raster impact point The point where a vector polyline intersects a raster
entity.
raster object A distinct line, circle, or arc in a bitonal raster image. Raster
objects can be vectorized or edited using raster entity manipulation.
raster pen A ProdNameShort tool that allows thickening of vector objects
when you merge them into the image. Thicknesses are assigned according to
the specified entity color.
raster snap A setting that automatically places the cursor at the end, center,
corner, intersection, or edge points on a bitonal raster entity. If you choose
more than one snap mode, then the crosshairs snap to the closest of the
possible snap points.
resolution The number of dots per unit at which an image is scanned or
created. Example: An image scanned at 600 dots/inch (dpi) has a higher
resolution than one scanned at 300 dpi.
resource file A file used by ProdNameShort to store image correlation data
such as insertion point location, scale, and rotation. Resource files have a .res
extension. They can be created by the Export command and can be read only
by ProdNameShort. See also world file.
RFT Revisable form text.
RGB Red-green-blue color channels.
ringing artifacts A loss of image detail that can occur with image compression
and resampling techniques. The symptoms include ripples or similar
interference along edges where two dissimilar colors meet. The sharpness of
the edges is degraded.
RLC Run-Length Coding raster image format. ProdNameShort can read RLC1
and RLC2. RLC 1 is a plain RLC with no header. RLC2 is an RLC1 with IST
headers. See also run-length coding.
RLC2 Run-Length Coding raster image format with IST headers. See also
run-length coding.
rotation angle The angle at which an image is being revolved about its axis.
RTF Rich text format
rub To remove a line or area from an image with a ProdNameShort Rub
command (e.g., irubline, irubarc). A rub changes the pixels in a selected area
to the transparency color. When transparency is turned on for the image, the
rubbed area becomes transparent. Rub permanently alters your image.
