I have been using the free version for reading the text from pdf files. It worked OK with a few pdf files except a particular one (please see attachment).
The Code I used:
- Code: Select all
var sb = new StringBuilder();
var doc = new PdfDocument();
doc.LoadFromFile(filePath);
foreach (PdfPageBase page in doc.Pages)
{
sb.Append(page.ExtractText()); //it throws exception here
}
doc.Close();
The exception I got:
- Code: Select all
System.ArgumentException
HResult=0x80070057
Message=Parameter is not valid.
Source=System.Drawing
