Constructors

Name Description

Initializes a new instance of the Scale class.

Properties

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.
