Method Detail

transformScale

public static PixelTransformAffine_F32 transformScale(ImageBase from,
                                      ImageBase to)

Computes a transform which is used to rescale an image. The scale is computed directly from the size of the two input images and independently scales the x and y axises.

transformRotate

public static PixelTransformAffine_F32 transformRotate(float x0,
                                       float y0,
                                       float x1,
                                       float y1,
                                       float angle)

Creates a PixelTransformAffine_F32 from the dst image into the src image.

Parameters:

x0 - Center of rotation in input image coordinates.

y0 - Center of rotation in input image coordinates.

x1 - Center of rotation in output image coordinates.

y1 - Center of rotation in output image coordinates.

angle - Angle of rotation.

createDistortMS

public static <T extends ImageSingleBand> ImageDistort<MultiSpectral<T>> createDistortMS(java.lang.Class<T> imageType,
                                                                         PixelTransform_F32 dstToSrc,
                                                                         InterpolatePixelS<T> interp,
                                                                         ImageBorder border)

Creates a ImageDistort for the multi-spectral images of the specified image type, transformation and interpolation instance.

Parameters:

dstToSrc - Transform from dst to src image.

interp - Which interpolation algorithm should be used.

border - Specifies how requests to pixels outside the image should be handled. If null then no change happens to pixels which have a source pixel outside the image.
