TIEVisionSearchablePDFGenerator.addPage
Declaration
procedure addPage(image: TIEVisionImage; format: TIEVisionPDFImageFormat = ievPDFImgFmt_AUTO); safecall;
Description
Add a new page (using a source image). OCR is performed immediately, so this is blocking operation.
| Parameter | Description |
| image | Image containing text to be OCR'ed |
| format | Image compression format. Default is ievPDFImgFmt_AUTO |
Note:
◼The PDF page will be created at the size and DPI of the image (i.e.
Width x
Height /
Dpi). You can
set the DPI of the image before
adding the page to scale it
◼PDF parameters are not supported
◼A shortcut method for this is available:
CreateSearchablePDF
// Create a textual PDF named 'out.pdf' from the content of ImageEnMView1 using OCR
pdfGen := IEVisionLib.createSearchablePDFGenerator('./', IEOCRLanguageList[OCR_English_language].Code);
pdfGen.beginDocument(PAnsiChar(AnsiString(langPath + 'out')), PAnsiChar(AnsiString('title')));
for i := 0 to ImageEnMView1.ImageCount - 1 do
begin
ImageEnMView1.SelectedImage := i; // Show the image being processed
pdfGen.addPage(ImageEnMView1.IEBitmap.GetIEVisionImage());
end;
pdfGen.endDocument();
