SftPrintPreview/DLL 2.0 - Print Preview Control for C/C++

CSftPrintPreview_Main::OnPrintInitialize Function

The OnPrintInitialize virtual override is called to initialize print/preview of one or more pages.

C++

virtual void CSftPrintPreview_Main::OnPrintInitialize(
    CDC* pDC,
    LPSFTPRINTPREVIEW_DRAWINFO lpInfo);

Parameters

pDC

The device context used for page rendering.

lpInfo

A pointer to the SFTPRINTPREVIEW_DRAWINFO structure defining additional information about the current previewing and printing operation.

Comments

The OnPrintInitialize virtual override is called to initialize print/preview of one or more pages. It is called immediately before displaying/printing one or more pages and is followed by one or more calls to OnPrintOnePage and a final call to OnPrintTerminate.

The OnPrintInitialize virtual override is typically used to initialize and allocate resources that are used to render pages.

This function is only used for application-generated output.

Example

C++

void CPreviewPagesView::OnPrintInitialize(CDC* pDC, LPSFTPRINTPREVIEW_DRAWINFO lpInfo)
{
    // 10 point font
    int height = MulDiv(10, GetDeviceCaps(lpInfo->hDCPrinter, LOGPIXELSY), 72);
    m_PrintFont.CreateFont(- height, 0, 0, 0, FW_NORMAL, FALSE, FALSE,
    FALSE, DEFAULT_CHARSET,
    OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS,
    DEFAULT_QUALITY, FF_DONTCARE|DEFAULT_PITCH,
    _T("Arial"));
    _ASSERT(m_PrintFont.m_hObject);
}

void CPreviewPagesView::OnPrintTerminate(CDC* pDC, LPSFTPRINTPREVIEW_DRAWINFO lpInfo)
{
    m_PrintFont.DeleteObject();
}
