Enumeration

GdkMemoryFormat

Declaration

enum Gdk.MemoryFormat

Description [src]

GdkMemoryFormat describes a format that bytes 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).
