SDL_DEFINE_PIXELFORMAT - Man Page

#include <SDL3/SDL_pixels.h>

#define SDL_DEFINE_PIXELFORMAT(type, order, layout, bits, bytes) \
    ((1 << 28) | ((type) << 24) | ((order) << 20) | ((layout) << 16) | \
     ((bits) << 8) | ((bytes) << 0))

For example, defining SDL_PIXELFORMAT_RGBA8888 looks like this:

SDL_DEFINE_PIXELFORMAT(SDL_PIXELTYPE_PACKED32, SDL_PACKEDORDER_RGBA, SDL_PACKEDLAYOUT_8888, 32, 4)

type

the type of the new format, probably a SDL_PixelType value.

order

the order of the new format, probably a SDL_BitmapOrder, SDL_PackedOrder, or SDL_ArrayOrder value.

layout

the layout of the new format, probably an SDL_PackedLayout value or zero.

bits

the number of bits per pixel of the new format.

bytes

the number of bytes per pixel of the new format.

Returns a format value in the style of SDL_PixelFormat.

It is safe to call this macro from any thread.

This macro is available since SDL 3.2.0.
