Inherits from TKGradientFill : TKFill : NSObject
Declared in TKRadialGradientFill.h

Overview

Represents a radial fill.

Tasks

Properties

endCenter

The end center for radial gradients. The default value is (0.5f, 1.0f).

@property (nonatomic, assign) CGPoint endCenter

Declared In

TKRadialGradientFill.h

endRadius

The radius of a end circle with center at the end point. Used only for radial gradients. The default value is 0.5 (with TKGradientRadiusType = TKGradientRadiusTypeRectMin).

@property (nonatomic, assign) CGFloat endRadius

Declared In

TKRadialGradientFill.h

gradientRadiusType

The units used for startRadius and endRadius. The default value is TKGradientRadiusTypeRectMin.

@property (nonatomic, assign) TKGradientRadiusType gradientRadiusType

Discussion

The radius types are defined as follows:

typedef enum {
    TKGradientRadiusTypePixels,     // The radius is in pixels.
    TKGradientRadiusTypeRectMin,    // The radius is in the interval of 0 (0%) to 1 (100%) using minimum of drawing rectangle sizes.
    TKGradientRadiusTypeRectMax     // The radius is in interval of 0 (0%) to 1 (100%) using maximum of drawing rectangle sizes.
} TKGradientRadiusType;

startCenter

The start center for radial gradients. The default value is (0.5f, 0.0f).

@property (nonatomic, assign) CGPoint startCenter

Declared In

startRadius

The radius of a start circle with center at the start point. Used only for radial gradients. The default value is 0.5 (with TKGradientRadiusType = TKGradientRadiusTypeRectMin).

@property (nonatomic, assign) CGFloat startRadius
