Image Format

[Tom Droege <tdroege@veriomail.com>]

Arne has asked me to work on the PROMS to write a better format for the 
dark pixels.  This has required me to look again at what I think I am 
writing.  Per a bunch of old messages, what I think I am writing is not 
what I am writing.  Eventually I fussed with the read program until the 
picture came out looking like a picture.  If the number of pixels in a line 
is set wrong, then the image comes out with each line offset from the 
last.  I think I am writing 2040 pixels per line.  One has to read with 
2043 pixels in the line.  I keep looking at the code and cannot figure out 
what is wrong.  I guess everyone will want to know.   Here is my plan:

Write up a note about how the scanner works.

Add more comments to the programs that writes the prom code.

Add comments to the programs that read the data out of the memory.

Write up a note about the software that takes an image.

When I am done with the above, I may see the error(s).

In any case, I will "publish" everything above.  Possibly some of you can 
then step in and make sense of what I have been doing.

As a first step, I will write up a message that outlines what I think I am 
writing.  I should get this done tomorrow so Rob can make better sense of 
the pixels he is looking at.  But I warn you all that whatever I put up is 
surely wrong.
