Hello Dan,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
You can try using the following code snippet to check if the Pdf file contains text of is an Image pdf.
// Instantiate a memoryStream object to hold the extracted text from Document
MemoryStream ms = new MemoryStream();
//Instantiate PdfExtractor object
PdfExtractor extractor = new PdfExtractor();
//Bind the input PDF document to extractor
// Specify the Start page of the Pdf document
extractor.StartPage = 1;
// Specify the end page of the Pdf document. Limit the extraction to single page, rather than searching whole document
//Extract text from the input PDF document
//Save the extracted text to a text file
// Check if the MemoryStream length is greater than or equal to 1
if (ms.Length <= 1)
MessageBox.Show("Pdf is an Image Pdf");
MessageBox.Show("Pdf contains text");
