Instance Method Summary

• #finalize
• #input_format : PixelFormat
• #input_height : Int32
• #input_width : Int32
• #output_format : PixelFormat
• #output_frame : Frame

  create a compatible output frame for storing the scaled result

• #output_height : Int32
• #output_width : Int32
• #scale(input : Frame, output : Frame = output_frame)

  scales and optionally changes format of a frame

• #scaling_method : ScalingAlgorithm
• #unsafe_scale(input : Frame, output : Frame = output_frame)

  like scale but without the checks if you need the speed
