// Defines what happens at the edge of the gradient.
//
// A gradient is defined along a finite inner area. In the case of a linear
// gradient, it's between the parallel lines that are orthogonal to the line
// drawn between two points. In the case of radial gradients, it's the disc
// that covers the circle centered on a particular point up to a given radius.
//
// This enum is used to define how the gradient should paint the regions
// outside that defined inner area.
//
// See also:
//
// * [LinearGradientShader], [RadialGradientShader] which works in
// relative coordinates and can create a [Shader] representing the gradient
// for a particular [Rect] on demand.
enum class TileMode {
// Edge is clamped to the final color.
//
// The gradient will paint the all the regions outside the inner area with
// the color of the point closest to that region.
//
Clamp,
// Edge is repeated from first color to last.
//
// This is as if the stop points from 0.0 to 1.0 were then repeated from 1.0
// to 2.0, 2.0 to 3.0, and so forth (and for linear gradients, similarly from
// -1.0 to 0.0, -2.0 to -1.0, etc).
Repeated,
// Edge is mirrored from last color to first.
//
// This is as if the stop points from 0.0 to 1.0 were then repeated backwards
// from 2.0 to 1.0, then forwards from 2.0 to 3.0, then backwards again from
// 4.0 to 3.0, and so forth (and for linear gradients, similarly from in the
// negative direction).
