I personally would argue that having slower image scaling to be accurate to a given gamma would most of the time be a negative effect, especially in the context of a web browser. However it is true that most images are handled in a color space using gamma so mis-rendering of images is possible if not gamma-corrected in the colorspace used by the image. From what I understand if the image does not provide the gamma used (or otherwise define it) a good default choice is gamma = 2.2. -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.
