|
Constructor. The data buffer and table describing the TIFF structure of the data are set in the constructor.
|
|
Read deferred components. This function is called after the TIFF composite is read by passing a TiffReader to the accept() function of the root component. It reads all components for which reading was deferred during that pass. This is usually done to make sure that all other components are accessible at the time the deferred components are processed. |
