The DrvStrokeAndFillPath function strokes (outlines) and fills a path concurrently.
BOOL DrvStrokeAndFillPath( _Inout_ SURFOBJ *pso, _Inout_ PATHOBJ *ppo, _In_ CLIPOBJ *pco, _In_opt_ XFORMOBJ *pxo, _In_ BRUSHOBJ *pboStroke, _In_ LINEATTRS *plineattrs, _In_ BRUSHOBJ *pboFill, _In_ POINTL *pptlBrushOrg, _In_ MIX mixFill, _In_ FLONG flOptions );
- pso [in, out]
Pointer to a SURFOBJ structure that describes the surface on which to draw.
- ppo [in, out]
Pointer to a PATHOBJ structure that describes the path to be filled. The PATHOBJ_Xxx service routines are provided to enumerate the lines, Bezier curves, and other data that make up the path.
- pco [in]
- pxo [in, optional]
Pointer to a XFORMOBJ structure that is required when a geometric wide line is drawn. It specifies the transform that takes world coordinates to device coordinates. This is needed because the path is provided in device coordinates but a geometric wide line is actually widened in world coordinates. The XFORMOBJ can be queried to find out what the transform is.
- pboStroke [in]
Pointer to a BRUSHOBJ structure that specifies the brush to use when stroking the path.
- plineattrs [in]
Pointer to the LINEATTRS structure that describes the attributes of the line to be drawn.
- pboFill [in]
Pointer to a BRUSHOBJ structure that specifies the brush to use when filling the path.
- pptlBrushOrg [in]
Pointer to a POINTL structure that specifies the brush origin for both brushes.
- mixFill [in]
The mix mode that defines the foreground and background raster operations to use for the brush. For more information about mix mode, see Remarks.
- flOptions [in]
Specifies either FP_WINDINGMODE, meaning that a winding mode fill should be performed, or FP_ALTERNATEMODE, meaning that an alternating mode fill should be performed. All other flags should be ignored. For more information about these modes, see Path Fill Modes.
The return value is TRUE if the driver is able to fill the path. Otherwise, if GDI should instead fill the path, the return value is FALSE. If an error occurs, the return value is DDI_ERROR, and an error code is logged.
If a wide line is used for stroking, the filled area must be reduced to compensate.
The driver can return FALSE if the path or the clipping is too complex for the device to handle; in that case, GDI converts to a simpler call. For example, if the device driver has set the GCAPS_BEZIERS flag in the flGraphicsCaps member of the DEVINFO structure and then receives a path with Bezier curves, it can return FALSE; GDI will then convert the Bezier curves to lines and call DrvStrokeAndFillPath again. If the device driver returns FALSE again, GDI will further simplify the call, making calls to DrvStrokePath and DrvFillPath, or to DrvBitBlt, depending on the mix and width of the lines making up the path.
The mix mode defines how the incoming pattern should be mixed with the data that is already on the device surface. The MIX data type consists of two binary raster operation (ROP2) values packed into a single ULONG. The lowest-order byte defines the foreground raster operation; the next byte defines the background raster operation. For more information about raster operation codes, see the Microsoft Windows SDK documentation.
