Abstract

The invention is suitable for the technical field of application of electronic books and provides a method and system for displaying a PDF (Portable Document Format) document adaptively to a window size, and a mobile terminal. The method comprises the following steps of: A, extracting a locally-stored PDF document and selecting the range of pages to be resolved from the locally-stored PDF document; B, resolving information in the selected page range according to a preset resolving object type to obtain attribute information of each resolving object, wherein the attribute information of each resolving object comprises the position information of each resolving object; C, typesetting each resolving object according to corresponding position information of each resolving object; and D, writing the typeset resolving objects into a document which can support word wrap in a text stream write-in mode, and displaying information in the document. By adopting a PDF document displaying technology provided by the invention, a PDF page can be read without adjusting a display window leftwards or rightwards, and better reading experience and great convenience can be brought to a user.

Description

technical field [0001] The invention belongs to the technical field of e-book applications, and in particular relates to a PDF document display method, system and mobile terminal with an adaptive window size. Background technique [0002] With the massive popularization of mobile terminals, the demand for reading PDF documents on them is increasing day by day. Due to the limitation of the format of the PDF document itself, it cannot be automatically typeset according to the window size of the mobile terminal, so people need to frequently pull the scroll bar to move the page when reading to see the full page information. Therefore, how to extract the information in the PDF document, rearrange the typesetting to adapt to the size of the device window, and make it easier for people to read has become an urgent need. [0003] For the above technical problems, there are the following two solutions in the prior art: [0004] 1. Extract one page of PDF page information for displa...
