Summary
Submitted by algorithm on 11 January 2010
This converter converts a truecolor Jpeg/Bitmap picture to three seperate
c64 hires bitmaps which when flicked together fuse the colors together to
create a rendition of the original image
The routine works by analysing each 8x8truecolor block and feeds every
combination of ink/paper through the 3 bitmap layers.
It then generates 8 mix colors for each combination and removes any
combination which would cause too much 'flicker'
The 'best' color combo is selected for the block and repeated until the
entire image is converted
The flicker is reduced immensely by interleaving the bitmaps while displaying
them. This requires the c64 code to force a badline each line (as FLI)
Displaying three screens to form one image even when using interleaving methods
will look horrible unless viewing it on a real c64 and tv screen
Viewing it on anything with unstable framerate will break up the image immensely
and the illusion of more colors will be destroyed
Due to the bruteforce routine looking at all color combinations, it takes a very
long time to process the image. (On my dual core machine at 2.8ghz, it takes
around 10-15 minutes
his GFX mode is merely three standard c64 bitmaps flicked together.
Immense improvements can be made if using FLI as this would allow 8 mix
colors per 8x2 block instead of 8x8
Flickering can be reduced further by evening pixels to other layers where
the colors in a specific layer(s) are the same
