Description zakiyama01 2017-08-25 08:56:02 UTC

Creating images from PDF

Certain pattern filling (TilingType = 3) was not rendered properly.


#/usr/bin/pdftocairo -r 174 -scale-to 3000 -cropbox -jpeg pdftocairo.outofmemory.pdf image


SAMPLE PDF
[pdftocairo.outofmemory.pdf](https://github.com/zakiyama01/poppler/files/1251045/pdftocairo.outofmemory.pdf)

And if you set it to a larger image size, you will get out of memory error, rendering will finish with the painting. (Sample PDF is only paint of problem so we can not confirm the stopped image)

#/usr/bin/pdftocairo -r 174 -scale-to 5000 -cropbox -jpeg pdftocairo.outofmemory.pdf image
Internal Error: cairo context error: out of memory<0a>
cairo error: out of memory
cairo error: out of memory


I tried poppler-0.57.0. The same symptoms from before.
Because I am in trouble as it is, solve out of memory? Avoidance? I am fixing it.

see patch.
