Hey, I have a PDF File with 281 pages, each page is basically just one big image. When I load it with PDFBox, my aim is to compress the images to make them smaller. My approach is loading the Document, iterating over every page, checking for all resources on it if they are of type PDImageXObject. Then i do some compression.
The crazy thing is, my file somehow has on every page a resource to every resource. Seems, that all the images are somehow shared... So my program now does 281 * 281 compressions which is really slow. Im not sure whats the best way to detect shared resources, is there some easy way? Also if you see other approaches serving the same purposes of compressing large images, i would be interested...
