His, thanks for your message, I really should have scrutinized the documentation first. I tried scaling the image to 1779x100px and set resolution to 92dpi (all in gimp)
Tesseract produces then: HHhhhhhhhhhhhhVhVhVhVhVhVHHHHHHhhhhhhhhhhhhVhVhVhVhVhVHHHHHHhhhhhhhhhhhhVhVhVhVhVhVHHHHHHhhhhhhhhhhhhVhVhVhVhVhVHHHHHHhhhhhhhhhhhhVhVhVhVhVhVHHHHHHhhhhhhhhhhhhVhVhVhVhVhVHHHHHHhhhhhhhhhhhhVhVhVhVhVhVHHHHHHhhhhhhhhhhhhVhVhVhVhVhVHHHHHHhhhhhhhhhhhhVhVhVhVhVhVhVHHHHHHhhhhhhhhhhhhVhVhVhVhVhVHHHHHHhhhhhhhhhhhhVhVhVhVhVhVHHHHHHhhhhhhhhhhhhVhVhVhVhVhVHHHHHH$lll 444l<W<<il4 IUJWWIIIIIIIIWNUWWWlUJ <|1U Could you please advise if I am heading in the right direction by trying to scale image to get a meaningful text out even though the original is ocr averse? thanks On Fri, May 29, 2009 at 7:06 PM, Ray Smith <[email protected]> wrote: > RTFM.
