Public Member Functions

• virtual bool closeFrame ()

  Close this frame.
  

• virtual bool closeLayer ()=0

  Close this layer.
  

• virtual Layer getLayerProperties (int i) const

  which properties would this grabber want from layer nr. i ?
  

• virtual unsigned getNumberOfLayers ()

  How many layers does this grabber want? This function indicates a new frame to be rendered.
  

• virtual unsigned horizontal_alignment () const

  Horizontal bit-alignment, for instance 4 to do 32 bit alignment.
  

• virtual bool openLayer (const Size &FullSize, const Size &SizeOfThisTile, const Layer &LayerProperties)=0

  Open the output device, possibly using a certain url that has been set via setOutputName().
  

• virtual string setUrl (const string &prefixurl, const string &formatid, const MetaInfo &=MetaInfo())=0

  Setting the url to which the data should be sent. Can be a local filename, of course.
  

• virtual unsigned vertical_alignment () const

  Vertical bit-alignment, for instance 4 to do 32 bit alignment.
