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
stepY
RETURN VALUE
None.
SEE ALSO
Use glGetPfStep() to examine the current x and y printing step direction.
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.
