Enum RawDemosaicMethod

Namespace

Egami.Formats.Extended.Raw

Assembly

Egami.Formats.Extended.dll

How a develop fills in the colours a colour filter array did not sample.

public enum RawDemosaicMethod

Fields

Ahd = 2

Hirakawa and Parks' adaptive homogeneity-directed interpolation: the fewest colour artifacts on fine detail. The default.

Bilinear = 0

The average of the nearest samples of each colour. Fastest, softest.

Malvar = 1

Malvar, He and Cutler's gradient-corrected interpolation: sharper than bilinear at almost the same speed.

Examples

RawReaderOptions develop = new()
{
    WhiteBalance = RawWhiteBalance.Custom,
    Temperature = 4800,                    // kelvin
    Tint = 5,                              // toward magenta
    Exposure = -0.5,                       // stops
    Highlights = RawHighlightMode.Rebuild, // recover clipped colour from what was not clipped
    Demosaic = RawDemosaicMethod.Malvar,   // faster than the default AHD
    LuminanceNoiseReduction = 20,          // 0 to 100; off by default
    ColorNoiseReduction = 40,              // 0 to 100; 25 by default
    AutoChromaticAberration = true,        // fix colour fringes when no lens profile covers the file
    DefaultToneCurve = true,               // a contrast curve like Adobe Camera Raw's default; off by default
    ConvertColorTo = Colors.ColorProfile.DisplayP3, // rendered straight into P3, the profile attached
};
using Raster photo = Raster.Load("photo.dng", context, develop);
photo.Save("photo-p3.png");
