Synopsis
*DEPRECTATED* Calculate the bounding box of a region.
Syntax
(xmin, ymin, xmax, ymax) = regExtent(reg)
Description
The regExtent routine returns the bounding box of a region. It is primarily useful if you wish to use the six-argument form of regArea().
The region module is not available by default; see "ahelp region" for information on loading the module.
Example
>>> from region import * >>> reg = regParse("ellipse(10,10,4,3,24)-rect(4,2,7,8)") >>> (x0,y0,x1,y1) = regExtent(reg) >>> print("Bounding box is ({0:.1f},{1:.1f}) to ({2:.1f},{3:.1f})".format(x0,y0,x1,y1)) Bounding box is (5.1,5.6) to (14.9,14.4) >>> print(regArea(reg)) 35.0 >>> regArea(reg, 5.1, 5.6, 14.9, 14.1, 1) 35.0 >>> regArea(reg, 5.1, 5.6, 14.9, 14.1, 0.1) 37.700000000000003
