If the name is to appear in a single colour, then the following procedure should be
used.
Draw the graphic in colours 0 to 127 only. Then mark the upper left most point of
where the name is to appear in any colour above 128. Set colour 128 to the colour
you wish the name to appear in. Use the palette copying option when packing the
sequence.
If the position of the name is marked with a box of say colour 130, then this box
will appear on the final sequence in colour 2 (130-128). If this box is required to be
invisible, use the same colour as exists at that point, plus 128. If the picture is
complex at this point, use only one pixel, and use a colour which stands out. For
example, if the colour at the point which represents the upper left most point of
where the name is to be positioned is colour 7. Set this pixel to colour 135 (128+7),
and set colour 135 to a colour which stands out on the picture. This pixels position
is then clearly marked, but when displayed at the scorer, this pixel will be
converted to colour 7 (top bit set to 0), which is it's original colour, and will not
interfere with the graphic.
It is possible to display the name in different colours, depending upon the colour of
the graphic at that point. This is done by setting the colours in the range 128-255
manually, and NOT using the palette copying option when packing the sequence.
The colour of the name is determined by the colour of the graphic at the point of
display, plus 128. For example, a simple two colour graphic has colour 1 as red, 2
as blue. If colour 129 (1+128) is set to yellow, and 130 (2+128) to green, then the
name will appear in yellow over the red parts of the graphic, and green over the
blue parts.
Special effects such as transparent names can be achieved in a similar way to the
use of score grids as described above.
