Description Flavio Grossi 2019-03-15 14:23:47 UTC
Created attachment 1544483 [details]
test image

Description of problem:
Converting an image to fax results in a blank page. Should be related to #1633602, since it used to work before the changes discussed in that bug report.

Version-Release number of selected component (if applicable):
ImageMagick-6.7.8.9-16.el7_6.x86_64

How reproducible:
Always

Steps to Reproduce:
1. download the attached image
2. convert the image using convert -compress Fax 83902442-88f7-4251-8318-8b77d9fa954b.jpg output_image.tiff
3. open output_image.tiff

Actual results:
the converted image is a white page

Expected results:
a non-white page

Additional info:
using ImageMagick version 6.7.8.9-15.el7_6.x86_64 works correctly.
Judging from the rpm spec the culprit may be the patch discussed in #1633602

Comment 2 Flavio Grossi 2019-03-28 13:10:12 UTC
any news on this one?

For now we have downgraded the packaged and everything works fine, but also dropping the patch rhbz1633602-quantize.patch works too.

Thanks for the report, there's a simple reproducer and we can fix this.
