Reform

The script calls are :

vcm.Reform (clip, clip bkg[, int intq = 2][,int norm = 1][,float rect =[x0= left top x, y0= left top y, x2= right bottom x,y2= right bottom y] ],float quad[x0,y0,x1,y1.x2,y2,x3,y3][, int q2r = 0])

clip:input clip. quadrilateral and rectangle transform is on this clip. YUV, RGB and GRAY constant formats.
bkg:background clip of identical format of input clip.
intq: interpolation type. 0 for point, 1 bilinear 2x2, 2 bicubic 4x4 and 3 Lanczos 6X6
norm: 0. for real and 1 for normalized values specified for coordinates.
rect: x and y coordinates of opposite corners of rectangle.
quad: quadrilateral x, y coordinates in clock wise starting that will transform to or from rectangle.
q2r: 0 for rect to quad and 1 for quad to rect transform.
