Magick ++ dilate/erode

[cecchisandrone]

Hi,

I'm using Magick++ and I want to solve this problem. I have the following image. What that I need is to smooth it, to fill holes and make the difference between white and blue more clear. At the end I need only the colors previously existent: black, blue and white, with no shadings.
What kind of transformation do I need to solve this?

Thanks in advance for help.

I'm thinking about morphological opening/closing (dilate/erode) operations. How can I do them?

ImageMagick does not include a dilation operations, however, you can implement one yourself by using a Magick++ pixel iterator.

Fred Wienhaus has some command line shell scripts that implements this, but we have yet to find anyone willing to create these image filters inside magick core library.
