ADOBE PHOTOSHOP CS2 

The Magnetic Pen is an option of the Freeform Pen tool that lets you draw a path that snaps to the edges of defined 
areas in your image. You can define the range and sensitivity of the snapping behavior, as well as the complexity of 
the resulting path. The Magnetic Pen and Magnetic Lasso tools share many of the same options. 

To convert the Freeform Pen tool to the Magnetic Pen tool 

, select Magnetic in the options bar, or click the 

inverted arrow next to the shape buttons in the options bar, select Magnetic, and set the following: 

For Width, enter a pixel value between 1 and 256. The Magnetic Pen detects edges only within the specified 
distance from the pointer. 

For Contrast, enter a percentage value between 1 and 100 to specify the contrast required between pixels for that 
area to be considered an edge. Use a higher value for low-contrast images. 

For Frequency, enter a value between 0 and 100 to specify the rate at which the Pen sets anchor points. A higher 
value anchors the path in place more quickly. 

If you are working with a stylus tablet, select or deselect Pen Pressure. When this option is selected, an increase in 
pen pressure causes the width to decrease. 

Click in the image to set the first fastening point. 

To draw a freehand segment, move the pointer or drag along the edge you want to trace. 

The most recent segment of the border remains active. As you move the pointer, the active segment snaps to the 
strongest edge in the image, connecting the pointer to the last fastening point. Periodically, the Magnetic Pen adds 
fastening points to the border to anchor previous sections. 

If  the border doesn’t  snap  to  the desired  edge, click  once  to  add a fastening point  manually  and to keep the  border  

from moving. Continue to trace the edge and add fastening points as needed. If you make a mistake, press Delete to 
remove the last fastening point.
