Scanning Your Image

As mentioned earlier, a separate program (usually the scan program that came with your scanner) actually processes a scan, even though you're capturing the image within the image editing program. Because scan programs vary according to the make and model of the scanner, the example dialogs may be slightly different than what you will actually see on your computer screen. To scan an image from within GIMP, select File > Create in the Toolbox.

You now have the following choices:

• You can choose Create > From clipboard to load an image that you previously copied to the clipboard (using the Copy menu item) as a new image in GIMP. You can also do this with screen shots (i.e., a copy of what is currently displayed on your computer screen). Under Windows, simply press Ctrl+Print Screen.

• You can choose Scanner/Camera if you want to scan an image or download an image from your camera.

• You can choose Screen Shot to make a copy of what is on the screen at the moment. This is added as a new image.

For this exercise, choose Scanner/Camera. This opens the Select Source window, where you can select your scanner (or any other device that is attached to your computer as a TWAIN source, such as your camera). In the Select Source window, select your scanner and click the Select button to accept your choice (Figure 2.38).

If both your scanner and your scanner's software were properly installed, a dialog box specific to your scanner will appear. Because this dialog comes directly from your scanner's software rather than GIMP, it might look and work a little differently than in the example. If you are a Linux user, you will be using the XSane program instead.

With the material or image you want to capture placed face down on the scanner, you can use the scanner's dialog to determine how it will be scanned.

TWAIN is an acronym for Technology Without An Interesting Name; it's also the standard "name" used when referring to image capturing devices for the Windows platform.



Most scan programs provide the following options:

Number of colors to be scanned, i.e., color depth (black and white, grayscale, color).

Original document type, such as text, image, or film. Some scanners come with an add-on device that allows scanning of photo negatives and slides.

Scanning resolution (usually selectable in predefined values, given in dpi). Furthermore, you normally find two buttons: A Preview button that activates a low-resolution preview scan A Scan button that starts the scanning process

Insert your original document in the scanner. If you click the Preview button, the image will be quickly scanned and displayed in the preview window. The scan software will automatically identify the image margins and mark them with a dashed line that is sometimes referred to as the selection frame or marquee. You can resize the selection frame by hovering the mouse above it and then clicking and dragging the dotted line until you've selected the area of the image you want to scan.

Click the Scan button to activate the actual scan process. Once the image is read, GIMP will open a new document for the scanned image. Close the scan program, and don't forget to save the new image.

Exercise: Try to scan an image from within GIMP, following the given procedures.
