Figure 20 shows the Graphic Block Area Position control specifying the top left reference point for the
graphic block area.

Figure 20. Graphic Block Area Position Control and the Graphic Block Area

Byte A of the GAP specifies the reference coordinate system. The reference coordinate system used for
determining the top left corner of the graphic block area can be either the media X,Y or the I,B coordinate
system.
If byte A equals X'00', the absolute I and B coordinates determine the top left corner. GAP bytes 4 and 5
specify the text inline coordinate. GAP bytes 6 and 7 specify the text baseline coordinate.
If byte A equals X'20', the absolute I and relative B coordinates determine the top left corner. GAP bytes 4
and 5 specify the text inline coordinate. GAP bytes 6 and 7 add to the last text baseline coordinate
position used prior to graphics.
If byte A equals X'40', the relative I and absolute B coordinates determine the top left corner. GAP bytes 4
and 5 add to the last text inline coordinate position used prior to graphics. GAP bytes 6 and 7 specify the
text baseline coordinate.
If byte A equals X'60', the relative I and B coordinates determine the top left corner. GAP bytes 4 and 5
add to the last text inline coordinate position used prior to graphics. GAP bytes 6 and 7 add to the last text
baseline coordinate position used prior to graphics.
