Private Member Functions

 CC_DECLARE_DYNAMIC (XPFRenderRegion)
 XPFRenderRegion (PluginNativeFilter *pFilter, CapabilityTree *pPlugCaps, CommonTransInfo *pTransInfo=NULL)
 The Scanning Render Regions constructor. This sets all the member vars of the class to default values (usually 0 or NULL).
 ~XPFRenderRegion ()
 Destructor - It will do something if it needs to but at present this function is empty.
virtual BOOL AttachDevice (View *, CNativeDC *, Spread *SpreadToAttach=NULL)
virtual BOOL StartRender ()
 Called to start the rendering process. Allows the render region to get ready to start rendering.
virtual BOOL StopRender ()
 Called to stop rendering.
virtual void DrawPathToOutputDevice (Path *PathToRender, PathShape shapePath=PATHSHAPE_PATH)
 There is no actual rendering, as this class does not actually render anything to a device.
virtual void DrawRect (DocRect *RectToRender)
 There is no actual rendering, as this class does not actually render anything to a device.
virtual void DrawLine (const DocCoord &StartPoint, const DocCoord &EndPoint)
 There is no actual rendering, as this class does not actually render anything to a device.
virtual void DrawPixel (const DocCoord &Point)
 There is no actual rendering, as this class does not actually render anything to a device.
virtual void DrawBitmap (const DocCoord &Point, KernelBitmap *pBitmap)
 There is no actual rendering, as this class does not actually render anything to a device.
virtual void DrawBitmap (const DocCoord &Point, UINT32 BitmapID, UINT32 ToolID=NULL)
 There is no actual rendering, as this class does not actually render anything to a device.
virtual BOOL DrawTransformedBitmap (NodeBitmap *pNodeBitmap)
 Works out if it can draw a Transformed bitmap.
virtual void DrawDragRect (DocRect *RectToRender)
 None - I just had to overide this function as it is pure virtual. Does nothing.
virtual void DrawBlob (DocCoord p, BlobType type)
 None - I just had to overide this function as it is pure virtual. Does nothing.
virtual void DrawCross (const DocCoord &Point, const UINT32 Size)
 None - I just had to overide this function as it is pure virtual. Does nothing.
virtual void DrawBitmapBlob (const DocCoord &Point, KernelBitmap *BlobShape)
 None - I just had to overide this function as it is pure virtual. Does nothing.
virtual void DrawBitmapBlob (const DocCoord &Point, ResourceID resID)
 None - I just had to overide this function as it is pure virtual. Does nothing.
virtual void InitClipping ()
 Sets up the clipping - does nothing in this class.
virtual void InitAttributes ()
 Sets up the attributes. Does nothing in this class.
virtual void SetLineAttributes ()
 Does nothing in this class.
virtual void SetOSDrawingMode ()
 Does nothing in this class.
virtual void SetQualityLevel ()
 Does nothing in this class.
virtual MILLIPOINT CalcPixelWidth ()
 Does nothing in this class.
virtual MILLIPOINT CalcScaledPixelWidth ()
 Does nothing in this class.
virtual double GetPixelsPerInch ()
virtual BOOL CheckOffscreenBounds ()
virtual void GetRenderRegionCaps (RRCaps *pCaps)
 This function allows render regions to admit to what they can and can not render. This allows other areas of the program to come in and help render regions out in some situations, if they are unable to render everything. eg. an OSRenderRegion can not render transparancy.
virtual BOOL RenderPaperAsInk ()
