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.
