Enum JpegChromaSubsampling

Namespace

LMKit.Media.Image

Assembly

LM-Kit.NET.dll

How much colour detail a JPEG keeps relative to its brightness detail (ChromaSubsampling). The eye resolves brightness more finely than colour, so dropping chroma samples is the cheapest way to shrink a photograph; it costs sharpness on coloured edges, text and graphics.

public enum JpegChromaSubsampling

Fields

Auto = 0

Full colour (4:4:4) from quality 90 up, quarter colour (4:2:0) below - the choice a careful tool makes once the quantizer no longer hides the missing chroma. The default.

Full = 1

4:4:4 - every pixel keeps its own colour. Sharpest, largest.

Half = 2

4:2:2 - colour halved horizontally.

Quarter = 3

4:2:0 - colour halved in both directions, the web default.
