Modes - It determines the way of creating the selection, i.e. whether it will be combined with existing one, etc.
Antialiasing - It causes the boundary of the selection to be drawn smoother.
Feather edge - It causes the boundary of the selection to be blurred.
Expand from centre - It expands the selection, using starting point as the centre, instead of the corner. After enabling this option, the starting point is used as the centre of the selection instead of using it as a corner. This also causes the selection to extend from all sides. This option can be enabled with Shift.
Fixed - It allows you to modify the actual shape of the rectangle through four available options namely, "Aspect Ratio, Width, Height, Size". It mainly focuses the shapes of an image.
Position - It is the placement of the selection.
Size - It is the size of the selection. The actual size of the current selection. You can use it to modify the size, as well as resize it directly on the image.
Highlight - It highlights the actual selection, by darkening everything that surrounds it. Emphasizes the selected area by a surrounding mask, making the visual selection much easier.
Guides - It picks the types of guides that are shown within the selection in-order to make the selection easier. The options available under guide are "No guides, center lines, Rule of thirds, Golden sections". It adopts the photo composition rules.
Auto Shrink - It shrinks the selection to the nearest ellipse shape available on the image layer. Select a portion in the image and then apply this option, which will shrink to the nearest rectangular shape within the selection.
The algorithm for finding the best rectangle, can once do a great work, and sometimes find some strange rectangles.
Shrink merged - If this option is enabled, then Auto Shrink will use the pixel information from the visible display of the image, rather than from the active layer. If this option is enabled Auto shrink will look on the actually visible image, rather than the active layer.
