Re: [Gimp-developer] efficient bilinear interpolation code
I've just submitted a patch for efficient bilinear interpolation of transformed brushes to bugzilla (Bug 520078 – Rotate brushes http://bugzilla.gnome.org/show_bug.cgi?id=520078). I have a feeling the speed could still be improved somehow, so any performance gurus looking for a challenge are welcome to give it a go.

You should be aware there is an occasional bug that occurs with very small brushes, with the current code, where eg. a 1x1pixel brush becomes a 4x1 pixel brush like this: #..# It is usually triggered by adjusting the brush scale away from 1.0 and then back to 1.0. I'm happy to help with testing the interpolation, especially if the above bug also appears with your code.
