Egami

Assembly

Egami.dll

What Probe(Stream, EgamiContext?, ReaderOptions?) reads from a header: the image as Probe(Stream, EgamiContext?, ReaderOptions?) describes it, and the planes Load(Stream, EgamiContext?, ReaderOptions?) would give, if any.

// Saving JPEG-colored 8-bit planes skips color conversion and downsampling; other planes are converted first.

YuvRasterInfo(RasterInfo, ChromaFormat?, int, YuvColor?)

What Probe(Stream, EgamiContext?, ReaderOptions?) reads from a header: the image as Probe(Stream, EgamiContext?, ReaderOptions?) describes it, and the planes Load(Stream, EgamiContext?, ReaderOptions?) would give, if any.

public YuvRasterInfo(RasterInfo Info, ChromaFormat? ChromaFormat, int BitDepth, YuvColor? Color)

Parameters

Info RasterInfo

The image, as Probe(Stream, EgamiContext?, ReaderOptions?) describes it.

ChromaFormat ChromaFormat?

The planes' chroma format, or null when loading planes is not supported.

BitDepth int

The planes' bits per sample, or 0.

Color YuvColor?

The planes' color description, or null.

Examples

// A JPEG's own planes, as decoded: no chroma upsampling and no color conversion.
YuvRasterInfo info = YuvRaster.Probe("duck.jpg");
Console.WriteLine($"{info.Info.Width}×{info.Info.Height}, planes: {info.ChromaFormat}");
using YuvRaster planes = YuvRaster.Load("duck.jpg");

// Saving JPEG-colored 8-bit planes skips color conversion and downsampling; other planes are converted first.
planes.Save("copy.jpg", new JpegWriterOptions { Quality = 90 });
