tesseract-ocrHow do I use the Tesseract OCR documentation?


The Tesseract OCR documentation provides detailed information on how to use and integrate the Tesseract OCR library into applications. To use the Tesseract OCR documentation, you will need to install the Tesseract OCR library first.

To install the Tesseract OCR library, you can refer to the official installation guide here.

Once the Tesseract OCR library is installed, you can then refer to the Tesseract OCR documentation to integrate the library into your application. For example, a basic example of using the Tesseract OCR library to recognize text from an image would be as follows:

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

int main()
{
    // Initialize tesseract-ocr with English, without specifying tessdata path
    tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
    api->Init(NULL, "eng");

    // Open input image with leptonica library
    Pix *image = pixRead("test.png");
    api->SetImage(image);

    // Get OCR result
    outText = api->GetUTF8Text();
    printf("OCR output:\n%s", outText);

    // Destroy used object and release memory
    api->End();
    delete [] outText;
    pixDestroy(&image);

    return 0;
}

This example code will output the recognized text from the image test.png:

OCR output:
This is a test image.
