What version of Magick is being used?

[Llaves]

I posted a question earlier regarding a color shift when images are resized for thumbnails or other reasons. This appears to be a known issue with earlier versions of Image Magick having to do with the non-linear nature of gamma in sRGB space. I just downloaded the latest version of Image Magick and tried resizing one of the images that had a very visible color shift when uploaded to my Lychee site. The new version (7.1.2-8) automatically handles gamma conversions when resizing and shows no noticeable color shift when resizing that same image.

How do I find the magick version in Lychee? If it's an older version, is there a way to install a newer version, or is that baked into the PHP module that provides magick support?

It is this one, backed into the php module:

It would appear this is:

ImageMagick version info is:
versionNumber = 0x710
versionString = ImageMagick 7.1.0-57 Q16-HDRI x86_64 d68553b17:20221230 https://imagemagick.org

I tried 7.1.0-60 on my laptop (couldn't find -57) and the color shift is not appearing when I resize an image using the -resize command.
I installed Lychee using Softaculous and it shows Lychee version 6.9.2 with a date of 10-11-25, which presumably is using ImageMagick 7.1.0-57.
I suppose the problem could lie in how the PHP library is calling the resize command in the underlying Image Magick installation.
I've posted this as an issue to the imagick library repo.
