Generating a PDF with Tesseract C++

[Saliaj Adrian]

Hello,

I am testing the Tesseract C++ API.

Here is my code :

#include <tesseract/baseapi.h>
#include <leptonica/allheaders.h>

int main()
{
    fprintf(stderr, "Heyhey !\n");
    char * outText;

    tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
   
    if (api->Init(NULL, "fra")) {
        fprintf(stderr, "Could not initialize tesseract.\n");
        exit(1);
    }
   
    Pix * image = pixRead("/path/test.tif");
    api->SetImage(image);
   
    outText = api->GetUTF8Text();
    printf("OCR output:\n%s", outText);

    api->End();
    delete [] outText;
    pixDestroy(&image);

    return 0;
}

It works and display the text output.

But how can I get a searchable PDF file output and save it on my computer ?

I mean, exactly like the command line : tesseract test.tif output pdf

Thanks a lot

Have a look at tesseractmain.cpp e.g.: https://github.com/tesseract-ocr/tesseract/blob/master/api/tesseractmain.cpp#L351

So I must set the variable "tessedit_create_pdf" at true, but how ? I do not find the setter.

Thanks

Really? Where did you look?

https://github.com/tesseract-ocr/tesseract/blob/master/api/baseapi.h#L165

BTW: It seems you did not not understand that example: setting variable will not help you.

Thank you but it still doesn't work...

Can someone just tell me what should be add to this code to generate a PDF output ?

#include <tesseract/baseapi.h>
#include <leptonica/allheaders.h>

int main()
{
    fprintf(stderr, "Heyhey !\n");
    char * outText;

    tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
   
    if (api->Init(NULL, "fra")) {
        fprintf(stderr, "Could not initialize tesseract.\n");
        exit(1);
    }
   
    Pix * image = pixRead("/path/test.tif");
    api->SetImage(image);
   
    outText = api->GetUTF8Text();
    printf("OCR output:\n%s", outText);

    api->End();
    delete [] outText;
    pixDestroy(&image);

    return 0;
}

Thanks a lot
