Fetch Text From Image In Selenium

To get a text from the Image in selenium, we use Optical Character Recognition (OCR) with Tesseract (tess4j). Tesseract Supports UTF-8 Unicode.

• First, we need to create a folder with the name “tesseract” in our project and put trained data in that folder. You can find trained data for any language from the below URL:

https://github.com/tesseract-ocr/tessdata

Just Download eng. trained data for English Language and put it into Tesseract Folder for your project.

• Add below is maven dependency for tesseract (tess4j):

<dependency>

<groupId>net.sourceforge.tess4j</groupId>

<artifactId>tess4j</artifactId>

<version>4.5.4</version>

</dependency>

• Below is the Java code to fetch text from the image:

ITesseract image = new Tesseract();

image.setDatapath(“Location for TessData Folder”);

image.setLanguage(“eng”);

String str1 = image.doOCR(new File(“Location Of Image”));

String folderLocation = “Location Where we need to save Image”;

String pdfLocation = “Location where we have PDF File”;

PDFUtil pdfUtil = new PDFUtil();

pdfUtil.setImageDestinationPath(folderLocation);

pdfUtil.savePdfAsImage(pdfLocation);

• Below Java Code is used to Fetch Image From PDF

String folderLocation = “Location Where we need to save Image”;

String pdfLocation = “ Location where we have PDF File”;
