Detailed Description

A base class for single image reading sinks.

Constructor & Destructor Documentation

ImageSink()

wpi::cs::ImageSink::ImageSink ( )

protecteddefault

Member Function Documentation

GetError()

std::string wpi::cs::ImageSink::GetError ( ) const

inline

Get error string.

Call this if WaitForFrame() returns 0 to determine what the error is.

SetDescription()

void wpi::cs::ImageSink::SetDescription ( std::string_view description )

inline

Set sink description.

Parameters

description

Description

SetEnabled()

void wpi::cs::ImageSink::SetEnabled ( bool enabled )

inline

Enable or disable getting new frames.

Disabling will cause processFrame (for callback-based CvSinks) to not be called and WaitForFrame() to not return. This can be used to save processor resources when frames are not needed.
