AffineTransformation2D¶

MLModule¶

genre	`SpatialTransformation`
author	`MeVis Medical Solutions AG`
package	`MeVisLab/Standard`
dll	`MLTransformation`
definition	MLTransformation.def
keywords	`rotate`, `translate`, `shear`, `scale`, `image`

Purpose¶

The module AffineTransformation2D performs a 2D affine transformation.

The transformation is applied on each image slice.

Usage¶

Translation, rotation, shearing, and scaling can be entered and reset.

Limitations: works efficiently only with data types of < uint16.

Details¶

All parameters are relative in [-1, 1].

The translation is applied after the other transformations.

Tips¶

For more detailed information see the documentation of AffineTransformation3D.

Scaling Y: Double

Shearing: Double

Translation X: Double

Translation Y: Double

Opt Parameters¶

name: optParameters, type: String, default: 0 0 0 0 1 1¶

Sets optionally all values in a single string. The order is: translation x, translation y, rotation, shearing, scaling x, and scaling y.

The order is just the order of the parameters on the GUI.

Translation X¶

name: translationX, type: Double, default: 0¶: Sets the relative translation in the x-direction.

Translation Y¶

name: translationY, type: Double, default: 0¶: Sets the relative translation in the y-direction.

Rotation¶

name: rotation, type: Double, default: 0¶: Sets a rotation value in radians.

Shearing¶

name: shearing, type: Double, default: 0¶: Sets the x/y ratio.

Scaling X¶

name: scalingX, type: Double, default: 1¶

Sets a reciprocal value for scaling in the x-direction.

E.g., 0.5 zooms in the image by 2.

Scaling Y¶

name: scalingY, type: Double, default: 1¶

Sets a reciprocal value for scaling in the y-direction.
