I commited the first version of an image extractor for powerpoint files.
The following fragemnt of code demonstrates how to extract png images from a
ppt and save them as files:
HSLFSlideShow ppt = new HSLFSlideShow(pptfile);
Picture[] pict = ppt.getPictures();
for (int i = 0; i < pict.length; i++) {
byte[] data = pict[i].getData();
int type = pict[i].getType();
if (type == Pictures.PNG) {
FileOutputStream out = new FileOutputStream("pict_"+i+".png");
out.write(data);
out.close();
}
}
ppt.close();
Enjoy.
Best Regards, Yegor
