[Bug]: ImageMagick 7.1.1-23 fails to open (most) images

[AgentConDier]

Problem description

For some image files, magick will fail to open them:

~ $ magick --version
Version: ImageMagick 7.1.1-23 Q16-HDRI aarch64 21803 https://imagemagick.org
Copyright: (C) 1999 ImageMagick Studio LLC
License: https://imagemagick.org/script/license.php
Features: Cipher DPC HDRI
Delegates (built-in): bzlib cairo fftw fontconfig freetype heic jng jp2 jpeg jxl lcms lzma openexr pangocairo png rsvg tiff webp x xml zlib zstd
Compiler: gcc (4.2)
~ $ magick identify test.jpg
identify: unable to read image data `test.jpg' @ error/constitute.c/ReadImage/991.
~ $ wget https://termux.dev/assets/globals/hosts/hosted-by-hetzner.png

~ $ magick identify hosted-by-hetzner.png
identify: unable to read image data `hosted-by-hetzner.png' @ error/constitute.c/ReadImage/991.

One image that does work are the PNGs generated by adb shell screencap:

~ $ adb shell screencap -p > test.png
~ $ magick identify test.png
test.png PNG 1440x3120 1440x3120+0+0 8-bit sRGB 449713B 0.000u 0:00.000

What steps will reproduce the bug?

~ $ magick logo: test.png
~ $ magick identify test.png
identify: unable to read image data `test.png' @ error/constitute.c/ReadImage/991.

What is the expected behavior?

ImageMagick is able to read and process the image

~ $ magick identify test.png
test.png PNG 1440x3120 1440x3120+0+0 8-bit sRGB 449713B 0.000u 0:00.000

[helpimnotdrowning]

I thought I was going insane since seemingly no one else was having this issue...

Images downloaded from the internet seem to work, but images created by Tasker's Crop function and ffmpeg don't load at all. I'm able to work with them on Windows, howvever.

Example broken image (assuming github upload doesn't reencode it):

[AgentConDier]

Yup, that one doesn't work for me either.

~ $ magick identify image.png 
identify: unable to read image data `image.png' @ error/constitute.c/ReadImage/991.
~ $ md5sum image.png 
48f5939bc1200e150101272167f60138  image.png

Displays fine using timg though.

I don't know if it's related, but it's also my trouble. I can't use chafa, which I was able to use until yesterday. I wonder if it's because I've updated the area around ImageMagick with PKG I came here looking for similar trouble information searching

[~/pyprog]$ chafa
CANNOT LINK EXECUTABLE "chafa": library "libOpenEXR-3_2.so" not found: needed by
/data/data/com.termux/files/usr/lib/libMagickWand-7.Q16HDRI.so in namespace (default)

[~/pyprog]$ python3 plottwo.py

[twaik]

Seems like it was broken during updates. Can you please remind me to trigger rebuild in 8 hours?

[sylirre]

@twaik I tried to rebuild it but that didn't solve the issue

[twaik]

@sylirre what about rebuilding imagemagic?

[sylirre]

I'm saying exactly about imagemagick package.

[sylirre]

Issue with chafa unreproducible.

[Suletta-Majo]

Chafa's problems may be unique to I messed around with a lot of things. 😓 If other people don't seem to have a problem, you can ignore them

[truboxl]

If you can reproduce the chafa issue again, please log new issue. We will see how to fix this imagemagick issue here.

[helpimnotdrowning]

I had some similar issues where a bunch of different programs were complaining about missing libraries a little while ago, it was fixed with pkg upgrade, since I had never done it since I installed termux, maybe that could help?

