lilypond uses TeX to create "engraved sheet music." So I'd imagine it would create PDFs that could be converted to other formats. From a cursory look it appears that music21 has good support for MusicXML so that might be a way to interoperate between the pieces. Sample (unencumbered) score

[sage-devel] invisible contour lines in contour plots

2015-12-08 Thread Ursula Whitcher
In Sage's contour plots, the default colors shade from black to white. This applies to both the shades used to fill and the actual color of the contour lines. If you turn off the fill color, the highest contour will be white-on-white, and thus invisible. Here's an example (notice the label f
