Image Feathering

[johnford]

Hi All,

Does anyone know how I can feather the edges of an image?

Regards,

John.

Depending what you want to do I remember Anthony said about using a gradiant to blend two pictures along one edge.

This is a link to a masking method I tried out - http://www.rubblewebs.co.uk/imagemagick ... r_soft.jpg

Or is it you want to make the edges of an image slightly transparent, or overlaying a masked image into another image?

Feathering in this case is usually done as part of the cutting process and not as a later step.

Hi,

Im trying to feather white all around an image.

Is this possible to do without using another image?

Pardon, feather all white?

You mean you have a image that is sitting on a white background, and you want to remove that background while preserving the anti-aliasing involved.

This is a real problem for which no ideal solution is currently available. That is not to say a solution could not be found, just not a simple solution.

What I do have has been placed online at

One other solution by Dr. Rick Mabry,

This basically is a gradient to gradient color replacement technique.
Such a technique with masking and overlaying will correctly re-create the right anti-aliased edging of a image. Or as you incorrectly put it 'feathering'.

Fortunately this technique is NOT available in IM, as basically we don't have enough programmers willing to work on the software core.

However if you like to publish a link to an example image I'll see what I can do about generating a example using IM techniques.
