NAME
r.compositeDESCRIPTION
This program combines three raster map layers to form a composite RGB layer. For each layer, the corresponding component from the layer's color table is used (e.g. for the red layer, the red component is used, and so on). In general, the layers should use a gray-scale color table.NOTES
The default number of intensity levels for each component is 32, resulting in a total of 32768 possible colors (equivalent to 15 bits per pixel). If significantly more levels than this are used, not only will r.composite take longer to run, but displaying the resulting layer with d.rast will also be significantly slower.Floyd-Steinberg dithering is optionally used.
