Abstract: An image-based document may include text that is presented in a multicolumn format that is not structured or associated with metadata of the document. A zoom manager may analyze the image-based document, identify a presence and location of a column of text, and then enable automatic zooming-in on the column of text to fill a display space without further interaction by a user. In various aspects, the zoom manager may order the columns to enable the user to continuously scroll from column to column while navigating the document in a column-viewing (zoomed-in) mode. The zoom manager may also selectively maintain or remove information or objects from the columns while in the column-viewing mode, such as images, headers, footers, page numbers, or other types of information or objects.
