(m): Child element can be used multiple times.

Description:

Renders images by classifying pixel values.

Restrictions:

RASTER_RENDERER is not available from the ArcIMS Author interface.
Raster renderering is available in all viewers. However, labels in the legend are valid only in HTML Viewers.
A value cannot be duplicated in a raster renderer. If a duplicate is detected, an error message is returned.
Valid with Image Server only.

Notes:

Three methods are available to define colors in an image.
- ArcSDE colormap or CLR file, which pairs a value and a color. The value is included in the legend.
- Table in ArcSDE that pairs a value with a color and description. The description is included in the legend. If no description is available, the value is used instead. If a table is used, the colormap is ignored.
- The RASTER_RENDERER elements. If these elements are used, any colormaps or ArcSDE tables are ignored.

Examples for RASTER_RENDERER:

Example 1: When in a map configuration file.
