Detailed Description

A structure that represents a color as RGBA components.

The bits of this structure can be directly reinterpreted as an integer-packed color which uses the PIXELFORMAT_RGBA32 format (PIXELFORMAT_ABGR8888 on little-endian systems and PIXELFORMAT_RGBA8888 on big-endian systems).

Since

This struct is available since SDL 3.2.0.
