Prefs | Anti alias text

Controls whether 1-bit images (i.e. text and line art) are displayed with anti-aliasing.

This results in smoother looking displays but also takes a bit more computing power.

Advanced Option: This option is always displayed.

Prefs | Anti alias image

Controls whether gray-scale and color images are displayed with anti-aliasing. This

results in smoother looking displays but also takes a bit more computing power.

Advanced Option: This option is always displayed.

Prefs | Enable density display

Enables displaying the image density when the cursor is moved over the image with the

control key held down.

Advanced Option: This option is always displayed.

Prefs | Enable raw from disk

Enables the Output | Raw file (p. 88) option when scanning from disk. This is useful if

you want to re-scan raw scan files at a lower resolution or bits per pixel and save a raw

scan file with these changes.

Advanced Option: This option is always displayed.

Prefs | Enable TIFF thumbnails

When this option is enabled, TIFF files have a small preview embedded in them. This

makes displaying thumbnails of these files much faster, since only the small thumbnail

needs to be read, not the whole image. When the image is larger than 10 MBytes, this

is significantly faster.

These thumbnails are only embedded when the image is wider or taller than 2048

pixels and when the image has 8 or more bits per pixel.

Advanced Option: This option is always displayed.

Prefs | Disable scanners

Use this option to disable some kinds of (or all) scanners. This option isn't used by

default.

This is useful if you want to run multiple copies of VueScan at the same time, scanning

with one copy and processing raw disk files with another. To use this option, put

copies of VueScan in different directories, run VueScan, set this checkbox, then exit

and restart VueScan.
