Miss word after extract text from pdf

hi,

I want to extract text from pdf, but some words are missing. I’m using Aspose.PDF 21.7
here is my code:

Document document = new Document("C:\\Users\\xxx\\Desktop\\123 (3).pdf");
// Open document
String txtFileName = "C:\\Users\\xxx\\Desktop\\test-1.txt";

// Load PDF document
TextAbsorber ta = new TextAbsorber();
ta.visit(document);
// Save the extracted text in text file
BufferedWriter writer = new BufferedWriter(new FileWriter(txtFileName));
writer.write(ta.getText());
writer.close();

this is my pdf:
123 (3).pdf (38.2 KB)

Is it because we don’t have a license?

By the way, we are testing whether aspose meets our needs before purchasing the license. We have some questions and hope to be answered as soon as possible. Can aspose provide some channels for us to get a more efficient and timely response?
