Use the Rotate and Crop Picture - Fabric page of the Background Assistant to prepare a fabric sample picture when creating a background.
Initially, about half the area of the picture is selected from the middle of the picture, as shown by the dashed box in the picture on the left. The preview on the right shows four copies of the selected fabric area tiled together. The tiled preview changee dynamically as you change the crop area.
To adjust the crop area, position the mouse over the crop boundary until a double-headed arrow
appears, then drag to move the boundary line.
To move the crop area, position the mouse inside the crop boundary until a hand pointer
appears, then drag to move the whole rectangle.
To redraw the crop area, drag outside the crop boundary to draw a new rectangle, which can then be adjusted as required.
To see where the four sections of the background are joined, select the Show Divider option. Dashed lines show where the tiled sections are joined. This is useful for patterned fabric, to ensure the pattern repeats as desired.
When the desired area is selected, click Next.
Rotate
the picture from 0 to 359 degrees. Adjust the picture angle as desired. This is often necessary with scanned pictures.
Enter the desired Rotation angle
or use the up/down arrows to change the angle. The preview will show the effect.
Note: When the picture is rotated between the 90 degree steps, the picture is made larger and white background is added.
Use Select All to select the whole of the picture. Use Automatic to set the crop lines back to the default position for the current picture.
To remove the effects of perspective in a picture, or to correct skew, select Perspective Correction . When using Perspective Correction, the crop handles are red.
Drag the red handles so that the crop lines frame the picture. Use the Zoom tools to view the outline of the picture more clearly. Drag the Stretch Picture slider to make the picture in the Preview wider or narrower. Use Save Picture to save your edited picture.
Use the Zoom bar to change the view of the picture. Zoom in (drag the slider to the right) to magnify the view. Zoom out (drag the slider to the left) to shrink the view.
When zoomed in, use the scroll bars or swipe to move around.
