| TGraphicsOperation:TGopFunction | |
An accelerated graphics operation that fills a polygon with a colour.
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.
How a graphics accelerator can fill polygons is given by TGraphicsAcceleratorCaps::iPolygon.

| CGraphicsContext::TFillRule | iFillRule |
Bit flags for how self-crossing polygons are filled.

| TGopFilledPolygon | ( | TRgb | aColor, |
| CGraphicsContext::TFillRule | aFillRule | ||
| ) | [inline] | ||
Constructor with a fill rule and a fill colour. The number of points is initialised to zero.
| Parameter | Description |
|---|---|
| aColor | The fill colour. |
| aFillRule | Bit flags for how self-crossing polygons are filled. |
Specifies the polygon to be filled as a number of 2D point coordinates.
AddPoints() should only be called once the TGopFilledPolygon object has been stored into a buffer. There must be enough room in the buffer after the TGopFilledPolygon object to hold aNumPoints TPoint sized structures. This is because the points are copied into the memory space directly following the TGopFilledPolygon object.
| Parameter | Description |
|---|---|
| aNumPoints | The number of points in the polygon. |
| aPoints | Pointer to the first point in the polygon. |
