BitmapDriver objects are intended for use when a BBitmap is created with the ability to accept child views. It also adds one significant function over regular DisplayDriver child classes - SetTarget. There is also no option for input server emulation, for obvious reasons. Cursor functions are redefined to do absolutely nothing Usage: Allocate and call SetTarget on the desired ServerBitmap and start calling graphics methods. All ServerBitmap memory belongs to the BitmapManager. */ class BitmapDriver : public DisplayDriver { public: BitmapDriver(void); ~BitmapDriver(void); bool Initialize(void); void Shutdown(void); void SetTarget(ServerBitmap *target); ServerBitmap *GetTarget(void) const { return _target; } // Settings functions virtual void CopyBits(BRect src, BRect dest); virtual void DrawBitmap(ServerBitmap *bmp, BRect src, BRect dest, LayerData *d); // virtual void DrawPicture(SPicture *pic, BPoint pt); virtual void DrawString(const char *string, int32 length, BPoint pt, LayerData *d, escapement_delta *delta=NULL); virtual void FillArc(BRect r, float angle, float span, LayerData *d, const Pattern &pat); virtual void FillBezier(BPoint *pts, LayerData *d, const Pattern &pat); virtual void FillEllipse(BRect r, LayerData *d, const Pattern &pat); // virtual void FillPolygon(BPoint *ptlist, int32 numpts, BRect rect, LayerData *d, const Pattern &pat); virtual void FillRect(BRect r, LayerData *d, const Pattern &pat); virtual void FillRoundRect(BRect r, float xrad, float yrad, LayerData *d, const Pattern &pat); // virtual void FillShape(SShape *sh, LayerData *d, const Pattern &pat); virtual void FillTriangle(BPoint *pts, BRect r, LayerData *d, const Pattern &pat); virtual void HideCursor(void); virtual void MoveCursorTo(float x, float y); virtual void InvertRect(BRect r); virtual void ShowCursor(void); virtual void ObscureCursor(void); virtual void SetCursor(ServerCursor *cursor); virtual void StrokeArc(BRect r, float angle, float span, LayerData *d, const Pattern &pat); virtual void StrokeBezier(BPoint *pts, LayerData *d, const Pattern &pat); virtual void StrokeEllipse(BRect r, LayerData *d, const Pattern &pat); virtual void StrokeLine(BPoint start, BPoint end, LayerData *d, const Pattern &pat); virtual void StrokePolygon(BPoint *ptlist, int32 numpts, BRect rect, LayerData *d, const Pattern &pat, bool is_closed=true); virtual void StrokeRect(BRect r, LayerData *d, const Pattern &pat); virtual void StrokeRoundRect(BRect r, float xrad, float yrad, LayerData *d, const Pattern &pat); // virtual void StrokeShape(SShape *sh, LayerData *d, const Pattern &pat); virtual void StrokeTriangle(BPoint *pts, BRect r, LayerData *d, const Pattern &pat); // virtual void StrokeLineArray(BPoint *pts, int32 numlines, RGBColor *colors, LayerData *d); virtual void SetMode(int32 mode); float StringWidth(const char *string, int32 length, LayerData *d); float StringHeight(const char *string, int32 length, LayerData *d); // virtual bool DumpToFile(const char *path); protected: void BlitMono2RGB32(FT_Bitmap *src, BPoint pt, LayerData *d); void BlitGray2RGB32(FT_Bitmap *src, BPoint pt, LayerData *d); void BlitBitmap(ServerBitmap *sourcebmp, BRect sourcerect, BRect destrect, drawing_mode mode=B_OP_COPY); void ExtractToBitmap(ServerBitmap *destbmp, BRect destrect, BRect sourcerect); void SetPixelPattern(int x, int y, uint8 *pattern, uint8 patternindex); void Line(BPoint start, BPoint end, LayerData *d, const Pattern &pat); void HLine(int32 x1, int32 x2, int32 y, RGBColor color); void HLineThick(int32 x1, int32 x2, int32 y, int32 thick, PatternHandler *pat); rgb_color GetBlitColor(rgb_color src, rgb_color dest, LayerData *d, bool use_high=true); void SetPixel(int x, int y, RGBColor col); void SetPixel32(int x, int y, rgb_color col); void SetPixel16(int x, int y, uint16 col); void SetPixel8(int x, int y, uint8 col); void SetThickPixel(int x, int y, int thick, RGBColor col); void SetThickPixel32(int x, int y, int thick, rgb_color col); void SetThickPixel16(int x, int y, int thick, uint16 col); void SetThickPixel8(int x, int y, int thick, uint8 col); ServerBitmap *_target; }; #endif
