This is a list of changes from previous versions. If you're new to QPEG,
please read QPEG.DOC.
Versions prior to 0.5b were beta versions, released only to a small number
of people.
QPEG 0.5b
~~~~~~~~~
First official release. I still call it beta, since some drivers are
not tested and may not work.
QPEG 1.0c
~~~~~~~~~
* No beta version, but not a final release either. I guess there will
never be a "final" release.
* Added support for Yh1v1 upsampled color images. Suggested by Tom Lane
(IJG). QPEG should now be able to view any JFIF compliant JPEG file,
and even some non-JFIF files.
* Switching back to text mode on exit now restores the same mode that was
used before starting QPEG. Suggested by Lutz Kotoll.
* Added GIF support. Suggested by thousands of users :-)
* Added TBH logo. Suggested by me :-)
* Added ability to delete and copy files. Also suggested by many users.
* If the preview's height is smaller than 61 pixels, its size is doubled.
In other words, pictures with an original height of more than 480 are
scaled down by a factor of 8, otherwise by a factor of 4.
* The executable (QPEG.EXE) is smaller.
* Added ability to switch greyscaled display on/off ('$' key).
* Added dithering routines for hicolor modes. Now hicolor looks
almost like truecolor.
* Added initialization file (QPEG.INI) for user changeable defaults:
- video mode
- file information on/off
- preview on/off
- beeps on/off
- hicolor dithering on/off
- greyscaled display on/off
Most of these settings can be changed within QPEG.
* Fixed problems when viewing greyscaled images in hicolor or truecolor
modes.
* Fixed preview code which caused errors on some VGAs. The preview
should now work on _ANY_ VGA graphics card.
* Changed ATI driver. I'm not sure if it's fixed, since I can't test it.
* Fixed VESA driver.
* New driver for DELL S3 graphics cards. Thanks to Lenny Lim!
(If it doesn't work, try the VESA driver.)
QPEG 1.0d
~~~~~~~~~
* QPEG now works with the VESA driver (both needed to be fixed).
* Changed the ATI driver (once again).
* English and German documentation.
QPEG 1.0e
~~~~~~~~~
* Driver for Diamond SpeedStar 24X. Thanks to Jan van Loenen!
* Driver for NCR 77C22 chipset. Thanks to Peter van Sebille!
* The executable (QPEG.EXE) is considerably smaller.
QPEG 1.0f
~~~~~~~~~
* Doesn't lock up anymore on corrupt JPEG files.
* Slightly improved accuracy (this fixes a bug that caused a checkerboard
texture on extremely bright areas).
* Supports interlaced GIF files.
* Supports Adobe Photoshop JPEG file format (non-JFIF).
QPEG 1.1c
~~~~~~~~~
* Changed directory structure:
directory ENGLISH for English documentation, directory DEUTSCH
for German documentation.
* QPEG FAQ.
* Fixed NCR configuration.
QPEG 1.2d
~~~~~~~~~
* Changed registration system.
* Changed status window. Press F1 for help.
* Fixed bug (blank screen when zooming very fast).
* Fixed bug in Cirrus driver file for 1280x1024x16 mode.
Thanks to Ben Jos Walbeehm!
* Driver for Realtek chipset. Thanks to Christopher L. Tumber!
* Supports 64K hicolor modes (16 bit) using 65536 colors.
* Option for automatic video mode selection (depending on the image size),
see QPEG.INI for details.
QPEG 1.2e
~~~~~~~~~
* Fixed bug (white areas occured when decoding high quality JPEG images).
* Fixed bug (QPEG didn't recognize write protected GIF files, for example
on CD ROMs).
* You can select images with the space key (tagging), then use shift+enter
to view the selected images only.
QPEG 1.2f
~~~~~~~~~
* Tagging bug fixed.
* Targa files are recognized (but not displayed yet).
* Truecolor modes (16M) work now with Diamond Viper and VESATRUE.CFG.
* Various bugs in the documentation fixed.
* There's a QPEG support BBS for fidonet and modem, see QPEG.DOC.
QPEG 1.3b
~~~~~~~~~
* Displays Targa (TGA) files! It supports:
- truecolor TGA, greyscaled/monochrome TGA and TGA with palette,
- uncompressed TGA and rle (run length encoded) compressed TGA,
- any TGA type can be displayed in any video mode (just like JPEGs),
- TGA display is F A S T !
* Increased maximum number of video modes from 25 to 40.
* Total rewrite of the general graphics routines, adding new formats
(PCX, BMP, PBM/PNM etc) is now much easier.
* Mouse support! Your mouse driver must be Microsoft compatible.
If you have a Genius mouse driver, it should be at least version 9.06,
otherwise you'll have to disable mouse support (see QPEG.INI).
* Supports up to three mouse buttons.
* Freely configurable mouse buttons: the mouse buttons can be programmed
to do anything which can be done with the keyboard. See QPEG.INI.
* Changed AUTO_MODE options in QPEG.INI.
* The video driver (*.DRV) needn't be copied to the QPEG directory
anymore.
* Fixed truecolor mode with Diamond Viper (once again).
* Fixed another truecolor bug (VESA configuration) which caused previously
displayed images not to be cleared correctly.
* Now you can specify a drive or directory on the command line, and qpeg
will start up in that directory.
* QPEG gives the following error levels for command line viewing:
- 0 : ok (no error),
- 5 : at least one file is no valid graphics file,
- 20 : fatal error, e.g. unknown command line option, error in
configuration file etc.
Those error levels can be used for batch file processing.
* You can use Shift+Del to delete all tagged files at once.
* You can use Shift+Inst to copy all tagged files at once.
* Another ATI driver (ATI-3.DRV) for ATI VGA Wonder 18800.
Thanks to Yaron Keren!
* Fixed several bugs.
Coming soon:
Better tagging, slideshow, file masks, changeable file sort order,
fit-to-screen for large images, support for 4DOS/NDOS descriptions,
and more.
