Software Used in Making Scanned PDF Accessible
Scanned PDF files are often compared to photographs as they have the same properties and that is why making scanned PDF accessible and recognizable by software is very important. When stating that scanned PDF files are like photographs it literally means that such files have all the problems that photographs have. Namely these files cannot be searched through with a text string and text cannot be captured from them using the copy/paste function which can be used easily with other electronic files. These problems arise because software that manage databases or even smaller software packages such as MS Word do not have the necessary features to capture text present on scanned files. So even though scanned PDF files are electronic versions of paper documents, OCR software needs to be used when making scanned PDF accessible to users and other software packages. As part of making scanned PDF accessible OCR software captures the text from such files and outputs it in the form of text searchable files such as MS Word or PDF.
