Autotek autocad raster design 2010 用户手册

1 Click Image menu  ➤  Insert. Navigate to Raster Design\Samples, and

insert the image elev_small.dem into your current drawing.

2 In the Image Manager toolspace, expand the object tree under the image

elev_small, right-click the color map, and click Edit Color Map.

3 In the Palette Assignment Color Map dialog, select the color map that is

used in your primary image.

4 Adjust the size and location of the elevation key in relation to the primary

DEM image.

You can insert another copy of an image when you want to use a different
type of color map or make other display changes.

When you create another insertion of an AutoCAD image object (bitonal,
grayscale, index color or true color), you use the same type of color map,
which you can edit later.

Some of the custom image types that Raster Design handles can use two or
three different types of color maps, and the only place where these options
are presented is on the 

 (page 332) view of the Image Manager

toolspace, when you right-click the image data definition. If you right-click
an existing color map, you can create a new image insertion using the same
color map type.

When the image data definition is in single-band integer format, such as
IKONOS 16-bit, a new insertion can use either a grayscale or palette color
map.

When the image data definition is multispectral, a new insertion can use a
grayscale, palette color, or false color map.
