MODIFYCT Procedure

Standard Library procedure that lets you replace one of the PV-WAVE color tables (defined in the colors.tbl file) with a new color table.

MODIFYCT, table, name, red, green, blue

table The color table number to change. The numbers range from 0 to 15.

name The name of the modified color table. The string may be a maximum of 32 characters.

red The red color gun vector. It contains 256 elements.

green The green color gun vector. It contains 256 elements.

blue The blue color gun vector. It contains 256 elements.

Ctfile Specifies a string containing the name of a color table file to load.

Since any changes to the system color tables will affect all users, this procedure should be reserved for a single individual at a PV-WAVE site with authorization to make system modifications. It is also a good idea to make a copy of the colors.tbl file prior to using MODIFYCT.

HLS, HSV, HSV_TO_RGB, LOADCT, RGB_TO_HSV
