示例1: reduceExample

# 需要导入模块: import Polygon [as 别名]
# 或者: from Polygon import shift [as 别名]
def reduceExample():
    # read Polygon from file
    p = Polygon('testpoly.gpf')
    # use ireland only, I know it's contour 0
    pnew = Polygon(p[0])
    # number of points
    l = len(pnew[0])
    # get shift value to show many polygons in drawing
    bb = pnew.boundingBox()
    xs = 1.1 * (bb[1]-bb[0])
    # list with polygons to plot
    plist = [pnew]
    while l > 30:
        # reduce points to the half
        l /= 2
        print "Reducing contour to %d points" % l
        pnew = Polygon(reducePoints(pnew[0], l))
        pnew.shift(xs, 0)
        plist.append(pnew)
    # draw the results
    print "Plotting ReduceExample.svg"
    drawSVG(plist, height=400, ofile="ReduceTest.svg")
