Notes
- This function supports only 8-bit raster inputs.
- You can assign an existing attribute table with your color scheme, or you can create a new color attribute table.
- If your table contains fields named Red, Green, and Blue, values within those fields will be used like a color map when rendering the image.
- The attribute table is referenced when using this function even when it is not stored in the dataset, such as with raster datasets that contain internal attribute tables.
- When the dataset is displayed, it can be symbolized based on the table values. When a pixel is queried, the table values will be returned.
