The documentation http://www.imagemagick.org/script/comma ... s.php#blur includes:

-blur Width[xHeight[+Angle]]

Variably blur an image according to the overlay mapping.

But this doesn't work. "-blur 1x5+45" gives exactly the same result as "-blur 1x5", which is radius 1 sigma 5.

And if the angle is optional, there is no way for IM to distinguish WidthxHeight from RadiusxSigma.

I don't know if the "-blur Width[xHeight[+Angle]]" version is an old command, or an aspiration, or what.

I think this is really for -compose blur at http://www.imagemagick.org/Usage/mapping/#blur. The only thing that is missing in the documentation is to associate it with a -compose method.

Including it under "-set" or "-define" would be fair enough. But it is listed as a standalone option with a "-" in front of it.

But this is wrong. There is no option "-blur WidthxHeight+Angle".

You are correct. But I am not sure how to fix that. It is documented at http://www.imagemagick.org/script/compose.php. So perhaps it just should be removed from the "convert" methods list all together.

If magick agrees, then I can just remove it.

Fixed. Allow 24 hours for the change to mirror world-wide.
