Warp image
warp(im, warpfield, mode = 0L, interpolation = 1L, boundary_conditions = 0L)
im |
an image |
warpfield |
Warping field. The (x,y,z) fields should be stacked along the colour coordinate. |
mode |
Can be 0=backward-absolute | 1=backward-relative | 2=forward-absolute | 3=forward-relative |
interpolation |
Can be <tt> 0=nearest | 1=linear | 2=cubic </tt>. |
boundary_conditions |
Boundary conditions. Can be <tt> 0=dirichlet | 1=neumann | 2=periodic </tt>. |
