RenderDocumentToFile

Rendering and printing

Description

Renders certain pages from the selected document to an image file on disk.

By default rendering uses the GDI+ system which is available by default in Windows XP and later.

Option 10, TIFF (G4) output, is only available on Windows Vista and Windows Server 2008 and later.

It is also possible to render using Cairo, use the SetCairoFileName and SelectRenderer functions.

Syntax

Delphi

function TDebenuPDFLibrary1511.RenderDocumentToFile(DPI: Double; StartPage, EndPage, 
  Options: Integer; FileName: WideString): Integer;

ActiveX

Function DebenuPDFLibrary1511.PDFLibrary::RenderDocumentToFile(DPI As Double,
  StartPage As Long, EndPage As Long, Options As Long,
  FileName As String) As Long

DLL

int DPLRenderDocumentToFile(int InstanceID, double DPI, int StartPage, int EndPage,
  int Options, wchar_t * FileName)

Parameters

DPI The DPI to use for the rendering. A value of 72 will give the same result as Acrobat when the zoom level is 100%.
StartPage The first page to print
EndPage The last page to print
Options 0 = BMP output
1 = JPEG output
2 = WMF output
3 = EMF output
4 = EPS output
5 = PNG output
6 = GIF output
7 = TIFF output
8 = EMF+ output
9 = HTML5 output
10 = G4 TIFF output
FileName The path and filename to use for the file.
Each page will be stored in a separate file.
If this parameter contains "%p" this will be replaced by the page number, otherwise the page number will be appended to the end of the filename before the extension.
For example, if FileName is "output.jpg" and page 10 is rendered the image will be stored in a file called "output10.jpg".
If FileName is "page%poutput.bmp" and page 5 is rendered the image will be stored in a file called "page5output.bmp".

Return values

0 The pages were not rendered successfully. This is usually caused by the StartPage or EndPage parameters being out of range.
1 The pages were rendered successfully
