#418 regression in test t/357_unpaper_rtl.t

[Florian Brandes]

Hi,

there seems to be a regression in gscan2pdf-2.13.2:

t/356_unpaper_corrupt_image.t ................. ok   
t/357_unpaper_rtl.t ........................... 2023/04/20 04:01:01 [image2 @ 0x448700] Encoder did not produce proper pts, making some up.
[image2 @ 0x448700] The specified filename '/build/KL5kTVnNCi/vlO74czl2x.pnm' does not contain an image sequence pattern or a pattern is invalid.
[image2 @ 0x448700] Use a pattern such as %03d for an image sequence or use the -update option (with -frames:v 1 if needed) to write a single image.
[image2 @ 0x452940] The specified filename '/build/KL5kTVnNCi/JbUyV_hVUO.pnm' does not contain an image sequence pattern or a pattern is invalid.
[image2 @ 0x452940] Use a pattern such as %03d for an image sequence or use the -update option (with -frames:v 1 if needed) to write a single image.
convert: negative or zero image size `/build/KL5kTVnNCi/YfgegFM53e.pnm' @ error/resize.c/ResizeImage/3743.
*** unhandled exception in callback:
***   "convert" unexpectedly returned exit value 1 at t/357_unpaper_rtl.t line 63.

The full build log is available at https://hydra.nixos.org/build/216769307/nixlog/1

Versions:
unpaper-7.0.0
imagemagick-7.1.1-7

It seems the build succeeded with imagemagick-7.1.1-6 which would suggest a regression due to an update of imagemagick.

I was about to report the same; for cross-reference here the nixpkgs issue for it: https://github.com/NixOS/nixpkgs/issues/227265

[Jeffrey Ratcliffe]

Thanks for the reports. Does that version of convert produce reasonable output for the following:

convert +matte -depth 1 -border 2x2 -bordercolor black -family 'DejaVu Sans' -pointsize 12 -density 300 label:"The quick brown fox" 1.pnm
convert +matte -depth 1 -border 2x2 -bordercolor black -family 'DejaVu Sans' -pointsize 12 -density 300 label:'The slower lazy dog' 2.pnm
convert -size 100x100 xc:black black.pnm
convert 1.pnm black.pnm 2.pnm +append test.pnm
convert test.pnm -depth 1 -resize 1x1 txt:-

?

[Joachim Breitner]

The last command says something on stderr, and returns with non-zero status.

/tmp/foo $ convert test.pnm -depth 1 -resize 1x1 txt:- > /dev/null
convert: negative or zero image size `test.pnm' @ error/resize.c/ResizeImage/3743.

[Jeffrey Ratcliffe]

As test.pnm doesn't have a negative or zero image size, it looks like a bug in imagemagick to me.

Reported at https://github.com/ImageMagick/ImageMagick/issues/6287

[Joachim Breitner]

Fixed upstream in 7.1.1-8.

[Jeffrey Ratcliffe]

Thanks for the update. Does that mean that I can close this?

[Joachim Breitner]

Yes, I think so. Thanks!
