NAME    [Toc]    [Back]

     fudge - specifies fudge values that are added to a	graphics window

C SPECIFICATION    [Toc]    [Back]

     void fudge(xfudge,	yfudge)
     long xfudge, yfudge;

PARAMETERS    [Toc]    [Back]

     xfudge   expects the number of pixels added in the	x direction.

     yfudge   expects the number of pixels added in the	y direction.

DESCRIPTION    [Toc]    [Back]

     fudge specifies fudge values that are added to the	dimensions of a
     graphics window when it is	sized.	Typically, you use it to create
     interior window borders.  Call fudge prior	to calling winopen.

     fudge is useful in	conjunction with stepunit and keepaspect.  With
     stepunit the window size for integers m and n is:

	  width	= xunit	* m + xfudge
	  height = yunit * n + yfudge

     With keepaspect the window	size is	(width,	height), where:

	  (width - xfudge) * yaspect = (height - yfudge) * xaspect

SEE ALSO    [Toc]    [Back]

     keepaspect, stepunit, winopen
