◆ bfont_draw()

size_t bfont_draw	(	void *	buffer,
		uint32_t	bufwidth,
		bool	opaque,
		uint32_t	c )

Draw a single character to a buffer.

This function draws a single character in the set encoding to the given buffer. Calling this is equivalent to calling bfont_draw_thin() with 0 for the final parameter.

Parameters

buffer	The buffer to draw to (at least 12 x 24 pixels)
bufwidth	The width of the buffer in pixels
opaque	If true, overwrite blank areas with black, otherwise do not change them from what they are
c	The character to draw

Returns: Amount of width covered in bytes.

◆ bfont_draw_ex()

size_t bfont_draw_ex	(	void *	buffer,
		uint32_t	bufwidth,
		uint32_t	fg,

		uint8_t	bpp,
		bool	opaque,
		uint32_t	c,
		bool	wide,
		bool	iskana )

Draw a single character of any sort to the buffer.

This function draws a single character in the set encoding to the given buffer. This function sits under draw, draw_thin, and draw_wide, while exposing the colors and bitdepths desired. This will allow the writing of bfont characters to paletted textures.

Parameters

buffer	The buffer to draw to.
bufwidth	The width of the buffer in pixels.
fg	The foreground color to use.
bg	The background color to use.
bpp	The number of bits per pixel in the buffer.
opaque	If true, overwrite background areas with black, otherwise do not change them from what they are.
c	The character to draw.
wide	Draw a wide character.
iskana	Draw a half-width kana character.

Returns: Amount of width covered in bytes.

◆ bfont_draw_str()

void bfont_draw_str	(	void *	b,
		uint32_t	width,
		bool	opaque,

Draw a full string to a buffer.

This function draws a NUL-terminated string in the set encoding to the given buffer. This will automatically handle mixed half and full-width characters if the encoding is set to one of the Japanese encodings. Draws pre-set 16-bit colors.

Parameters

b	The buffer to draw to.
width	The width of the buffer in pixels.
opaque	If true, overwrite blank areas with bfont_bgcolor, otherwise do not change them from what they are.

		uint32_t	fg,
		uint32_t	bg,
		uint8_t	bpp,
		bool	opaque,
		const char *	str )

Draw a full string of any sort to any sort of buffer.

This function draws a NUL-terminated string in the set encoding to the given buffer. This will automatically handle mixed half and full-width characters if the encoding is set to one of the Japanese encodings. Colors and bitdepth can be set.

Parameters

b	The buffer to draw to.
width	The width of the buffer in pixels.
fg	The foreground color to use.
bg	The background color to use.
bpp	The number of bits per pixel in the buffer.
