Macros: SgTopNum, SgTopRed, SgTopGrn, SgTopBlu, SgBotNum, SgBotRed, SgBotGrn, SgBotBlu

These controls set the range over which Daqarta will create a color gradient in the palette. You may enter index values between 0 and 255 directly, or click on the desired color in the color bar and then click on the color square next to the index control.

The color square always shows the current color assigned to the index. Below the color square and index control are separate Red, Green, and Blue (RGB) component controls. These always show the components that make up the current color. They may be adjusted to change the current color, but only if Lock Palette is off.

If Lock Palette is off, Daqarta will compute a new gradient between the Top Index and Bottom Index settings whenever there are any changes, either to an Index or to its RGB values.

The controls for Top Index and Bottom Index are identical. There is no need to insure that Top Index is actually higher than Bottom Index, since Daqarta will sort things out internally.

See the Spectrogram Color Palette Dialog discussion for examples of how to use Top Index, Bottom Index, and their RGB controls.

Macro Notes:

SgTopNum=100 sets the Top Index to 100. SgTopNum=>1 increments the current value by 1, and SgTopNum=>-1 decrements by one.

SgTopRed=128 sets the Top Red component to 128. SgTopRed=>1 increments and SgTopRed=>-1 decrements this value. SgTopGrn and SgTopBlu control the Green and Blue components.

SgBotNum, SgBotRed, SgBotGrn, and SgBotBlu work similarly for the Bottom Index.

Note that when Lock Palette is active, the Red, Green, and Blue component values can not be changed via macro. Attempts to do so may cause the macro to abort with an error message. Use SgLock=0 before color component commands.
