They no longer % have the time, interest, or current expertise to keep this code working. % If you find bugs, please send proposed fixes to bug-gs@ghostscript.com. % % Bug fix 2002-04-20 by rayjj: Bounding box was incorrect since it depended % on the dither pattern and gray shade at the boundary. Changed to use % 8-bit grayscale preview image to allow correct bounding box (at the % expense of a 8x larger preview image). Also moved .setsafe until after % the device and file operations are complete (but still before the input % file is processed. % Bug fix 2000-04-11 by lpd: if a font didn't have a FontName (which is the % case for bitmap fonts produced by recent versions of dvips), setfont % caused an error. % Bug fix 8/21/99 by lpd: many of the margin and width computations were % wrong (off by 1). The code only "worked" because the bugs were % (mostly) in conservative directions. % Modified 3/17/98 by lpd to make it possible to run this file without % running the ps2epsi script first, for debugging. % Bug fix 9/29/97 by lpd <ghost@aladdin.com>: if the page size wasn't an % exact multiple of 8 bits, an incorrect bounding box (or a rangecheck % error) could occur. % Patched 7/26/95 by % Greg P.
