Constructors

Scale(IntPtr)

Initializes a new instance of the Scale class.

public Scale(IntPtr nativePtr)

Parameters

nativePtr System.IntPtr

The native pointer.

Properties

BorderMode

The mode used to calculate the border of the image, soft or hard. See Border modes for more info.

public BorderMode BorderMode { get; set; }

Property Value

BorderMode

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.

public Vector2 CenterPoint { get; set; }

Property Value

Vector2

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.

public InterpolationMode InterpolationMode { get; set; }

Property Value

InterpolationMode

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.

public Vector2 ScaleAmount { get; set; }

Property Value

Vector2

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.

public float Sharpness { get; set; }

Property Value

float

Remarks

This property affects only the high quality cubic interpolation mode.

Methods

Create(DeviceContext)

Initializes a new instance of Scale effect.

public static Scale Create(DeviceContext context)

Parameters

context DeviceContext

Returns

Scale
