The main intention in creating this resource +is to allow a global sharable image resource (RSgImage) to be used as a target of +DirectGDI rendering. For example, in a DirectGDI adaptation where OpenVG is used to +implement DirectGDI functionality, the creation of RDirectGdiImageTarget may be associated +with the creation of an underlying EGL surface from the given RSgImage. This handle class +and its DirectGDI adaptation-specific resource are non-sharable and local within the +creating thread. + +This class is part of a generic layer and will forward any request to the CDirectGdiDriver +singleton for the calling thread. + +CDirectGdiContext is activated on an RDirectGdiImageTarget. This causes all subsequent +context drawing operations to to draw to the image resource referred to by the +RDirectGdiImageTarget. + +@see CDirectGdiContext +*/ +NONSHARABLE_CLASS(RDirectGdiImageTarget) + { + friend class CDirectGdiDriver; + friend class CTPanicTests; + +public: + IMPORT_C RDirectGdiImageTarget(); + IMPORT_C RDirectGdiImageTarget(CDirectGdiDriver& aDriver); + IMPORT_C TInt Create(const RSgImage& aImage); + IMPORT_C void Close(); + inline TInt Handle() const; + +private: + CDirectGdiDriver* iDriver; + TInt iHandle; + }; + +#include + +#endif //DIRECTGDIIMAGETARGET_H
