Hi Yonghui,
You can use the ImageIO framework of JDK1.4 for getting the
no. of frames in the attached gif file.
Use the following code for finding the same.
import javax.imageio.*;
import javax.imageio.stream.*;
import java.util.*;
import java.io.*;
public class ImageCount {
File file = new File("a.gif");
ImageReader reader = null;
ImageInputStream iis = null;
public ImageCount() {
try{
ImageInputStream iis = ImageIO.createImageInputStream(file);
Iterator iter = ImageIO.getImageReaders(iis);
while (iter.hasNext()) {
reader = (ImageReader)iter.next();
break;
}
reader.setInput(iis, false);
int count = reader.getNumImages(true);
System.out.println(count);
}catch(Exception e){
e.printStackTrace();
}
}
public static void main(String args[]) {
ImageCount cnt = new ImageCount();
}
}
Note that animated GIF do not specify how many images are
present in the stream. Thus determining the number of images will
require the entire stream to be scanned. Hence i am passing true to
getNumImages() to indicate that the entire stream can be searched
through
for finding out the number of frames.
Please let me know if you have any problem.
Regards,
Praveen
