I was writing. In addition, in a frame in which a graphic is described (hereinafter, a frame in which a graphic is described is called a graphic frame, and a frame in which a mathematical expression is similarly described) is a character string together with the graphic in the graphic frame. A "text frame" that can be described can be secured. Further, the graphic frame can have a text frame and a graphic frame as lower data.
That is, the text frame and the graphic frame can be defined as the frame within the graphic frame. (Hereinafter, the frame inside the frame is referred to as the frame inside frame.) You can also add a "outside frame text area" area to the figure frame or formula frame, and you can add a title etc. to the figure frame or formula frame in the document. Can be described.

As a conventional technique related to such editing of an electronic document, for example, Japanese Patent Laid-Open No. 5-2475 discloses a set of document parts of an existing electronic document and a logical structure.
An electronic document processing device for automatically generating a set of document parts and a logical structure of a new electronic document is described.
