		int	row,
		int	col
	)

Move (imaginary) cursor to column and row specified.

Definition at line 72 of file text.c.

uint8_t text_style	(	struct Bitmap *	bm,
		uint8_t	flags,
		uint8_t	mask
	)

Set/clear algorithmic font style bits.

Parameters:

	bm	Pointer to Bitmap to affect.
	flags	Style flags to set
	mask	Mask of flags to modify

Returns:

Old style flags

Examples: Turn on bold, leave other styles alone

 text_style(bm, STYLEF_BOLD, STYLEF_BOLD); 

Turn off bold and turn on italic, leave others as they are

 text_style(bm, STYLEF_ITALIC, STYLEF_BOLD | STYLEF_ITALIC); 

Query current style without chaning it

 style = text_style(bm, 0, 0); 

Reset all styles (plain text)

 text_style(bm, 0, STYLE_MASK);
