colorsys.hsl_to_rgb(h, s, l), but not matplotlib.colors.hsl_to_rgb(array)

Hi all,

While working on this IPython Notebook http://nbviewer.ipython.org/github/empet/Math/blob/master/DomainColoring.ipynb

I wanted to compare the visual images of the same complex-valued function generated by the classical domain coloring method, using HSV, respectively HSL color model.

Unfortunately there is no matplotlib.colors.hsl_to_rgb(array) function, only colorsys.hsl_to_rgb(h,s,l). The latter acts on each pixel and is time consuming.

My question is, there is a special reason for which hsl_to_rgb is not implemented in matplotlib.colors for arrays?

I also looked in skimage.color http://scikit-image.org/docs/dev/api/skimage.color.html and couldn’t find such a function.

Is there a package containing such a conversion?

Thank you!

Em
