### GreModifyPath Parameter - cmdMode

cmdMode (LONG) - input Modify mode.

The only valid flag is:

MPATH_STROKE This replaces the original path (with a path that encloses the shape produced by stroking the original path) using the current geometric wide line attribute. Any open figures within the path are not closed.

The envelope includes the effects of "line joins" and "line ends" according to the current values of these attributes. For example, where a line joins an arc, the common point is handled according to the line join attribute in the current line attribute bundle. (See Line Attributes.) When a figure is closed by using GreCloseFigure, the line join attribute in the current line bundle is applied to the start and end points. The envelope takes account of any crossings. For example, a stroked X does not have a hole in the middle if it is subsequently drawn in Exclusive-OR mode.
