For example, when you add an ellipse to a path, you<br /> specify the upper-left corner, the width, and the height of<br /> the ellipse's bounding rectangle. Those numbers (upper-left<br /> corner, width, and height) are not stored in the path;<br /> instead; the ellipse is converted to a sequence of four<br /> Bézier splines. The path stores the endpoints and control<br /> points of those Bézier splines.<br /> <br /> <br /> <br /> A path stores an array of data points, each of which belongs<br /> to a line or a Bézier spline. If some of the points in the<br /> array belong to Bézier splines, then HasCurve returns TRUE.<br /> If all points in the array belong to lines, then HasCurve<br /> returns FALSE.<br /> <br /> <br /> <br /> Certain methods flatten a path, which means that all the<br /> curves in the path are converted to sequences of lines. After<br /> a path has been flattened, HasCurve will always return FALSE.<br /> Flattening happens when you call the TGPGraphicsPath.Flatten,<br /> TGPGraphicsPath.Widen, or TGPGraphicsPath.Warp method of the<br /> GraphicsPath class.</div>
