Enum PerspectiveTransform3DInterpolationMode

The interpolation mode the PerspectiveTransform3D effect uses on the image. There are 5 scale modes that range in quality and speed.

public enum PerspectiveTransform3DInterpolationMode

Fields

NearestNeighbor = 0: Samples the nearest single point and uses that. This mode uses less processing time, but outputs the lowest quality image.
Linear = 1: Uses a four point sample and linear interpolation. This mode uses more processing time than the nearest neighbor mode, but outputs a higher quality image.
Cubic = 2: Uses a 16 sample cubic kernel for interpolation. This mode uses the most processing time, but outputs a higher quality image.
MultisampleLinear = 3: Uses 4 linear samples within a single pixel for good edge anti-aliasing. This mode is good for scaling down by small amounts on images with few pixels.
Anisotropic = 4: Uses anisotropic filtering to sample a pattern according to the transformed shape of the bitmap.
