The Encapsulated PostScript file (EPS) format is supported by most illustration and page
layout programs, and in most cases is the preferred format for these applications.
Note that this is also the only file format that supports transparent whites in Bitmap mode.
Raw
The Raw format is a flexible file format for transferring documents between different
applications and computer platforms.
Raw format consists of a stream of bytes describing the color information in the file.
Each pixel is described in binary format, where 0 equals black and 255 equals white.
Scitex CT (Scitex Continuous Tone)
The Scitex CT format is available for CMYK color images and grayscale images.
Scitex computers are used for high-end image processing.
CUT
CUT file format is definitely the most awkward format.
CUT files do not "know" how many colors they have in them.
They rely on a second accompanying file, called a PAL file, to define their colors.
Most applications will search for the PAL file in order to determine whether the
CUT file has two or eight bits of color. If there is no PAL file with the same name as
the CUT file, the CUT file is treated as 2 colors. Files saved to the CUT format from
various applications will appear as two color files if they were recognized that way or
as 256-color files if they had more than two colors initially. Note that a 256 color file,
with a missing PAL file will eventually end up as a 2 color file.
Characteristics:
CUT - witholi>CUT - without a PAL file supports 1 bit per pixel.
CUT - with a PAL file supports 1, 8 bits per pixel.
