uint32_t fosgra_color_get	(	fosfat_t *	fosfat,
		const char *	path,
		uint8_t	idx
	)

Get the color RGB24 from a .COLOR index.

Parameters

[in]	fosfat	disk handle.
[in]	path	location on the FOS disk.
[in]	idx	color index in map.

Returns

the color in RGB24.

uint8_t* fosgra_get_buffer	(	fosfat_t *	fosfat,
		const char *	path,
		int	offset,
		int	size
	)

Get decoded .IMAGE buffer.

Parameters

[in]	fosfat	disk handle.
[in]	path	location on the FOS disk.
[in]	offset	from where (in bytes) in the data.
[in]	size	how many bytes.

Returns

NULL if error or return the buffer.

void fosgra_get_info	(	fosfat_t *	fosfat,
		const char *	path,
		uint16_t *	x,
