Type Property

scaleFactor

A key for the scale factor. The associated value is a floating-point value packaged as an NSNumber object that specifies the desired scale factor at which the image will be drawn. Setting this value can greatly improve the drawing performance. A value of 1 is the identity. In some cases, if you change the scale factor and enable draft mode, performance can decrease. See allowDraftMode.
