EPS
EPS stands for Encapsulated PostScript. Many page layout programs support
this format for images placed or imported into a layout file. Like TIFF files,
EPS files include information about the file’s characteristics that allows many
different kinds of computers to open and interpret the color and image data
in the file. For example, personal computers running MS-DOS and UNIX
workstations can open and use image files saved in the EPS file format on a
Macintosh. (PC-DOS and UNIX workstations can’t display an EPS file’s
Preview image, however.)
An EPS file usually includes a Preview image, which is the image that
appears on your Macintosh screen when the file is placed or imported into a
page layout document that supports EPS files. The preview is only a screen
image, usually of lower resolution than the main image. When you print the
page layout document, the real image prints.
The Preview image data is separate from the image data of the EPS file itself.
Because the Preview image is a separate part of the image file, PhotoFlash
allows you to define the characteristics of the Preview image independently
from those of the rest of the EPS file.
The options that can be applied to an image file saved in the EPS format
appear in the Save As EPS dialog box. You can also choose to apply JPEG
compression to the file, in which case the JPEG compression controls become
active. For more information about the JPEG controls, see “Using JPEG
Compression” later in this chapter.
