Method Details

setDescription

public void setDescription(String description)

Set sink description.

Parameters:

description - Description

getError

public String getError()

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

Returns:

Error string.

setEnabled

public void setEnabled(boolean enabled)

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.

Parameters:

enabled - Enable to get new frames.
