R38 – BoxBlur is Best Blur

This release is mostly kind of a bug fix with minor enhancements as well. Nothing exciting but the restrictions of several filters were re-examined and relaxed a bit to match what the actual code can handle. As a result Transpose doesn’t care about subsampling anymore, horizontal and vertical convolutions have a larger element limit and AverageFrames can average over even more frames. Not very exciting at all for most people.

The other part is the addition of a box blur filter. The main attraction is that it can be used to approximate large radius Gaussian blurs very quickly. Or simply a large area average.

This release dragged on for far too long.

Possibly breaking changes:

  • ImageMagick7 is now required for the imwri plugin
  • Visual Studio 2017 is now officially required to build on windows
