Main DjVu Image data structure.
Main DjVu Image data structure. This class defines the internal representation of a DjVu image. This representation consists of a few pointers referencing the various components of the DjVu image. These components are created and populated by the decoding function. The rendering functions then can use the available components to compute a pixel representation of the desired segment of the DjVu image.
