public class Scale : Effect, IDisposable, IUnknown

Public Class Scale
    Inherits Effect
    Implements IDisposable, IUnknown

Name	Description
Scale(IntPtr)	Initializes a new instance of the Scale class.

Name	Description
BorderMode	The mode used to calculate the border of the image, soft or hard. See Border modes for more info.
CenterPoint	The image scaling center point. This property is a Vector2 defined as: (point X, point Y). The units are in DIPs. Use the center point property to scale around a point other than the upper-left corner.
InterpolationMode	The interpolation mode the effect uses to scale the image. There are 6 scale modes that range in quality and speed. If you don't select a mode, the effect uses the interpolation mode of the device context. See Interpolation modes for more info.
ScaleAmount	The scale amount in the X and Y direction as a ratio of the output size to the input size. This property a Vector2 defined as: (X scale, Y scale). The scale amounts are FLOAT, unitless, and must be positive or 0.
Sharpness	In the high quality cubic interpolation mode, the sharpness level of the scaling filter as a float between 0 and 1. The values are unitless. You can use sharpness to adjust the quality of an image when you scale the image down. The sharpness factor affects the shape of the kernel. The higher the sharpness factor, the smaller the kernel.
