- 1.0 Introduction
-
- VueSav is a Windows 3.1 screen saver that lets you view GIF,
- JPEG, and BMP graphics files when your system isn't busy. VueSav
- supports all graphics displays that operate with the MicroSoft Windows
- 3.1 operating environment, using a 386 or 486 microprocessor. VueSav
- displays graphics files on black/white or 16-color displays by using a
- technique called error dispersion dithering, and uses as many colors
- as are available on other Windows displays.
-
- The two key features of VueSav are speed and ease of use. VueSav
- is more than twice as fast as most other JPEG viewers, and is able to
- scale images to full-screen more than five times as fast as other
- viewers. VueSav will scale images to fill a window automatically,
- without distorting the image shape. VueSav also supports viewing GIF
- or JPEG images that can't completely fit into the available memory.
- It does this by storing a lower-resolution image in memory.
-
- Version 2.0 of VueSav fully supports displaying JPEG images on
- 16-bit or 24-bit displays, without lowering the image quality by
- dithering.
-
- 2.0 Prerequisites
-
- In order to use VueSav, you will need a personal computer that is
- running Microsoft Windows version 3.1 or higher. You will also need a
- 386 or 486 microprocessor. VueSav will work with any Windows display,
- including Hercules, EGA, 16-color, 256-color, 65536 color, and 24-bit
- color displays.
-
- VueSav is distributed via CompuServe as shareware, and may be
- evaluated for 15 days. If you decide you want to register VueSav,
- type "GO SWREG" and register program #1883.
-
- When you register VueSav, you'll receive assistance via e-mail
- with any problems you may encounter. You'll also receive a Serial
- Number identifying your copy of VueSav. This serial number is also
- valid for VuePrint - a very fast program for viewing and printing
- JPEG, GIF, and BMP files. VuePrint can be obtained separately from
- CompuServe, America Online, and various Internet and BBS sites
- (VUEPRI.ZIP).

- 3.0 Installing and Running VueSav
-
- To install VueSav, put the file VUESAV.SCR in your Windows
- directory - usually C:\WINDOWS. Then open (double-click) the Windows
- Program Manager's Main folder, and double-click the Control Panel
- item. After opening the Control Panel folder, double-click on the
- Desktop item to bring up the Desktop control panel. Select the
- "VueSav Screen Saver" item from the list of screen savers, and then
- select the Setup button to configure the VueSav Screen Saver. To test
- how it behaves, select the Test button.
-
- If you decide to register VueSav, you'll receive a serial number
- that you can enter after selecting the Setup button. You won't have
- to re-enter your serial number if you've already entered it when
- running VuePrint.
-
- The VueSav screen saver finds a list of graphics files starting
- in the directory you select in the Setup screen. It searches through
- all files and directories starting in the directory you specify. It
- will choose a maximum of 1024 files for display. If you check the
- Random item, the graphics files will be displayed in a random order,
- otherwise they will be sorted by filename. Only those file types that
- are checked will be added to the list of files to be displayed.
-
- 4.0 Bug Reports and Enhancement Requests
-
- If you have problems running VueSav, or have an idea for
- enhancing VueSav, please send e-mail to Ed Hamrick on CompuServe at
- 71470,3236. You can also send e-mail from the Internet to
- 71470.3236@compuserve.com.
-
- There's one problem that occurs when there isn't very much memory
- available. Large JPEG files are sometimes displayed as a grey screen.
- GIF and BMP files will display with reduced resolution in this case.
-
- VueSav doesn't yet read compressed BMP files or 24-bit BMP files.
