Good OCR is about 98% accurate - that is two characters wrong in 100, or two spelling mistakes in about 15 words. After OCRing it is essential to proofread the resulting text before reprinting from it. Even worse are carbon copies on flimsy from the foregoing. Uneven old typewriting from fabric ribbon days on flimsy paper, which may be crumpled and discoloured, is not good. Good quality print on clean paper works best. The better the original from which you are working, the better the accuracy. OCR (in general) reads only type (not handwriting, whether joined up or block letters). OCR accuracy depends very much on the quality of the original. If one wishes to alter the text on the photograph pf a page of text (the scan), perhaps to lay it out in a different fashion, one must pass it through an OCR program, which "reads" the text and puts it into a file as if it had been typed in this file can then be passed to the text editor - in this case, Writer - as if it was input from the keyboard. When you have a photograph any text that is on it cannot easily be changed (one has to use special editors such as Photoshop). The computer can only handle this as a photograph, so if you put it into a text editor, it is put in as a photograph. Whether what is on the glass is a picture or a page of text, the output is still a photograph. A scanner is effectively a special type of camera it takes a photograph of what is on its glass. OCR stands for Optical Character Recognition. If you already know what OCR is, read no further. It came to me that the OP may be misunderstanding OCR. AFAIK the single step solution is not available with the apps in question here. Proofreading is required for most OCR situations, so even if it were available, I wouldn't recommend using automated scan-OCR-PDF. The "nitty gritty" procedure is to scan to image, then OCR from image to text, then import the text into your wordprocessor. Simply upload your file and our server side program will process your file for any editable text and will send the results back to you, you can then download the processed text.
#Pdf ocr scanner pdf
Almost as elegant and efficient as a plugin, and probably easier to implement. is a free online OCR service that allows you to convert PDF to Text, JPEG to Text and scanned images into editable text documents.
#Pdf ocr scanner software
Other scanners come with scanning software which can be set to "push" OCR output to applications such as Writer.
If they made such a plugin for OpenOffice, it may be possible to seamlessly import text from scanned image in Writer, IOW the plugin would provide OCR capability to OpenOffice.
#Pdf ocr scanner drivers
Scanner drivers or OCR software may come with an OCR plugin for various software. Alas, OpenOffice applications do not do OCR out of the box. There are several advantages to have the picture content converted to text. Menu sequence in Writer: Insert - Picture - Scan. When you have TWAIN compatibility (which you have with most scanners), you can scan from OpenOffice/LibreOffice. I'll try to rephrase what has already been stated, and fill in a few blanks. Mostly your questions have been answered, but perhaps in a roundabout manner.
