Detailed Description

Print preview dialog.

It is intended for displaying grid contents in the way they are printed. This dialogue enables visual display of up to three pages with grid contents and size customization. Grid contents can also be scaled while being displayed on the printer. It is possible to set scale by means of PrinterZoom enumeration or by directly calling SetPrinterZoom() function with transfering it double type parameter. When the given parameter equals 1, scaling is not applied. Besides, the dialogue gives the opportunity of adjusting the printer before printing, choosing paper type and image type and can also be used to start printing.
