Kommentarer

Klassen Margins används för att ändra bredden på marginalerna i PageSettings och PrintController. MarginsConverter är typbeskrivningen för den här klassen.

Left, Right, Top, och Bottom är egenskaper som definierar marginalerna. Clone skapar en identisk Margins. Equals avgör om ett annat objekt har samma dimensioner som en Margins.

Mer information om utskrift finns i översikten över System.Drawing.Printing namnområdet.
