which format is best for screen capture in prep for OCR?
When taking a screen capture in preparation for OCR, should one take the screen capture in PDF or is there an advantage in terms of OCR accuracy in taking the screen capture in another format, e.g., png or tiff, and then letting the OCR software or some other software do the conversion to PDF?
In my tests, I'm seeing some minor differences in image and OCR quality, and some more significant differences in file size, depending on which software, graphic format, and settings I'm using and was wondering if there was some general guidance regarding format for taking screenshots for OCR'ing.
Thoughts?
