Modify color
Modify color command adjusts the color values of loaded points. The components to adjust are brightness, saturation and gray balance. The process requires that color values are stored for the points. It is normally used after extracting color values from images, for example with Extract color from images command for projects or Extract color from images command for loaded points.
The process supports 3-10 channels were channels 0-2 are the Red Green Blue channels of true-color images.
To modify the color of loaded points:
1. Select Modify color command from the Tools pulldown menu.
This opens the Modify Color dialog:
2. Define settings.
The changes in coloring are dynamically displayed after typing a value in a settings field. If the dialog is closed with Cancel, the original color values are restored.
3. Click OK.
This applies the color modification to the loaded points. Use Save or Save as commands for loaded points in order to save the changes permanently to a file.
