Hi, The code I sent is a quick example from a larger code base. In the larger code base we do a lot of image manipulation. For example, the image is loaded into memory and the pixels are analzed. This code handles 70 pages without increasing the heapsize.
So, I can increase the heapsize, but I was wondering if there is something not working well with pdfbox given we hit the heaps pace limit on the first page. Thanks.
