6.7I-O Graphics Language™ (IOGL) in Action

6.7.1GENERAL STEPS

I-O Graphics Language™ (IOGL) can be used in many different ways. It can enhance the appearance of standard host reports through a few simple graphical elements such as lines, boxes, and circles; or it can be used to present pertinent data through charts. IOGL can even be used to create sophisticated electronic forms. However, programming with IOGL always follows the same general steps:

1.Determine which IOGL elements are needed to create the desired output (the bar chart shown below uses four different IOGL elements.)

2.Determine the printable area of the page.

3.Determine the positioning of the graphical elements relative to the top left-hand corner of the printable area.

4.PCL color printer only: Determine the order in which to print the graphical elements. The lines of the last IOGL element will overlap (and cover) the previous IOGL elements.

5.Design the graphical output, one element at a time.

6.Link the graphical output with your host application.

6.7.2TUTORIAL

The following example (Figure 6-19) shows how multiple IOGL elements interact to create a bar chart.
