Enum Class MemoryFormat
- All Implemented Interfaces:
Enumeration,Serializable,Comparable<MemoryFormat>,Constable
@Generated("io.github.jwharm.JavaGI")
public enum MemoryFormat
extends Enum<MemoryFormat>
implements Enumeration
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).
