Graphics Programs, Continued
Vector mapped software is ideal for drawings, charts, graphs, and diagrams.
It creates an image by defining line, position, shape, and fill pattern. You
plot or vector a series of points to define a shape. This shape is calculated
into a mathematical formula called an algorithm. Image manipulation and
editing is automatically calculated by the computer when you change
parameters, making modifications easy and fast. The use of a vector-based
program requires preplanning and more computer savvy than a bit mapped
Drafting, drawing, and painting are distinctly different functions and not all
programs will be equally adept at processing all three. Base your choice of
program on command requirements. Also, let your software drive your
hardware. Select a software program that fulfills the needs of the command
and allows for some growth. Purchase hardware based on software
requirements. Invest in the very best monitor possible. All of this affects the
graphics resolution, the ease of processing, and the end product. In general,
graphics software programs offer the following features:
FILL: Fill is a command to fill a shape with color or pattern. Make sure the
shape is completely closed or the fill will bleed into the adjacent area. Color
or pattern selection is nearly limitless.
BELZIER CURVES: The axis of a Belzier curve automatically changes as
you move the cursor or mouse across the screen.
GEOMETRIC SHAPES: These are closed shapes whose major and minor
axis change with the movement of the cursor or mouse.
DELETE: Use a geometric shape to surround or isolate segments you want
removed from the image and click into place. Then press the DELETE key
to remove everything inside the geometric shape.
UNDO: UNDO is a feature that eliminates the last command given and its
