Spectrogram Lock Palette

Macro: SgLock

When this is active, the RGB color controls are disabled and greyed. Top and Bottom Color Index are still active and may be set as desired to see current RGB settings for any index, but the palette itself will not change.

See the Spectrogram Color Palette Dialog discussion for an example of how to use Lock Palette for modifying only a portion of a palette.


Macro Notes:

SgLock=1 sets the Lock state, SgLock=0 unlocks, and SgLock=x toggles between locked and unlocked.
