Transparent PNG data to X68k sprite data converter
pip install git+https://github.com/tantanGH/png2sp.git
png2sp [options] <input-png-file>
Input PNG file can be RGB PNG or RGBA transparent PNG either.
options:
-o [output-file] ... 出力先テキストファイル名 指定しない場合は標準出力
-b ... X-BASIC ライクな 1ドットごとの unsigned char 配列として出力 (default:False)
-x [width] ... 横サイズ 16の倍数であること
-y [height] ... 縦サイズ 16の倍数であること
-a ... 256x256,512x512などの横長ピクセルでの利用を想定し、元画像を一旦2:3の縦長にしてから処理 (default:False)
-d ... スプライトパターンではなく 65536色で GVRAM に直接描くビットマップ配列として出力

ドットを微調整したい場合などはこちらが便利です。ただしPCG定義を行う際に変換が必要です。
