XeTeX pstricks larger page size is cropped to A4

Question

In a Plain-XeTeX document, if I set the page size to anything bigger than the default page size, (A4 in my case) then all the pstricks elements beyond the size of an A4 page are trimmed of, so only a portion of the image is seen on the page. I've tried to set the page size before and after \input pstricks, tried put it in pspicture, put it outside of it, set the pspicture size to (0, 0), (10, 10), used \pspicture* instead, nothing could get rid of that cropping region, and draw beyond that. I also tried to use pdf special commands in vain.

The final TeX file I'm trying with is the following:

%\special{papersize=500mm,500mm}
\special{pdf:pagesize width 500mm height 500mm}
\hsize=500mm\vsize=500mm
\input pstricks

%\pspicture(0,0)
\psline(-500cm,0)(1mm,0)
\psline(0,100cm)(0,-500cm)
%\endpspicture

Somewhere, over the rainbow.

I've tried this in the latest of these systems, and none of them worked: MiKTeX 2.9 (64-bit), MacTeX (2013 is the version number I believe?)

The following output can be seen whatever I tried. The vertical line only starts from somewhere about the middle of the page where it should start from above the text, and horizontal line isn't visible at all.

How can I resolve this issue?

Answer 1

XeTeX writes the PostScript code of pstricks in a temporary PostScript file and runs the result through the command, that is configured in entry D of TDS:dvipdfmx/dvipdfmx.cfg, e.g. (TL2013):

D  "rungs -q -dNOPAUSE -dBATCH -dEPSCrop -sDEVICE=pdfwrite -dCompatibilityLevel=%v -dAutoFilterGrayImages=false -dGrayImageFilter=/FlateEncode -dAutoFilterColorImages=false -dColorImageFilter=/FlateEncode -sOutputFile='%o' '%i' -c quit"

Because of -dEPSCrop it works fine for EPS images with bounding box, but pstricks code does not have bounding box specifications. Thus the default media size of ghostscript is used (e.g. letter).

Workaround:

A larger (default) paper size can be set by -sDEFAULTPAPERSIZE=a0 or -sPAPERSIZE=a0. The option can be specified in the entry for dvipdfmx.cfg or on the command line using an environment variable, e.g.:

env GS_OPTIONS=-sDEFAULTPAPERSIZE=a0 xetex test
