typedef struct _PATHDATA {
FLONG flags;
ULONG count;
POINTFX pptfx;
} PATHDATA, *PPATHDATA;
The PATHDATA structure describes all or part of a subpath.
For example, a MoveTo call by an application within a path begins a new subpath.
Members
flags
Flags describing the data returned are defined as follows:
| Value | Meaning |
| PD_BEGINSUBPATH | The first point begins a new subpath. It is not connected to the previous subpath. If this flag is not set, the starting point for the first curve to be drawn from this data is the last point returned in the previous call. |
| PD_ENDSUBPATH | The last point in the array ends the subpath. This subpath can be open or closed depending on the PD_CLOSEFIGURE flag. If there is more data to be returned in the path, the next record begins a new subpath. Note that a single record might begin and end a subpath. |
| PD_RESETSTYLE | This bit is defined only if this record begins a new subpath. If set, it indicates the style state should be reset to zero at the beginning of the subpath. If not set, the style state is defined by the LINEATTRS structure, or continues from the previous subpath. |
| PD_CLOSEFIGURE | This bit is only defined if the record ends a subpath. If set, there is an implicit line segment connecting the last point of the subpath with the first point. If such a closed subpath is being stroked, joins are used all around the path, and there are no end caps. If this flag is not set, the subpath is considered open, even if the first and last points happen to coincide. In that case, end caps should be drawn. This flag is not relevant to filling because all subpaths are assumed closed when a path is filled. |
| PD_BEZIERS | If set, each set of three control points returned for this call describes a Bezier curve. If clear, each control point describes a line segment. A starting point for either type is either explicit at the beginning of the subpath, or implicit as the endpoint of the previous curve. |
count
Specifies the count of POINTFX structures pointed to by pptfx.
pptfx
Points to an array of POINTFX structures that define the control points for the curves. These structures must not be modified.
