Limits Palette

Controls: Spectrum Dialog >> Limits >> Palette
Macro: LimitsPal

Instead of adjusting the individual Red, Green, and Blue color components of the Spectrum Limits display, you may click on Palette to open a standard Windows Color selection dialog. It offers a quick-selection palette, a two-dimensional color map, and separate numerical controls for Hue, Saturation, and Luminance or Red, Green, Blue.

The main drawback of the Windows Color dialog is that it doesn't notify Daqarta of any changes until you exit it, so you can't see the effects on the display while you are adjusting color relationships. The Limits RGB controls are better for that, because changes show up immediately.


Macro Notes:

If the Spectrum Limits dialog is open, LimitsPal= (value ignored) opens the Windows Color dialog. Once open, this can only be closed manually, not via macro control.
