The Radiant Line Tool is used to draw lines from a center point to form star bursts and elaborate designs. To use this tool, move the mouse cursor to the location in your picture where you want to start the design (the lines will radiate from this point). Next, click and hold the mouse button and drag to form the first line of the design. When the line reaches the correct length and position, release the button and move the cursor around the axis to form your design. To stop drawing and complete the design, click the mouse button once more.
The left mouse button will draw the line using the color on the left side of PixelNEO's Color Box. The right mouse button will draw the line with the color on the right side of the Color Box.
