MemoryFormat
Description:
[ CCode ( cprefix = "GDK_MEMORY_" , type_id = "gdk_memory_format_get_type ()" ) ]
public enum 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_MEMORY_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_FORMAT_ARGB32` is represented by different `GdkMemoryFormats` on
architectures with different endiannesses.
Its naming is modelled after VkFormat
for details).
