Fields

Rec601 = 1

Examples

photo.Apply(ops => ops
    .Brightness(1.05f)     // 1 changes nothing
    .Contrast(1.1f)
    .Saturation(1.2f)
    .HueRotate(10), Ct);    // these four run as one pass

using Raster bw = photo.Derive(ops => ops.Grayscale(LumaWeights.Rec709), Ct);
using Raster old = photo.Derive(ops => ops.Sepia(0.8f).Opacity(0.9f), Ct);
