Scanning
[ Update coming soon!]
There are two software packages installed on Linden which allow the
user to scan images into the computer using the Mustek A3SP SCSI scanner.
Photoshop and Gimp both have similar methods, but look and function
slightly differently. Use which ever program you are used to or more
familiar with.
- Put the document on the flatbed scanner
- Align it on an edge, if possible. This ensures that the picture will
scan in more level.
- Load the software of your choice. I'll walk through Gimp here, since
it is faster.
- Go to ``file'', select ``acquire'' than ``twain32''. Select
Mustek A3SP from the window.
- You can also take screen shots with this.
- This will open up the dialogue window from the software which drives
the scanner. This dialogue window is the same whether you are using
the Gimp or Photoshop.
- Double check the settings for the type of picture you want to scan
in.
- If it is a text document, make sure you either select ``gray-scale''
(if there are pictures in it) or black and white. If it is a color
picture, select color.
- There is no need to go above 24 bit.
- Select the resolution you desire.
- If it's a gray-scale picture and you want to print it to the HP Laser
jets, scan it in at 1200 DPI.
- If the image is to be sent across the web, 300 DPI should be sufficient.
- If the item is very large, and text, consider 75 or 150 DPI.
- 1200 DPI is the maximum that I'd recommend. There's not much need
to go larger, unless you really need it.
- Select the Field you wish to scan by moving the select box around
on the preview on the right side of the dialogue box.
- Click ``scan'' when ready.
- This will open up (after several seconds to a few minutes) a window
with in Gimp (or Photoshop) with your scanned picture in it.
- After examining it, and making any modifications that you wish, save
the picture.
- I recommend saving to either JPG or Tiff. PNG is also descent.
- Jpeg (*.jpg). General use for pictures and web pages.
- There is usually a compression setting (image quality) you are prompted
for when saving to this format. Generally, the default setting is
good. If you want to put the image on a web page, shrink it down by
reducing the quality, which increases the compression.
- PNG is portable and good quality, but not very versatile.
- If the item is very large, and text, consider 75 or 150 DPI.

- Gif is good, if you can use it.
- Tiff is raw and uncompressed. Use only when you know you need it.
