I've got a problem with openGL on iPhone which I'm sure must have a simple solution! When I load a texture and display it, I get a lot of what I believe is called 'Colour Banding', whereby the colours, particularly on gradients, seem to get automatically 'optimized'. Just to demonstrate that this wasn't anything wrong with my own code...
I'm creating a draggable/resizable menu with all the neccesary links to control the website, a CMS-bar kind of. I'm using some png's to create the background, set with some transparency. It works great in FF, but in IE my png's get transformed after I drag my menu around: Screenshots: http://img.photobucket.com/albums/v739/Alienna/falco...
Hi folks! Here's the issue: I'm developing some Flash web sites and really enjoying AS3. The problem: PNG 24-bit images are too big... I have three PNG images with transparency that I'd like to rotate through on the "Home page" every 10 seconds or so. Great. No problem - but instead of embedding all three PNGs in the SWF, which wo...
I'm working with client's CMS and it's adding images like this and i can't change this. I tried IE7.js but it's not working <img src="~/imagefolder/CF88B05B445A4D008806C8B3E2830679.png?w=400&h=300&as=1" /> ...
I try to read an image from sdcard (in emulator) and then create a Bitmap image with the BitmapFactory.decodeByteArray method. I set the options: options.inPrefferedConfig = Bitmap.Config.ARGB_8888 options.inDither = false Then I extract the pixels into a ByteBuffer. ByteBuffer buffer = ByteBuffer.allocateDirect(width*heigh...
I looked around and decided to use a CSS approach rather than rely on JS... I figure the kind of corporate users stuck with IE6 might also have JS disabled by IT departments. So In my HTML I have: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3....
I am generating large PNG files from a Scala program. Currently, I am doing it the same way I would do it in java. I am creating a new BufferedImage and setting each pixel to the correct color. This works fine, but I am wondering if there are any good libraries for working with images in Scala? I am looking for something like Ruby's ...
Currently I'm using rsvg to load the svg (from a string, not from a file) and drawing to cairo. Anyone know a better way? I use PIL elsewhere in my application, but I don't know of a way to do this with PIL. ...
I'm trying to get my iPhone to convert some TIFs that it is downloading. They are from sources I can't control so I just have to deal with what ever gets thrown my way. I have multiple sources at the moment and only one is handled correctly. Because they are so large I am cutting them into 1024x1024 pngs and that appears to work fine wit...
(Context: running autohotkey scripts to try and automate some tests. The plan is to take screenshots and then compare them to 'standard' screenshots to detect if output has changed). Is there a 'clever' way to check if two png images are different? By clever I mean other than comparing them byte by byte? (after having compared their s...
I tried header('Content-Type: image/png'); echo base64_decode($data);` But it doesn't work. ...
All, I must have a fundamental neuron missing, but I cannot get a simple program to load a PNG file and display it in a window. I'm not sure if it is a QPixmap, a QPicture, or what. All of the samples in the QTCreator are a bit more than I need right now. Baby steps... I can get the window to display, and the program doesn't barf whe...
Is there some simple component that could display PNG 32-bit images and alpha-blend it to another image on mouse enter and on mouse leave? Or even just a simple image that can load 32-bit PNG and additionally would have Alpha parameter... I suppose I could use some skin library (alphacontrols?) or some graphics library, but for some sim...
I've got a problem with IE 8 CSS. * { margin: 0; padding: 0; } img, fieldset { border:none; } body { font-family: Arial, Helvetica, sans-serif; } In the page: <body style="background:#FFFFFF url(../public/img/s5_fa_bot_bg.png) no-repeat bottom center"> The png image is displaying correctly in Firefox and Saf...
Hi. I am relatively new to iPad programming in cocoa touch. I have a PNG with an alpha channel. I want to overlay it as a subview on a UIButton so that it looks as though the Button has a border around it. (Alpha channel is the centre of the image so the user must still see through it). I can't seem to find a way to display the alpha c...
Let's say I allow users to link to any images they like. The link would be checked for syntactical correctness, escaping etc., and then inserted in an <img src="..."/> tag. Are there any known security vulnerabilities, e.g. by someone linking to "evil.example.com/evil.jpg", and evil.jpg contains some code that will be executed due to a ...
which format of png me should use Png-8 or png-24. which one is better for website. i am confused about these. what is main different between png-8 and png-24? ...
Hi, I need in animation of sequence of more PNG files (300 png files and size is 320x480). I've try make it with 12 fps, but sometime iPhone 3g have lags... 3gs working fine. I think 2g working with lags always. I've use one UIImageView and loading images in NStimer callback by UIImage:imageWithContentOfFile. May be this is not best w...
I am generating an aspx page which then I need to convert to png and store it somewhere. A similiar situation with mine was asked before here but got still no response. I tried also the code that the Swapnil Fegade has asked but the code is looping continually making request to loading page and no conversion is actually being done. I ...
I need to replace all the white(ish) pixels in a PNG image with alpha transparency. I'm using Python in AppEngine and so do not have access to libraries like PIL, imagemagick etc. AppEngine does have an image library, but is pitched mainly at image resizing. I found the excellent little pyPNG module and managed to knock up a little fun...
