Hello everybody!

I want to use quickPDF as a viewer in my C++ application, and moreover I need to render to the pdf content to a DC.
I had a look to windows MFC classes, but I do not know exactly which type of DC is supported.

Can somebody give me more details about how to render the PDF to a DC, or point me to some tutorials?

Thanks in advance,|
D.M.

Hi D.M.

Try something like this ...

________________

BOOL CPDFViewerDlg::OnInitDialog()

{

http://msdn.microsoft.com/en-us/library/fwz35s59%28VS.80%29.aspx - CDialog:: - MFC)

// Draw updated page

m_iDAFileHandle = m_QP.DAOpenFile(m_strFile, CString(_T("")));

m_iPageRef = m_QP.DAFindPage(m_iDAFileHandle, 1);

// Resize window based on new PDF

MoveWindow(0, 0, m_QP.DAGetPageWidth(m_iDAFileHandle, m_iPageRef),

m_QP.DAGetPageHeight(m_iDAFileHandle, m_iPageRef),TRUE);

// Set the dialog title

CString strTitle;

::GetFileTitle(m_strFile, strTitle.GetBufferSetLength(1024), 1024);

strTitle.ReleaseBuffer();

// Recenter the dialog in the center of the active window

CenterWindow(GetDesktopWindow());

return TRUE; // return TRUE unless you set the focus to a control

// EXCEPTION: OCX Property Pages should return FALSE

}

void CPDFViewerDlg::OnPaint()

{

CPaintDC dc(this);

m_QP.DARenderPageToDC(m_iDAFileHandle, m_iPageRef, 72,(int) (HDC) dc);

}

Thank you so much !
It really worked!

I would like to move from MFC to GTK . Is it possible to render it in a GTK DC too?

Best wishes,
D.M.

Just in case somebody will need the answer of my question ... here it is:

Yes, quickPDF can be used to render even to GTK device content.

<code>

HWND m_hwnd = HWND(GDK_WINDOW_HWND(this->m_drawingArea.get_window()>gobj() ));
HDC m_hdc = GetDC(m_hwnd);
QP.RenderPageToDC(100, 1,(int)(HDC) m_hdc);
