Common parameter types#

The VGLite graphics API uses a naming convention scheme wherein definitions are preceded by vg_lite.

Below is the list of types and structures in the driver implementation.

Name	Typedef	Value
vg_lite_bool_t	int	A signed 32-bit integer 0: FALSE; 1: TRUE.
vg_lite_int8_t	char	A signed 8-bit integer
vg_lite_uint8_t	unsigned char	An unsigned 8-bit integer
vg_lite_int16_t	short	A signed 16-bit integer
vg_lite_uint16_t	unsigned short	An unsigned 16-bit integer
vg_lite_int32_t	int	A signed 32-bit integer
vg_lite_uint32_t	unsigned int	An unsigned 32-bit integer
vg_lite_uint64_t	unsigned long long	An unsigned 64-bit integer
vg_lite_float_t	float	A 32-bit single precision floating point number
vg_lite_double_t	double	A 64-bit double precision floating point number
vg_lite_char_t	char	A signed 8-bit integer
vg_lite_string	char*	A pointer to a character string
vg_lite_pointer	void*	A generic address pointer (void *). On 32-bit OS, it is a 32-bit address pointer. On 64-bit OS, it is a 64-bit address pointer.
vg_lite_void	void	The void type
vg_lite_color_t	vg_lite_uint32_t	A 32-bit color value The color value specifies the color used in various functions. The color is formed using 8-bit RGBA channels. The red channel is in the lower 8-bit of the color value, followed by the green and blue channels. The alpha channel is in the upper 8-bit of the color value. For L8 target formats, the RGB color is converted to L8 by using the default ITU-R BT.709 conversion rules.
VG_LITE_S8	enum vg_lite_format_t	A signed 8-bit integer coordinate
VG_LITE_S16	enum vg_lite_format_t	A signed 16 bit integer coordinate
VG_LITE_S32	enum vg_lite_format_t	A signed 32-bit integer coordinate
VG_LITE_FP32	enum vg_lite_format_t	A 32-bit floating point coordinate
