NAME EGSShow 1.1 - GIF, JPEG and IFF viewer for the EGS window system SYNOPSIS egsshow [file] STATUS AND COPYRIGHT This program is public domain. It may be distributed as long as the program and this manual file are always distributed together with the following copyright notice and are not modified in any way: EGSShow Copyright in 1994 by Dietmar Heidrich DESCRIPTION EGSshow is a viewing program for GIF, JPEG and IFF 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 as well as valid IFF ILBM files, including EHB, HAM6, HAM8 and IFF24. The format of the file is detected automatically. The display window's open size is determined by the initial picture 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. EGSShow needs a lot of memory for bigger pictures ( > 640 x 480) and EGS version 6 or higher. Selecting a lower colour depth than 24 bit for the EGS default screen will save you lots of memory. SHELL OPTIONS file The GIF, JPEG or IFF file to read at startup. If no file is initially 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: Open Opens file requester to display another picture. Picture info Displays info about the picture, ie. format, size and optional info. Keep size Checkmarked item that determines if the display window is resized for every newly loaded picture (default) or if its size is kept constant. About Displays copyright info. Quit Quits the program. TROUBLE GUIDE If no picture is displayed after loading, there is a number of reasons what might have gone wrong. First of all, you need enough memory. Then there are JPEG file formats that are not supported such as arithmetic encoding. The weird NewTek IFF24 format is not supported, only standard IFF24 is. CREDITS This software uses JPEG code from The Independant JPEG Group Version 4 and the GIF decoder written by Steven A. Bennett. IFF support by Dietmar Heidrich.
