Previewing a PDF before Saving?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi - 
I'm sure this question will reveal my newbie credentials - but here goes.

I'm going to use QuickPDF as my "printing engine". So instead of writing two routine, one to export to a PDF file, and the other to print to a printer, I'm going to write the PDF export then do a shell command to print it when necessary.

The one obstacle is print preview. 

What's the best way to show the PDF file? 

Can I create it in memory and somehow show it on a canvas (which would be wonderful!). 

Or do I have to save it to disk and then re-open it to preview?

All help appreciated,

Steve

	You can use Debenu Viewer or using QuickPDF RenderPageToDC here is example in AutoIt Func _QP_Display($oQP, $iLeft, $iTop, $iWidth, $iSelectPage = 1) If Not IsObj($oQP) Then ; TODO Else ; select Page $oQP.SelectPage($iSelectPage); $oQP.CombineContentStreams() $oQP.SelectContentStream(1) ; calculate DPI Local $iPageWidth = $oQP.PageWidth(); Local $iPageHeight = $oQP.PageHeight(); Local $iDisplayDPI = ($iWidth / $iPageWidth) * 72 ; create GUI Local $iHeight = ($iWidth * $iPageHeight) / $iPageWidth Local $hwnd = GUICreate('QuickPDF Test Display', $iWidth, $iHeight, $iLeft, $iTop) GUISetState(@SW_SHOW) Local $hDC = _WinAPI_GetDC($hwnd) ; render QP object to Device Context $oQP.RenderPageToDC($iDisplayDPI, $iSelectPage, $hDC); While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE ExitLoop EndSwitch WEnd _WinAPI_ReleaseDC($hwnd, $hDC) GUIDelete($hwnd) ; Deletes a GUI window and all controls that it contains. EndIf EndFunc ;==>_QP_Display Edited by mLipok - 08 Oct 14 at 3:16PM
