Modify corner of rectangle

Hi, is it possible to modify corner of rectangle by SKILL? I know just lehimodifycorner command that opens only form for modify corner, but I don't know how to modify corners without this form. Any suggestion? Thank you a lot. Zdeno.

     A rectqangle is represented in the database by its bounding box, two points - lower left and upper right. Once you start modifying the corners, you have to create a polygon. This first involves turning the bounding box into 4 points:

    rectBBox = rectId~>bBox
    pointList = list(
                        car(rectBBox)
                        list( xCoord(car(rectBBox)) yCoord(cadr(rectBBox)))
                        cadr(rectBBox)
                        list(xCoord(cadr(rectBBox)) yCoord(car(rectBBox))))

    Then you manipulate this point list to create the corner modifications and create a new object - a polygon:

     newObj = dbCreatePolygon( cvId list( rectId~>layer rectId~>purpose pointList )

    You may want to copy over all the properties from the rectangle to the polygon.

    Finally delete the rectangle.

    Ted,

    Actually I think he just wants leModifyCorner rather than leHiModifyCorner.

     Thanks Andrew,

    That is a command I did not know. I learn something new every day.

    However, you cannot use leModifyCorner inside of a pcell and have to do it the hard way.

    Thanks you a lot

    I needed function  "leModifyCorner"

        id_rect1 = dbCreateRect(cv_id "Nimp" list(x1:y1 x2:y2))
        leModifyCorner( id_rect1 list(t t t t) nil 20.0 20 )


    Have a nice day.

    Zdeno.
