picturebox[baseline] picturebox[baseline] (p1)(p2)
The first form of picturebox
causes a scalar baseline
fraction to be emitted in the pspicture
environment of the output. See
PSTricks
documentation for pspicture
.
In the second form, the baseline fraction is optional, and the
two points that follow define the diagonal of a three-dimensional
bounding box
for the completed scene. The parallel projection
of the bounding box
determines the corners of the drawing's pspicture*
environment,
which is used in place of pspicture
. This causes PostScript to
clip
the final drawing to the bounding box in 2d. If there is a
camera
specified, the camera tranformation is applied to the
bounding box, and the pspicture
is set just large
enough to include the transformed box.
When no bounding box is given, sketch
computes one
automatically.
