Chapter 2 Command Codes
Summing the values determines the data for each column of the
logo. Figure 3 shows the decimal value sums for each data byte
(column) for the arrow pattern illustrated. Each byte was
calculated first in decimal and then converted to the equivalent
hexadecimal value (using the ASCII chart in Appendix A). These
hexadecimal values are then entered in the
data parameter for
the Q command
.
Figure 3. Graphics Logo Plot Data Format
Example 2 The sample command below illustrates the logo function, drawing
the arrow shown in Figure 3. The six hex data values for each 0.1
inch x 0.1 inch matrix are repeated and horizontal tabs and
justification commands are used to produce the large arrow using
the small arrow pattern. Notice that an alphanumeric command
was required for logo positioning.
