SYNOPSIS

DESCRIPTION
EGSShow is a viewing program for GIF and JPEG files on the EGS window
system. This program is able to read the JPEG format as well as the GIF
formats GIF87a, GIF89a and all future GIF files compatible with both of
the above. The format of the file is detected automatically.
The display window's open size is determined by the initial GIF or JPEG
file and the maximum possible size on the EGS default screen. The picture
itself is displayed in a scrolling gadget that lets you select the part
you want to see.
While reading the files, some status information about the picture is
printed onto stdout.
EGSShow needs a lot of memory for bigger pictures ( > 640 x 480) and EGS
version 6 or higher.
SHELL OPTIONS
file

specified, no picture is displayed first.
WORKBENCH
EGSShow can also be started from the workbench. To initially display a
file, first click on the picture icon and double-click the EGSShow icon
while simultaneously pressing the shift key.
MENUS
EGSShow has only one menu named "Project" which contains the following
items:
