PdfOCRCreateFromMultipageTIFF hangs

[daninden]

I'm using the function PdfOCRCreateFromMultipageTIFF to create a searchable PDF/A from a MTIFF file.
With some documents this works as expected, other documents hang (take extremely long) on this function (and never return to perform the next line of code).

Code: Select all

                    oGdPictureImaging.OCRTesseractReinit();
                    oGdPictureImaging.OCRTesseractSetPassCount(1);
                    oGdPictureImaging.PdfOCRCreateFromMultipageTIFF(id, TesseractDictionary.TesseractDictionaryDutch, this.apppath + "\\OCR\\", "", path + "pdf", true, "", "Doclogic", "", "", "Doclogic Barcode Processor");
                    oGdPictureImaging.OCRTesseractClear();

maybe someone can help me with this problem.

I tried a different approach to see which page is creating the problem:

Code: Select all

                    int PdfID = oGdPictureImaging.PdfOCRStart(path + "pdf", true, "", "", "", "", "");
                    for (int x = 1; x <= oGdPictureImaging.TiffGetPageCount(id); x++ )
                    {
                        oGdPictureImaging.TiffSelectPage(id, x);
                        oGdPictureImaging.PdfAddGdPictureImageToPdfOCR(PdfID, id, TesseractDictionary.TesseractDictionaryDutch, this.apppath + "\\OCR\\", "");
                    }
                    oGdPictureImaging.PdfOCRStop(PdfID);

when debugging it seems all pages get added properly, but it hangs again on the PdfOCRStop function.

Nevermind,

it works now.
I changed the gd init functions to be set on the current thread, and removed the SetLicenseNumberOCRTesseract.
Either of those fixed the problem (i guess the latter).
