Changing a color-mapped raster layer to use the RGB renderer

If your raster has a color map, it is displayed with the Colormap rendered by default. You can change this to use the RGB renderer.

  1. Click the Add Data button Add Data to add a raster to ArcMap.
  2. Click Windows on the Main menu to view the Image Analysis window, and click Image Analysis.
  3. Click the raster layer in the Image Analysis window.
  4. Click the Colormap to RGB button Colormap To RGB in the Processing section of the window.

    This adds a temporary raster dataset layer to the table of contents.
