◆ vk_format_bytes_per_pixel()
|
inline |
Byte width of a single pixel for a given Vulkan format.
Covers all formats currently tracked in GraphicsSurfaceInfo plus the full set used by VKImage (depth, stencil, compute). Returns 4 with a warning for unknown formats, matching the previous VKImage fallback behaviour.
- Parameters
-
fmt Vulkan format.
- Returns
- Bytes per pixel, or 4 on unknown formats.
