The Page Curl dialog box opens, indicating that you will choose to bend the image at any corner through the 4 left middle icons.Direction area allows you to choose the direction of bending angle in the direction of straight up ( Vertical ) or horizontal ( Horizontal ). In the Paper area, you can give your flip angle opaque ( Opaque ) or ( Transparent ). The Color area shows you the color of the flip angle ( Curl ) and the color of the background ( Background ) by selecting the color in the 2 color cells. The two Width% and Height% sliders below allow you to set parameters to 'flip' the corners of the image. If you extend the angle of the corner of the image, it is the percentage value of the width. Height is the value from the top of the flip angle when it has not turned to the corner of the flip. Also, if you want to find the same color as one of the main colors, use the Eyedropper tool located next to the 2 color boxes to select (see Figure 1).
