[magick-users] filter image to use in opengl

[Cedric Pinson]

Hi,

I have an image exported by inkscape to use in a 3d program, my problem 
is that the border of the image is not really conveniant with the alpha 
blending.
What i would like is to process the image to extend the border of the 
rgb then the aplha will fade to the good color of border and not a 
background flat white.
I thought to a filter that could detect the border of image then extend 
it, but i did not success to do it. I am not really experienced in 
filter processing, so advise will be welcome.

here the picture to understand what i am explaining
