regression completely disabling -quality parameter for webp

[johnkw]

ImageMagick version

67 works, later versions fail

Operating system

Linux

Operating system, version and so on

any

Description

This seems to pretty obviously be due to a0bd172 which deleted the quality variable entirely some time after version 67.

A very similar patch to another branch seen here probably works: ImageMagick/ImageMagick@3331c9e

Steps to Reproduce

convert to webp and use -quality parameter

See bug #6204 for source of regression.

Thank you for reporting the issue. We have successfully reproduced it and are actively working on a patch to resolve it. You can expect this patch to be merged into the main GIT branch, later today. As part of our commitment to quality, this fix will also be included in the upcoming beta releases of ImageMagick by tomorrow. Your patience and feedback are greatly appreciated.
