Use this tool to draw single straight line segments. When you click the Line Tool button and move the cursor over an image frame, the cursor will take shape of a cross with a straight line segment. Press the left mouse button and drag the cursor to draw the desired line. As you draw with the Line Tool, ImageWarp displays the coordinates of the starting point and the moving cursor (see Status Bar for more details). If you want to constrain a segment to a vertical or horizontal line, press the left mouse button and hold down the CTRL key while dragging the cursor. When you draw with the Line Tool, the current draw color is applied. You can select the width of the line on the Palette Bar and watch the changes in the pen width sample. If you double-click the pen width sample, the Tool Settings dialog box will appear. To select the width of the line, indicate the desired value in pixels in the Width box.
