A method for processing an electronic document (ED) to infer columns in the ED, where the ED comprises a plurality of characters. The method includes generating a mark-up version of the ED having text-layout attributes of the characters in the ED, where the characters are grouped into paragraphs based on the text-layout attributes, and each paragraph corresponds to a paragraph bounding box surrounding a corresponding paragraph, generating border pieces by initiating a pair of left scan and right scan from each paragraph bounding box to identify any adjacent paragraph bounding box, and generating, based at least on the border pieces, column borders for use in inferring the columns in the ED, where at least one column has a vertically aligned portion of the paragraphs.

A steganographic coding detector (and method) analyzes one or more pages of a file. For each page containing text strings, the detector counts a number of A0h and 20h characters for the text string. For each text string for which the number of A0h characters is greater than a first threshold, the detector sets a flag to a first state, The first threshold is computed based on the number of 20h characters in that text string. For each text string for which the number of 20h characters is less than the first threshold, the detector sets the flag to a second state. Responsive to the number of text strings that have a flag at the first state being greater than a second threshold, the detector marks the file as being steganographically encoded.

Tools and techniques are described to render oversize glyphs in a monospace grid. Glyph rendering algorithms collect changed cells, collect affected cells based on overlap, clear certain affected cells, and redraw only specified cells. By reducing the number of cells whose glyphs are redrawn in response a text edit, algorithms permit faster execution even when rendering is done by a script rather than precompiled code. Algorithmic advances also permit faster display frame rates, and help preserve battery power. Grids may be numbered, and traversed, in different ways. Oversize glyphs may include underscores, ligatures, mathematical symbols, emojis, kanji, accented characters in various natural languages, and wide or tall text characters which extend beyond the display space of a single cell. Glyph rendering may provide user interface updates in browsers, shells, terminal emulators, and other programs.

A device and method for providing recommended words for a character input by a user are provided. The method by which the device provides recommended words includes: receiving an input for inputting a character in a character input window; recommending at least one pseudo-morpheme including the input character by analyzing the input character; recommending at least one extended word including a selected pseudo-morpheme in response to receiving an input for selecting one of the at least one pseudo-morpheme; and displaying a selected extended word in response to receiving an input for selecting one of the at least one extended word.

According to various embodiments, there is provided a method for displaying a string of text, the method including: dividing the string of text into a plurality of substrings; and for each substring of the plurality of substrings: determining a complexity index of the substring; determining a display duration of the substring based on the determined complexity index; and displaying the substring for the determined display duration.

Asymmetrical formatting of word spaces according to the uncertainty between words includes an initial filtering process and subsequent text formatting process. An equivocation filter generates a mapping of keys and values (output) from a corpus or word sequence frequency data (input). Text formatting process for asymmetrically adjusts the width of spaces adjacent to keys using the values. The filtering process, which generates a mapping of keys and values can be performed once to analyze a corpus and once generated, the key-value mapping can be used multiple times by a subsequent text processing process.

First user specified criteria is received at graphical user interface (GUI) software. A first visualization is automatically displayed, via the GUI software, based on the first user specified criteria. The first visualization is defined by a rectangular area having a fixed width dimension and variable height dimension. The first visualization includes pixels that each represent one of the objects. A particular pixel is at a first position in the visualization. A second user specified criteria that includes grouping criteria is received at the GUI software. Groups of categorized objects are created by categorizing the objects based on the second user specified criteria. A second visualization that includes the pixels is automatically displayed via the GUI software by automatically reformatting the particular pixel from the first position to a second position based on the second user specified criteria.
