A set of drawing attributes that represents the configuration of an image renderer context.
Declaration
class UIGraphicsImageRendererFormatOverview
Use an instance of UIGraphicsImageRendererFormat to initialize a UIGraphicsImageRenderer object with nondefault attributes.
The image renderer format object contains properties that determine the attributes of the underlying Core Graphics contexts that the image renderer creates. Use the default() class method to create an image renderer format instance optimized for the current device.
