acro4_gs811.tar.gz
Wanted to run it with CPSI, but could not unpack the TAR file on Windows. gzip suceeds but tar fails. Could you re-pack it please ? I've got the files from Alex. CPSI renders both files fine. I confirm the problem with Ghostscript. GS_7_0X renders fine. gs8_00 renders it fine. Interesting that in the wrong rendering with CVS HEAD the lower bounary of a character bbox appears equal to the upper boundary of the correct rendering with gs8.00. Created attachment 385 [details]
acrobat4-.eps
Attacing a reduced test.
This problem was introduced on 2003-01-27 with activation of the new hinter. The test document embeds a font, which has a big Y component of lsb. The old code (NEW_TYPE1_HINTER 0) ignores the y-component of lsb with the command ce1_sbw. I have no idea why it was done so. The new code (NEW_TYPE1_HINTER 1) does not ignore it, and we get the shift. The previous comment isn't correct. The old code accounts the Y coordinate at the end of gs_type1_finish_init. Still didn't find where the new code diverges. Well, I found the reason. The new hinter imports the side bearing when import_shift is not initialized. Need to initialize it in t1_hinter__init rather than in t1_hinter__set_mapping. Created attachment 386 [details]
