Gets the current
glPrintf()
printing step direction. Each step direction is independent of the other,
and is treated as an 8-bit signed value. The actual step increments depends 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.
Provides an interface between the
STDIO
string-handling functions and the graphic library. The
STDIO
string-formatting function will call this function, one character at a time, until the entire format-
ted string has been parsed. Any portion of the bitmap character that is outside the LCD display area will
be clipped.
PARAMETERS
ch
is the character to be displayed on the LCD.
*ptr
is not used, but is a place holder for
STDIO
string functions.
*cnt is not used, is a place holder for
STDIO
string functions.
*pInst
is a font descriptor pointer.
RETURN VALUE
None.
