| class TGopFilledPolygonWithPattern : public TGraphicsOperation |
An accelerated graphics operation that fills a polygon with a pattern held in another bitmap.
AddPoints() must be called to specify the polygon to be filled. Objects of this class can be passed to a graphics accelerator's Operation() function either individually, or in a buffer.

| TGopFilledPolygonWithPattern | ( | TGopFillPattern | aPattern, |
| CGraphicsContext::TFillRule | aFillRule | ||
| ) | [inline] | ||
Constructor with a fill pattern and a fill rule. The number of points is initialised to zero.
| TGopFillPattern aPattern | The fill pattern. |
| CGraphicsContext::TFillRule aFillRule | Bit flags for how self-crossing polygons are filled. |
| void | AddPoints | ( | TInt | aNumPoints, |
| TPoint * | aPoints | |||
| ) | [inline] | |||
Specifies the polygon to be filled as a number of 2D point coordinates.
AddPoints() should only be called once the TGopFilledPolygonWithPattern object has been stored into a buffer. There must be enough room in the buffer after the TGopFilledPolygonWithPattern object to hold aNumPoints TPoint sized structures. This is because the points are copied into the memory space directly following the TGopFilledPolygonWithPattern object.
| CGraphicsContext::TFillRule | iFillRule |
Bit flags for how self-crossing polygons are filled.
| TGopFillPattern | iPattern |
The pattern of bitmaps that is used to fill the polygon.
