| Summary | 0000991: context+cowfont generates pdf that cannot be read by ghostscript | ||||
| Description | running "context cow.tex" on the attached file (it just typesets a Q in the cow font) results in a pdf that gs cannot read. gs cow.pdf reports: **** Error reading a content stream. The page may be incomplete. Output may be incorrect. and the gs output window is empty. (i don't really care about gs per se, but gs --bbox fails in the same way, thus pdfcrop cannot work, which was a pain.) whether this is a bug in the cow font, luatex, or ghostscript, i don't know. i tried a variety of gs versions and they all failed. since the cow font is so unusual, i thought i'd report it here first. | ||||
| Steps To Reproduce | context cow.tex gs cow.pdf | ||||
| Additional Information | 1) this is actually with current context-minimals, luatex version 1.0.0, but your "product version" field does not offer that as an option :). 2) not every use of the cow font results in this error. i have a 12-page document; 3 pages are bad (2, 4, and 12), the rest are fine. (running pdfcrop on the 12-page pdf will report the problematic pages.) i can send that also if you want the additional examples, or maybe the ui here will let me add it to this report after i submit it ... | ||||

p.s. barbara reports the current version of acrobat professional (not just reader) reports "An error exists on this page. Acrobat may not display the page correctly.". It provides no other details, but it does lend support to the bug in luatex/cowfont hypothesis, vs. being in ghostscript. nothing's for sure, of course. hope you can investigate ... tx. |

The page stream looks odd on my side as well: 9 0 obj << /Length 199 >> stream 0 g 0 G 0 g 0 G q /Span << /ActualText <feff0051> >> BDC [<feff>] TJ 1.000000 g BT /F5 11.955168 Tf 1 0 0 1 70.867 701.98286 Tm [<0145>]TJ 0.000000 g 1 0 0 1 70.867 701.98286 Tm [<0030>]TJ ET EMC Q endstream It seems GS complains about the [<feff>] TJ: if I replace that bit by space characters, GS is happy |

I came to the same conclusion and removed that hack. We introduced that when we were testing cut/paste in viewers other than acrobat. So, instead of that hack, we now just wait till the open source viewers get better. Btw, I will look onto the "/F5 flushing earlier and not interfering with literals" case later (as I didn't want to mess with the vf backend around 1.0 release). |

i'll add a bit more control over virtual command flushing |
