Graphics software features

Graphics Programs, Continued Vector mapped software programs 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 program. Graphics Drafting, drawing, and painting are distinctly different functions and not all software programs will be equally adept at processing all three. Base your choice of features 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 associated affects. Continued on next page 3-34
