Pt2Rect
Pt2Rect Find smallest rectangle enclosing two points void Pt2Rect(pt1, pt2, resultRect ); Point pt1 ; any two . . . Rect * resultRect ; receives coordinates of enclosing rectangle Pt2Rect determines the coordinates of the smallest rectangle that will enclose the pixels represented by two points.
pt1 and . . .
pt2 are any two 4-byte Point structures. resultRect is the address of an 8-byte Rect structure. Upon return it will contain the coordinates of a rectangle that encloses pt1 and pt2 .
Notes: If pt1 or pt2 have the same horizontal or vertical coordinate resultRect
is set to the empty rectangle (0,0)(0,0).
The points may be in any order. The points are stored into the correct part
of the Rect structure; i.e., the highest vertical coordinate of either point is stored as resultRect.top, and so forth.
