TriangleMesh

class TriangleMesh(val colorSpace: ColorSpace, val background: RgbColor?, val bbox: Rectangle?, val triangles: List<KiteShading.MeshTriangle>) : KiteShading

Types 4/5: a triangle mesh with per-vertex colours.

Constructors

TriangleMesh

constructor(colorSpace: ColorSpace, background: RgbColor?, bbox: Rectangle?, triangles: List<KiteShading.MeshTriangle>)

Properties

background

open override val background: RgbColor?

Optional /Background colour, used for regions outside the shading domain when Extend is false on the relevant side. Per spec the background is in colorSpace; we eager-convert to RGB.

bbox

open override val bbox: Rectangle?

Optional clipping rectangle (/BBox) in shading-space.

colorSpace

open override val colorSpace: ColorSpace

The shading's colour space (DeviceGray / DeviceRGB / DeviceCMYK / Indexed).

triangles

val triangles: List<KiteShading.MeshTriangle>

Functions

sampleStops

fun KiteShading.sampleStops(count: Int = 32): GradientStops?

Sample a KiteShading.Axial or KiteShading.Radial at evenly-spaced stops between domain[0] and domain[1]. Returns parallel t and RGB arrays the backend uses to build a gradient brush.
