I am trying to set up a simple Java program that creates one single animated gif from multiple other images (jpg). Can anyone give me a hook on how to achieve this in Java? I already searched Google but couldn't find anything really helpful.
Thank you guys!
Here you have an example of a class that creates an animated gif from different images:
Edit: links seems to be dead. Anyway, just to be clear, this code was done by Elliot Kroo.
Edit 2: Thanks to @Marco13
for finding the WayBack Machine link. Updated the reference!
The class provides these methods:
class GifSequenceWriter {
public GifSequenceWriter(
ImageOutputStream outputStream,
int imageType,
int timeBetweenFramesMS,
boolean loopContinuously);
public void writeToSequence(RenderedImage img);
public void close();
}
And also a little example:
public static void main(String[] args) throws Exception {
if (args.length > 1) {
// grab the output image type from the first image in the sequence
BufferedImage firstImage = ImageIO.read(new File(args[0]));
// create a new BufferedOutputStream with the last argument
ImageOutputStream output =
new FileImageOutputStream(new File(args[args.length - 1]));
// create a gif sequence with the type of the first image, 1 second
// between frames, which loops continuously
GifSequenceWriter writer =
new GifSequenceWriter(output, firstImage.getType(), 1, false);
// write out the first image to our sequence...
writer.writeToSequence(firstImage);
for(int i=1; i<args.length-1; i++) {
BufferedImage nextImage = ImageIO.read(new File(args[i]));
writer.writeToSequence(nextImage);
}
writer.close();
output.close();
} else {
System.out.println(
"Usage: java GifSequenceWriter [list of gif files] [output file]");
}
}
Props to Elliot Kroo for this code.
