png2prg 1.8

PNG2PRG 1.8 by burg

Png2prg converts a 320x200 image (png/gif/jpeg) to a c64 hires or
multicolor bitmap, charset, petscii, ecm or sprites prg. It will find the best
matching palette and background/bitpair-colors automatically, no need to modify
your source images or configure a palette.

Vice screenshots with default borders (384x272) are automatically cropped.
Vice's main screen offset is at x=32, y=35.
Images in sprite dimensions will be converted to sprites.

The resulting .prg includes the 2-byte start address and optional displayer.
The displayers can optionally play a .sid tune.

This tool can be used in all buildchains on all common platforms.

What is new

Png2prg 1.8 introduces multiple image optimization techniques to improve
the pack ratio of output images.
See 'Brute Force Mode and Pack Optimization' below.

Multicolor charsets of multiple frames is now supported.
See testdata/charanim for an example.

png2prg 1.6

Png2prg converts a 320x200 image (png/gif/jpeg) to a c64 hires or
multicolor bitmap, charset, petscii, ecm or sprites prg. It will find the best
matching palette and background/bitpair-colors automatically, no need to modify
your source images or configure a palette.

Changes for version 1.6

• Added -mode mixedcharset for mixed multicolor/singlecolor and
  individual d800 colors per char.
• Modified -mode sccharset to use individual d800 colors per char.
• Added -mode petscii.
• Added -mode ecm.
• Added -no-pack-empty to skip packing empty chars to filled chars to re-use
  for different colors. Only for mixed and ecm charsets.
• Added -force-pack-empty for singlecolor and multicolor charset, may save
  a char, but usually pack-ratio is worse due to increased d800 color usage.
• Improved auto-detection of graphics modes, including various charset modes.
• Added sid support to charset displayers.
• Added fullscreen fade in/out to charset displayers.
• Bug Fix: -force-border-color for singlecolor charset (thanks Raistlin).
• Bug Fix: do not write empty .prg file on error.
• Standardized d02x colors in output.prg for charset modes.

png2prg 1.4

png2prg 1.4

Png2prg converts a 320x200 image (png/gif/jpeg) to a c64 hires or multicolor bitmap, charset or sprites.
Now also supporting multicolor interlace, among various other fixes.

Changes for version 1.4

• Support for even more far-out palette ranges (thanks Perplex).
• Now throws an error if the palette can't be detected properly, this should
  never happen. Please let me know if you run into this error.
• Separated library and cli tool.
• Library supports the standard io.Reader and io.Writer interfaces.
• Patched TSCrunch further to increase crunch speed and use less memory.
• Added -parallel and -worker flags to treat each input file as standalone
  and convert all files in parallel. Gifs with multiple frames are still
  treated as animations.
• Stop relying on .gif filename extension, detect it.
• Add -alt-offset flag to force screenshot offset 32, 36), used by a few
  graphicians. Though, please switch to the correct 32, 35.
• Add -symbols flag to write symbols to a .sym file.
• Interlace support for mcibitmap (drazlace and truepaint).
• Bugfix: allow blank images input (thanks Spider-J).
• Allow colors not present in the image as -bitpair-colors (thanks Map).
