Photoshop: Creating A Pill Shape
Create a new document and on a New Layer,
draw out a circle with the Eliptical
Marquee Tool. Remember to hold down the Shift Key as you drag
out the circle to make it a perfect circle.
Create a New
Layer and Fill it with a color you like.
Next, drag out a Guide by clicking inside the ruler on the left
side and dragging out. Position the Guide in the middle of the circle.
(if your rulers aren't visible, click Control-R/Command-R or you
can go to View>Show Rulers.)
With the Rectangular Marquee Tool, drag out a box around the right
side of the circle. See image below.
Now, holding down Control-Alt/Command-Alt click the arrow
key to drag out the shape until you have the pill shape.
De-select once you are happy with the shape.
