would it make sense to use airspeed velocity at this point? As a pre/post AGG merge analysis? |
|
@WeatherGod: That's a good idea. |

Might have a useful test case for visual improvement: http://matplotlib.1069221.n5.nabble.com/Single-color-transparent-colormap-td44435.html |

@mdboom Punting to next point release. |
|
Wasn't this taken care of as part of the updating AGG? |
No -- the floating point buffer feature in Agg appears to be rather broken. Made some enquiries on the Agg mailing list but it hasn't gone anywhere, and I haven't had time to investigate myself. |

This looks moribund. Feel free to re-open if I'm wrong! |

This is an experiment to play with floating-point rendering buffers in Agg.
The final version will compile for both 8-bit-per-plane and 32-bit-floating-point-per-plane and allow the user to choose. But for now, this just does 32-bit-floating-point-per-plane.
Gouraud shading is broken (due to Agg), so it's disabled. Other things -- particularly backends other than TkAgg for now -- are unlikely to work. But it should be enough to experiment with so we can get a sense of the performance/quality tradeoffs.
