Hi
I'd like to report an error that i found while using POI. I was retrieving
the pictures from a ppt file and saving each one in a file and it was
working ok, but i deleted one of the pictures of the PowerPoint file and POI
was still saving it in a file. Then I realized that it happens when the
source file of the picture is NOT a .PNG file. In this case, it happened
with a .BMP and a .JPG file.
Any suggestions?
Thanks,
mr_jonze.

It's how it is supposed to work. HSLFSlideShow.getPictures() returns the
actual array of images contained in the presentation.
Each image is included only once regardless of how many times you have it
in the slides.

It looks like you need the number of images shapes, not the number of
actual images contained in the ppt.
See the code:
SlideShow ppt = new SlideShow(new HSLFSlideShow("images.ppt"));
//images contained in this slide show
PictureData[] pict = ppt.getPictureData();
//get the number of image shapes
int imageCount = 0;
Slide[] slide = ppt.getSlides();
for (int i = 0; i < slide.length; i++) {
Shape[] sh = slide[i].getShapes();
for (int j = 0; j < sh.length; j++) {
if (sh[j] instanceof Picture) {
Picture p = (Picture)sh[j];
PictureData pdata = p.getPictureData();
imageCount++;
}
}
}
Since the same image can be placed on several slides imageCount may not
equal to pict.length.
