Definition at line 655 of file firewire.cpp.

References _auto_white_balance.

unsigned char * FirewireCamera::buffer (  )  [virtual]

Get access to current image buffer.

This will return a pointer to the current buffer. The buffer contains an image of the given colorspace, width and height.

Returns:
pointer to image buffer

Implements Camera.

Reimplemented in Bumblebee2Camera.

Definition at line 347 of file firewire.cpp.

References _frame, and _valid_frame_received.

unsigned int FirewireCamera::buffer_size (  )  [virtual]

Gets the size in bytes of the buffer returned by buffer().

Returns:
size of buffer in bytes

Implements Camera.

Definition at line 358 of file firewire.cpp.

References _frame, and _valid_frame_received.

void FirewireCamera::capture (  )  [virtual]

Capture an image.

Although cameras shall operate with a continuous image flow where possible sometimes capturing an image means copying a buffer or advancing a buffer list pointer. This shall be done in this method. For a camera-using application it is mandatory to call capture() just before accessing the image buffer.

Some cameras need disposal of the current buffer (for example to free space in a queue to retrieve the next image). This is done with this method. It has to be called after all work has been done on the image as desired. After dispose_buffer() has been called no further access may happen to the image buffer or undesired behavior may happen.
