Use this tool to select an irregularly shaped area in the active image frame. When you click the Freehand Selection Tool button and move the cursor over an image frame, the cursor will take shape of a cross with a lasso. To draw a freehand selection, position the center of the cross where you want the starting point of the selection to be, and drag the cursor to draw the desired selection. As you draw the selection, ImageWarp displays the coordinates of the starting point and the moving cursor, as well as the sizes of the bounding rectangle for the current selection (see Status Bar for more details). To draw a polygon, position the center of the cross where you want the starting point of the selection to be, click the left mouse button to anchor the starting point and move the cursor, clicking the mouse button every time you want to set a new anchor point. You can combine freehand curves with straight lines by holding the mouse button and clicking it. To complete a freehand selection, double-click the left mouse button. If you want to constrain the polygon's sides to vertical or horizontal lines, hold down the CTRL key while moving the cursor. If you make a mistake, press the BACKSPACE key to remove the last segment. You can also press the BACKSPACE key repeatedly or hold it down until you've erased the desired segment. Pressing the ESC key while drawing a freehand selection will cancel the whole action. To remove a current selection, double-click in any place of the image.
To add an additional freehand area to a current selection, hold the SHIFT-key. The cursor will take a shape of a cross with a lasso and a small "+" sign next to it. Use the described procedure to define a new freehand area. When you release the mouse button, a new selection will be added to the current one and the selection marquee will be rearranged to outline the combined selection area.
To subtract a freehand area from a current selection, hold the ALT-key. The cursor will take a shape of a cross with a lasso and a small "-" sign next to it. Use the described procedure to define a negative freehand area. When you release the mouse button, a new selection will be subtracted from the current one and the selection marquee will be rearranged the resulting selection area. If you create a negative selection area on an image with no current selection, a full-size rectangular selection will be automatically created and the defined negative region will become "a hole" in it.
Note that these operations neither affect the image, nor change a Standard Selection to a Floating Selection. See Working with Selections for more details.
