Abstract: A method, non-transitory computer readable medium, and system for inferring certain texts as stylized section headings in an electronic document (ED). Stylized section headings are section headings that have unique styling distinct from the body of text below each stylized heading. In particular, the stylized section headings are identified based on styling information in the ED. Identifying stylized section headings includes grouping candidate headings based on identification of dominant styling, locating high level fragments, and repeatedly locating nested fragments from within higher level fragments. The ED may or may not include explicitly identified headings in the document.

Abstract: A method for processing an electronic document (ED) to infer a sequence of section headings in the ED. The method includes generating, by a computer processor, based on regular expression matching of a predetermined section heading pattern and a plurality of characters in the ED, a list of candidate headings in the ED; generating, by the computer processor and based on the list of candidate headings, a list of chain fragments for inferring a portion of the sequence of section headings; and generating, by the computer processor and based on predetermined criteria, the sequence of section headings by merging at least two chain fragments in the list of chain fragments.

Abstract: A method for rendering an electronic document (ED) includes: receiving a request to render the ED; initiating, by a main process thread, generation of a main display list (DL) for the ED; identifying, during generation of the main DL, a first self-contained graphical structure (SCGS) within the ED; generating, by the main process thread, a first auxiliary DL for the first SCGS; inserting a reference to the first auxiliary DL into the main DL; initiating, after completion of the first auxiliary DL, rasterization of the first auxiliary DL by a first rasterization thread; resuming, by the main process thread and during rasterization of the first auxiliary DL, generation of the main DL; and rasterizing, after completion of the main DL, the main DL based on a first pixmap generated by rasterization of the first auxiliary DL.

Abstract: A method for rendering a page including: obtaining an electronic document (ED) having: a container object with a first member and a second member; multiple shadow parameters defining a shadow of the container object; and multiple shadow parameters defining a shadow of solely the first member; determining a main bounding box surrounding the container object on the page but excluding the shadow of the first member; creating a main brush having the container object but excluding the shadow of the first member; calculating a shadow bounding box based on the main bounding box surrounding the container; creating a shadow brush by applying a shadow transformation matrix to the main brush having the container object; outputting the shadow of the first container object to a framebuffer for the page; and outputting, by processing the first member, the first member and the shadow of the first member to the framebuffer.

Abstract: A method for managing electronic documents (EDs), including obtaining an ED defining an overflowed textbox with a vertical justification, a paragraph for the overflowed textbox, and a horizontal justification of the paragraph, where the paragraph comprises a plurality of characters, generating, based on the ED, an intermediate document (ID) defining an enlarged textbox encapsulating the paragraph with the horizontal justification, calculating, using the layout engine and based on the ID, a plurality of positions of the plurality of characters within the enlarged textbox by generating an intermediate page including the enlarged textbox, calculating, based on a vertical justification of the overflowed textbox, a transformation between a point of interest (POI) associated with the enlarged textbox on the intermediate page and a reference point associated with the overflowed textbox, and generating a rendered page of the ED by applying the transformation to the plurality of positions of the plurality of character

Abstract: A method for rendering a page including: obtaining an electronic document (ED) having: a container object with a first member and a second member; multiple shadow parameters defining a shadow of the container object; and multiple shadow parameters defining a shadow of solely the first member; determining a main bounding box surrounding the container object on the page but excluding the shadow of the first member; creating a main brush having the container object but excluding the shadow of the first member; calculating a shadow bounding box based on the main bounding box surrounding the container; creating a shadow brush by applying a shadow transformation matrix to the main brush having the container object; outputting the shadow of the first container object to a framebuffer for the page; and outputting, by processing the first member, the first member and the shadow of the first member to the framebuffer.

Abstract: A method for rendering a page, including: obtaining an electronic document (ED) identifying a main object and multiple shadow parameters; determining a main bounding box surrounding the main object on the page; creating a main brush including the main object; calculating a shadow bounding box based on the main bounding box and at least one of the multiple shadow parameters; creating a shadow brush by applying a shadow transformation matrix to the main brush, where the shadow transformation matrix maps the main object to a shadow defined by the multiple shadow parameters; inserting, into a main display list for the page, a set of instructions to: paint the shadow bounding box with the shadow brush; and paint the main bounding box with the main brush.

Abstract: A method for rendering an electronic document (ED). The method includes obtaining an intermediate format of the ED having multiple containers corresponding to multiple linked textboxes in the ED; obtaining a data structure including a root node associated with a string for distribution across the multiple linked textboxes and multiple segment nodes including multiple pointers to the multiple containers; executing a traversal of the multiple segment nodes; generating, during the traversal, multiple intermediate pages by applying a layout engine to the multiple containers referenced by the multiple pointers, where the string is distributed across the multiple intermediate pages; and generating a rendered page of the ED by substituting the container with an intermediate page corresponding to the container.
