[Bug 1932297] Re: 8:6.9.7.4+dfsg-16ubuntu6.11 break pcx 1bit creation

2021-06-22 Thread Georg Pelz
I found a workaround by using an intermediate file which works with
20.04 and on my 18.04 system.

first crop, but output to .gif using:
convert -crop 1200x800+1+1 +repage -rotate 180 -crop +2+1 +repage -rotate -90 
-bordercolor white -border 1x1 -resize 1200 
upsversandauftrag_etikett_1848655-1_test.gif -colorspace Gray -depth 1 -colors 
2 -depth 1 upsversandauftrag_etikett_1848655-1_bw.gif

file upsversandauftrag_etikett_1848655-1_bw.gif 
upsversandauftrag_etikett_1848655-1_bw.gif: GIF image data, version 89a, 1200 x 
1800

then convert the new .gif to pcx using:
convert upsversandauftrag_etikett_1848655-1_bw.gif 
upsversandauftrag_etikett_1848655-1.pcx

file upsversandauftrag_etikett_1848655-1.pcx
upsversandauftrag_etikett_1848655-1.pcx: PCX ver. 3.0 image data bounding box 
[0, 0] - [1199, 1799], 1-bit colour, RLE compressed

-> no clue, why the additional step is necessary, but it fixes the issue for me.
May be the workaround also helps to figure out what changed in imagemagick that 
breaks the direct gif->pcx conversion with the cropping

I can reproduce it on 20.04, but it's not a regression caused by a
security update. This is the original package 20.04 shipped with:

2021-06-21 Thread Georg Pelz
Okay, I tried it on another 18.04 system and there the calls work
properly.


When running the calls on my desktop system (20.04) I get:
$ dpkg -l | grep imagemagick
ii  imagemagick   
8:6.9.10.23+dfsg-2.1ubuntu11.4 amd64image manipulation 
programs -- binaries
ii  imagemagick-6-common

programs -- infrastructure
ii  imagemagick-6.q16 
8:6.9.10.23+dfsg-2.1ubuntu11.4 amd64image manipulation 
programs -- quantum depth Q16

$ convert -crop 1200x800+1+1 +repage -rotate 180 -crop +2+1 +repage
-rotate -90 -bordercolor white -border 1x1 -resize 1200
upsversandauftrag_etikett_1848655-1_test.gif -colorspace Gray -depth 1
-colors 2 -depth 1 -colorspace Gray
upsversandauftrag_etikett_1848655-1.pcx

$ file upsversandauftrag_etikett_1848655-1.pcx
upsversandauftrag_etikett_1848655-1.pcx: PCX ver. 3.0 image data bounding box 
[0, 0] - [1199, 1799], 3 planes each of 8-bit colour, RLE compressed

so there I got the issue too. :/


-> I'll do some more and try to figure out what the difference between my two 
18.04 server systems is. But from the looks of it, it's something unique to 
some of my systems and not a general imagemagick bug like I feared.

Thanks for checking.

Thanks for reporting this issue. I am going to need a test image to
reproduce this. I tried reproducing it with some gif test images, but
didn't not manage to find one that displays the broken behaviour.

this also happen on Ubuntu 20.04.2, so my guess is that this is
something that was introduced after ubuntu6.9
