LUT, PCT, and GCP segment

Lookup Tables, Pseudocolor Tables, and GCPs items have a Data item that displays the actual data of the selected segment. If the file is writable, and if the file-format type supports writing to the selected segment type, the data can be modified.

To modify the data, in the uppermost pane, select the segment item, and then in the lowermost pane, click the appropriate table cell. Type a new value, and then to save your changes, press Enter (or click outside the table).

Pseudocolor Tables

When you select a PCT segment, the title of the lowerpost pane changes to Pseudocolor Table Information, and the table displays the color of each RGB entry. To change the color of an RGB entry, click cell of the color you want to modify, then select the color you want.

GCPs

When you select a GCP segment, the title of the lowermost pane changes to GCP Information, and the table displays standard information about the segment. The Type column indicates whether each point is a ground control point or a check point. Additionally, the GCP segment's System 2 georeferencing string is displayed. If the file is writable, you can modify the string.
