Chapter 13. Graphics

Linux has graphics tools for the most common graphics needs:

  • Pictures: Applications can create and edit graphic files containing digital imagespictures. You can create the pictures in the graphic application or you can edit a picture contained in another file. For instance, you can edit a picture taken with a digital camera or scanned by a scanner. On Linux, the most powerful, full-featured application for creating or editing pictures is the GIMP (GNU Image Manipulation Program). The GIMP offers similar functionality to Photoshop.

  • Diagrams: Drawings comprised of shapes and lines connecting the shapes. Organizational charts and network diagrams are composed of shapes and lines. Dia is a diagramming program, similar to Visio.

  • Drawings: Drawings are line art, usually just black and white. Cartoons and logos are commonly made with a drawing application. OpenOffice provides an application called Draw that allows you to create and edit drawings. You can draw directly in OpenOffice documents, as described in Chapter 11. Or, you can export drawings made using Draw in general graphics formats that can be used by other graphics applications.

  • Presentation Graphics: Creating slides that accompany talks and presentations is a common use of graphics. OpenOffice provides the Impress application for creating slides, comparable to using PowerPoint in MS Office.

The source of your graphics can be original art or drawings that you create. It can also be photographs that you take yourself. If you are using art or photographs originated by someone else, you need to be sure you can legally use the picture. Pictures are copyrighted by default and can't be used without permission.

Archives of pictures are available on the Web. Some pictures need to be purchased; some are free. You need to read the information accompanying any pictures you wish to use. If explicit permission is not provided for public use, you need to get specific permission from the copyright owner.
