7.3 painting and Drawing tools

Painting and drawing tools, as well as 3D modellers, are perhaps the most important items in
the toolkit because, of all the multimedia elements, the graphical impact of the project will likely
have the greatest influence on the end user. If the artwork is amateurish, or flat and uninteresting,
both the creator and the users will be disappointed.
Painting software such as Photoshop, Fireworks, and Painter, is dedicated to producing crafted
bitmap images. Drawing software, such as CorelDraw, FreeHand, Illustrator, Designer, and Canvas,
is dedicated to producing vector-based line art easily printed to paper at high resolution.
Some software applications combine drawing and painting capabilities, but many authoring
systems can import only bitmapped images. Typically, bitmapped images provide the greatest
choice and power to the artist for rendering fine details and effects, and today bitmaps are used
in multimedia more often than drawn objects. Some vector based packages such as Macromedia’s
Flash are aimed at reducing file download times on the Web, and may contain both bitmaps and
drawn art. The anti-aliased character shown in the bitmap of Color Plate 5 is an example of the
fine touches that improve the look of an image.

Look for these features in a drawing or painting packages:
• An intuitive graphical user interface with pull-down menus, status bars, palette control,
and dialog boxes for quick, logical selection.

• Scalable dimensions, so you can resize, stretch, and distort both large and small bitmaps.
• Paint tools to create geometric shapes, from squares to circles and from curves to complex
polygons.
• Ability to pour a colour, pattern, or gradient into any area.
• Ability to paint with patterns and clip art.
• Customizable pen and brush shapes and sizes.

• Eyedropper tool that samples colours.
