Expand description

NSNumber (float) : The desired scale factor at which the image will be eventually drawn. Setting this value can greatly improve the drawing performance. A value of 1 would mean identity, values smaller than 1 will result in a smaller output image. Changing the Scale Factor with enabled Draft Mode may also improve performance.
