Thus a translation of the origin to the point (-
rect.x,-rect.y
) does the trick.
We have the sketch in the right place on the page, but it won't necessarily fit into the space available on
the paper. We must scale the sketch so that it doesn't hang out beyond the right side or below the
bottom of the printable page area.
Scaling the Sketch to Fit
We saw earlier that we can get the width and height of the printable area on a page by calling the
getImageableWidth()
and
getImageableHeight()
methods for the
PageFormat
object that is
passed to the
print()
method. We also have the width and height of the rectangle that encloses the
entire sketch. This gives the information that we need to scale the sketch to fit on the page. There are a
couple of tricky aspects that we need to think about though.
