Public Constructors

public Rot90Op ()

Creates a Rot90 Op which will rotate image by 90 degree counter-clockwise.

public Rot90Op (int k)

Creates a Rot90 Op which will rotate image by 90 degree for k times counter-clockwise.

Parameters

| k | The number of times the image is rotated by 90 degrees. If it's positive, the image will be rotated counter-clockwise. If it's negative, the op will rotate image clockwise. |

Public Methods

public TensorImage apply (TensorImage image)

Applies the defined rotation on given image and returns the result.

Note: the content of input image will change, and image is the same instance with the output.

Parameters

| image | input image. |

Returns

• output image.

public int getOutputImageHeight (int inputImageHeight, int inputImageWidth)

Computes the height of the expected output image when input image size is given.

Parameters

| inputImageHeight | | | inputImageWidth | |

public int getOutputImageWidth (int inputImageHeight, int inputImageWidth)

Computes the width of the expected output image when input image size is given.

Parameters

| inputImageHeight | | | inputImageWidth | |

public PointF inverseTransform (PointF point, int inputImageHeight, int inputImageWidth)

Transforms a point from coordinates system of the result image back to the one of the input image.

Parameters

| point | the point from the result coordinates system. | | inputImageHeight | the height of input image. | | inputImageWidth | the width of input image. |

Returns

• the point with the coordinates from the coordinates system of the input image.
