Purpose |
Retrieve the resolution of the host printer page. |
Syntax |
XPRINT GET PPI TO x&, y& |
Remarks |
XPRINT GET PPI retrieves the resolution (points per inch) of the host printer page. The resolution is always specified in pixels, regardless of any XPRINT SCALE option. If executed without a host printer attached, error 57 is generated, and the values 0,0 are returned. This statement is particularly useful in drawing items such as rulers and graphs to a particular physical size. There are 25.4 millimeters per inch, so just divide by 25.4 to convert from pixels per inch to pixels per millimeter. |