[Suletta-Majo]

Thanks! Unrelated to the topic my trouble is fixed

Thanks I got some errors on _pkg upgrade_, so I selected all in _termux-change-repo_. As a countermeasure against errors,i'm tryed _apt-get update --fix-missing_ etc. is done as it is said. Chafa on the terminal now shows images as before! Calling from python is the failed, but If you search the net, you will find that the match is bad with the latest 7.x version of imagemagick, which may be a different problem This is the first time I've called it as a program, so it's possible that I'm just writing it wrong _I want to post it folded because it has nothing to do with the agenda, but I don't know how to do it, so I'll leave it as it is, thank you :)_

Same here:

$ wget https://cdn.mobygames.com/182b4910-aba5-11ed-8bb9-02420a000197.webp
$ magick identify 182b4910-aba5-11ed-8bb9-02420a000197.webp
identify: unable to read image data `182b4910-aba5-11ed-8bb9-02420a000197.webp' @ error/constitute.c/ReadImage/991.

If I use ImageMagick in a proot (eg: Alpine) then it works fine, so that's at least a workaround.

[ez-me]

I tried compiling ImageMagick from within termux, and it seems to work perfectly.

I did have an issue with MagicCore/random.c:381 having an implied function, but you can ~remove~ patch that MAGICKCORE_HAVE_GETENTROPY out without too much harm being done (I think).

[landfillbaby]

seems to be fixed in 7.1.1.25?

[superjamie]

Confirmed, working for me in 7.1.1.25

[Suletta-Majo]

in 7.1.1.25 In my environment, it seems that there are things that can be identified and things that cannot be identified

$ magick identify Stest.png
Stest.png PNG 640x360 640x360+0+0 8-bit sRGB 271405B 0.000u 0:00.000
$ magick identify myfig.png
identify: unable to read image data `myfig.png' @ error/constitute.c/ReadImage/991.

What I couldn't identify is a simple test program in my post below
Here's an image of a graph by matplotlib made by python (there is an image in the final post[^1])
https://github.com/termux/termux-packages/issues/18640#issuecomment-1863460919 [^1]: I just confirmed that the image I uploaded to github has changed md5sum
There may be difficulties in using it for verification original md5sum myfig.png 401bc1b1c5b2f6921e17e60368d8e910

It's somewhat similar to the post that illustrates this issue. https://github.com/termux/termux-packages/issues/18740#issuecomment-1866999224 i wonder Maybe the binary header is foreign as a difference normallyPNG?

[AgentConDier]

Yup, 7.1.1-25 seems good. All my previously broken test cases are working again.

[truboxl]

@Suletta-Majo you can zip the image and upload here

[Suletta-Majo]

Thank you I zipped it myfig.zip Perhaps because of the recreate file, the MD5 has changed from the previous one, but the error was the same
usually I don't use ImageMagick directly like this, so I don't have a serious problem. When I tried it, it was an error, so I posted it

这是来自QQ邮箱的假期自动回复邮件。你好，我最近正在休假中，无法亲自回复你的邮件。我将在假期结束后，尽快给你回复。

[landfillbaby]

ok so using unzip myfig.zip && identify -verbose myfig.png in my termux home dir works fine. it might be a permissions thing. what's the output of ls -l myfig.png on the version before zipping?

[Suletta-Majo]

ls -l myfig.png

[288ms][1][~/pyprog]$ ls -l myfig.png
-rw------- 1 u0_a365 20128 Jan  1 23:50 myfig.png
[55ms][~/pyprog]$ ls -l Stest.png
-rw------- 1 u0_a365 271405 Aug 28 07:10 Stest.png

[33ms][~/pyprog]$ magick identify myfig.png
identify: unable to read image data `myfig.png' @ error/constitute.c/ReadImage/991.

If it is possible to identify someone other than myself, it meanings I think it is just that my environment is broken :/
Thank you very much for verifying it I didn't back up my system properly, so I'm going to rebuild my environment from reinstalling termux It's not that difficult because just python and modules :)

P.S after rebuilding a relatively clean termux environment
I was able to display myfig.png information

~ $ magick identify myfig.png
myfig.png PNG 640x480 640x480+0+0 8-bit sRGB 20128B 0.000u 0:00.000

[truboxl]

Ok then I will go ahead and close the issue since everyone agree magick is working now
