REQUIREMENTS
A C128 or C128D running CP/M 3.0, ZP/M, ZCPR3 or compatible OS.
At least one 1541, 1541 compatible or better disk drive.
80 column monitor capable of 640 X 200 bit map displays.
Supports 16K VDC!
OVERVIEW
PCX'EM is the fastest VDC PCX image viewer for C128 CP/M! PCX
files are created with PC Paintbrush by ZSoft for DOS, Windows or
any other compatible software. Currently only 2 color (1 bit)
images are supported. If you try to view 16 or 256 color PCX files
then PCXVIEW displays an error message.
USING PCXEM.COM
Viewing a PCX file is quite simple. Just use the following calling
convention:
PCXEM {u:d:}filespec {color} {64k}
(u:d:) is the optional CP/M user and drive. (filespec) is the PCX
file to view. You must include the .PCX extension. (color) is the
VDC background color 0 through 15. If no value is specified then
black on a white background is used. The (64k) option sets the VDC
to 64K mode if the VDC is in 16K mode. PCXEM will work even faster
in 64K mode since the character sets do not have to be saved and
restored.
PCXEM PCXEM.PCX 5 64K
This example sets VDC 64K mode and views PCXEM.PCX on a light green
background. Remember the (64K) option only needs to be used once,
so subsequent uses will be ignored.
READ THIS!!!
It is IMPORTANT that you toggle off the disk status line with
[CONTROL] [RUN STOP] before viewing any images. The disk status
line is updated during disk I/O and writes to the VDC. This will
throw off the current VDC update address PCX'EM is using and barf
all over the image. You can toggle on the status line later if
needed.
HINTS ON CONVERTING PCX FILES FOR THE VDC
You can scale PCX images created on a IBM with EGA or VGA to look
right on the VDC in 640 X 200 mode. For 640 X 480 images decrease
(-) the length (Y axis) by 60%. This will result in images that
are 640 X 192. For 640 X 400 images decrease the length by 50%.
This will result in images that are 640 X 200. 640 X 200 CGA
images work fine without scaling. If the original image has more
than two colors then you will need to dither it to two colors.
PAYMENT
