New Revision: 8448

Modified:
   trunk/gs/src/gdevpdf.c
Log:
Fix (pdfwrite): PDFXTrimBoxToMediaBoxOffset used the supplied data
incorrectly.

Details:
Bug #689578 "PDFXTrimBoxToMediaBoxOffset".

Patch supplied by Adam Augusta.

(gdevpdf.c) pdf_write_page. When using the PDFXTrimBoxToMediaBoxOffset
data, we need to subtract the bottom right offset from the MediaBox
not add it, the trim box must lie inside the media (see Acrobat 7.0
distiller parameters manual, pp. 102-103).

EXPECTED DIFFERENCES:
None.
