Support reading from screen grabs
Screen grabs have too low a resolution for VelOCRaptor to work well. Rescale them before reading so that they work.

It would be really helpful if I could OCR from a screen capture. Thanks.
I need screenshots to be able to be read
I wanted to get some text out of a book at Google Books. The first screen shot produced a poor result in VelOCRaptor, but after I enlarged the print several steps (which also required enlarging the Safari window), it worked well enough. I also tried saving the screen shot as a TIFF, but it didn't seem to work any better than the PNG I normally use.
Offhand I can't think of another situation where I'd need to use a screen shot to get text, except Web pages like Google Books where the text can't be copied; but sure, I expect that as OCRopus gets smarter, VelOCRaptor should be able to work with more marginal input.
are you using 10.6? if so, create a service(dienste) for ocr'ing screengrabs.
i choose a shellscript for my solution, with 'sips' scaling the screenshots,
to temporary 300dpi, reading once a pdf then reading a txt.
the txt gives very varying results.
some are excellent,

Screen grabs sooooo useful (Sure, only at times, but there is nothing out there that can, yet. (SelectAll_Copy a Finder window gives you a text file of the file *names, but there are time where the dates are important, and I can see this cute raptor doing the job, one day.
