png2tiles.py
This is a new version of png2tiles.py that changes functionality considerably when
compared to the ubox MSX lib version.
Introduced --preferred-bg and --preferred-fg options with the following rules:
-
If a 8x1 block (8 pixels aligned) contains color X,
--preferred-fg Xwill set X as the MSN (most significant nibble) in the respective colour byte, which is the foreground colour position. -
If a 8x1 block (8 pixels aligned) contains color X,
--preferred-bg Xwill set X as the LSN (least significant nibble) in the respective colour byte, which is the background colour position. -
if the 8x1 block has a single colour (white for instance),
--preferred-bg Xwill set the background to X, which means that pixels/colours of the block are now0xff/0xfX. And in case of--preferred-bg 15, pixels/colours values of the block are now0x00/0xYf(where Y is defined by--preferred-fg Yor defaults to 1). -
if the 8x1 block has a single colour (white for instance),
--preferred-fg Xwill set the foreground to X, which means that pixels/colours of the block are now0x00/0xXf. And in case of--preferred-fg 15, pixels/colours values of the block are now0xff/0xfY(where Y is defined by--preferred-bg Yor defaults to 1). -
--preferred-bg Xhas precedence over--preferred-fg Y, so in a Z-coloured 8x1 block, pixels/colour of the block are set to0xff/0xZXinstead of0x00/0xYZ.
