pageMargins(lft: Integer; rght: Integer; tp: Integer; btm: Integer);
The pageMargins method of the JadeRichText class specifies the left, right, top, and bottom margins, respectively, around a rich text control on a printed page. Specify the parameter values as twentieths of a point (twip), which is 1/1440th of an inch (that is, there are 1440 twips in an inch).
All margins are half an inch (720 twips) by default. Although you can set a margin as small as zero (0) twips, the actual margin can be no smaller than that used by the printer to which the control is output.
