Description

draw_xld_moddraw_xld_modDrawXldModDrawXldModDrawXldModdraw_xld_mod returns a contour, which has been interactively modified by the user in the window.

You can modify the contour in two ways: by editing the contour itself, e.g., by inserting or moving contour points, or by transforming the contour as a whole, e.g., by rotating moving or scaling it. Note that you can only edit a contour if EditEditEditEditeditedit is set to 'true'"true""true""true""true""true". Similarly, you can only rotate, move or scale it if RotateRotateRotateRotaterotaterotate, MoveMoveMoveMovemovemove, and ScaleScaleScaleScalescalescale, respectively, are set to 'true'"true""true""true""true""true".

draw_xld_moddraw_xld_modDrawXldModDrawXldModDrawXldModdraw_xld_mod starts in the transformation mode. In this mode, the contour is displayed together with 3 symbols: 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". To switch into the edit mode, press the Shift key; by pressing it again, you can switch back into the transformation mode.

Transformation Mode

Edit Mode In this mode, the contour is display together with 5 pick points, which are located in the middle and at the corners of the surrounding rectangle. If the contour is closed, the pick points are displayed as squares, otherwise shaped like a 'u'. By clicking on a pick point, you can close an open contour and vice versa. Depending on the state of the contour, you can perform different modifications. Open contours (pick points shaped like a 'u')

Closed contours (square pick points)

Pressing the right mouse button terminates the procedure. On macOS draw_xld_moddraw_xld_modDrawXldModDrawXldModDrawXldModdraw_xld_mod can also be terminated by pressing the escape key.

Attention

If used in a buffer window, mouse events have to be supplied by the application, while the draw operator must be run in another thread.

Result

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