<dl><dt><a name="RendererPS-draw_line_collection"><strong>draw_line_collection</strong></a>(self, segments, transform, clipbox, colors, linewidths, linestyle, antialiaseds, offsets, transOffset)</dt><dd><tt>This is a function for optimized line drawing. If you need to draw<br>
many line segments with similar properties, it is faster to avoid the<br>
overhead of all the object creation etc. The lack of total<br>
configurability is compensated for with efficiency. Hence we don't use<br>
a GC and many of the line props it supports. See<br>
matplotlib.collections for more details.<br>
<br>
segments is a sequence of ( line0, line1, line2), where linen =<br>
is an Mx2 array with columns x, y. Each line can be a<br>
different length<br>
<br>
transform is used to Transform the lines<br>
<br>
clipbox is a xmin, ymin, width, height clip rect<br>
<br>
colors is a tuple of RGBA tuples<br>
<br>
linewidths is a tuple of linewidths<br>
*** really should be called 'dashes' not 'linestyle', since<br>
we call gc.set_dashes() not gc.set_linestyle() ***<br>
<br>
linestyle is an (offset, onoffseq) tuple or None,None for solid<br>
<br>
antialiseds is a tuple of ones or zeros indicating whether the<br>
segment should be aa or not<br>
<br>
offsets, if not None, is an Nx2 array of x,y offsets to<br>
translate the lines by after transform is used to transform<br>
the offset coords<br>
<br>
This function could be overridden in the backend to possibly implement<br>
faster drawing, but it is already much faster than using <a href="#RendererPS-draw_lines">draw_lines</a>()<br>
by itself.</tt></dd></dl>

<br>
verts are a sequence of polygon vectors, where each polygon<br>
vector is a sequence of x,y tuples of vertices<br>
<br>
facecolors and edgecolors are a sequence of RGBA tuples<br>
linewidths are a sequence of linewidths<br>
antialiaseds are a sequence of 0,1 integers whether to use aa<br>
<br>
If a linewidth is zero or an edgecolor alpha is zero, the<br>
line will be omitted; similarly, the fill will be omitted<br>
if the facecolor alpha is zero.</tt></dd></dl>

<br>
offsets - is a sequence is x,y tuples<br>
transOffset - maps this to display coords<br>

verts - are the vertices of the regular polygon at the origin<br>

sizes are the area of the circle that circumscribes the<br>
polygon in points^2<br>

facecolors and edgecolors are a sequence of RGBA tuples<br>
linewidths are a sequence of linewidths<br>

You need to override this function (unless your backend doesn't have a<br>

Some imaging systems assume some value for pixels per inch.<br>
points to pixels = points * pixels_per_inch/72.0 * dpi/72.0</tt></dd></dl>
