Graphics

A graphic resource (or GOCA resource) is a Graphics Object Content Architecture (GOCA) object stored as a resource in the page segment library. Graphic resources are soft resources.

Graphic data contains commands to draw lines, arcs, and circles and can be used to represent something as complex as a three-dimensional engineering drawing. It is created by a program and stored in a set of MO:DCA-P structured fields called a GOCA object. This object can then be stored as a resource for easier use.

Along with drawing commands, a graphics object can contain image and character data. Whenever image data is included in a graphics object, code the Image Resolution field in the Graphics Data Descriptor (GDD) to provide image resolution information to the printer, which lets the printer print the image at the correct size. When character data is included in a graphic, all fonts used must be mapped in the print data set or overlay or page segment that includes the graphic data object.

Figure 18 shows the graphic data printed on the sample page.
