   Bitmap to PNG By 轮回者
==============================================================================

对Bitmap对象直接使用

bitmap_obj.make_png(name[, path])

name:保存文件名
path:保存路径

感谢66、夏娜、金圭子的提醒和帮助！

Instructions

Import any tileset into the Tilesets folder that you want merged together.
Then run the game and it'll merge it for you.
Make sure all the tilesets have the same background color.
Merged tilesets will appear in the root of the game folder.

Compatibility

Should work with anything
Not tested with SDK
