Q: How do I determine if I am scanning horizontally or vertically?

If you are scanning from the left side of a document to the right side of a document, then you are scanning horizontally. Under Stitching Tools in the top left of the Stitching interface, select Scanned Horizontally.

If you are scanning from the top of a document to the bottom of a document, then you are scanning vertically. Under Stitching Tools in the top left of the Stitching interface, select Scanned Vertically.

Q: How do I adjust the Settings in the Stitching interface?

Navigate to the Settings in the Stitching interface. Under Stitch Settings, you can adjust the stitch quality by increasing the edge blend and sensitivity. Make sure to test the default settings first. You can reset to the default settings by hitting the Defaults button to the right of the settings bars.

The Increase Edge Blend setting refers to the Gaussian smoothing algorithm that is applied to the stitch. It is most useful when scanning highly detailed images. Make small adjustments (10% or less) by moving the slider on the settings bar from the default setting towards right. Continue testing small adjustments until you have found the optimal setting.

The Increase Edge Sensitivity setting refers to the Harris Corner Detection algorithm that is applied to the stitch. It is most useful when scanning images that include a lot of lines or text. Make small adjustments (10% or less) by moving the slider on the settings bar from the default setting towards right. Continue testing small adjustments until you have found the optimal setting.

Q: My stitched image is slightly rotated. How do I fix this?

Q: The darker sections of my stitched image are being cut out. How do I fix this?

Q: Why is the stitching timing out/crashing?
