=== idea ===

• 2018 or 2017 breakpoint/revision
• C64-X-Party 2018 erster code

=== screen === 320x200 = 40 x 25 chars = 1000 bytes (vermutlich aber mit weniger bits moeglich)

=== titten+links kommen hier hin ===

=== overview === use a fixed set of chars and convert an animation to it. with simple compression we should make it to 80.000 bytes = 80 frames = 3.5 secs.

=== steps ===

• choose a frame and strip it to 320 x 200 monochrome.

  • convert image.jpg +dither -colors 1 -depth 1 image-mono.png && cp image-mono.png big.png
  • convert big.png -crop 8x8 parts-%03d.png

• generate x,y.png with 8x8

• have also all petscii chars in a raw format 8x8 -> png

  • convert big.png -crop 8x8 parts-%03d.png

• loop {

  • choose a "random" set?
  • construct new image from random set:
    • for x in 1...40; do for y in 1...25; do compare dithered with all petscii-chars and get score ->dssim|butteraugli remember to best 3(?) chars or choose a random out of 5 best? done done
  • compare to whole dithered picture with all variations from above 40*25 !5 = ???
  • re-construct full picture
  • start (dssim + butteraugli) and get score for all permutations }
