Hi Ulf,
here i am sending my code.exception is coming after printing the number of frames.
here is my code:
package gif.doc;
import com.gif4j.GifDecoder;
import com.gif4j.GifFrame;
import com.gif4j.GifImage;
import java.awt.image.IndexColorModel;
import java.io.File;
import java.io.IOException;
import java.util.Iterator;
/**
* Load a GIF Image and Extract GIF File Format Meta Info
*/
public class GifImageLoad {
// Usage:
java GifImageLoadExample [PathToGifImageToLoad] (please be sure that the gif4j jar is in your CLASSPATH)
// By default the gif4j_logotype.gif as an example gif image is used
public static void main(String[] args) {
if (args.length == 0) {
File gifImageFile = new File("D:/Myapps/read/4843a349.gif");
GifImageLoad gifImageLoadExample = new GifImageLoad();
try {
System.out.println("");
gifImageLoadExample.loadGifImageAndExtractMetaInfo(gifImageFile);
} catch (IOException e) {
e.printStackTrace();
}
} else {
GifImageLoad gifImageLoadExample = new GifImageLoad();
for (int i = 0; i < args.length; i++) {
File gifImageFile = new File(args[i]);
System.out.println("-------" + args[i] + "-------");
System.out.println("");
try {
gifImageLoadExample.loadGifImageAndExtractMetaInfo(gifImageFile);
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("");
}
}
}
public GifImage loadGifImageAndExtractMetaInfo(File file) throws IOException {
// load and decode gif image from the file
GifImage gifImage = GifDecoder.decode(file);
// print general GIF image info
System.out.println("gif image format version: " + gifImage.getVersion());
System.out.println("gif image logic screen width: " + gifImage.getScreenWidth());
System.out.println("gif image logic screen height: " + gifImage.getScreenHeight());
// check if one or more comments present
if (gifImage.getNumberOfComments() > 0) {
// get iterator over gif image textual comments
Iterator commentsIterator = gifImage.comments();
while (commentsIterator.hasNext())
System.out.println(commentsIterator.next()); // print comments
}
System.out.println("number of frames: " + gifImage.getNumberOfFrames());
int j= gifImage.getNumberOfFrames();
String s=gifImage.getComment(j);
// below we iterate frames in loop
// but it can also be done using Iterator instance: gifImage.frames()
for (int i = 0; i < gifImage.getNumberOfFrames(); i++) {
System.out.println("------frame(" + (i + 1) + ")---------");
GifFrame frame = gifImage.getFrame(i);
System.out.println("width: " + frame.getWidth());
System.out.println("height: " + frame.getHeight());
System.out.println("position: " + frame.getX() + "," + frame.getY());
System.out.println("disposal method: " + frame.getDisposalMethod());
System.out.println("delay time: " + frame.getDelay());
System.out.println("is interlaced: " + frame.isInterlaced());
}
return gifImage;
}
}
