Sample code on IM site fails

[sol90]

Hi there,

In trying the following code, I get an "unable to parse 'aa' error".

convert -size 100x100 xc: -fx 'aa=atan2(j-h/2+.5,i-w/2+.5)/pi/2; aa>0 ? aa : aa+1' hue_angular.png
convert -size 100x100 xc: -fx 'xx=i/w-.5; yy=j/h-.5; rr=sqrt(xx*xx+yy*yy); rr*2' luminence_radial.png

Can someone please post the correct code that will work?

Thanks!

You may need to upgrade your version of ImageMagick. The command lines work fine for us. Recent versions of ImageMagick permit assignments in the -fx argument (e.g. aa=atan2...).

What version exactly are you using?
I have the most recent version.

ImageMagick-6.3.5-3-Q16-windows-dll.exe
from http://www.imagemagick.org/script/binar ... hp#windows


If it helps, I'm on Windows XP typing in from command window.

We're using 6.3.5-3 as well. Perhaps under Windows you need to use double quotes rather than single quotes.

That did the trick. Thank you.
