- By a very roundabout route, I used GDAL’s simplify function to half the line count of my hypotrochoid plots with little visible degradation. The optimised page took far less time to plot:
Next time, I’d definitely use Shapely instead of messing about with GIS formats. Who knows, I might even integrate it into Chiplotle. Eventually. (Update: though I have some code that does something â€¦)
- Plotters are resolutely electromechanical devices. They turn digital command into analogue output, but my one never sounds too happy doing it. It grumbles, sighs and even moos as it plots. A recent plot sounded a bit like this: .
