IMPROVING PICTURE PRINTOUTS
I HAVE just a quick query but I'm sure it's one you will have heard be-
fore. To prevent having to sit in front of my computer reading screen-
fuls of text, I print out everything using the One Pass Text Printing
facility. What this doesn't do though is print out any diagrams or pic-
tures. There are sometimes quite a few of these I would like to have a
hard copy of - and I use a screen dump to dump them to my black and
white dot matrix printer.
The query I have concerns colours. Probably due to the screen dump I
am using, only pictures in Mode 0 and 4 print out perfectly. If I
attempt to print out, e.g. the Chicken and Fox opening screen on EUG
#52, the printout is rather 'bitty', i.e. like the screen itself if
loaded into Mode 0.
I suspect that it is the number of colours that causes the problem as
it only manifests when there are more than two colours on screen. VDU 19
commands don't have any effect, and obviously ruin the effect of
dazzling graphic displays.
Is there anyway of converting colourful screens to monochrome?
Alasdair Davis, Dumbarton
YES, there is. Obviously I can't guarantee to solve the problem as there
are so many different screen dump utilities and printers that it's hard
to know where to begin. However, it sounds like you may be able to get
around the problem perfectly by loading the screen into Mode 0 and then
restoring the original definition of Mode 1.
The code for doing this was published in EUG #19 and was originally
submitted to EUG by Alan Richardson, New Zealand. You will need to *LOAD
the code into memory, go into Mode 0, *LOAD the (Mode 1) picture you
wish to dump (It will look as you say, 'bitty') then CALL the machine
code twice to clean it up. Depending on where your screen dump utility
stores its own code, you may have to *SAVE the new picture before using
your screen dump with it. As you're using screen memory, this will re-
quire a short program.
You will then have a high-definition black and white Mode 0 image and
should be able to get a hard copy of it without trouble. You will
receive a free copy of EUG #19 with this issue and will note that the
demonstration picture on it is one of Kylie Minogue (digitised by Simon
Pilley).
