About Bitmap Images and Vector Graphics

Photoshop Elements’ painting and drawing tools render artwork in two fundamentally different ways.

The painting tools, including all the varied fills, gradients, brushes, and erasers, work by making changes to pixels—adding them, removing them, or changing their color. A bitmap image is composed entirely of tiny pixels, and digital photos, the mainstay of Photoshop Elements, are bitmap images. Although you can apply paintbrushes, color fills, special effects, and filters to bitmaps, they simply don’t resize well. If you try to enlarge a digital photo, for example, you’ll see that its image quality suffers as the pixels get bigger, resulting in a blurry mess.
