Graphics Programs, ContinuedVector mappedsoftwareprogramsVector mapped software is ideal for drawings, charts, graphs, and diagrams.It creates an image by defining line, position, shape, and fill pattern. Youplot or vector a series of points to define a shape. This shape is calculatedinto a mathematical formula called an algorithm. Image manipulation andediting is automatically calculated by the computer when you changeparameters, making modifications easy and fast. The use of a vector-basedprogram requires preplanning and more computer savvy than a bit mappedprogram.GraphicsDrafting, drawing, and painting are distinctly different functions and not allsoftwareprograms will be equally adept at processing all three. Base your choice offeaturesprogram on command requirements. Also, let your software drive yourhardware. Select a software program that fulfills the needs of the commandand allows for some growth. Purchase hardware based on softwarerequirements. Invest in the very best monitor possible. All of this affects thegraphics 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 theshape is completely closed or the fill will bleed into the adjacent area. Coloror pattern selection is nearly limitless.BELZIER CURVES: The axis of a Belzier curve automatically changes asyou move the cursor or mouse across the screen.GEOMETRIC SHAPES: These are closed shapes whose major and minoraxis change with the movement of the cursor or mouse.DELETE: Use a geometric shape to surround or isolate segments you wantremoved from the image and click into place. Then press the DELETE keyto remove everything inside the geometric shape.UNDO: UNDO is a feature that eliminates the last command given and itsassociated affects.Continued on next page3-34
