glSetPfStep
void glSetPfStep(int stepX, int stepY);
DESCRIPTION
Sets the
glPrintf()
printing step direction. The
x
and
y
step directions are indepen-
dent signed values. The actual step increments depend on the height and width of the
font being displayed, which are multiplied by the step values.
PARAMETERS
stepX
the
glPrintf
x
step value
stepY
the
glPrintf
y
step value
RETURN VALUE
None.
SEE ALSO
Use
glGetPfStep()
to examine the current
x
and
y
printing step direction.
glGetPfStep
int glGetPfStep(void);
DESCRIPTION
Gets the current
glPrintf()
printing step direction. Each step direction is indepen-
dent of the other, and is treated as an 8-bit signed value. The actual step increments de-
pends on the height and width of the font being displayed, which are multiplied by the
step values.
RETURN VALUE
The
x
step is returned in the MSB, and the
y
step is returned in the LSB of the integer
result.
SEE ALSO
Use
glGetPfStep()
to control the
x
and
y
printing step direction.
