You can also select a specific scan resolution from the list.
Basic Option: This option is always displayed.
Input | Scan dpi
If Input | Scan resolution (p. 55) is set to "Custom", the scanner will use a
hardware-supported resolution that is greater than or equal to this value. VueScan will
rescale the image to the requested resolution.
Note that this uses simple rescaling, so if quality is an issue, you should use an external
image editor to rescale the image.
Basic Option: This option is displayed whenInput | Scan resolution (p. 55) is set to
"Custom".
Input | Auto rotate
VueScan will detect the orientation of text images when the media type is set to Text,
Line art or Microfilm. When the image is scanned, this option causes the image to be
analyzed and the page is rotated to be upright.
Advanced Option: This option is displayed when scanning Text, Line art or Microfilm.
Input | Auto flip
If this option is set, the page orientation is flipped every time an image is saved. This is
to allow easier scanning of books and magazines.
Advanced Option: This option is always displayed.
Input | Rotation
This option describes the orientation of the images in the Preview and Scan tabs and in
TIFF, JPEG, PDF, Index and Raw files. This is relative to the unrotated image that
comes from the scanner.
Don't have much memory on your system? Set this option to "None" and rotate the
image later with an image viewer - this will make the cropping faster. Using "Right"
rotates 90 degrees clockwise, using "Flip" rotates 180 degrees, and using "Left" rotates
90 degrees counterclockwise.
Note that rotation happens after mirroring.
Basic Option: This option is always displayed.
Input | Auto skew
Use this option to automatically compute the skew angle for images that aren't quite
straight.
