Leaving them
as a scanned image is the easy way out, but isn't always
practical. Some pages I have have very small print, and the resolution
of the image required to make this text readable makes for huge files.
For pages that consist solely of text and line art, scan them as 300 DPI
TIFF Class F Group 4. That takes only 40-120K per page. I put the
resulting images into a PDF file, since most people don't have any other
G4-capable reader, and G4 is supported as a native PDF image format.
This is what I have been doing.... I gave up on JPG and GIF even though
they are directly supported by the major browsers because the image
quality wasn't there and file sizes were getting out of hand when attempts
were made to preserve image quality.
TIFF on the other hand, works well, and is quite compressable. Pretty
much consigns you to putting them in a PDF though, which isn't all that
evil I suppose.
The one attractive thing we loose by creating 60meg PDF files is the
ability to browse pages without downloading the entire thing....
Or am I missing something in Acrobat that will pull pages on demand
from a table of contents?
Some people always flame me about disliking PDF because
they can't run
Acrobat Reader on their Commdore 64, but realisticly I've found that more
people have access to Acrobat Reader than any other viewer. My attitude
is that if I spend the time to scan the docs and make them available
free on my web site, people that don't like it can take a hike.
I have no real problem with PDF. I am just trying to reduce my labor
investment, and produce quality end results.
I've written a program using PDFlib to automate
creating the PDF from a
directory full of G4 files.
This sounds rather useful... :-)
For greyscale and color images, I'm working on a
process to separate out
the images, use G4 coding on the monochrome portion of the page, and
overlay the images in JPEG format. This will also work nicely with
Acrobat reader, since it can support overlaid images, whereas most other
viewer software can't.
This will help a lot too....
Some results of my scanning can be seen at
www.36bit.org. Note that
most of those scans were done *before* I got a sheet feeder. In my
experience, although there is some skew with the feeder, there is less
skew than when I do the pages manually, and the skew is more consistent
from page to page. If I get really motivated I'll write some deskewing
software.
What scanner are you using? Your scans look pretty good. Did you do
that 500+ page manual by hand or with the sheet feeder? :-)
Right now I have a stock HP Scanjet 4C, but am considering investing
in a ledger-size scanner with a decent sheet feeder so I can archive
not only my manuals, but my printsets as well.
