  1. If you go to the Incompetech Multi-Color Graph Paper PDF Generator<\/a> and set the grid spacing to 0.4, 0.8 and 4 lines\/cm, you get a nifty HP-GL unit grid with major lines at 1000 units (25 mm), intermediate lines at 500 units (12\u00c2\u00bd mm) and minor lines at 100 units (2\u00c2\u00bd mm):

  2. By a very roundabout route, I used GDAL’s simplify<\/a> function to half the line count of my hypotrochoid plots with little visible degradation. The optimised page took far less time to plot:
    \n    \"hypo1\"<\/a>
    \n    \"hypo2\"<\/a>
    \nNext time, I’d definitely use     Shapely<\/a> instead of messing about with GIS formats. Who knows, I might even integrate it into Chiplotle<\/a>. Eventually. (Update<\/strong>: though I have some code<\/a> that does something \u00e2\u20ac\u00a6)<\/li>\n
  3. 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: http:\/\/scruss.com\/wordpress\/wp-content\/uploads\/2014\/03\/hp7470a-plotter.mp3<\/a><\/audio>.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
