Animated GIF library for Processing Jan 3rd, 2008, 3:40pm   Recovering from a recent Newyear hangover and some requests in the forum lately motivated me to stitch together a library for importing/displaying animated GIFs    GifAnimation let's you extract animation frames into a PImage[] array or plays animations just like Movies. The hard part was done by Kevin Weiner who made this great working java GifDecoder class: http://www.java2s.com/Code/Java/2D-Graphics-GUI/GiffileEncoder.htm  So I wrapped a processing library around the decoder and added some playback controls (loop/noLoop,play,pause,stop,jump). GifAnimation supports transparent GIFs and optimized animations (the 'progressive' type) and correctly handles frame delays set in the GIF file.

Two additional things that I think would be really useful would be for the Gif object to have an "isPlaying" property and a method that returns what the current frame is. Keep up the good work!

extrapixel	Re: Animated GIF library for Processing Reply #4 - Jan 18th, 2008, 11:50pm   good idea, thank you! i put a new version online and added isPlaying(), isLooping(), currentFrame(), and some  others.

extrapixel	Re: Animated GIF library for Processing Reply #6 - Feb 15th, 2008, 12:06am   hi. i just re-checked it with the opengl-renderer on mac & win, and transparency worked as expected. can you post the code or upload the sketch somewhere (including the gif-files)?

Re: Animated GIF library for Processing Reply #7 - Feb 18th, 2008, 6:03pm   hej, this is my code, it only appears on some instances and seems to be related to 3 dimensional movement i think. import processing.opengl.*; import gifAnimation.*; PImage[] animation; Gif loopingGif; int counter; void setup() {  size(800, 600,OPENGL);  loopingGif = new Gif(this, "http://www.contact.net/maximel/diamond_lg_clr.gif");  loopingGif.loop();  background(0); } void draw() { //if (frameCount%300==0) background(0);  counter=(counter+1)%300;    for (int i=0; i<10; i++){ image(loopingGif,400,300); translate(sin(counter*.03)*100,sin(counter*.2)*200,sin(counter*.1)*10);  } }

extrapixel	Re: Animated GIF library for Processing Reply #8 - Feb 18th, 2008, 6:38pm   ok, this is a problem in processing itself and has nothing to do with the GIF library. You could load a transparent png with loadImage()... I guess exactly the same woud happen. I think it has something to do with depth sorting, don't know it exactly though.

Re: Animated GIF library for Processing Reply #10 - Sep 13th, 2008, 2:23am   Hi there Really neat library ^^ I have a question, though : where can I find the delay for each frame ? I have my PImage array, so that I can process  each frame one after another, but I'd need the delays to play it back at the right speed without losing too much "power" ^^ You can see how I use the library right here : http://melka.one.free.fr/blog/?p=131 Thanks

Re: Animated GIF library for Processing Reply #11 - Nov 24th, 2008, 7:16pm   Hello,  I am using the nonLoopingGif.  I have just made my gif longer, 20 frames in total, and it now plays very quickly. This looses the effect of the gif. Is there a reason why this gif would play so fast? I plan to add more frames to the gif also.  It plays at regular speed in other programmes. Other gifs with less frames play at correct speed.   Thanks a Million!! Aoife

extrapixel	Re: Animated GIF library for Processing Reply #12 - Nov 29th, 2008, 5:25am   hi, you can use setDelay(milliseconds) to set the time for how long the most recently added frame will be shown. also check out the docs for setDelay(). post your code if it's still not working...

kerryoco	Re: Animated GIF library for Processing Reply #13 - Jan 15th, 2009, 12:12am   I'm new, sorry if this is a stupid question - I can't get this library to work for Processing 1.0.1   ('you might be missing a library') - and it is placed in my 'libraries' folder in the sketch folder. I CAN get it to work for 0135. has it just not been updated yet? much appreciated!

PhiLho	Re: Animated GIF library for Processing Reply #14 - Jan 15th, 2009, 12:18am   Works for me... (WinXP Pro) The jar is located at <sketchbook path>\libraries\gifAnimation\library\gifAnimation.jar
