Constructor & Destructor Documentation

GRenderClickColourNoPaper::GRenderClickColourNoPaper (  DocRect  ClipRegion, Matrix  ConvertMatrix, FIXED16  ViewScale, UINT32  Depth, double  dpi )

Constructor. Most important jobs are to set the VeryMono flag to FALSE, and to set m_DoCompression = TRUE to ensure correct handling of transparencies. Author: Phil_Martin (Xara Group Ltd) <camelotdev@xara.com> Date: 17/03/2004 Parameters: A  clip region, conversion matrix, scale and bitmap depth. [INPUTS] None  [OUTPUTS] Returns: None Do not call directly, use OSRenderBitmap::Create Definition at line 183 of file grndclik.cpp. : GRenderClickColour(ClipRegion, ConvertMatrix, ViewScale, Depth, dpi) { RenderFlags.VeryMono = FALSE; // simple black&white rendering NOT !!!!! RenderFlags.HitDetect = TRUE; m_DoCompression = TRUE; ClearOnStart = FALSE; }

GRenderClickColourNoPaper::~GRenderClickColourNoPaper (   )

Destructor. Simple cleanup, which involves calling our base classes. Author: Phil_Martin (Xara Group Ltd) <camelotdev@xara.com> Date: 17/03/2004 Definition at line 248 of file grndclik.cpp. : ~GRenderClick() { }

Member Function Documentation

BOOL GRenderClickColourNoPaper::AttachDevice (  View *  pView, wxDC *  DCToAttach, Spread *  SpreadToAttach = NULL, bool  fOwned = false )  [private, virtual]

Most work done in base class, except for the creation of a CCDC member. Author: Chris_Snook (Xara Group Ltd) <camelotdev@xara.com> Date: 27/10/99 Parameters: pView  is used for debug purposes only. DCToAttach is used as a [INPUTS] reference when making the bitmap. Returns: FALSE if failed (no mem for bitmap or CCDC), TRUE if OK Reimplemented from GRenderClickColour. Definition at line 707 of file grndclik.cpp. { // call base class first if (!GRenderDIB::AttachDevice(pView, DCToAttach, SpreadToAttach, fOwned)) return FALSE; /* // now replace the usual RenderDC with our new one. This makes the type of the CCDC // correct, so Quality rendering works correctly, for example. TRY { // IMPORTANT: we 'borrow' the HDC from DCToAttach. We must take care when // deleting this not to delete the HDCs (see the constructor). RenderDC = new CCDC( DCToAttach, RENDERTYPE_HITDETECT ); } CATCH (CMemoryException, e) { // Ooer - not enough memory TRACEALL( _T("No memory for CCDC in GRenderClickColour::AttachDevice") ); return FALSE; } END_CATCH */ RenderDC = new wxBufferedDC() ; m_fOwned = true; return TRUE; }
