Used to convert a PvBuffer to another pixel type.
To change an image's format:
- Acquire an image. See #PvStream::RetrieveBuffer.
- Create an image-format converter (#PvCudaBufferConverter object). Use
#PvCudaBufferConverter::PvCudaBufferConverter.
- Test if you can convert your image to your preferred pixel type. Use
#PvCudaBufferConverter::IsConversionSupported.
For your source pixel type, use #PvImage::GetPixelType; for your destination, select an
enumeration from PvPixelType.h.
- Create a destination PvBuffer if your later task need to be done on CPU side, or
PvCudaBuffer if on GPU side.
See #PvBuffer and #PvCudaBuffer (you define the destination image's pixel type during
this step).
- Optionally, configure options like Bayer filtering, use #SetCudaBayerFilter.
- Convert the image to the new pixel type. Use #Convert.
Consult the PvPixelType documentation in order to find which pixel types are supported as conversion destinations.

Convert a PvBuffer from one format to another, with another PvBuffer to store the output.
| [in] | aSource | The original PvBuffer. |
| [out] | aCudaDestination | The new PvCudaBuffer. |
| [in] | aEnableCudaUVM | Allow allocating CUDA UVM for conversion. |

Retrieves current optional Bayer filtering.
See #SetBayerFilter

Test if a pixel type can be converted to another type.
Converting from one pixel type to another isn't a trivial mathematical calculation - all conversions require specialized, dedicated algorithms.
The IsConversionSupported method tests if the Convert method has an available conversion algorithm.
| [in] | aSource | The original pixel type. For available pixel types, see PvPixelType.h. |
| [in] | aDestination | The new pixel type. See aSource. |
| PvResult PvCudaBufferConverter::SetCudaBayerFilter | ( | PvCudaBayerFilterType | aFilter | ) |
Set the optional Bayer filtering for this converter.
Of course, only applies if the Convert method uses a PvBuffer having a Bayer pixel type. Simply ignored otherwise.
| [in] | aFilter | The new filter settings; a PvCudaBayerFilterType enumeration. |
