Function Documentation

void icl::io::dc::bayer2gray	(	icl8u *	src,
		icl8u *	dst,
		int	w,
		int	h
	)

internally used bayer conversion function

void icl::io::dc::extract_image_to_2	(	dc1394video_frame_t *	f,
		dc1394color_filter_t	bayerLayout,
		core::ImgBase **	ppoDst,
		std::vector< icl8u > &	dataBuffer,
		dc1394bayer_method_t	bayerMethod
	)

extracts the given frame (in most appropiate way)

here, no desired params are necessary

dc1394_t* icl::io::dc::get_static_context

(

)

since rc9 of libdc, a libary context was introduced

bool icl::io::dc::is_dc800_capable

(

dc1394camera_t *

cam

)

returns whether the given camera supports firewire B

the results depends on the camera and the PC's firewire card

void icl::io::dc::set_iso_speed	(	dc1394camera_t *	cam,
		int	mbits
	)

sets iso transmission speed for the wrapped dc1394 context

Parameters:

cam	The dc camera
mbits	mbits value (usefull might be 800 whereby 400 is default) values that do not make sense are ignored. The current libdc library documentation lists the following available speed values: 100, 200, 400, 800, 1600, 3200. But please note, that 1600 and 3200 are not supported by any camera yet. These values are only reserved for later technologies
