Class

UIGraphicsRendererFormat

A set of drawing attributes that represent the configuration of a graphics renderer context.

Declaration

class UIGraphicsRendererFormat : NSObject

Overview

Create a UIGraphicsRendererFormat object, or one of its subclasses (UIGraphicsImageRendererFormat and UIGraphicsPDFRendererFormat), and use it to construct a graphics renderer by providing the format object as a parameter in a UIGraphicsRenderer subclass intializer.

The graphics renderer uses the format object you provided to configure any context objects (UIGraphicsRendererContext) it creates as part of the rendering process.

If you use a graphics renderer initializer that does not require a format argument, the renderer creates a format object using the default() class method.

The renderer format object contains properties that represent the immutable aspects of the renderer's configuration. This means that repeated uses of a single graphics renderer object will always use the same format object.

Topics

Creating a Default Format

class func `default`() -> Self

Returns a new format configured for the highest fidelity supported by the current device.

Getting the Bounds

var bounds: CGRect

The bounds of the associated graphics context.

Type Methods

class func preferred() -> Self

Returns a new format best suited for the main screen’s current configuration.
