Technical details about BMP and PNG formats
Microsoft Windows bitmap
By default the BMP format is version 4. Use BMP3 and BMP2 to write versions 3 and 2 respectively. Use -define bmp:ignore-filesize to ignore the filesize check.
Portable Network Graphics
Requires libpng-1.0.11 or later, libpng-1.2.5 or later recommended. The PNG specification does not support pixels-per-inch units, only pixels-per-centimeter. To avoid reading a particular associated image profile, use -define profile:skip=name (e.g. profile:skip=ICC).
