Crop tab

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

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

Auto crop

This option controls whether VueScan automatically computes the X/Y offset (mm) option, or whether it is entered manually.

If you turn off the "Crop|Auto crop" and "Options|Auto exposure" options, then the "Scan|Device" command won't first do a preview scan. This can save time when batch scanning.

X/Y offset (mm)

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 in the Device tab, and other values let you specify some standard crop sizes.

X/Y size (mm)

This is the size in millimeters 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.

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 in millimeters 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.

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).

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.

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.
