Hi,
When i try to covert pdf to image then for some pdfs i get a "out of
memory" error. So i increased heap size and then i again got the error for
some different pdf file.
for the time being assume I have no memory leak from other objects. So what
would be the reason for this memory out of error?
Would it be just that the image is so large(which is not the case i think)
that it consumes heap, or maybe pdfbox stores buffered image of each pages
in its memory and this contributes to the growing heap size?
Any insight would be wonderful.
Usually it’s because the PDF contains a compressed image which is very large
when decompressed. So the file isn’t big on disk, but it is in memory. Try using
a 32-bit JVM as these use less memory. 1GB of heap is usually enough but you
can go larger.
He does use 32bit JVM. I tried two of his files on a 64bit JVM and it
has rendered for 24 hours with -Xmx400m.
