VB Forum / General 2 / March 2007Converting a PDF document image to text
I prgramatically save a PDF document as text using automation. I then process the document in VB. However, my client now has one of his clients sending an image of a document in a PDF file. What is the best way to convert the PDF image file to text using VB? Thanks. Greg > I prgramatically save a PDF document as text using automation. I then > process the document in VB.

SignatureRemove the ns_ from if replying by e-mail (but keep posts in the newsgroups if possible). If a PDF file is in ASCII format (As opposed to Binary) it should be possible to extract the text. Postscript is a well defined language and parsing the page is a possibility. I don't think the task is simple but it should be possible.

Rick Rick If the text is in the form of an image then "OCR" might be considered although I have never looked at using that technology in VB it is nowadays considered to be well established and widely used.
