FIL.ShearImage

Computes a leant image (shifts the rows).

Namespace:FilNet
Assembly:FIL.NET.dll

Syntax

C++
C#
 
public static void ShearImage
(
	FilNet.Image inImage,
	float inShear,
	FilNet.Axis inAxis,
	FilNet.InterpolationMethod inInterpolationMethod,
	FilNet.Image outImage
)

Parameters

Name Type Range Default Description
inImageFilNet.ImageInput image.
inShearfloat<-INF, INF>0.0fRelative shift between consecutive rows or columns of the image. Default value: 0.0f.
inAxisFilNet.AxisSwitches between horizontal or vertical shearing.
inInterpolationMethodFilNet.InterpolationMethodBilinearDefault value: Bilinear.
outImageFilNet.ImageOutput image.

Description

The filter ShearImage applies basic affine transform to each image's pixel.

Shear affine transform is defined as:

When X axis is selected

\[ \left[\begin{array}{ccc} x' \\ y' \end{array} \right] = \left[\begin{array}{ccc} 1 & inShear \\ 0 & 1 \end{array} \right] \left[\begin{array}{ccc} x \\ y \end{array} \right] \]

When Y axis is selected

\[ \left[\begin{array}{ccc} x' \\ y' \end{array} \right] = \left[\begin{array}{ccc} 1 & 0\\ inShear & 1 \end{array} \right] \left[\begin{array}{ccc} x \\ y \end{array} \right] \]

Examples

ShearImage performed on the sample image with inAxis = X, inShear = 0.50.
