Hello Francis,
I like your program a lot and did use it many times to convert pictures for the Acorn Atom. This means that I load a picture, display it in monochrome BBC mode with the right dither pattern and then take a printscreen shot. Then I convert the picture to Atom resolution.
Is it an option to add the Acorn Atom display modes?
Code:
Mode X Y Colours Memory
0 64 x 48 2 0.5 K
1a 64 x 64 4 1.0 K
1 128 x 64 2 1.0 K
2a 128 x 64 4 2.0 K
2 128 x 96 2 1.5 K
3a 128 x 96 4 3.0 K
3 128 x 192 2 3.0 K
4a 128 x 192 4 6.0 K
4 256 x 192 2 6.0 K
The Atom colour pallette is static and can not be changed:
Code:
Value: Colour: Grey scale:
0 Green Grey
1 Yellow White
2 Blue Black
3 Red Black
Addressing is straight forward, top left is $8000 and bytes are sequential from left to right and then 1 line done. In colour mode each pair of 2 bits displays a coloured pixel.
Greetings
Kees
