Read ContourHeight to obtain the height of a contoured figure.
In zoom mode, if trimmed or pixelated, a contoured figure might differ in height and width from the base width and height. For instance a small, trimmed ellipse might have a contour height of 0, though the real height is 2. Read this property to balance contour height an real height. For instance, in an OnEndDraw event handler:
while DrawObject.ContourHeight = 0
DrawObject.Height := DrawObject.Height + 1; // Force a spatial contour
If the figure i not a contour, TIfgure.Height is returned.
