Thread: [matplotlib-devel] One short question

In the Non-PostScript font classes in mathtext.py the set_canvas_size is
def set_canvas_size(self, w, h):
 'Dimension the drawing canvas; may be a noop'
 self.width = int(w)
 self.height = int(h)
 for font in self.fonts.values():
 font.set_bitmap_size(int(w), int(h))
While in the PS class:
 def set_canvas_size(self, w, h, pswriter):
 'Dimension the drawing canvas; may be a noop'
 self.width = w
 self.height = h
 self.pswriter = pswriter
Why is the float converted to int in the first case, and not in the second?
