Used in: CONFIG
Parent elements: RASTER_RENDERER

<RASTER_RANGE	Attribute Description Table
*lower ="double"* *upper ="double"* color ="0,0,0 - 255,255,255" [0,0,0] equality ="all \| upper \| lower \| none" [lower] label ="string" [Value of lower or upper] transparency ="0.0 - 1.0" [1.0] > No Child Elements </RASTER_RANGE >
Bold: Attribute or child element is required.

Description:

Defines description and color for a range of pixel values.

Restrictions:

RASTER_RANGE 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.
