Issue
Temperature has Tint effect, not temperature.
It shall be either renamed to Tint or reworked to cold/warm effect.

Actual behaviour:

• temperature
  min - green
  max - purple

Expected behaviour:

• tint (rename Temperature to Tint)
  min - green
  max - purple

• temperature (add new Temperature effect)
  min - blue (cold)
  max - yellowish (warm)

Examples
This is how temperature/tint effect works in other programs:

• Tint
  • Lightroom

    

  • ACDSee

    

• Temperature
  • Lightroom

    

  • ACDSee

    

Note: programs have some difference in representing Temperature/Tint for JPEG/RAW

• Lightroom
  different sliders scale:
  • JPEG - Temp and Tint -100 to +100
  • RAW - Temp (2000-50000) and Tint (-150 – +150)

• ACDSee
  no change in sliders scale, but added info in Kelvins

hi, Pierre, what about this issue/suggestion?

could you send me the picture used?

sure, but this effect is the same for all files I have
ps. also just noticed that Temperature does not affect 8-bit images at all (eg save this file as .gif).
I remember you have mentioned that (some) filters do not work with 8-bit images, but speaking about 'Enhance colors' dialog it looks strange that only Temperature has no effect on such images.

See issue for current status and some details.

This problem is supposed to be fixed in XnView MP 1.4.4. Please check and confirm the bug fix here.

fixed in 1.4.4
