Crop tab

The crop tab lets you specify full automatic cropping, full manual cropping and a range of options between.

Note that a VueScan also lets you change these values by using the mouse in the preview image.

Crop units

Use this option to choose the units to use when display measurements in the Crop tab. You can choose pixel, mm, cm or inch units.

Crop auto position

If this option is set, the crop box is positioned automatically, finding the best placement of this box to capture as much of the image as possible.

If you clear this option and set the "Device|Lock exposure" option, then pressing the "Scan" button won't first do a preview scan. This can save time when batch scanning.

X/Y offset

This is the offset in the scan region of the start of the image data.

Crop size

This option lets you choose how the size of the cropped area is chosen. "Manual" lets you enter all the crop size options manually, "Auto" computes all the values using heuristics, "Maximum" crops the entire area specified the "Crop|Region", and other values let you specify some standard crop sizes.

Landscape

If set, the size specified in the "Crop size" option is oriented in the landscape direction (i.e. it's wider than it is tall).

X/Y size

This is the size in of the image area that you are cropping. If set to zero, the entire scanned area will be used.

X/Y images

Set these options to the maximum number of images to look for in the horizontal/vertical direction. It should normally be 1 except when scanning film strips on the PhotoSmart. in which case it should be a number greater than or equal to the number of images on the film strip being scanned. You can also use these options to scan an array of images on a flatbed scanner.

If a film strip doesn't crop correctly, try reducing this value to the exact number of images on the film strip. This may be necessary if you have tape on part of the negative strip.

X/Y spacing

This is the approximate size of the spacing between the start of images in the horizontal/vertical direction.

This value is only used if the number of images in the horizontal/vertical direction is greater than 1.

Border (%)

This is the amount to increase the cropped size of an image. This increased border area isn't used for computing the color correction of an image. Use this value to add white (or black) space around an image if you want to later crop the images by hand, or if you want to capture the complete area around an image.

Buffer (%)

This is the size of the buffer area inside the cropped area to ignore when computing the color balance of the image. It is used to reduce the effect of a small amount of black or white border on the overall image color balance. Note that this should always be a few percent larger than "Crop|Border (

Region

The scan region is the subset of the total scan area that gets scanned to produce a preview. This option can be set up so the region can be specified manually, so it can be the maximum possible size or so it can be the default region size for the device.

Region X/Y offset/size

These options describe the size of the scan region. They are relative to the upper left-hand corner of the image, negative, or slide.

Note that you should be careful to not set the Scan y size to a value larger than 190.5 mm on the PhotoSmart scanners, since there have been reports of scratched film when scanning longer lengths than this.

Focus X/Y offset

This option determines where the auto focus is centered. This position is displayed on the preview as a small animated box.
