    Detailed Description

    The blend renderer extends HillshadeRenderer with options to provide minimum and maximum stretch values, gamma adjustments, elevation raster, and color ramp. It provides a look similar to the original raster, but with some terrain shading, giving it a textured look and making changes in elevation more visible.
