Chapter 9 Practical Examples

Scanned images are rotated as follows according to the orientation of loaded documents and the selected angle.

Feeder documents: face up

Image rotation (clockwise)

0°

90°

180°

270°

Flatbed documents: face down

• To rotate images to match document text

Select [Text Orientation Recognition] on the [Image processing] tab sheet. The text orientation on each page is detected, and the scanned image is rotated in 90-degree increments as needed for normalization.

When [Text Orientation Recognition] is selected, image rotation is disabled.

• To reverse black and white in scanned images (TWAIN driver only)

Select [Reverse Image] on the [Image processing] tab sheet. Black and white are reversed in scanned images. (See “[Reverse Image] Check Box (TWAIN driver only),” on p. 7-18.)

• To ignore a particular color when scanning

Select a color to be ignored (dropped out) in [Color drop-out] on the [Image processing] tab sheet, and that color will be eliminated from scanned images. (See “Color Drop-Out,” on p. 7-18.)

• To enhance a particular color when scanning

Select the color to be enhanced in [Color drop-out] on the [Image processing] tab sheet, and that color will be enhanced in scanned images. (See “Color Drop-Out,” on p. 7-18.)
