The invention discloses a method and a device for typesetting an electronic document, belonging to the field of information display. The method comprises the following steps of: analyzing the electronic document, extracting paragraph marks and displaying the electronic document; when carrying out scaled typesetting operation on the current page, marking an initial word block in the current page; forwards or backwards refreshing all word blocks beginning from the marked initial word block; scaling, typesetting and displaying the word blocks displayed in the current page and marking a final word block of the current page after scaled typesetting; carrying out scaled typesetting on the electronic document from an initial character of the document; and when displaying the next page or the previous page of the current page after the scaled typesetting, displaying the electronic document after the scaled typesetting from the initial character of the document. In the invention, when the character scaling is carried out on the current page, the whole document is scaled from the initial character of the document, and the document content with scaled characters is typesetted again, therefore, the page display speed after the displayed characters are scaled is accelerated, and the waiting time of a user when the word size is scaled is shortened.
Description
technical field [0001] The present invention relates to the field of information display, in particular to an information display device and method, in particular to an electronic document typesetting method and device. Background technique [0002] Along with the continuous popularization of electronic reading devices, many people who love to read use electronic reading devices to read. The bistable display using electronic ink technology only consumes power when the user turns pages to refresh. It has the characteristics of low power consumption and good display effect, and can also display with high brightness under strong light. Therefore, electronic reading devices using such display screens are very popular among users. [0003] Currently, an editable electronic document in an e-reader usually provides a font zoom display function when typesetting and displaying, and adopts font scaling to start typesetting according to the first character of the electronic document a...
