draw_xlddraw_xldDrawXlddraw_xldDrawXldDrawXld returns a contour, which has been created interactively by the user in the window.

Directly after calling draw_xlddraw_xldDrawXlddraw_xldDrawXldDrawXld you can add contour points by clicking with the left mouse button in the window at the desired positions. You delete the point appended last by pressing the Ctrl key. As soon as you add three contour points, 5 so-called pick points are displayed, one in the middle and 4 at the corners of the surrounding rectangle. By clicking on a pick point you can close the contour or open it again. If the contour is closed, the pick points are displayed in form of squares, otherwise they are shaped like a 'u'.

If the contour is closed you can

By pressing the Shift key, you can switch into the transformation mode. In this mode you can rotate, move, and scale the contour as a whole, but only if you set the parameters RotateRotateRotateRotateRotaterotate, MoveMoveMoveMoveMovemove, and ScaleScaleScaleScaleScalescale, respectively, to 'true'"true""true""true""true""true". Instead of the pick points, 3 symbols are displayed with the contour: a cross in the middle and an arrow to the right if RotateRotateRotateRotateRotaterotate is set to 'true'"true""true""true""true""true", and a double-headed arrow to the upper right if ScaleScaleScaleScaleScalescale is set to 'true'"true""true""true""true""true".

You can

Pressing the right mouse button terminates the procedure. On OS X draw_xlddraw_xldDrawXlddraw_xldDrawXldDrawXld can also be terminated by pressing the escape key.

draw_xlddraw_xldDrawXlddraw_xldDrawXldDrawXld returns 2 (H_MSG_TRUE), if the window is valid and the needed drawing mode (see set_insertset_insertSetInsertset_insertSetInsertSetInsert) is available. If necessary, an exception is raised.
