Character direction is the direction in which the characters in a string are drawn in relation to the baseline. By default, the characters are drawn from left to right. An application can change the direction using GpiSetCharDirection. GpiSetCharDirection accepts as input one of the four values illustrated in the following figure. The value CHDIRN_DEFAULT is identical to CHDIRN_LEFTRIGHT.

An application can determine the current character direction using GpiQueryCharDirection.
