Hello! I would like to have some information about this topic. Everybody knows that it's possible to manage and even create images with PHPs gd-library, but is it possible to edit animated GIFs without losing the animation? Hope that someone is wise enough to answer this :) Martti Laine ...
In ASP.NET C# I'm trying to save a bitmap image as an 16-color non-transparent grayscale image as either a PNG or GIF. I assume I have to create a palette and then somehow attach the palette to the image but not sure how to go about doing this. The source image is a 24-bit color Bitmap. ...
I am using this peace of PHP code to save and rename some images. foreach ($phones as &$value) { $link_img = $handle = @fopen($link_img, "r"); if ($handle) { while (!feof($handle)) { $buffer .= fgets($handle, 4096); } fclose($handle); $filename = "files/nokia_".$pho...
Hello, im using the following script to convert jpgs into grayscale-images. http://bubble.ro/How_to_convert_an_image_to_grayscale_using_PHP.html i want to upgrade it to also convert pngs (with transparency) and gifs (with transparency) into grayscale images.

I need to compare 2 same-size, nearly identical images for exact differences in the RGBs of every pixel. I would like to find a tool that already does it... seems nowhere to be found on google, strangely. If I could even find a tool to print out the RGB values of every pixel I could compute it by hand (the images are small enough) or l...
Hey guys, $im = ImageCreateFromString(file_get_contents($source_file)); ImageFilter($im, IMG_FILTER_GRAYSCALE); any idea what i could do, to properly grayscale gifs and pngs with transperancy? This snippet actually works good, it transforms jpgs and pngs to grayscale. However gifs are a little bit "buggy" - they don't always work, it...

I have tried all sorts of soloutions, such as http://bloggingabout.net/blogs/rick/archive/2005/05/10/3830.aspx and http://www.codeproject.com/KB/GDI-plus/NGif.aspx but none of them seem to work correctly. NGif was okay, but the resultant gif was corrupt (white pixels on first frame). And I couldn't get Rick van den Bosch's code to work a...
Hello! I'm thinking about the best way to do two things in Java: merge two images, the background one in .PNG and the other in .GIF or .PNG (has transparency and is to overlap the first one); convert the merged image to .GIF (with transparency). I don't want to render them, just to handle the images in the java class and write the re...
Howdy! For a research project (in Java), I've got to find some way to save an animation of a graph into some file format. Now I've already got the program working fine drawing each frame. The problem is, short of learning the whole GIF or AVI file format, I have no idea how to assemble the frames programmatically into some sort of an...
Hi, Is it possible to use javascript to control which frame of a gif image is showing / stop animation. I want to be able to load a gif with several frames and only show one of them. I know I could do it with lots of seperate images, but if I can do what i want with a gif, it will only be one file to worry about. Thanks, Logan ...

When putting a favicon on your site, you can apparently use an animated gif, just by changing the gif file’s extension to .ico. http://www.k-director.com/blog/how-to-add-an-animated-faviconico/ Have you encountered any problems doing this? (Aside from users being driven mad by some stupid little blinking favicon.) Have you seen a br...

Hello. I'm using ImageMagick to convert some files from one format to another. I was always under the impression that .png files were supposed to be as big/small as .jpg if not smaller, and definitely smaller than .gif. However when I run convert photo.jpg photo.png The files I'm getting out is about 6 times bigger than the origin...
