Summary
Adds a new color map or replaces an existing color map on a raster dataset.
Usage
The color map applied to the input raster dataset can originate from a raster dataset that already has a color map, a .clr file, or an .act file.
This tool will not work when the color map is internally stored in the attribute table of an IMG or a TIFF dataset. If the attribute table contains the fields Red, Green, and Blue, that means this tool cannot be used.
The input raster dataset must be a single band raster dataset with integer values. Color maps can only be created for single-band raster datasets with a pixel depth of 16-bit unsigned or fewer. Certain formats cannot have a color map associated with them; please consult Supported raster dataset file formats.
Syntax
AddColormap(in_raster, {in_template_raster}, {input_CLR_file})| Parameter | Explanation | Data Type |
in_raster | The raster dataset to add or replace a color map. | Raster Layer |
in_template_raster (Optional) | A raster dataset that has a color map that you want to apply to the input raster dataset. If this is entered the input_CLR_file parameter is ignored. | Raster Layer |
input_CLR_file (Optional) | Specify a .clr or .act file to use as the color map. | File |
Derived Output
| Name | Explanation | Data Type |
| out_raster | The output raster dataset. | Raster Layer |
