PdfGradient class

A gradient ready for a device: stops pre-sampled from the shading's function, with geometry in the space mapped by transform.

Constructors

PdfGradient({required bool isRadial, required List<double> coords, required List<PdfColor> colors, required List<double> stops, required PdfMatrix transform, bool extendStart = true, bool extendEnd = true, PdfInkColorants? inkAt(double parameter)?})

Properties

averageColor → PdfColor

no setter

colors → List<PdfColor>

final

coords → List<double>

Axial: [x0, y0, x1, y1]. Radial: [x0, y0, r0, x1, y1, r1].

final

extendEnd → bool

final

extendStart → bool

PDF /Extend semantics: an extended end clamps to its terminal color, an unextended end paints nothing beyond the gradient geometry.

final

hashCode → int

The hash code for this object.

no setter, inherited

inkAt → PdfInkColorants? Function(double parameter)?

Device-colorant reading at normalized shading parameter 0..1.

final

isRadial → bool

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

stops → List<double>

final

transform → PdfMatrix

Maps gradient (pattern/shading) space to page space.

final

Methods

colorAt(double parameter) → PdfColor

The same piecewise-linear colour interpolation a painting device applies to the pre-sampled stops.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
