Assigning a new PCT to the current session

Use the PCT window to change the pseudocolor table assigned to the current aggregate session. You assign a new PCT in two ways: by generating it (Generate PCT) or by importing it (Import PCT).

Generate PCT creates a PCT that attempts to simulate a reference RGB image. Duplicating the look of an RGB image may assist you in identifying and locating areas within the image to be aggregated. Use Import PCT if you want to import an existing PCT.

From the Aggregate window, click PCT in the Input Classes area.
To generate a PCT, do the following:
1. In the PCT window, click the Generate PCT tab.
2. For each of the red, green, or blue channel designations, select a channel from the Channels available list.
To import a PCT, do the following:
1. In the PCT window, click the Import PCT tab.
2. Click File.
3. In the File Selector window, locate and select the file containing the PCT segment you want to import, and click Open.
4. Click Open.
5. In the PCT window, select a segment in the list.
Click OK.
