This function uses the statistics from the rasters within the mosaic dataset; therefore, if you use this function, you must make sure statistics have been calculated.

The stretch type defines a histogram stretch that will be applied to the rasters to enhance their appearance. Stretching improves the appearance of the data by spreading the pixel values along a histogram from the minimum and maximum values defined by their bit depth. <\/div>", "tags": [ "System Raster Function", "Raster Function Template", "Appearance", "Stretch" ], "snippet": "Enhances an image by adjusting the range of values displayed.
