ContrastBrightness

Zusammenfassung

Creates an enhanced image by improving the contrast and brightness of the source image.

This function works on an 8-bit input raster only.

For more information about how this function works, see the ContrastBrightness raster function.

The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.

ContrastBrightness(raster, {contrast_offset}, {brightness_offset})

Parameter	Erläuterung	Datentyp
