When you want to add a new image or change the selection of an existing image you use the selection rectangle. It appears in the scan area of the screen and looks like this:
This is a bit different from the selection rectangles you may be used to, but this is for several reasons:
| 1. | If the rectangle is well centered on the image, but slightly tilted you can use the curved corner arrows to rotate the rectangle so that the edges of the rectangle are parallel to the edges of the photo. |
| 2. | If the rectangle is too small or too big for the photo you can change its size by dragging the edges of the rectangle (near the straight arrows). |
| 3. | If you want to pan to a completely different area of the scan you can drag the central circle. As you pan (by dragging the center of the circle) the rectangle size and angle do not change, which means that you can quickly move to similar sized and angled objects simply by panning. |
| 4. | Dragging the word "TOP" rotates the rectangle, letting you easily specify where the top of your photo is. |
You can remove the selection rectangle by hitting the ESC key on your keyboard.
You can start a new selection rectangle by dragging far from the current one. You may want to do this if the rectangle gets impossibly small:
If you want to select small areas you can use the sub image fine tuning dialog to crop your larger selection.
When you can see the selection rectangle you can use the Add command or the Substitute command by hitting the A or the S keys on your keyboard.
The selection rectangle is used for rough selection of the image. You can change size and angle of the rectangle with more accuracy using the Sub Image Fine Tuning Dialog.
