Scale
Enter a default numeric scaling factor for images. For example, to make the
image twice as large, enter 2 in the Scale box.
Density
Density
Type a default density (or resolution) for images. You should set the this
value to the most common density value at which your images are scanned.
Insertion Point and Density Units list
Select the default insertion point and density units for the images. For
example, a common North American scanning resolution is 300 dpi (300
dots per inch). To set this value as your default density, type 300 in the
Density edit box and select inches as the Units. If you insert images that
have density value and density unit information stored in the correlation
source, then these defaults are not used.
For an illustration of how to set the density value and units for an image,
see
Setting Image Density (page 467).
Memory
Use the Memory tab to specify the amount of memory (RAM) that AutoCAD
Map 3D can use for images before using a temporary swap file. You can also
define the location of the temporary swap file.
Temporary File Location
