## Abstract

An image processing apparatus includes a reading unit configured to read a document to generate a document image, a determination unit configured to determine whether rotation processing for rotating the document image is to be performed when printing is performed based on the document image, and a display unit configured to display a print preview representing a printed result, wherein the display unit displays the print preview if the determination unit determines that the rotation processing is to be performed.

## Claims

### Claim 1

An image processing apparatus comprising:
a reading unit configured to read a document to generate a document image;
a determination unit configured to determine whether rotation processing for rotating the document image is to be performed when printing is performed based on the document image; and
a display unit configured to display a print preview representing a printed result,
wherein the display unit displays the print preview if the determination unit determines that the rotation processing is to be performed.

### Claim 2 (depends on 1)

The image processing apparatus according to claim 1, further comprising a setting unit configured to set aggregate printing for aggregating a plurality of document images to one sheet and printing the aggregated document images thereon,
wherein the display unit displays the print preview if the determination unit determines that the rotation processing is to be performed and the setting unit sets the aggregate printing.

### Claim 3 (depends on 1)

The image processing apparatus according to claim 1, further comprising a printing unit configured to perform printing based on the document image.

### Claim 4 (depends on 3)

The image processing apparatus according to claim 3, wherein the display unit displays the print preview before the printing unit performs the printing, and
wherein the printing unit performs the printing in response to a printing instruction input by a user when the display unit is displaying the print preview.

### Claim 5 (depends on 3)

The image processing apparatus according to claim 3, wherein the printing unit performs the printing, without the display unit displaying the print preview, if the determination unit determines that the rotation processing is not to be performed.

### Claim 6 (depends on 1)

The image processing apparatus according to claim 1, wherein the display unit displays the print preview if an instruction for displaying the print preview is input by a user even if the determination unit determines that the rotation processing is not to be performed.

### Claim 7

A method for controlling an image processing apparatus, the method comprising:
reading a document to generate a document image;
determining whether rotation processing for rotating the document image is to be performed when printing is performed based on the document image; and
displaying a print preview representing a printed result if it is determined that the rotation processing is to be performed.

### Claim 8 (depends on 7)

A computer-readable storage medium storing a program that causes a computer to perform the method according to claim 7.
