TImageEnMIO.SaveToFilePDF

Declaration

procedure SaveToFilePDF(const FileName: string; SelectedOnly: Boolean = False);

Description

Creates a multipage Adobe PDF file with all images in the attached TImageEnMView or TIEMultiBitmap.
If SelectedOnly = True and the component is attached to a TImageEnMView then only the selected images are output.
The size of the page will be specified by PDF_PaperWidth and PDF_PaperHeight. Margins are specified by PDF_PageMargin.
Image position and size is affected by PDF_ImageOptions.


The engine used to save PDF files (either using PDFium or ImageEn native code) is specified by PDFEngine.

Note:
◼If an internal save error is encountered Aborting will return True. Saving issues due to insufficient write permissions and disk write failures will raise an exception.
◼To abort while saving set Aborting to True

Examples

// Load a multipage TIFF and save it as a PDF file
ImageEnMView.MIO.LoadFromFile('C:\multipage.tiff');
ImageEnMView.MIO.SaveToFilePDF('D:\output.pdf');


// Save multi-frame image in TImageEnMView as PDF with "US Letter" paper size
ImageEnMView.MIO.LoadFromFile('C:\multipage.tiff');
for i := 0 to ImageEnMView1.MIO.ParamsCount - 1 do
begin
  ImageEnMView1.MIO.Params[i].PDF_PaperSize   := iepLetter;
  ImageEnMView1.MIO.Params[i].PDF_Compression := ioPDF_JPEG; // or ioPDF_G4Fax for monochrome images
  ImageEnMView1.MIO.Params[i].JPEG_Quality    := 90;
end;
IEGlobalSettings().PDFEngine := ieenNative;                  // For compression support
ImageEnMView1.MIO.SaveToFilePDF('D:\output.pdf');

Compatibility Information

Prior to v13.2.0, ImageEn would always use native code to save PDF files. From v13.2.0, the saving engine is controlled by PDFEngine. If the PDFium DLL (iepdf*.dll) is located in the EXE folder, ImageEn will now default to using PDFium for saving. To avoid this, set IEGlobalSettings().PDFEngine := ieenNative;
