GdkMemoryFormat
since: 4.0
Description [src]
GdkMemoryFormat
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).
