How to set the bbox in a canvas?

------------ meine nicht schöne Lösung:
2 sehr dünne Linien zufügen

sV = path.line(0.0, y0, 0.0, y0 + hauteur)
sH = path.line(0.0, y0, 22.0, y0)
cblanc.stroke(sV, [style.linewidth(0.002)])
cblanc.stroke(sH, [style.linewidth(0.002)])

Hi there,

you cannot set the bbox for a canvas - it is computed automatically from
its contents:

http://pyx.sourceforge.net/manual/canvas.html#canvas.canvas.bbox

It becomes relevant, though, only when you construct a page from the
canvas, which by defaults uses that bbox (possibly enlarged), but you
can tell the page constructor to use any bbox that you like:

http://pyx.sourceforge.net/manual/document.html#class-page

Note that when you write a canvas to a file "directly", the page (and
document) constructor gets called under the hood, and can pass a bbox
argument to the page constructor as described here:

http://pyx.sourceforge.net/manual/canvas.html#canvas.canvas.writeEPSfile

HTH.
Michael
