Converting PDF Images Into Text
To get from a scanned PDF image file to a searchable text file, there is a special type of software that you can use. OCR software can convert PDF images to text by recognizing the text characters using their optical features. OCR software has been used to scan virtually every kind of document and convert it into text. From invoices to entire books, all documents become more easily accessible with the use of OCR.
OCR relies fully on the optical properties of text characters to make documents text-searchable. Thus, it is important to understand that the quality of the scanned image, and the image processing capabilities of the OCR software, determine the quality of the results. Some images need to be de-skewed in order for the text to become readable; otherwise the characters in the document might not match up to the characters in the software memory.
