Geometric transformations using bilinear interpolation.
This file contains functions for bilinear resampling and 2D rotations. The transformation equation is:
y = A(x-x0) + b
where x,x0,b,y are 1x2 vectors and A is a 2x2 matrix. The vector x0 can be used to specify a position that remains unchanged by the transformation.

Resample a 2D image using bilinear interpolation.
src | input image (any repn) |
dest | output image (any repn) |
transform | 3x2 transformation image (float or double repn). The first column of <transform> contains the translation vector. The remaining three columns contains the 2x2 linear transformation matrix. |
r0 | row address that remains fixed |
c0 | column address that remains fixed |
dst_nrows | number of output rows |
dst_ncolumns | number of output columns |
