java.lang.OutOfMemoryError: Java heap space from SimpleRenderer #65
Description
Trying to evaluate ghost4j but am getting an outofmemory error on ghost4j 1.0.1
My env:
64 bit linux (arch)
Java 1.8.0_131
Tried multiple times to attach pdf to this ticket.. github kept giving me errors so created a repo with support files
- Driver.java (test app)
- Pro-Git.pdf (test pdf, 7.7M)
https://github.com/daynok/ghost4j-outofmemory
Ran pdfinfo on the pdf and as far as I can tell it looks good. Also opened the pdf in firefox without issue.
From what I can tell the outofmemory error gets thrown at
renderer.render(document);
I'm not sure if I'm doing something wrong programmatically or what.
End goal, convert pdf pages to png's.
