KOALA PAD / ATARI ARTIST
PICTURE PRINTER
by
TED BURGER
This program is a result of becoming frustrated while printing pictures
from the Koala Pad system.
The program is written in Atari basic with many machine language
subroutines. Some of the ML routines are my own and some of them
came from other authors. At the moment I can't remember the sources.
If you see some of your code in here, Thanks.
The program supports several printers, at least Epson, Gemini, NEC,
and Prowriter. To modify it for a different printer is very simple.
You can add the printer name to the list around line 100, add the
first letter to the check in the same area. The lines between
800 and 900 are where the printer is set up. Add another 'IF' statement
with the proper graphics control characters to set up your printer.
OPERATION OF THE PROGRAM
The program will ask you for the 'picture disk', picture files must
end with the '.PIC' extender. The screen will display a list of the
files on the disk, up 38 files. You make your selection from the list.
The program will load the selected picture from the disk. The picture
will appear in color at first then switch to black and white. The
bottom of the screen will switch to text to prompt you. Below the
text block is another line of graphics, this shows the shade of gray
assigned to each of the four color registers. To change the gray shade
of one of the color registers, select which one 1-4. The prompt will
change and ask which shade you want. Black = 1 and white = 5. The
numbers 2,3,4 will give you different shades of gray in order between
black and white. This will allow you to set up the picture in shades
of gray on the display screen.
NOTE: if you set color 3 and 4 to the same shade, the text will
not be visible but things will still work.
When you get the picture set up the way you want it, a tap of the
'P' key will send it to the printer. The other choices you have
here are: 'M'enu will take you back to the list of the picture files,
'V'eiw will temporarily show you the entire graphics screen just in
case something important is hidden by the text block.
This is a case of 'WHAT YOU SEE IS WHAT YOU GET', the gray scales
from the screen will be duplicated on the printer.
