Google Chrome's PDF viewer is gaining the ability to convert images to text
PDFs are astonishingly useful documents, but some are lazily created. You've almost certainly encountered a PDF file that comprises images of text rather than selected text. This is a serious annoyance if you were hoping to copy text into another document, but it's also a major problem for anyone who is reliant on text-to-speech tools to have document read aloud to them.
Google has some good news for users of Chrome; the browser is gaining the ability to convert images to text in PDFs, OCR-style. There is some bad news, however. This incredibly useful feature is -- at least initially -- not going to be made available to everyone.
