Rangi 004749ea75 Halt processing when any ambiguous-transparency colors exist (#2093) 2026-09-16 04:03:56 +02:00
Rangi 7746ddbf2b Fix reverse-graphics check for whether the tilemap references too-high tile IDs in bank 1 (#2086) 2026-09-14 10:26:57 -04:00
Rangi f8a1da71c1 Only sort generated palette colors by PLTE order for indexed PNG images 
Non-indexed images can still have a PLTE chunk. We should use
`sortRgb` instead of `sortIndexed` for them, since their pixels' colors
may not all be present in the PLTE chunk and would be unsortable.

Rangi 3b33c942ae Fix a crash and a limitation in RGBGFX unoptimized output 
- If both banks 0 and 1 were completely filled, then
  `assume(bank == 0)` would false and potentially crash.
- If the input image had fully-background tiles, they would be
  incorrectly counted towards `nbTiles` and could cause the
  "Image contains N tiles, exceeding the limit" check to fail.

  (a comment implied we were already doing this, but we weren't)
- Add more verbose logging to debug this behavior
