dmtools 0.3.0 Release Notes

The Gaussian filter was added to the list of built-in filters. Furthermore,
this filter was used to implement a Gaussian blurring function called blur
which can blur an image to varying degrees. In addition, the clip, normalize,
and wraparound functions were added to get values of an image into range
before exporting to PNG. This addition stemmed from a change in convention in
which image modification algorithms are no longer responsible for maintaining
a valid PNG image. Lastly, this release includes a patch for the Catmull-Rom
filter which was incorrectly implemented.
