Detailed Description

Immutable wrapper for various shadow drawing properties.

See also

See Apple’s Quartz 2D and CGContext documentation for more information about each of these properties.

In general, you will want to create a CPTMutableShadow if you want to customize properties.

Method Documentation

init

- (nonnull instancetype) init

implementation

Initializes a newly allocated CPTShadow object.

The initialized object will have the following properties:

• shadowOffset = (0.0, 0.0)
• shadowBlurRadius = 0.0
• shadowColor = nil

Returns

The initialized object.

setShadowInContext:

- (void) setShadowInContext:

(nonnull CGContextRef)

context

Sets the shadow properties in the given graphics context.

Parameters

context

The graphics context.

shadow

+ (nonnull instancetype) shadow

Creates and returns a new CPTShadow instance.

Returns

A new CPTShadow instance.

Property Documentation

shadowBlurRadius

- (CGFloat) shadowBlurRadius

readnonatomicassign

The blur radius, measured in the default user coordinate space. A value of 0.0 (the default) indicates no blur, while larger values produce correspondingly larger blurring. This value must not be negative.

shadowColor

- (nullable CPTColor *) shadowColor

readnonatomicassign

The shadow color. If nil (the default), the shadow will not be drawn.

shadowOffset

- (CGSize) shadowOffset

readnonatomicassign

The horizontal and vertical offset values, specified using the width and height fields of the CGSize data type. The offsets are not affected by custom transformations. Positive values extend up and to the right. Default is (0.0, 0.0).
