Errata Release Notes

• The following release note was missing in HALCON 18.11 Progress:
  HDevelop has been internally upgraded to use HALCON’s visualization and interaction mechanisms, so-called drawing objects or draw operators. This makes the visualization in HDevelop more consistent to the experience after exporting code to native languages.
  This affected also the compatibility. In particular, the following visualization and interaction operators are not working with Graphics Windows opened using dev_open_window: draw_nurbs, draw_nurbs_interp, draw_nurbs_interp_mod, draw_nurbs_mod, drag_region1, drag_region2, drag_region3, get_mshape, get_os_window_handle, get_window_pointer3, read_string, set_mshape, slide_image, and query_mshape. In case such an operator is necessary, opening a HALCON window using open_window is recommended. Additionally, the behavior of get_mposition has been changed: If a mouse button is pressed outside a Graphics Window that was opened with dev_open_window, no valid position will be returned by get_mposition untill the mouse button is released again. If the mouse button was pressed inside the Graphics Window, however, entering and leaving the window is recognized and the mouse position and state are returned as in earlier versions.
• The following Release Note was missing in HALCON 18.05 Progress:
  The introduction of the reference manual chapter Morphology / Gray Values has been extended with more detailed descriptions regarding gray value morphology operations.
