- 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.
