<RASTER_EXACT	Attribute Description Table
*value ="double"* color ="0,0,0 - 255,255,255" [0,0,0] label ="string" [Value of index] transparency ="0.0 - 1.0" [1.0] > No Child Elements </RASTER_EXACT >
Bold: Attribute or child element is required.

Description:

Defines description and color for one pixel value.

Restrictions:

RASTER_EXACT can be used in map configuration files only and 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. Supported formats are ArcSDE raster, GRID, BIL, and BSQ.
- 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.
