What is QPEG386? ~~~~~~~~~~~~~~~~ QPEG386 (Quick-jPEG, pronounce "Q-Peg-386" [kju:peg]) is a viewer for JPEG image files. It is about twice as fast as other common JPEG viewers. Compare it yourself, you'll be surprised. JPEG (Joint Photographic Experts Group, pronounce "Jay-Peg") is an image file format which uses a "lossy" compression. JPEG images (they have usually a "JPG" file extension) are normally very small and offer better compression than any other image format. Decoding of JPEG images is a rather complicated process, thus it needs a lot of computing power and performance. QPEG386 takes advantage of the advanced features of 80386, 80486 and Pentium (586) CPUs, and it uses large look-up tables instead of formulas. Well, I don't want to get into details. It's fast, that's all you could want to know. Features ~~~~~~~~ - It's fast (have I mentioned that before?). - Uses advanced features of 80386/486 processors (note, the Cyrix 486DLC is only an improved 386 rather than a 486). - Nice preview ability which is even faster (lets you quickly browse through lots of images, very useful if you're searching for a certain image). - Works even with a standard VGA card (320x200x16, 640x480x16, 320x200x256). - Supports many SVGA cards (virtually all with VESA capability). - Uses truecolor (16M color), hicolor (32K color), 256 color (either greyscale or dithered color), and 16 color (dithered greyscale) modes. - You can pan across an image which is bigger than the current screen resolution (scrolling). Some XMS and/or EMS memory is needed for this. You can even pan using your mouse, which is much fun (at least on fast local bus machines). - You can change the resolution without loading/decoding the image again (this is restricted to the same color resolution, for example you can't switch from hicolor to truecolor without reloading the image). - Supports also the following image file formats (more to come): * GIF: + interlaced and non-interlaced + GIF87a and GIF89a (87a subset only) + displays the first image of a multi-image GIF * Targa (TGA): + truecolor (15, 16, 24 and 32 bit), greyscaled, or with palette + uncompressed or rle compressed (run length encoded) + supports all video modes (16, 256, 32K, 64K, 16M) * PCX: + 1 and 4 bit with standard palette + 8 bit with extended palette + 24 bit truecolor * BMP (Windows) + 1 bit monochrome with palette, uncompressed + 4 and 8 bit with palette, uncompressed or RLE4/8 compressed + 24 bit truecolor, uncompressed * BMP (OS/2) + 1, 4 and 8 bit with palette, uncompressed + 24 bit truecolor, uncompressed + also supports the new multi image format (BA-BMP) * IFF/ILBM (LBM) + 1 to 8 bit with palette, and 24 bit truecolor, also DP2 enhanced + uncompressed or compressed (ByteRun-1) + no HAM yet (due to lack of test images) Requirements ~~~~~~~~~~~~ - 80386 or better CPU (33 MHz minimum recommended), 386SX is sufficient - VGA graphics card (SuperVGA recommended, though QPEG386 will run on any standard VGA card) - some XMS and/or EMS memory (depending on the size of the images), though QPEG386 will also run without any XMS/EMS, but then you will be unable to do any panning/scrolling - about 500 to 550 Kb of free conventional memory - MS-DOS 5.0 or compatible operating system A mouse is not required, but it's much more fun than keyboard control! A numeric coprocessor is not required. If present, it will not be used, because it would not speed up decoding/displaying.
