An optional object that specifies the area to print, in the following format:

The coordinates you specify for

You must provide all four coordinates. The width (
each be greater than 0.
Points are print units of measurement, and pixels are screen units of measurement; points are a
fixed physical size (1/72 inch), but the size of a pixel depends on the resolution of the particular
screen. You can use the following equivalencies to convert inches or centimeters to twips or points
(a twip is 1/20 of a point):
•
1 point = 1/72 inch = 20 twips
•
1 inch = 72 points = 1440 twips
•
1 cm = 567 twips
You can't reliably convert between pixels and points; the conversion rate depends on the screen
and its resolution. If the screen is set to display 72 pixels per inch, for example, one point is equal
to one pixel.
