Creating a new document 17
When you edit a bitmap graphic, you modify pixels rather than lines and curves. These
bitmap graphics are resolution-dependent, which means that the data describing the image is
fixed to a grid of a particular size. Enlarging a bitmap graphic redistributes the pixels in the
grid, often making the edges of the image appear ragged. Displaying a bitmap graphic on an
output device with a lower resolution than the image itself can also degrade the image’s
quality.
Creating a new document
When you select File > New to create a new document in Fireworks, you create a Portable
Network Graphic, or PNG document. PNG is the native file format for Fireworks. After you
create graphics in Fireworks, you can export or save them in other familiar web graphic
formats, such as JPEG, GIF, and animated GIF. You can also export or save graphics in many
of the popular formats used off the web, such as TIFF and BMP. Whatever optimization and
export settings you choose, the original Fireworks PNG file is preserved to allow easy editing
later.
To create a web graphic in Fireworks, you must first set up a new document or open an
existing one. You can adjust the setup options later in the Property inspector.
To create a new document:
1.
Select File > New.
The New Document dialog box opens.
2. Enter the canvas width and height measurements in pixels, inches, or centimeters.
3. Enter a resolution in pixels per inch or pixels per centimeter.
