toRect()

bool ossimDrect::toRect

(

const ossimString &

rectString

)

expected Format: form 1: ( 30, -90, 512, 512, [LH|RH] ) -x- -y- -w- -h- -Right or left handed-

form 2: ( 30, -90, 512, 512) -x- -y- -w- -h-

NOTE: Form 2 assumes Left handed were x,y is origin upper left and y positive down.

This method starts by doing a "makeNan" on rect.

Parameters

rectString

String to initialize from.

Returns

true or false to indicate successful parsing.

toString()
