The following details all changes made to PCX2EXE since version 1.12.
-----------------------------------------------------------------------------
12.10.93 Ver 1.44 : Improvement - optimised startup code & tweaked other
bits, saving 200-250 bytes on most stub files.
Improvement - The old STUB02 and STUB05 files have been
replaced by a single STUB02.EXE, which handles both
full and smaller than full screen 320 x 200 x 256 colour
files, and does it several times more quickly.
Change - the four fractal images previously included as
part of the SHOW demo have been replaced by files
SLIDE1.EXE, SLIDE2.EXE, and SLIDE3.EXE, to reduce the
size of the final archive by about 60K.
-----------------------------------------------------------------------------
7.10.93 Ver 1.43 : Bug fix - The palette routine for 800 x 600 images would
occasionally result in some distorted colours.
Bug fix - Fixed a STUPID bug which prevented PCX2EXE
converting a PCX file stored in a root directory ....
Improvement - PACKPCX now displays the file size both
before and after compression, and the percentage by
which the file size was reduced.
Improvement - P2E, SCALEPCX and PACKPCX now accept
wildcards in their command line arguments.
Improvement - P2E now checks to see that the file to
be converted really is a PCX file ....
Improvement - SCALEPCX has been completely re-written;
it's now much faster, and works on all the images the
other utilities can handle.
Change - All files now share the same date and time.
-----------------------------------------------------------------------------
29.9.93 Ver 1.42 : New file - STUB06.EXE displays 320 x 400 x 256 colour
images on any register-compatible VGA system.
New file - STUB07.EXE displays 360 x 480 x 256 colour
images on any register-compatible VGA system.
New file - STUB04.EXE now sets 800 x 600 x 16 colour
mode on most SVGA systems, without requiring VESA
compatibility ( as previously ).
New file - STUB04a.EXE is the old, VESA-only STUB04.EXE.
This is retained as it using it produces smaller
files.
Change - PCX2EXE.HLP, which only contained a subset
of the PCX2EXE.DOC file anyway, was removed.
-----------------------------------------------------------------------------
28.9.93 Ver 1.41 : Bug fix - CHVESA incorrectly displayed the minor
version number one place to the left, i.e. version
1.02 was displayed as 1.2.
Bug fix - PACKPCX was missing the first colour in the
palette, with strange results if it wasn't black ...
Bug fix - STUB03.EXE, the EGA 640x350x16 host file,
had been accidentally replaced with a version of the
VESA stub.
Improvement - STUB02.EXE is now optimised specifically
for full screen 256 colour files, and is more than twice
as fast as before.
New file - STUB05.EXE handles 256 colour files of other
than 320 x 200 resolution.
-----------------------------------------------------------------------------
24.9.93 Ver 1.40 : New file - PACKPCX.EXE, optimises 256 colour PCX files
of any resolution, can reduce file size by 20% plus.
The greatest gains are on complex scanned images using
lots of different colours.
P2E altered to call PACKPCX whenever it is asked to
compress a 256 colour file.
New file - ScalePCX.EXE reduces a 256 colour image of
up to 640 x 480 resolution to to 320 x 200, so that it
can be viewed on any VGA or MCGA monitor.
P2E altered to call ScalePCX when appropriate.
New file - AboutPCX.EXE displays information on any
PCX file.
New file - STUB04.EXE permits the display of 800 x 600
16 colour PCX files on VESA compatible systems.
New file - CHKVESA.EXE can be used to see if a system
is VESA compatible and can use STUB04 files.
Improvement/bug fix - STUB02.EXE, the 320 x 200 x 256
colour host file, now correctly displays files smaller
than full screen size. It's also optimized to be about
300 bytes smaller ( compressed size ) than before.
-----------------------------------------------------------------------------
16.9.93 Ver 1.31 : Optimisation - tweaked the stub file code, reduced size
when compressed by DIET by about 100 bytes.
Improvement - SHOW.EXE now has three new command line
switches, to make image display smoother.
/NOTEXT disables the return to text mode, /NOCLS
avoids clearing the screen between images, and
/NOBLANK avoids the screen blanking that normally
occurs when an image is displaying.
-----------------------------------------------------------------------------
14.9.93 Ver 1.30 : Improvement - New P2E and new stub files now permit any
size of PCX file to be turned into an EXE file. Eureka !
Modified PCX2EXE.DOC and PCX2EXE.HLP accordingly.
New file - FILELIST.DOC, lists every file in the PCX2EXE
package and gives a one-line description of its purpose.
-----------------------------------------------------------------------------
Ver 1.20 : New program - GET-PCX, a screen grabber that saves most
screen types into a PCX file. Additionally, saves a text
mode screen to disk ( optionally in a Basic-compatible
BLOAD format ).
New file - HISTORY.DOC.
-----------------------------------------------------------------------------
Ver 1.12 : Initial shareware version. No PCX files above about 60k
can be converted.
