gdbinit to trace TrueType rasterizer in ghostscript
I suppose you received some error messages like:
"Failed to interpret TT instructions for glyph index 40 of font
JEPCJL+NancyBlueFC-GrasObl. Continue ignoring instructions of the font."
when ghostscript tries to render the missing character.
By attached gdbinit, I found that TrueType rasterizer in ghostscript
got a stack overflow error. xpdf using FreeType2 font rasterizer can
display the problematic font by expected form "READING". I will
investigate in more microscopic level.
BTW, the sample PDF is encrypted and slightly difficult to edit
manually. If possible, please upload unencrypted sample or raw
TrueType font NancyBlueFC-GrasOblique? (if it's permitted to
upload onto public web site).
If you re-distill a PDF with gs, the encryption will go away. You are right. The error is: "GPL Ghostscript 8.61: Failed to interpret TT instructions for glyph index 40 of font JEPCJL+NancyBlueFC-GrasObl. Continue ignoring instructions of the font." Sorry , I've found this bug only with this File (downloaded from internet...) Created attachment 3703 [details]
