Ok. I understand. Thank you! Esteban Ruiz ________________________________ De: Tilman Hausherr <[email protected]> Enviado: martes, 3 de julio de 2018 20:25 Para: [email protected] Asunto: Re: Out Of Memory while converting a small pdf to image (pattern_issue_oom)
The patterns have XStep and YStep of 2876... so at 300dpi (which is about 4x the default) a pattern image would be created that would have a size of (2876 * 4)^2 = 132342016. If this is an ARGB image, it would take 529 368 064 bytes, i.e. 1/2 gigabyte. Detecting these is tricky... I think one would have to create a dummy tool, that doesn't create images but only calculates the size.
