[OSSIM] Calculation of bounding rects

[William M. <mo...@sp...>]

When I clip a polygon to the current tile bounding rect, and compare the
bounding rect of the clipped polygon to the bounding rect of the tile
itself, the two are not exactly equal.  I converted the tile rect to
ossimGpts:



projTileRect = lineSampleToWorld(theTile->getImageRectangle());

poly.clipToRect( clippedPolyRect, projTileRect );



When I look at the ul points of clippedPolyRect and projTileRect, they are
not exactly equal.  When I open them up in imagelinker, they appear to be
the same.  Any thoughts?



Thank you,
