Graphics Interpreter

*******************************
The
graphics interpreter offers you a facility to define your own char-
acter set.
Using the
"TEXT"
instruction, you can write any desired text
on the screen which may contain your own characters. The "FILL
11
instruc-
tion
which
fills specified areas with some pattern also makes
use
of
this character table , so that you can create your own fill patterns.
Each character must be regarded as a matrix of
8
times
8
bits. The "IMG
11
instruction lets you define up to
8
bytes of
8
bits each for a character
matrix.
For example,
let's see what the matrix of the letter
"A
11
looks
like:
Byte
l
00011000
18H
* *
Byte 2
00100100
24H
*
*
Byte
3
01000010
42H
*
*
Byte 4
01111110
7EH
* * *
* * *
Byte
5
01000010
42H
*
*
Byte
6
01000010
42H
*
*
Byte 7
01000010
42H
*
*
Byte 8
00'00'0'0'00
00H
Another kind of pattern can be used to fill areas:
Byte
l
10'00'10\Hi,
88H
*
*
Byte 2
0100'0100
44H
*
*
Byte
3
0'0100010
22H
*
*
Byte 4
1!10'0HHHH
llH
*
*
Byte
5
l000HHHiJ
88H
*
*
Byte
6
0'1000100
44H
*
*
Byte 7
0'0100010
22H
*
*
Byte 8
00010001
llH
*
*
When executing
a
11
FILL" instruction using this image,
the area affected
will be hatched.
