Hi,

Please have the attached PDF file.

This is due to the fact that neither PXL nor PostScript supports the PDF transparency model. As a result, the content must be rendered to an image and that image placed in a relevant PXL/PS program.

There is no provision to use a display list for this, so the whole area of transparency, at the designated resolution, must fit in memory. Since Cairo PDF files routinely designate the whole page as transparent this means the whole rendered bitmap must fit in memory. You don't have enough available memory to do so, so you get a VM error (surprise!)

The default resolution of ps2write is 720 dpi, I don't know the default for PXL but I would suggest that you use the -r switch to reduce the resolution.
