Hi, Indeed we've had problems reported in the past with certain PNGs causing out of memory errors when read with the default Java libraries: https://www.oxygenxml.com/forum/post20919.html Ideally you could identify that particular image which causes the problem and use a free image editing utility like GIMP to open and save it again. Maybe this will fix any problems it may have.

From the trace it looks like an issue with a large graphic since the code involves appears to be the PNGImageReader.
So nothing to do with the size of the chapter but to do with the size of an image.
Cheers,
E.

Good evening!
I encountered the following error while transforming a chapter of my bool:
The process 'Apache FOP' ended with code: 1.
The error was:

Specify more memory for the 'Apache FOP' as explained in the section 'Performance Problems', subsection 'External Processes' in the User Manual.
Since it is not the largest chapter and those larger ones could be transformed without any problem, I ask for any help or ideas to tackle the problem.
Regards Bernhard
