If reverted to [email protected]+3, it is:

It turns out this version also breaks TIFF loading:

julia> using ImageMagick, TestImages

@staticfloat if possible, could you help investigate this?

FYI: bisected the test failures to https://github.com/ImageMagick/ImageMagick6/commit/a1a71cb6c494c98808a91a23224451667cf719e1

Edit: TIFF loading is a separate issue unfortunately, so simply reverting that commit is not enough

[ViralBShah]

The PNG stuff here seems to work correctly now with ImageMagick 6.9.12. The TIFF stuff still has the same error. There's also 6.9.13 upstream, which perhaps fixes the TIFF issue. Is that worth trying?

On M1, the bigger issue is that 6.9.10 is too old and doesn't work at all.

[giordano]

There's also 6.9.13 upstream, which perhaps fixes the TIFF issue. Is that worth trying?

I simply tried

but I still get

For the record, our [email protected] currently corresponds to upstream version 6.9.13-6: https://github.com/JuliaPackaging/Yggdrasil/blob/24010c93241559f44b967496e65782a9d18729f0/I/ImageMagick/ImageMagick%406/build_tarballs.jl#L5. I guess someone will have to report the issue upstream with a C reproducer, otherwise no one will look into this.

[giordano]

Actually, this seems to be https://github.com/ImageMagick/ImageMagick/issues/2015, which is apparently a bug in libtiff, still open: https://gitlab.com/libtiff/libtiff/-/issues/110. https://github.com/ImageMagick/ImageMagick/issues/2015#issuecomment-1445173147 suggests

I used the workaround of first running the images through tiff2rgba (which strips those unknown tags, apparently), and then running convert on them.

Maybe we can do something similar? What's tiff2rgba?

[mrAceT]

I have the same problem.

I decided to upgrade ImageMagick 6.9.12-93 Q16 x86_64 17898 to ImageMagick 6.9.13-14 Q16 x86_64 18442

But that had no effect.

On an old test server I have ImageMagick 6.8.9-9 Q16 x86_64 which is working perfectly.. quite frustrating!

[ViralBShah]

Is it possible that PNGFiles.jl is doing something that is non-standard or buggy that is leading to this issue?

For example: https://github.com/JuliaIO/PNGFiles.jl/issues/48

[dgleich]

Okay, there are two different issues here. The start of the issue was the PNG file breaking. Then it also moved to include the TIFF file breaking.

On the new main version that I updated to ImageMagick 7.1, it fixes the PNG file issue. But leaves the TIFF file issue.

[dgleich]

Notes on the tiff issue:

https://imagemagick.org/discourse-server/viewtopic.php?t=36263

https://github.com/ImageMagick/ImageMagick/issues/7185

https://gitlab.com/libtiff/libtiff/-/issues/532

https://stackoverflow.com/questions/64239390/imagemagick-identify-fails-for-tiff-files

So this seems to be a recurring issues for ImageMagick and libtiff.

My plan at the moment is to make a list of these tags and just setup the ImageMagick reader to ignore them. This should broadly work. They aren't 'file supported'

Addressed in https://github.com/JuliaIO/ImageMagick.jl/commit/1411a8a86990e155c4e544cfade5ff8c2bae1b9a

[ViralBShah]

Closing since we are now on ImageMagick 7 on master.
