template<class ImageType> void IP3D::TransformWithInverseField (  const ImageType &  imOrig, const Field3Df &  field, ImageType &  imRes )

#&TransformWithInverseField&# Use a vector field to apply a deformation on an image. If F is a vector field (3D image composed of 3D vectors), S the source image,R the result image, and P a point, we have: R(P)=S(P+F(P)). If no interpolator is present in source image, it will use a bspline 5th degree interpolator. If a mask is present, it will be transformed by creating seperate binary images for each different intensity value in the mask. Each binary (0 or 1) image is transformed using an interpolator (default bspline 5). The result mask is constructed by recombining the transformed floating point binary images. This gives MUCH better results than would be obtained by using nearest neighbor interpolation. This is however, very slow if mask contains many different intensity values. Source image 1 type:ImageType Deformation field type:Image3Dlinear<Vect3Df> Result image type:ImageType ~ Referenced by IP3D::TransformAffine(), and IP3D::TransformWithInverseField().

template<class ImageType> void IP3D::TransformAffine (  const ImageType &  imOrig, const Affine3DTransform &  transfo, ImageType &  imDest, const Size3D *  resSize = NULL )

#&TransformAffine&# Perform an affine transformation on an image Affine transforms are described by a 3x3 matrix and a translation vector. They can be stored in an ImLib3D format file (see Affine3DTransform). If no interpolator is present in source image, it will use a bspline 5th degree interpolator. If a mask is present, it will be transformed as described in TransformWithInverseField. If optional size is not ommited, result image will have same size as source image. Source image 1 type:ImageType Affine transform type:Affine3DTransform Result image type:ImageType Result image size type:Size3D ~ Referenced by IP3D::Scale().

template<class ImageType> void IP3D::Scale (  const ImageType &  src, const Size3D &  newSize, ImageType &  res )

#&Scale&# Change image size using resampling If no interpolator is present in source image, it will use a bspline 5th degree interpolator. If a mask is present, it will be transformed as described in TransformWithInverseField.

template<class ImageType> void IP3D::WrapTranslate (  const ImageType &  src, const Vect3Di &  t0, ImageType &  res0 )

#&WrapTranslate&# Translates an image by integer vector, and wraps around Transforms any masks as well.

Referenced by IP3D::GaussianApproxFilter().

template<class ImageType> void IP3D::Flip (  const ImageType &  src, const string &  axes, ImageType &  res0 )

#&Flip&# Flips image in one or more directions This is usefull when using images from various sources. Second argument is a string containing directions in which to flip. example: "XY" Source image type:ImageType direction type:string Result image type:ImageType ~ Definition at line 162 of file Transformation.hpp.

template<class ImageType> void IP3D::SwapAxes (  const ImageType &  src, const string &  axes, ImageType &  res0 )

#&SwapAxes&# Swaps axes This is usefull when using images from various sources. Second argument is a string containing axes to swap. example: "XY" will invert x and y axes Source image type:ImageType direction type:string Result image type:ImageType ~ Definition at line 204 of file Transformation.hpp. References ImageProcessorArgs< ImageType >::GetDest(), and ImageProcessorArgs< ImageType >::SetDestSize().
