Embodiment Construction

[0017] If the above security certification is passed, the e-reader program can specifically locate the metadata content through the storage location and data length of the metadata pointed to by the metadata information item in the index table in the entire e-book file, and Read the page tree and outline directory tree objects according to the organizational structure and specifications of the metadata, and retrieve and read the specific content of all element objects in the metadata in sequence according to the content index table in the metadata structure, thus completing the e-book file creation Convert the physical model to the memory logic model, convert each page object in the memory model into a corresponding bitmap object, and draw the bitmap object obtained after the conversion on the interface to form an intuitive interface on the e-reader Page display effect.

[0018] This method invention, a very important link in the specific implementation process is exactly the ...
