(With epson printer driver [Compatible with STAR printers])
 
 
This program lets you view macpaint graphic files on
commodore 64 plus save & print option. as you may or may not
know macpaint files are 576 (horizontal) by 720 (vertical)
dots. in comparison 64 screen is 320x200 dots. in this
program the 64 screen acts like a window to the larger mac
screen.
 
Load and run this program. at the prompt enter macpaint file
name (works with both prg and seq files). after loading, it
will switch to bit map mode and the 64 screen will be at the
top left corner relative to the mac screen. (when the
directory is being listed, pressing <space bar> pauses the
listing. press any key to resume listing.)
 
The following is an explanation of command keys available to
you:
 
1) Scrolling  the four cursor keys ,i.e., left, right, up
and down keys will scroll the picture in the respective
direction. the scrolling in horizontal direction is 8 dots
(1 byte) at a time.however, scrolling in the vertical
direction can be set to 1 or 8 lines at a time by pressing
"1" or "8" key, respectively. this is useful for "fine
tuning" for the save option explained below. the "r", "l",
"u" and "d" keys are for  "big jumps". when pressed they
move the screen to the right, left, top and bottom edge of
mac picture, respectively. the "c" key positions the 64
screen at the center of mac picture.
 
2) Color change  when the picture is first displayed the
colors are set to cyan & black.macpaint files are monochrome
and this choice of colors is usually good. but if you wish
you can change the color of fore/background using f1 and f3
function keys. pressing f5 inverts the picture. pressing f7
changes the border color.
 
3) Zoom  pressing the "z" key toggles on and off the zoom
feature. this is a crude zooming effect achieved by skipping
every other raster line. the resolution is somewhat reduced
but it will let you see more of the mac picture on the 64
screen and get a feel of what the whole  picture looks like.
all scrolling commands mentioned above are also functional
in the zoom mode. i recommend that you use 1 line scrolling
while in the zoom mode.
 
4) Save  you can save at any time whatever you have on the
64 screen as a normal doodle file. this is done by pressing
the "s" key and program will then prompt for a file name.
don't forget the "dd" prefix for the file name if you intend
to use it with the doodle program.
 
5) Print  although you can only see a small part of the mac
picture on your 64 screen, you can print the whole picture
out. the printer option is activated by pressing the "p"
key. the print routine is for epson fx-80 or compatible and
star printers. the print density can be selected at either
72 or 80 dpi (dots per inch). printing at 72 dpi density is
recommended for correctly proportioned output. also you have
a choice of printing the  positive or the negative image. to
abort printing at any time, just hold down a key until
printing stops.
 
6) End  while in bitmap display press <return>. you will be
prompted for 3 options: to load another mac file, to return
to  bitmap screen or to end the program.

There are two version of MACVIEW for the C64,
MACVIEW64.EPSON and MACVIEW64.1525. They both function
identically. The only difference in the two version lies in
the printer that they support. MACVIEW64.EPSON supports
EPSON and STAR and compatible printers. MACVIEW64.1525
supports the 1525 and MPS801 printers.
There is also a MACVIEW specifically for the C128. I can't
say very much about this verison since I don't have a C128
to test it on. However, my presumption is that it function
also most like the C64 version, but with a better graphics
resolution. So the above documention may still applies for
the C128 version......enjoy.
