tlDigitizerDX::tlDigitizerDX | ( | ) |
Prepare a digitizer for image acquisition using a given acquisition size. A subsequent call to open() will open the digitizer with the given settings.

Prepare a digitizer for image acquisition using a given acquisition size. A subsequent call to open() will open the digitizer with the given settings.
width | acquisition width | |
height | acquisition height |
tlDigitizerDX::~tlDigitizerDX | ( | ) | [virtual] |
int tlDigitizerDX::open | ( | int | index = 0 |
) | [virtual] |
Open a digitizer for image acquisition using default settings.
index | [default=0] the index of the digitizer in the system (for use of multiple digitizers at the same time) |
Implements tlDigitizer.

int tlDigitizerDX::open | ( | int | width, | |
int | height, | |||
int | index = 0 | |||
) | [virtual] |
Open a digitizer for image acquisition using a given acquisition size.
width | new acquisition width | |
height | new acquisition height | |
index | [default=0] the index of the digitizer in the system (for use of multiple digitizers at the same time) |
Reimplemented from tlDigitizer.

int tlDigitizerDX::close | ( | ) | [virtual] |
Clean up digitizer buffers and close hardware connection. Configuration is retained, so that a call to open() will restore the digitizer state to the last used mode.
Implements tlDigitizer.
References tlDigitizer::isOpen.

int tlDigitizerDX::setSize | ( | int | width, | |
int | height | |||
) | [virtual] |
Set the digitizer acquisition size. All other parameters are left untouched. Depending on the hardware, this call might close and reopen the device, possibly leading to some latency.
width | new acquisition width | |
height | new acquisition height |

int tlDigitizerDX::grab | ( | tlImage * | image | ) | [virtual] |
This call acquires a full image from an image source. The image will have the size and format the source is currently configured for.
image | [out] a valid image pointer that will receive the image. |
Implements tlDigitizer.

Referenced by grabQueued().
This call acquires a portion of an image from an image source. The image will have the size and format the source is currently configured for, but only the portion defined by the rect argument will contain valid pixel values.
image | [out] a valid image pointer that will receive the image. | |
rect | a pointer to the portion of the image to acquire. |
