| tlDigitizerV4L::tlDigitizerV4L | ( | int | width, | |
| int | height | |||
| ) |
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 |
| tlDigitizerV4L::tlDigitizerV4L | ( | int | width, | |
| int | height, | |||
| int | channel, | |||
| unsigned short | input = TL_SOURCE_AUTO | |||
| ) |
Prepare a digitizer for image acquisition using a given acquisition size and specific acquisition channel. A subsequent call to open() will open the digitizer with the given settings.
| width | new acquisition width | |
| height | new acquisition height | |
| channel | channel index on the digitizer | |
| input | acquisition channel video format |
| int tlDigitizerV4L::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 tlDigitizerV4L::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 tlDigitizerV4L::open | ( | int | width, | |
| int | height, | |||
| int | index, | |||
| int | channel, | |||
| unsigned short | input = TL_SOURCE_AUTO | |||
| ) |
Open a digitizer for image acquisition using a given acquisition size and a specific acquisition channel.
| width | new acquisition width | |
| height | new acquisition height | |
| channel | channel index on the digitizer | |
| input | input channel video format | |
| index | [default=0] open device at a specific index (for use of multiple devices) |
| int tlDigitizerV4L::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.
| int tlDigitizerV4L::setChannel | ( | int | channel, | |
| unsigned short | input | |||
| ) | [virtual] |
Set the acquisition channel.
| channel | channel index on the digitizer | |
| input | input video format |
Reimplemented from tlDigitizer.
| int tlDigitizerV4L::setInput | ( | unsigned short | input | ) | [virtual] |
Set the acquisition channel input format.
| input | input channel video format |
Reimplemented from tlDigitizer.
| int tlDigitizerV4L::setFrameRate | ( | int | fps | ) | [virtual] |
Set the frame rate of the DirectX compatible digitizer.
| fps | frame rate [frame per second] |
Reimplemented from tlDigitizer.
| int tlDigitizerV4L::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 |
Reimplemented from tlDigitizer.
| int tlDigitizerV4L::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.
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. |
Implements tlDigitizer.
| int tlDigitizerV4L::grabQueued | ( | 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.
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. |
Implements tlDigitizer.
| tlDigitizer::getInput | ( | ) | [inline, inherited] |
| tlDigitizer::getChannel | ( | ) | [inline, inherited] |
Get currently selected input channel.
| tlSource::getWidth | ( | ) | [inline, inherited] |
Returns the width of the image source. Any image acquired through this tlSource object will have the current width.
| tlSource::getHeight | ( | ) | [inline, inherited] |
Returns the height of the image source. Any image acquired through this tlSource object will have the current height.
| tlSource::getID | ( | ) | [inline, inherited] |
Return a unique identifier for this source. Identifiers are allocated dynamically and are only valid during application run-time.
| tlSource::getFormat | ( | ) | [inline, inherited] |
tlDigitizer::isOpen [protected, inherited] |
Return the current state of the digitizer.
