Constructors

InkCoverage(float, Point?, float, double, IReadOnlyDictionary<string, double>)

How much ink an InkRaster prints, from MeasureCoverage(float).

public InkCoverage(float MaxTotal, Point? MaxAt, float Limit, double ShareOver, IReadOnlyDictionary<string, double> PerPlate)

Parameters

MaxTotal float

The largest total of the printing inks on one pixel, as a fraction (3.2 is 320%).

MaxAt Point?

Where that total is (the first such pixel), or null for a raster with no ink.

Limit float

The total ink limit measured against, as a fraction.

ShareOver double

The share of pixels whose total exceeds Limit, 0 to 1.

PerPlate IReadOnlyDictionary<string, double>

Each plate's mean coverage, 0 to 1, by ink name; technical inks included.

Examples

// How the plates look on screen, and whether they print within the press's total ink limit.
using Raster<Rgba8> proof = page.Proof<Rgba8>(new ProofOptions { SimulatePaper = true });
InkCoverage coverage = page.MeasureCoverage(limit: 3.0f);
bool tooMuchInk = coverage.MaxTotal > coverage.Limit;      // where: coverage.MaxAt; how often: coverage.ShareOver
