[Coco] OT: scanners

[Kevin Diggs]

Hi,


	This is off topic but kinda inspired by the Rainbow archive project. I 
recently picked up a Lacie Silverscanner II off eBay. This thing has 
separate red, green, and blue lamps. Is this common?

	I've been playing with scanning the June 91 issue. Scans at 100 dpi (or 
ppi or lpi ... I don'k know) and line art mode (monochrome?) are 
readable. OCR would require some REALLY good software. PNG files of 
these black and white text pages are about 55k. For some of the pages 
that are not black and white I've tried 8-bit color and 8 and 4 bit 
grayscale. The 8-bit grayscale mode, in particular, seems to encourage 
the scanner to magnify imperfections on the pages. This produces rather 
large files. Some with PNGs approaching 1M.
