Hi,
When trying some examples from the IM Usage website, they result in
errors. E.g. (from Usage/canvas/#gradient):
$ convert -size 100x100 xc: \
-fx 'xx=i/w-.5; yy=j/h-.5; rr=sqrt(xx*xx+yy*yy); 1-rr*1.42' \
gradient_fx_radial.gif
convert: unable to parse expression `xx'.
$ convert -size 100x100 xc: \
-fx 'xx=i/w-.5; yy=j/h-.5; rr=xx*xx+yy*yy; 1-rr*4' \
gradient_fx_spherical.gif
convert: unable to parse expression `xx'.
Are the examples wrong, or...?
