GradientType

public enum GradientType

Defines the different type of supported gradients.

  • Defines a linear gradient type, along the specified direction. When used with GradientView, direction is scaled to the bounds of the view.

    Examples

  • .linear(direction: CGPoint(x: 0.0, y: 1.0): Define a gradient going from the left edge to the right edge.
  • .linear(direction: CGPoint(x: 1.0, y: 1.0): Define a gradient going from the top-left corner to the bottom-right corner.
  • .linear(direction: CGPoint(x: -1.0, y: -1.0): Define a gradient going from the bottom-right corner to the top-left corner.
  • .linear(direction: CGPoint(x: -1.0, y: 0.0): Define a gradient going from the bottom edge to the top edge.

  • .linear(direction: CGPoint(x: 0.0, y: 0.5): Define a gradient going from the top edge to the middle, extending the last color until the bottom edge.

    • Note

    If direction is .zero, only the endColor of the Definition will be drawn. See GradientView.Definition.endColor for more info about what this property refers to.

    Declaration

    Swift

    case linear(direction: CGPoint)

  • Defines a radial gradient type, starting at the specified center with the given initial radius, and expanding/reducing to the specified center and final radius. When used with GradientView, startCenter and endCenter is scaled to the bounds of the view. startRadius and endRadius are not scaled.

    Examples

  • .radial(startCenter: CGPoint(x: 0.5, y: 0.5), startRadius: 10.0, endCenter: CGPoint(x: 0.5, y: 0.5), endRadius: 200.0): Define a radial gradient that starts in the center of the view with an initial radius of 10, and expands to a radius of 200 without changing its center.

  • .radial(startCenter: CGPoint(x: 0.0, y: 0.5), startRadius: 200.0, endCenter: CGPoint(x: 1.0, y: 0.5), endRadius: 10.0): Define a radial gradient that starts in the left edge of the view centered vertically with an initial radius of 200, and reduce to a radius of 50 to the right-most edge centered vertically.

    • Note

    When using different centers for a radial gradient, the resulting gradient might be unexpected.

    Declaration

    Swift

    case radial(startCenter: CGPoint, startRadius: CGFloat, endCenter: CGPoint, endRadius: CGFloat)
