[comp.text] Canon scanner - ReadRight format?

kbe@dde.uucp (Kjeld Borch Egevang) (05/02/89)

I have tried using a Canon scanner and some software called ReadRight.
I wasn't really impressed of it's capabilities, so I thougt of having a
look at the pixels myself. It's possible to get a dump from the system
containing the graphic image - but I can't figure out the format. I really
tried hard to decipher the bits and I've found out this much:

1) The first part of the file is garbage and is not used
2) Then comes the graphic, line after line (horisontally). The lines start
   with a pattern (can't remember it right now) and an offset to the next
   line.
3) I guess the lines tell how long the distance is to the next point where
   black goes to white or vice versa.
4) It's kind of bit-oriented because I found something like:
   1. line: ...00010101010100101000000101
   2. line: ...0001010101010010100000010010000000
   (seccond line takes another byte to get one more bit)

I used a 300 dpi resolution. I suspect that there might be some floating
point numbers or some correction-bits.

Is there anybody out there who can help me?
