Raster Graphic
Images
Also called "Bitmapped Graphics," are defined by one or more
pixels among the many in the grid of pixels that compose the
display area of the screen.
Rasterfiles
SUN Microsystems graphics data-format.
Raw Custom
General graphics data-format.
Raw RGB
General color graphics data-format for RGB-type pictures. The filename extension is: .RGB. Red, Green and Blue values are stored with each pixel.
The size of an uncompressed image is equal to its total size divided by its width multiplied by its height (T/(W*H). Pixel values are read from left to right or high bit to low bit. Pixel depth examples: If 2 bytes per pixel, then 1 "junk" byte, 5 bits for red, 5 bits for green and 5 bits for blue. If 3 bytes per pixel, then 1 byte for red, 1 for green and 1 for blue. If 4 bytes per pixel, then 1 byte for alpha channel, 1 byte for red, 1 for green and 1 for blue.
.REG
A registration file used to communicate with a software publisher the user with the legal right to use the application.
RGB
Red, Green, Blue, the three primary colors which can be combined to create all of the other colors of the spectrum. A typical CRT-based monitor has a "gun" for each of these colors.
RIFF
The Raster Image File Format, desighed by Mark Zimmer of Fractal Software, and used by Letterset. This MacOS format supports Black and White (B&W), Grayscale, and Red-Green-Blue (RGB) single-image files. It provides options for 256, and 17 million colors, or 17 million colors plus alpha channel. It does not support CMY, CMYK, HVS, and VLT color schemes.
RMF
Rich Music file Format, created by Headspace, supports a pseudo-streaming playback-while-downloading from a Web page of audio and MIDI files.
RLE
Run-Length Encoded file format, used by CompuServe. A graphics data-format with compression, single-image documents may contain either 128 by 96 or 256 by 192 pixels. For DOS/Windows and MacOS systems. Filenames have an: .RLE extension. This format is similar to Window's BMP.
.RPT
SpDE's detailed design Info Report File.
RTF
Rich Text Format developed for Microsoft Word's documents. Filenames have an: .RTF extension.
RTV
One of two Digital Video Interleaved
(DVI) compression/decomp-ression (codec)
formats. RTV, which runs
on the Intel/IBM Action Media II board can display video in
a window of 259 (h) by 240 (v) pixels at 15 frames per
second (fps). Another term for symmetrical is bidirectional,
which means that it takes the same amount of time to
compress the video as to decompress it.
