Declaration
procedure SaveToPDF();
Description
Saves the current image to the active Adobe PDF file, opened using
CreatePDFFile. If your image contains
layers, then the layers will be output as scalable PDF objects.
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 following
TIELayer features are not supported when exporting to PDF:
◼Gradient fills
◼Mask layersThe engine used to save PDF files (either using
PDFium or ImageEn native code) is specified by
PDFEngine.
Note:
◼Images in the PDF file will be aligned to the upper-left corner of the page
◼To abort while saving set
Aborting to true

Example 1
IEGlobalSettings().PDFEngine := ieenNative;
ImageEnView1.IO.CreatePDFFile( 'D:\output.pdf' );
// load and save page 1
ImageEnView1.IO.LoadFromFile('C:\page1.tiff');
ImageEnView1.IO.Params.PDF_Compression := ioPDF_G4FAX; // G4Fax compression
ImageEnView1.IO.SaveToPDF();
// load and save page 2
ImageEnView1.IO.LoadFromFile('C:\page2.tiff');
ImageEnView1.IO.Params.PDF_Compression := ioPDF_G4FAX; // G4Fax compression
ImageEnView1.IO.SaveToPDF();
...Other pages...
// Close PDF file
ImageEnView1.IO.ClosePDFFile();
Example 2
// Create a scalable PDF document containing ten pages with text and a shape
ImageEnView1.IO.CreatePDFFile( 'D:\Explosion.pdf' );
For I := 1 to 10 do
begin
ImageEnView1.Blank;
// Add a yellow explosion shape layer at size 220 x 120
ImageEnView1.LayersAdd( iesExplosion, 50, 50, 220, 120 );
ImageEnView1.CurrentLayer.FillColor := clYellow;
ImageEnView1.CurrentLayer.BorderWidth := 0;
// Add a text layer
ImageEnView1.LayersAdd( ielkText );
ImageEnView1.LayersAdd( 'Explosion on page ' + IntToStr( I ), 25, clRed, 'Arial Black', [fsBold] );
ImageEnView1.CurrentLayer.PosX := IELayer_Pos_HCenter;
ImageEnView1.CurrentLayer.PosY := IELayer_Pos_VCenter;
ImageEnView1.Update();
// Add as a page
ImageEnView1.IO.SaveToPDF();
end;
// Close PDF file
ImageEnView1.IO.ClosePDFFile();
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;
