Plus/4 hires & multicolor bitmap support
As the title says: plus/4 specific image format support is missing. It has 16 colors each of 8 brightness levels. Its bitmap format is the same as C64 (320x200, 8 bytes per char), only color layout & restrictions per char and multicolor bit pair meaning are different. Image types: multicolor bitmap, hires bitmap. hires bitmap extra functions: Import Botticelli, Export Botticelli multi bitmap extra functions: Import Multi Botticelli, Export Multi Botticelli I can provide the RGB palette and the exact specification of color memory layout, etc. here later if needed.
Ok back again! I searched the web but seem to be unable to find any helpful information..
so. What are the cell restrictions? if the format is the same (320x200 in 1 bitplane), then how do you differentiate the colors?
Like, how do you even set bitmap multicolor mode? I'm unable to find any info online, almost..
You can download a very detailed description of registers, ram/rom layout, etc of the plus/4 machines from here. To turn on bitmap mode: lda $ff06 ora #$20 sta $ff06 To turn on multicolor mode: lda $ff07 ora #$10 sta $ff07
I'll close this one since I haven't been able to find any info online.. if you're still interested in getting plus/4 multicolor images into TRSE, I'll need some more detailed answers on how to implement the image class!
