18.3.3 Scanning an Image
Instead of opening an existing image or creating a new one, you can scan one. To scan
directly from The GIMP, make sure that the package xsane is installed. To open the
scanning dialog, select File > Acquire > XSane: Device dialog.
Create a preview when the object to scan is smaller than the total scanning area. Press
Acquire preview in the Preview dialog to create a preview. If you want to scan only
part of the area, select the desired rectangular part with the mouse.
In the xsane dialog, select whether to scan a binary (black and white without shades of
gray), grayscale, or color image and the required scan resolution. The higher the reso-
lution, the better the quality of the scanned image is. However, this also results in a
correspondingly larger file and the scanning process can take a very long time at higher
resolutions. The size of the final image (both in pixels and bytes) is shown in the lower
part of the dialog.
In the xsane dialog, use the sliders to set desired gamma, brightness, and contrast values.
These sliders are not available in binary mode. Changes are visible in the preview im-
mediately. Once all settings have been made, click Scan to scan the image.
18.3.4 The Image Window
The new, opened, or scanned image appears in its own window. The menu bar in the
top of the window provides access to all image functions. Alternatively, access the
menu by right-clicking the image or clicking the small arrow button in the left corner
of the rulers.
File offers the standard file options, such as Save and Print. Close closes the current
image. Quit closes the entire application.
With the items in the View menu, control the display of the image and the image window.
New View opens a second display window of the current image. Changes made in one
view are reflected in all other views of that image. Alternate views are useful for mag-
nifying a part of an image for manipulation while seeing the complete image in another
view. Adjust the magnification level of the current window with Zoom. When Shrink
Wrap is selected, the image window is resized to fit the current image display exactly.
