CHAPTER 4
Working with Bitmaps
Bitmaps are graphics composed of small colored squares called pixels, which combine like the
tiles of a mosaic to create an image. Examples of bitmap graphics include photographs,
scanned images, and graphics created from paint programs. They are sometimes referred to
as
raster images .
Macromedia Fireworks 8 combines the functionality of photo-editing, vector-drawing, and
painting applications. You can create bitmap images by drawing and painting with bitmap
tools, by converting vector objects to bitmap images, or by opening or importing images.
Fireworks has a powerful set of Live Filters for tone and color adjustment, as well as a number
of ways to retouch your bitmap images, including cropping, feathering, and duplicating or
cloning images. In addition, Fireworks has a set of image-retouching tools—Blur, Sharpen,
Dodge, Burn, and Smudge.
For information on methods for selecting and transforming images and pixel areas, see
Chapter 3, “Selecting and Transforming Objects,” on page 51 .
