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

Example

// 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;
  ImageEnMView1.MIO.Params[i].JPEG_Quality := 90;
end;
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;
