| NFormats33 | The number of formats. This value will change as more formats get added, so do not rely on its concrete integer. |
gdk.types.MemoryFormat describes formats that image data can have in memory.
It describes formats by listing the contents of the memory passed to it. So gdk.types.MemoryFormat.A8r8g8b8 will be 1 byte (8 bits) of alpha, followed by a byte each of red, green and blue. It is not endian-dependent, so cairo.types.Format.Argb32 is represented by different GdkMemoryFormats on architectures with different endiannesses.
Its naming is modelled after VkFormat
for details).
