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

Since the group, path, and object transformations were applied when the path was created, they are not applied again. dwDataSize must be sizeof(WORD), and pData must be the address of a variable containing the SODP_STROKE or SODP_FILL value, or both.
SO_BEGINGROUP

SO_ENDSYMBOL
Ends the definition of a symbol. dwDataSize must be zero, and pData must be NULL.

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 SO_PARAINDENTS vector attribute value. Symbols are included in the wrapping algorithm. dwDataSize must be sizeof(SORECT), and pData must be the address of a SORECT structure that identifies the bounding rectangle of the text frame.
SO_ENDTEXTFRAME
Ends the definition of a text frame. dwDataSize must be zero, and pData must be NULL.
SO_TEXTINPARA
Draws the text string in the current font and text attributes at the current wrap location. The wrap location is moved by the text extent. Any words that would extend beyond the right indent of the frame are wrapped. This object is only valid within a text frame. dwDataSize must be sizeof(INT) added to the length of the text string, and pData must be the address of a integer variable containing the size of the text string that follows.
