描述
polar_trans_contour_xld_invpolar_trans_contour_xld_invPolarTransContourXldInvPolarTransContourXldInvPolarTransContourXldInvpolar_trans_contour_xld_inv transforms the polar coordinate
representation of a contour, stored in PolarContourPolarContourPolarContourPolarContourpolarContourpolar_contour, back
onto an annular arc in Cartesian coordinates, described by the radii
RadiusStartRadiusStartRadiusStartRadiusStartradiusStartradius_start and RadiusEndRadiusEndRadiusEndRadiusEndradiusEndradius_end and the angles
AngleStartAngleStartAngleStartAngleStartangleStartangle_start and AngleEndAngleEndAngleEndAngleEndangleEndangle_end with the center point
located at (RowRowRowRowrowrow, ColumnColumnColumnColumncolumncolumn). All of these values can
be chosen as real numbers. In addition, the dimensions of the
virtual image containing the contour PolarContourPolarContourPolarContourPolarContourpolarContourpolar_contour must be
given in WidthInWidthInWidthInWidthInwidthInwidth_in and
HeightInHeightInHeightInHeightInheightInheight_in. WidthInWidthInWidthInWidthInwidthInwidth_in-1 is the column coordinate
corresponding to AngleEndAngleEndAngleEndAngleEndangleEndangle_end and HeightInHeightInHeightInHeightInheightInheight_in-1 is the
row coordinate corresponding to
RadiusEndRadiusEndRadiusEndRadiusEndradiusEndradius_end. AngleStartAngleStartAngleStartAngleStartangleStartangle_start and RadiusStartRadiusStartRadiusStartRadiusStartradiusStartradius_start
correspond to column and row coordinate 0. Furthermore, the
dimensions WidthWidthWidthWidthwidthwidth and HeightHeightHeightHeightheightheight of the virtual output
image containing the transformed contour XYTransContourXYTransContourXYTransContourXYTransContourXYTransContourxytrans_contour are
required. The output contour is cropped at the borders of this
virtual output image.
polar_trans_contour_xld_invpolar_trans_contour_xld_invPolarTransContourXldInvPolarTransContourXldInvPolarTransContourXldInvpolar_trans_contour_xld_inv is the inverse function of
polar_trans_contour_xldpolar_trans_contour_xldPolarTransContourXldPolarTransContourXldPolarTransContourXldpolar_trans_contour_xld。

returns the contour
ContourContourContourContourcontourcontour, restricted to the circle
around (
RowRowRowRowrowrow,
ColumnColumnColumnColumncolumncolumn) with radius
RadiusRadiusRadiusRadiusradiusradius,
as its output contour
XYTransContourXYTransContourXYTransContourXYTransContourXYTransContourxytrans_contour.
Note that XYTransContourXYTransContourXYTransContourXYTransContourXYTransContourxytrans_contour can consist of more than one
contour because PolarContourPolarContourPolarContourPolarContourpolarContourpolar_contour may be cropped at the borders
of the virtual output image given by WidthWidthWidthWidthwidthwidth and
HeightHeightHeightHeightheightheight。
If more than one contour is passed in PolarContourPolarContourPolarContourPolarContourpolarContourpolar_contour, their
transformations are computed individually and stored as a tuple in
XYTransContourXYTransContourXYTransContourXYTransContourXYTransContourxytrans_contour. However, since one contour may be
transformed into several contours, there is no relation between the
indices of the contours in the input tuple PolarContourPolarContourPolarContourPolarContourpolarContourpolar_contour and
the indices in the output tuple XYTransContourXYTransContourXYTransContourXYTransContourXYTransContourxytrans_contour。

注意
Only the contour points are transformed. As the polar transformation
is not affine, polar_trans_contour_xld_invpolar_trans_contour_xld_invPolarTransContourXldInvPolarTransContourXldInvPolarTransContourXldInvpolar_trans_contour_xld_inv only produces
reliable results if the spacing of the contour points is
small. Existing attributes are not transformed.
