heavily blur one fixed part of the image

[T o n g]

Hi,

Sorry if it's written somewhere. Please direct me to the info by which I
can heavily blur one fixed part of the image, say the lower-right
rectangular/oval corner.

I guess you've already known what I'm trying to do -- to me, for this
case, blur the corner out of shape is more important than preserving the
original content. That's why the "heavily blur" is in the subject.

Please help.

Thanks.

See Variable Blur Mapping....

http://www.imagemagick.org/Usage/mapping/#blur

the very first example is like what you are requesting.


However if you are 'spam' removing you may like to look at
the script
http://www.imagemagick.org/Usage/scripts/#hole_fill_shepards

Basically you make the unwanted part transparnent than pass it though
this script to replace that part with the color of the edges of the hole.

This is similar to what is described in
Removing text and Logos -- filling in 'holes' in a photo
http://www.imagemagick.org/Usage/photos/#removing

But uses shepards method, rather than a direct blur.
