equalization A function that brings out details in an image. Equalization
changes the darkest pixels in an image to black and the lightest pixels to white,
then reassigns the remaining pixels to use all of the colors in between. Also
called non-linear contrast stretch.

erase To remove an image insertion from a drawing. This operation removes
the image and frame from the drawing, removes the insertion object and its
color map from the toolspace, but leaves an unreferenced data definition in
the image data view. The color map is not erased from the image data view if
it is used by other insertions. To reverse an erase operation, do a new insertion
from the data definition object. Whether an erased image is also detached
depends on how the Image Detach Options are set on the User Preferences
tab of the Raster Design Options dialog box. See also detach.

ESRI Grid An image format used in ESRI GIS products. This format is available
in ASCII and binary versions.

Export A ProdNameShort operation for saving an image to another file format
and writing out correlation data for the image. The correlation data stores
insertion point, scale, rotation, and density information for the image. When
you export an image, you can save the correlation data to a resource file, a
world file, or to the image file. The type of correlation data you can create
depends on the type of image being exported.

fillet A rounded corner where two lines meet. ProdNameShort can apply fillets
of specified radius to line intersections in bitonal images.

filter An editing tool that can be used to adjust the appearance of an image.
Example: The Invert filter reverses light and dark areas on an image. Also
called editing filter.

FLIC Acronym for the image format Animator FLIC.
follower A vectorization tool that traces raster lines in a bitonal image and
creates vectors that AutoCAD recognizes as individual objects.
creates vectors that AutoCAD recognizes as individual objects.
foreground color The color of the raster objects in a bitonal image. The other
color in the image is the background color.
color in the image is the background color.
frame A rectangular vector object that encloses an image. You can select the
image frame by clicking it, or by using any AutoCAD selection method. The
image frame is an AutoCAD object that you can assign to a layer, reposition,
or scale, using standard AutoCAD methods. A frame can become an irregular
shape if the image is cropped or clipped. See also image frame.

gray: the number of pixels that use the indicated tone.
