Details The gdk:memory-format enumeration describes a format that bytes can
have in memory.
It describes formats by listing the contents of the memory passed to it. So :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 the :argb32 value of the cairo:format-t enumeration is represented by different gdk:memory-format values on architectures with different endiannesses.
Its naming is modelled after VkFormat. See
https://www.khronos.org/registry/vulkan/specs/1.0/html/vkspec.htmlVkFormat
for details. |
