Faster way to build a PDF from image files

[ddi development b.v.]

Hi,

I need to create a PDF file from image files (mostly Tiff and Jpeg). I use the code from the Delphi Demo to insert images into a PDF (see below). For 112 pages that took for black/white Tiff images 6 seconds and for 112 pages Jpeg images 17 seconds. For our purpose this is to slow. We previously used a different tool for this and that did the creation of the PDF's (on the same PC in the same application at the same moment) in less than a second.

Is there a way to accomplish this much faster?

Code: Select all

  lResult := PXC_NewDocumentEx(@lDocument, sDDiPXC40Key, sDDiPXC40DevCode, 2);
  PXC_ErrorCheck(lResult);

  for idx := 0 to FileList.Count - 1 do begin

    lResult := PXC_AddImageW(lDocument, PChar(FileList[idx]), @p);
    PXC_ErrorCheck(lResult);

    lResult := PXC_GetImageDimension(lDocument, p, @iw, @ih);
    PXC_ErrorCheck(lResult);

    lResult := PXC_AddPage(lDocument, iw, ih, @page);
    PXC_ErrorCheck(lResult);

    lResult := PXC_PlaceImage(page, p, 0, ih, iw, ih);
    PXC_ErrorCheck(lResult);

    lResult := PXC_EndPage(page);
    PXC_ErrorCheck(lResult);
  end;

  lResult := PXC_WriteDocumentW(lDocument, FFileName);
  PXC_ErrorCheck(lResult);

  lResult := PXC_ReleaseDocument(lDocument);
  PXC_ErrorCheck(lResult);

Hello ddi development b.v.,

I've asked one of our Tools SDK experts, but he just told me that there is no faster way possible with our products.
