Hue Saturation transformation: Hue Change range

Post by pierrelabreche »

Hue Saturation transformation: Hue Change readout is now in degrees instead of percent.
problem : the range is currently +/- 90 degrees.

The range should be expanded to +/- 180 degrees.

I originally had a larger range but it makes it too hard to make small adjustments. Normal hue adjustments are very small.

For creative effects, colors could be substituted all the way to their opposite, e.g. red to cyan.

In the hue slider, as currently implemented, small shifts are easily adjusted by holding the shift key.

Re: Hue Saturation transformation: Hue Change range : slider concept

Post by pierrelabreche »

Hello,

For usability and flexibility, a slider with a data entry box allow the user to enter specific values ( perhaps exceeding the visible scale of the slider ).
Thus, it would be possible to enter values in the range -180 +180 even if the visible part of the slider displays a range of -90 +90.

See point 3 in https://uxplanet.org/4-creative-concept ... 8839b05943

Example use in this page :
https://particuliers.societegenerale.fr ... tionrapide

This slider concept could be used throughout, not just in this transformation

For the next release, the range is -180..+180, but the scale is nonlinear, so it changes slowly near 0.0 and faster for large values.
