ALLPAPER.EXE (VERSION 1.0) Copyright (c) 1994, Jeff Prosise ------------------------------------------------------------------------- First Published in PC Magazine September 13, 1994 (Utilities) ------------------------------------------------------------------------- ALLPAPER by Jeff Prosise PURPOSE: The Windows wallpaper feature does not have a facility for adjusting the size of bitmaps. Wallpaper is either centered on the screen or tiled. AllPaper lets you stretch or shrink a bitmapped image so that one copy of the image fills the screen. SETUP: AllPaper is extremely simple to use. You select a .BMP file, select an output resolution, and then click the Shrink/Expand button to create a new version of the image under the filename of your choice. Once you have the new .BMP file, you need only copy it to your Windows directory to make it available to the Control Panel's Desktop applet, where wallpaper settings are selected. REMARKS: AllPaper works with almost any .BMP file, including OS/2-style .BMP files, but there are some exceptions. It doesn't work with the 16-bit and 32-bit .BMP files used by Microsoft Windows NT, and it doesn't work with compressed .BMP files, which can be very difficult to deal with when bypassing GDI (Graphics Device Interface) functions as AllPaper does. If you attempt to input a compressed .BMP file, AllPaper displays the message, "Unsupported file format (DIB is compressed)." DIB stands for device-independent bitmap, the data format that lies at the heart of every .BMP file. On-line services such as CompuServe and ZiffNet are loaded with bitmapped images that can be used as wallpaper. With AllPaper, you can download the image of your choice without worrying about its resolution. If the bitmap is the wrong size, AllPaper can fix it for you. If you download a bitmap that is in compressed .BMP format, however, you will need a different utility to convert it to an uncompressed .BMP file. AllPaper does not support conversion between different graphics file formats. ------------------------------------------------------------------------ Jeff Prosise writes our Tutor column and is a contributing editor of PC Magazine.
