Scan Area & Cropping
For those instances not requiring the full scan area of the camera, fully variable
image cropping is provided. Both proportional cropping (using the Scan Area up/
down buttons) and manual cropping (using the crop tool or the Size panel) can be
used to select any desired rectangular area within the full scan area. In addition to
reducing the size of a scanned image file by eliminating unwanted data, cropping
can decrease overall scan times by reducing the number of lines to be scanned.
To use proportional cropping , click the Scan Area Increase or Decrease buttons; click and
hold either button to advance rapidly through the selections. Each click causes the cropping rectangle
to grow or shrink proportionally, until an image boundary is reached.
Hold down the Option key and click on the Scan Area Increase button to move immediately
to the largest scan area (100%) or the Scan Area Decrease button to move to the smallest
scan area (1%).
To use manual cropping , select the Crop Tool from the tools located above the preview
window. The crop rectangle will appear in the preview window with a handle in the center of each
edge and a handle in each corner. When the mouse cursor is moved over one of the handles the cursor
will change to a , or to indicate the direction the edge or corner can be moved. Click and drag
one of the handles to resize the crop rectangle. The crop rectangle will change as long as the mouse
button is held down. When the rectangle edge or
corner is at the desired location, release the mouse
button. When the cursor is within the crop rectangle
the cursor will change to a to indicate that the
crop rectangle may be repositioned by clicking and
dragging the cursor to move the crop rectangle to
the desired location. Changes to the crop rectangle
will affect the Scan Area, Scan Time, Image Size
and histogram displays and these will update in real
time as the crop rectangle is adjusted.
