computeWarpedBBox()

lsst.afw.math._warper.computeWarpedBBox	(		destWcs,
			srcBBox,
			srcWcs )

Compute the bounding box of a warped image.

The bounding box includes all warped pixels and it may be a bit oversize.

Parameters
----------
destWcs : `lsst.afw.geom.SkyWcs`
    WCS of warped exposure
srcBBox : `lsst.geom.Box2I`
    parent bounding box of unwarped image
srcWcs : `lsst.afw.geom.SkyWcs`
    WCS of unwarped image

Returns
-------
destBBox: `lsst.geom.Box2I`
    bounding box of warped exposure
