Files #"DjVuText.h"# and #"DjVuText.cpp"# implement the mechanism for text in DjVuImages. This file implements annotations understood by the DjVu plugins and encoders. using: contents of TXT*# chunks. Contents of the FORM:TEXT# should be passed to {DjVuText::decode}() for parsing, which initializes {DjVuText::TXT} and fills them with decoded data. Implements support for DjVuImage hidden text.
