Bug ID 553741: Restore WAM image optimization color profile handling

Last Modified: Sep 13, 2023

Affected Product(s):
BIG-IP WAM(all modules)

Known Affected Versions:
12.0.0, 12.0.0 HF1, 12.1.0 HF1, 12.0.0 HF2, 12.1.0 HF2, 12.0.0 HF3, 12.0.0 HF4, 12.1.1 HF1, 12.1.1 HF2, 12.1.2 HF1, 12.1.2 HF2

Fixed In:
12.1.0

Opened: Oct 21, 2015

Severity: 3-Major

Symptoms

In version 12.0, a component of WAM's image optimization software accidentally built without the color management library.

Impact

The color profile would be removed but color values would not be adjusted accordingly. Depending on the color profile and the image, this may or may not result in visible differences.

Conditions

WAM image optimization enabled with format conversion or the jpeg option "apply color profile, then strip EXIF" enabled.

Workaround

Don't let WAM's image optimization convert image formats (including to browser-specific formats WebP and JPEGXR) and use "strip EXIF if safe" instead of "apply color profile, then strip EXIF".

Fix Information

The color management library and functionality has been restored.

Behavior Change

Restores correct color management to WAM's image optimization feature.
