Systems and methods are provided for rendering an image-based reflowable file. The image-based reflowable file may be configured to adapt itself to be rendered on various sized displays, such as by permitting lines of reflow objects to 'reflow' according to the given size of a display. An image-based reflowable file may include one or more reflow objects, where each reflow object forms a sub-image and is defined in a bounding region. Rendering an image-based reflowable file may include determining a horizontal render position and a vertical render position for each bounding region.

Generating image-based reflowable files for rendering on various sized displays

A computer system and method for processing a digital image into reflow content is presented. A computer system includes a processor and a memory. The computer system is configured to process a digital image by first obtaining the digital image, wherein the digital image includes at least some content suitable for conversion into reflow content. The computer system identifies any headers or footers that exist within the digital image. The computer system then processes the digital image into reflow content, excluding any content within an identified header or footer. Headers and/or footers are identified according to one or more aspects indicative of a header/footer, such as separating white space, a separator line, sequences indicative of page numbering, and the like.

Processing digital images including headers and footers into reflow content

Processing content in a digital image into reflow content is presented. In operation, a computer system is configured to obtain a digital image from a source. The digital image comprises content including both reflow content and non-reflow content. The computer system identifies non-reflow blocks of content within the digital image and processes the digital image into reflow content, excluding the identified non-reflow blocks of content. The reflow content is copied to a digital content file or stream. The identified non-reflow blocks of content are also copied to the digital content file/stream. Information regarding the non-reflow blocks of content, such as its location in the digital image and a confidence rating, are included with the non-reflow block copied to the digital content file/stream.

Generating reflow files from digital images for rendering on various sized displays

A computer-implemented method is provided for creating an image-based reflowable file. The image-based reflowable file is configured to automatically adapt itself to be rendered on various sized displays and windows, by permitting the lines of reflow objects to 'reflow' according to the given size of a display or window. The method includes receiving. First, an image of content having reflow objects and identifying bounding regions to enclose a reflow object contained in the image. A reflow object baseline for each of the reflow objects is then identified and the position of each of the bounding regions containing the reflow objects is determined, relative to the image and also relative to the corresponding reflow object baseline. The size of each of the bounding regions is then determined, for example in terms of width and height, and stored.

A computer system and method for efficiently processing a digital image into reflow content is presented. The method comprises each of the following as executed on a computer. A digital image is obtained for processing. The digital image includes at least some content suitable for conversion into reflow content. The digital image is processed into a digital content file. The digital content file includes both reflow content and non-reflow blocks of content. For each non-reflow block of content in the digital content file, the following are performed. A confidence rating is determined for the non-reflow block of content. If the confidence rating for the non-reflow block of content falls below a predetermined threshold, an evaluation of the non-reflow block is triggered.

Efficient processing of non-reflow content in a digital image

A computer-implemented method is provided for converting a scanned-in electronic image into a token-based file. The method includes generally five steps. First, various tokens (i.e., graphical units) are identified in the electronic image. Second, the identified tokens having similar shapes are classified together to form a token group, to thereby form multiple token groups, each including one or more tokens having similar shapes. Third, in each token group, a representative token is found, which morphologically represents the shapes of tokens included in the group. Fourth, each representative token is converted into a vectorized token, which is a mathematical representation of the shape of the representative token. Fifth, each of the vectorized tokens is associated with the positions of the tokens in the electronic image represented by the vectorized token. Thus, upon rendering, the vectorized token is displayed to thereby create a page image consisting only of clean images of vectorized tokens.

Converting digital images containing text to token-based files for rendering

A computer system and method for efficiently processing a digital image into reflow content is presented. The method comprises each of the following as executed on a computer. A digital image is obtained for processing. The digital image includes at least some content suitable for conversion into reflow content. The digital image is processed into a digital content file. The digital content file includes both reflow content and non-reflow blocks of content. For each non-reflow block of content in the digital content file, the following are performed. A determination is made as to whether the non-reflow block of content should be manually evaluated for editing. A manual evaluation is automatically triggered for editing if it is determined that the non-reflow block of content should be manually evaluated for editing.
