Scanning is the process of making an electronic copy of a print image, for
example a photograph. We have one PC set-up to scan using a program named
PhotoImpact. You scan images, saving them on your network drive in BMP
format. You can then edit your scanned images using PaintShop Pro on the
main Lab PCs. You may, for instance, want to use PaintShop Pro to save the
image in GIF or JPEG format.
The scanner is a delicate instrument. It's the only one we have. Please
be gentle with it and don't put books or other heavy objects on it. The
object glass needs to be kept very clean, so do your best not to touch it.
The scanner PC should be used only for scanning. Use the main PCs for
editing images and other work.
This is fine for getting started. If you're interested in learning more
about the technical details of scanning, see
- The scanner PC runs Windows 95, so logging on, etc. is a little
different from Windows NT. Log onto the computer (before doing so, make
sure you logged off all other computers) from the Enter Network
Password dialog box. Type your name, password, and domain. In case
you've forgotten, you domain is students .
- Turn on the scanner. The power switch is on the right rear of the
- Carefully place your image on the scanner bed. ``Ground zero'' is
the lower left-hand corner. The image should be placed face-down, as if
you were using a copier.
- Open PhotoImpact SE. You'll find a shortcut for it on the Windows
- From File menu, choose Acquire, then choose
Image. An Acquire Image dialog box should pop up. In this
dialog box, make sure that only New Image is checked --- everything
else should be un-checked. Press the Acquire button.
- A Preview window should now open. In this window, press the
Preview button and the scanner will take a preview scan.
- Press the Zoom button (leftmost button) and drag the zoom
frame around that part of the image that you're interested in. When you're
finished dragging, click inside the frame you just made and a zoomed
preview scan will be done.
- Press the Frame button (next to the Zoom button). Drag this
frame around that part of the image you wish to acquire. This allows you
to crop your image.
- You will notice there are three buttons in the upper-right hand
corner of the Preview window. The top-most of these opens and closes the
Settings Window. Open the Settings Window. Make sure that type is
set to Millions of Colors and that the resolution is set to
300 dpi. Make sure that the check boxes for Auto Contrast and Color
Correction are checked. You can use Scaling to change the size of
the scanned image. You would use this, for instance, to create thumbnail
images. When you are finished with these adjustments, close the Settings
- Press the Scan button. The framed part of the image will be
acquired and transferred to PhotoImpact. After the image is acquired, you
can close the Preview window.
- Back in PhotoImpact, save your image. Make sure you save your image
into your appropriate network folder!!! You should save the image as type
BMP --- the Windows Bitmap format.
- If you have another image to scan, return to step 2.
- When you're finished scanning images, close PhotoImpact.
- Make sure you take all your images with you!!!
- Logout: press the Start button and choose Shutdown.
From the Shutdown dialog box, choose Close all programs and... .
- Turn off the scanner.
- Make sure you close the door as you leave.
, especially the links ``Scanning 201'' and ``Video Resolution --- How Much
to Scan?'' For instance, for video applications DPI adjustment should
really be used to adjust image size, not scaling.
This is just a brief introduction to PaintShop Pro --- just enough to show
you how to save a Bitmap file as a GIF or JPEG file.
Once you've saved a Bitmap image as either a JPEG or GIF image, delete the
Bitmap file so that your homepage directory doesn't become too cluttered.
- After logging onto one of the Windows NT PCs, press the Start
button, choose Programs, find and goto the PaintShop Pro
entry and open PaintShop Pro 4.
- Open your Bitmap image.
- From the File menu, choose Save as.
- If you want to save your image in GIF format, set the type to GIF and
the sub-type to Version 89A, either interleaved or non-interleaved. Press
the Options button and make sure that the image will be saved with
no transparency information.
- If you want to save your image in JPEG format, set the type to JPG.
- Press Save to save the file.
- Repeat for any other images you want to convert.
