Imagemagick: convert tiff to jpg is now creating a stretched, cropped, and partial red only output

[harriott]

I use convert on an almost daily basis for tiffs. Today it didn't work - the original images are ripped towards the right, cropped, and what's left is turned red.

GNU/Linux 5.9.14-arch1-1 with imagemagick 7.0.10.48-1 (two different machines).
Windows 10 Home up-to-date with ImageMagick-7.0.10-48-Q16-x64-static.exe installed.

As my personal tiff files could, since today, not be correctly converted, I investigated further by grabbing a freely available sample image, Sample .tiff download , and on that I tried some conversions:

convert file_example_TIFF_1MB.tiff out.jpg
convert file_example_TIFF_1MB.tiff out.png

Both out-files are failures - I include one here:

Converting an equivalent sample jpg works fine.

Windows 10 Home up-to-date with ImageMagick-7.0.8-3-Q16-x64-dll.exe installed, as was the case for me an hour ago, did the conversions correctly, so this would seem to be a problem introduced somewhere in a very recent ImageMagick update.

Hoping this can be fixed. I love ImageMagick!

With IM 7, use magick not convert. Does that help?

The interlacing pattern looks pretty similar to what I am seeing with #2977...

It fails for me on IM 7.0.10.48, but works fine on IM 7.0.10.49beta Mac OSX Sierra with LIBTIFF, Version 4.1.0. Note that some other bugs in TIFF were fixed in the beta.

Thanks for the problem report. We can reproduce it and will have a patch to fix it in the GIT master branch @ https://github.com/ImageMagick/ImageMagick later today. The patch will be available in the beta releases of ImageMagick @ https://www.imagemagick.org/download/beta/ by sometime tomorrow.

I just built v70.10-50 locally on MacOS Catalina 10.15.7 and can confirm that the below now works as expected:

@urban-warrior Thank you for the quick turnaround. Is there a timeline for when that change will be available via brew?

[urban-warrior]

You'll need to contact the brew team to determine their schedule. We maintain the ImageMagick distribution only.

@fmw42, I've got the update to imagemagick 7.0.10.50-1 before I could check your suggestion.
Everyone else, it's fixed for me now. Thanks @urban-warrior.
