AlmaLinux 9.4 Distribution contains convert app but unlike the convert in Centos it does not convert tif images with > 4 Channels properly.
By using convert source.tif -resize 400 x 400 -colorspace rgb output.tif the output is a black image even the source shows a normal image
By checking the source image with tiffinfo it shows only 10 channels even the file got 16 channels.
Any idea to overcome this issue?
First, the 9.4 is no longer supported. Currently AlmaLinux 9 is 9.7.
One can dnf up to get the latest updates.
The convert is a tool in ImageMagick package.
CentOS 7 did have ImageMagick (with last version being 6.9.10.68-7.el7_9).
AlmaLinux 9 does not have ImageMagick. EPEL 9 does.
EPEL is Extra Packages for (all) Enterprise Linux distros. A third-party repo.
It has now ImageMagick version 6.9.13.25-1.el9
If the issue is in the package built by EPEL, then create a bug report to EPEL. See Making sure you're not a bot!
Thx for the feedback
