Element: graphic_window.full_erase
Element: graphic_window.full_erasenumeric
The erase mode for graphic_window. This determines how the window is repaired when entities displayed within it are removed or modified. There are two modes possible:
0 - The quick and nasty mode. In this mode the outline of the entity being erased is drawn using the background color or image. Consequently any entity graphics which were previously hidden by the entity will not be repainted properly.
1 - The full method. In this mode the window rectangle occupied by the entity being erased is completely repaired and any entities previously obscured get displayed properly.
Although the most satisfying method is the full method (1), the repairing of the window can be time consuming if the window has a long display list of complex entities, particularly instances, to traverse. For simple entity configurations, the full method is usually acceptable. For complex configurations use method 0 unless image integrity is paramount.
New graphic windows have an erase mode of 0.
