Even in my dotage, When I'm in a goodish mood, no grumps in sight, I like to have a fiddle with apps, just to see what's what. ;-) Thought I'd have fiddle with Sleuth3 just to see how much of a masochist I'd have to be to get a usable OCR out of it. I have an Epson scanner attached to my home LAN that outputs excellent images, unfortunately UniServer/Uniscan has never been able to do anything through it, just interminable clicking. I just rechecked... Click, click... :-( I have a small clean recent document printed on a HP Laserjet (Win side) to use in the scanner. In the Epson Scan app while scanning, I used a tiny bit of 'Contrast' increase to crisp up the images. Scan in 8bit Grayscale at 100, 150, 200, 300, 400 dpi. Take the images (Not Jpegs as I want to keep the images clean) to the RISC OS side. (BMP or PNG) Use DPlingScan to reduce to 4bpp then Save as a Spritefile. 100, 150, 200dpi completely useless. 300dpi OCR'd very well with just a few things out of place. 400dpi OCR'd completely okay. There yuh! go. Dave -- Dave Triffid
