Seadisp Load True Color Image File Widget

The Load True Color Image File Widget

Description: This procedure loads true color images from either 1) an external SeaWiFS L1A, L2, or true color TIFF file or 2) from currently loaded bands.

Notes:

True color images can't be rescaled once loaded.
There is no hard-coded limit to the number of files loaded into memory at one time. The only limit is the memory limit of your machine.
