Hi

can anyone tell me where (and how to get rid of) the 'mirror image'
when using something like the following when demagnifying and warping
images:

testimage = findgen (100,100)
window, 1, xs = 100, ys = 100
wset, 1
tvscl, testimage
wait, 2
xi = [10,90,90,10]
yi = [90,90,10,10]
xo = [45,55,55,40] ; here the image is 'sheared' by the last point
yo = [55,55,45,40]
POLYWARP, xi,yi,xo,yo,1,P,Q
Warped_Image =(POLY_2D(testimage,P,Q, missing = 255))
tvscl, warped_image

Cheers

david
