attribute value.
This item is used to begin the definition of a path. Paths are a collection of
points connected by lines that form opened or closed objects. Multiple
subpaths may be created using SO_CLOSESUBPATH while defining a path. Note that the
current object and group transformations will also apply during creation of a
path. This allows maximum flexibility with transforming paths. Any object can be
rendered to create the path. However, due to current limitations, text objects
will not be added to the path. Multiple levels of paths are also allowed.
SO_ENDPATH
Ends the definition of a path.
dwDataSize must be zero, and
pData must be NULL.
SO_CLOSESUBPATH
Closes the current subpath.
dwDataSize must be zero, and
pData must be NULL.
SO_DRAWPATH
Strokes, fills, or both strokes and fills the current path with the current
pen and brush. Since the group, path, and object transformations were applied
when the path was created, they are not applied again.

sizeof(
WORD), and

value, or both.

attribute value.

SORECT structure that identifies the bounding rectangle of all commands used within
the symbol.
SO_ENDSYMBOL
Ends the definition of a symbol.
dwDataSize must be zero, and

SO_BEGINTEXTFRAME
Starts the definition of a text frame. A text frame is used in conjunction
with SO_TEXTINPARA to wrap text within a frame. Text is wrapped according to the

algorithm.

string that follows.
