StretchRenderer

A stretch renderer enhances the visual contrast of raster data in a RasterLayer. A stretch renderer uses continuous raster cell values across a gradual ramp of colors to visualize raster data. It works well when you have a large range of values to display, such as in imagery, aerial photographs, or elevation models.

Stretching improves the appearance of the raster data by spreading its cell values along a histogram whose minimum and maximum values are defined by the raster's bit depth. For example, an 8-bit raster dataset will be stretched along a histogram from 0 to 255.
