MINI MINIPAINT TUTORIAL
*************************************
Created by Michael Kircher
As a comprehensive manual for
MINIPAINT is in the works, a
complete coverage of the editing
functions is given there. For the
following tutorial it suffices to
know, that cursor controls work as
usual, pixels are set with the keys
1 to 4, their colour assignment is
changed with CTRL-1 .. CTRL-4, SPACE
toggles between editor, and a full
screen preview, and while editing it
is always possible to invoke the on-
line help system with '?' (SHIFT+ /).
MINIPAINT requires at least a +16K
RAM extension.
When you draw a picture in
MINIPAINT, at first you need to
think about, which colours appear
most often in the scene. For an
example, consider a single apple
tree against the sky, with the sun,
some clouds, and a few birds.
The three most common colours are
Light Blue for the sky, Green for
grass, and leaves, and Brown for the
branches and trunk of the tree -
where the darker version of Orange
is the best approximation for. One
of these three colours must be
chosen from the lower 8 available
colours, because it is assigned the
border colour. In this case, there
is only one choice, Green.
In case you do not want a visible
border appearing around the scene,
you might:
- choose background, and border
colour the same,
- in high resolution mode, set
foreground the same as border
colour, fill with foreground, and
draw the scene as negative image in
background colour. Even though this
normally restricts the picture to
two colours, the paint colour now
can be any one of the 16 available
colours, or
- in a similar fashion, in
multi-colour mode, fill the picture
with pixels in border colour
beforehand.
Press 'M' to show the full palette
display in the status window. Then
change background (1) to Light Blue,
border (3) to Green, and auxiliary
colour (4) to Orange. The foreground
colour (2) is used to draw
everything else, for the moment you
should set it to Black. Press CLR
(with SHIFT) to clear the screen.
Orange is toned down to Brown for
the branches, and trunk of the tree.
For this, mix Orange, and Black in
the top-left corner of the screen in
a chequered pattern, up to X=6 and
Y=15 - the whole top-left attribute
cell. Cut the cell with the DEL key,
and then sketch the bottom ground,
and tree with the INST key:

Refine the details by clearing
pixels to background colour, and
adding pixels in Black or Orange
fitting to the pattern. Sketch the
outline of the treetop in Green:

The grass at the bottom is painted
in two steps: first put a two-pixel
thick line in green between ground,
and sky. Then add blades of grass
with vertical lines. To draw the
apples, change the foreground colour
(2) to Red. Place the apples within
the treetop. While doing this, some
parts of the branches might change
colour from Black to Red. This is
the colour clashing mentioned in
chapter 2. Leave the affected parts
alone for the moment.

When you have placed all apples,
take a look, where the branches have
changed from Black to Red. There,
replace the Red colour with Green.
Since that colour is taken from the
border colour (3) this does not
incur yet another colour clash - and
later will 'hide', that a colour
clash had happened in those places.
Then, within the outline of the
treetop, apply another chequered
pattern of Green over the
background, so the Green pixels are
aligned with those used to conceal
the colour clashes. This step
completes the tree.

To draw the sun, change the
foreground colour (2) to Yellow, and
press 'H' to switch to high
resolution mode. Place the sun in
the top-left quarter of the picture.
Draw the outline first, then fill
the interior. Then, add some clouds.
Change the foreground colour to
White, and place the clouds in good
distance to both sun, and tree to
avoid colour clashes. Add some
structure along the top- left facing
part of the clouds by clearing
pixels to background colour. For the
finishing touch, change the
foreground colour back to Black
again, and add some birds - the
picture below to the right-hand side
shows the result:
