Load image from EEPROM
Displays the image saved in the EEPROM with the number

.
Example: $1B

Upload image
Displays an image at position
x1,y1
.
data..:
- 1 byte for the image width in pixels
- 1 byte for the image height in pixels
- Image data: number = ((7) / 8) * width bytes
1 byte stands for 8 horizontal pixels on the screen; 0=white, 1=black;
LSB: top, MSB: bottom; the image is stored from left to right.
The BMP2BLV.EXE program on the EA DISK240 floppy disk available as an
accessory creates the image data, including the width and height, from monochrome
Windows bitmap graphics (*.BMP).
Example:
$1B $55 $4C $09 $04 $0C $0C
$F0 $FC $FE $FE $F7 $BF $BF $F7 $FE $FE $FC $F0
$00 $03 $07 $06 $0D $0D $0D $0D $06 $07 $03 $00
Loads the adjacent image at position 9,4.

n1
Set graphics mode
Sets the link mode
n1
for the following graphics functions: ESC P (Set point), ESC G (Draw straight line), ESC W
(Continue straight line), ESC R R (Draw rectangle), ESC R N (Draw rounded rectangle), ESC R M (Fill area with
pattern).
Example: $1B
$56 $03
Sets the link mode to inverse.
By way of example, a rectangle is drawn alongside with
the link modes set, delete and inverse on an existing
background.
Link mode n1:
1 = set: black pixels irrespective of the previous value (OR)
2 = delete: white pixels irrespective of the previous value
3 = inverse: changes black pixels to white pixels and vice versa (EXOR)
4 = replace: deletes the background and sets black dots;only area with fill pattern 'pat'
5 = inverse replace: fills the background and sets white pixels; only area with fill
pattern 'pat'
ESC

Continue straight line
Continues a straight line from the last end or point drawn to
x1,y1
taking into account
the set graphics mode 'V'.
