Chapter 7
GIF (Graphic Interchange Format) is another file format widely used on the Internet
GIF File Types
World Wide Web. This format is best used for simple graphics created by illustration pro-
grams. GIF compresses areas of flat color quite well. The format supports only 256 colors,
so it is not particularly suited for photographic images or complex graphics that use a
high degree of shading and color variations.
PowerScript supports interlacing of GIF images, but does not support transparency.
When you require transparency, use the EPS file format and clipping paths, or CMYA
channels.
PCX is a file format commonly supported by several different Windows and DOS
PCX File Types
paint-type applications.
PowerScript-Provided Graphics
PowerScript comes with an assortment of graphic files provided by Videonics (see
page 203). You can find these files on the original PowerScript Start Card. You can remove
the files from the Start Card if you ever decide you don't need them any longer.
About Other Graphics
You can use graphic files from many different sources, such as existing clip art collec-
tions, the Internet, or your own archives. You can also create custom graphics if you have
the necessary tools (this section discusses tools and techniques for creating graphics).
You can convert other graphic file formats to the formats supported by PowerScript if you
have the necessary tools. Some conversion tools are available at our Videonics Web site.
See Table 1, Contacting Videonics, on page 2 for the location of this site.

WARNING!
If you remove a graphic file from the original Start Card there is no way to
get that graphic back again. If you think you might want to use the graphic
at some later date, place a copy of the file on another PC Card or on a com-
puter-based hard disk. To do this procedure you must have a connection
between PowerScript and another computer. See Chapter 8, PowerScript Com-
puter Connections, for instructions.
Note
Software applications can create graphic files that neither PowerScript nor any other
device can process and display. In most cases, if you can output the file to a printer,
PowerScript can also process it. Large, highly-complex graphic files take extra time to
process—both by PowerScript and by laser printers. Although PowerScript operates
significantly faster than a printer, such delays might not be acceptable in a video pro-
duction environment.
