expandToInclude() [1/2]

void ossimGrect::expandToInclude

(

const ossimGpt &

gpt

)

Expands existing rect to accommodate argument point.

If this object contains NaNs (uninitialized), then the rect is set to 0-area with the arg point as both UL and LR – convenient for establishing bounds in a loop over collection of points. This method does not consider height.

Parameters

gpt	Argument point.
