I call it a bmp-to-text.c program ~

Gcc-o b2t bmp-to-text.c-finput-charset = gbk-mwindows

Convert BMP monochrome bitmap into text...

For example, if you create a bitmap and draw a cloud word on the in-place graph, the following results can be produced:

Cloud cloud

That is, it's okay to have fun ~
