Apsose pdf introduces space when the pdf document has chinese characters

Aspose.PDF Product Family

Hi,


I am trying to extract text from a pdf document. The pdf document has some chinese characters. So when I use the text absorber, I am seeing that it introduces unnecessary spaces between the characters.

private String extractText(byte[] inputContent) throws IOException{

ByteArrayInputStream stream = new ByteArrayInputStream(inputContent);

Document pdfDocument = new Document(stream);

// Create TextAbsorber object to extract text

TextAbsorber textAbsorber = new TextAbsorber();

// Accept the absorber for all the pages

pdfDocument.getPages().accept(textAbsorber);

// Get the extracted text

String extractedText = textAbsorber.getText();

return extractedText;

}


I am also attaching the java code and the pdf file.

The full java code is below:


import java.io.IOException;


import com.aspose.pdf.Document;

import com.aspose.pdf.TextAbsorber;



public class PDFTester {

private static final String pdf_license = "Aspose.Pdf.lic";

static {

//Initialize aspose PDF license

try {

com.aspose.pdf.License pdfLic = new com.aspose.pdf.License();

pdfLic.setLicense(pdf_license);

} catch (Exception e) {

}

}

public static void main(String[] args) throws IOException {

String extractedText = extractText("aspose_issue.pdf");

System.out.println(extractedText);

}

private static String extractText(String file) throws IOException{

Document pdfDocument = new Document(file);


// Create TextAbsorber object to extract text

TextAbsorber textAbsorber = new TextAbsorber();


// Accept the absorber for all the pages

pdfDocument.getPages().accept(textAbsorber);


// Get the extracted text

String extractedText = textAbsorber.getText();


return extractedText;

}

}






The console output of this is:

Hi Muthu,


Thanks for your patience. We have investigated about logged issue and would like to suggest you to use TextFormattingMode.Raw to prevent extra spaces

textAbsorber.getExtractionOptions().setFormattingMode(TextExtractionOptions.TextFormattingMode.Raw);


Furthermore, In TextFormattingMode.Pure mode setScaleFactor(…) method can also be used to control the amount of spaces between words.

Please feel free to contact us for any further assistance.

Best Regards,
