Does the 300 dpi bitonal rule apply for OCRing all text found in all books? What's the smallest point size text which 300 dpi bitonal will still allow reasonably accurate OCR (at least sufficient for the DP process)?
No, but it's a good rule of thumb. Indeed, the resolution may even be smaller, as some of the content providers (wrongly, in my opinion) resize the images before uploading to reduce the image size so that the images load at an acceptable speed for dialup users. Those of you wanting to use DP's page images as the basis of an image archive must realise that DP's primary use for the images is as an aid for proofing... it would actually make life worse, not better, for the majority of DP's users and content providers if we started using higher resolution, grayscale images. -- Jon __________________________________________________ Do You Yahoo!?
