BilinearReverse doesnt work in 6.6.7-4

[ecoverguru]

I have imagemagick version 6.6.7-4 2011-02-01 Q16 installed, but "BilinearReverse " doesnt seems to work..

The documentation says "Before IM v6.5.1-2 the 'BilinearReverse' distortion was implemented simply as 'Bilinear'." so i guess in my version it should work right?

What was your exact command line?

Also the order of control points changed in more current versions. See http://www.imagemagick.org/Usage/distor ... rol_points

This works fine for me in IM 6.7.1.2 Q16 Mac OSX tiger:


convert mandril.jpg -matte -virtual-pixel black \
-distort BilinearReverse \
'0,0 26,0 128,0 114,23 128,128 128,100 0,128 0,123' \

I was actually trying to achieve the following with BilinearReverse but now it seems Polynomial '1.5 is an alternative.. here is the thread I wanted actually help for
