata', which is where it has been for a while (like 1.5 hours) - the blue bar is at the end of the screen, i.e. 100% I can move the windows around the screen so I suspect that the operation hasn't crashed yet but does this part of the process take a long time? I have only ever captured a 3gig partition before. Thanks.
