pub enum JpegSubsampling {
Yuv420,
Yuv422,
Yuv444,
}Expand description
Chroma subsampling mode for JPEG encoders.
Variants§
Yuv420
4:2:0 — chroma at quarter resolution. Smallest files; the usual default.
Yuv422
4:2:2 — chroma at half horizontal resolution.
Yuv444
4:4:4 — full-resolution chroma. Largest files, best chroma fidelity.
