description: Hi everybody, I am trying to compute the area of this figure with IDLanROI:ComputeGeometry http://juan.gulo.org/area2.png but I obtain a negative area. I have checked it and there is not lines crossing over others. For the "horizontal" part of the figure the line begins and finishes in negative values of "y" (that is, the first and last point), but is it a problem? Ideas? I have been looking at it all the weekend but I don't have any clue about the possible problem.
