#[no_mangle]pub unsafe extern "C" fn gifski_add_frame_rgba(
handle: *const GifskiHandle,

width: u32,
height: u32,
pixels: *const RGBA8,
presentation_timestamp: f64
) -> GifskiError
Pixels is an array width×height×4 bytes large. The array is copied, so you can free/reuse it immediately.
Presentation timestamp (PTS) is time in seconds, since start of the file (at 0), when this frame is to be displayed.
For a 20fps video it could be frame_number/20.0
.
Frames with duplicate or out-of-order PTS will be skipped.
The first frame should have PTS=0. If the first frame has PTS > 0, it'll be used as a delay after the last frame.
Returns 0 (GIFSKI_OK
) on success, and non-0 GIFSKI_*
constant on error.
