Title: FIREWORKS Overview and Tips Part 10

FIREWORKS Overview and Tips Part 10
  • Prepared by Sandra T. Caceres
  • Fun Exercise 3

2
Graphic Composition
  • Computers display visual images in various
    formats.

3
Definition - Pixel
  • The pixel (a word invented from "picture
    element") is the basic unit of programmable color
    on a computer display or in a computer image.
  • Think of it as a logical - rather than a physical
    - unit.
  • The physical size of a pixel depends on how
    you've set the resolution for the display screen.
  • If you've set the display to its maximum
    resolution, the physical size of a pixel will
    equal the physical size of the dot pitch (let's
    just call it the dot size) of the display.
  • If, however, you've set the resolution to
    something less than the maximum resolution, a
    pixel will be larger than the physical size of
    the screen's dot (that is, a pixel will use more
    than one dot).

4
Bitmaps
  • A bit map (often spelled "bitmap") defines a
    display space and the color for each pixel or
    "bit" in the display space. It is the method of
    storing information that maps an image pixel, bit
    by bit
  • Visualize the paint by number hobby kits. That
    analogy should help you visualize an image in
    bits.
  • Most image files are bit mapped.
  • Bitmap images are used by all computers. The
    desktop or screen information for all Windows
    machines uses .bmp files, while the Macintosh
    uses pict files.
  • This type of file gives you the jaggies, when
    examined closely you can see the line of pixels
    that create jagged edges rather than smooth
    lines.
  • There are many bitmapped file formats, .bmp,
    .pcx, .pict, .pict-2, tiff, .tif, .gif, jpeg, and
    so on.

5
  • A Graphics Interchange Format and a JPEG are
    examples of graphic image file types that contain
    bit maps.
  • A bit map does not need to contain a bit of
    color-coded information for each pixel on every
    row. It only needs to contain information
    indicating a new color as the display scans along
    a row. Thus, an image with areas of solid color
    will tend to require a small bit map.
  • Because a bit map uses a fixed or raster graphics
    method of specifying an image, the image cannot
    be immediately rescaled by a user without losing
    definition.

6
  • As you will recall from the first Fireworks
    exercise, a vector graphics graphic image, is
    designed to be quickly rescaled. Typically, an
    image is created using vector graphics and then,
    when the artist is satisfied with the image, it
    is converted to (or saved as) a raster graphic
    file or bit map.

A symbol that looks like a corner appears,
(insertion pointer) place it at the top left of
the canvas. A blue line surrounds the picture
that is imported.
You cant see the symbol there.

The picture fills the canvas.

Fireworks Exercise 1
  • With this visual review and information you have
    a guide to help with Fireworks Practice Exercise
    1.
  • The instructions for Practice Exercise 1are brief
    and you will need this PowerPoint to provide the
    examples.
  • Go to the Homepage and click on Fireworks
    Practice, select the files under the heading of
    Practice Exercise 1.
  • Once you have completed Practice Exercise 1, go
    to the Fireworks Discussion and tell your
    classmates what you learned.
