ImagemapClickableCircle::ImagemapClickableCircle (  Path *  ppthPath, TCHAR *  pcURL = NULL, TCHAR *  pcFrame = NULL )

Specific constructor. ImagemapClickableCircle::ImagemapClickableCircle(Path* ppthPath, TCHAR* pcURL, TCHAR* pcFrame) : ImagemapClickableArea(pcURL, pcFrame) Author: Graham_Walmsley (Xara Group Ltd) <camelotdev@xara.com> Date: 15/4/97 Definition at line 485 of file clicarea.cpp. : ImagemapClickableArea(pcURL, pcFrame) { //If we have been passed a path if (ppthPath) { //Get its bounding box DocRect rectBounds=ppthPath->GetBoundingRect(); //Then the centre of the circle is the centre of the bounding box m_dcCentre=DocCoord(rectBounds.lo.x/2 + rectBounds.hi.x/2, rectBounds.lo.y/2 + rectBounds.hi.y/2); //And the radius of the circle is half the width of the rectangle m_lRadius=rectBounds.Width()/2; } else { m_dcCentre=DocCoord(0,0); m_lRadius=0; } }

DocRect ImagemapClickableCircle::GetBoundingRect (   )  [virtual]

Gets the bounding rectangle. DocRect ImagemapClickableCircle::GetBoundingRect() Author: Graham_Walmsley (Xara Group Ltd) <camelotdev@xara.com> Date: 1/5/97 - VOTE LABOUR! Parameters: -  [INPUTS] Returns: The bounding rectangle of the circle Implements ImagemapClickableArea. Definition at line 586 of file clicarea.cpp. { return DocRect(m_dcCentre.x-m_lRadius, m_dcCentre.y-m_lRadius, m_dcCentre.x+m_lRadius, m_dcCentre.y+m_lRadius); }

INT32 ImagemapClickableCircle::Write (  CCLexFile *  pfileToWrite = NULL, TCHAR *  pcBuffer = NULL )  [virtual]

Writes this clickable area, in client-side imagemap form, into the buffer or the file or both. INT32 Write(CCLexFile* pfileToWrite=NULL, TCHAR* pcBuffer=NULL) Author: Graham_Walmsley (Xara Group Ltd) <camelotdev@xara.com> Date: 15/4/97 Parameters: pfileToWrite  The file to write to [INPUTS] pcBuffer The text buffer to write to Either of the above may be NULL. Returns: The number of TCHARs written. This function may be called with all parameters NULL, to find out how many TCHARs will be written into the imagemap, and hence to find out how long the text buffer must be Implements ImagemapClickableArea.
