pylon/PixelTypeMapper.h

Pixeltypemapper for mapping GenICam pixel format enumerations to pylon pixel type enumeration.

Namespaces

Name
Pylon Contains definitions of pylon types.

Classes

	Name
class	Pylon::CPixelTypeMapper A simple pixeltypemapper (maps device specific pixelformats read from device-node map to pylon pixeltypes by their name).
class	Pylon::CCameraPixelTypeMapperT A camera specific pixeltypemapper (maps device specific pixelformats contained in the generated camera classes to pylon pixeltypes by their name).
