|

|
|
*
|
||
|
|
* `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](https://www.khronos.org/registry/vulkan/specs/1.0/html/vkspec.html#VkFormat)
|
||
|
|
* for details).
