1. A system for generating an image-based reflowable file, comprising: a data store for storing image-based reflowable files; and a computing device in communication with the data store that is operative to: retrieve an image of content having one or more reflow objects, wherein the image of content corresponds to an image of printed textual content and wherein the reflow objects corresponds to the textual content; identify a reflow object baseline for each of reflow objects; identify polygonal-shaped bounding regions for the reflow objects; determine the size of each bounding region; determine the position of each bounding region relative to the image and relative to its corresponding reflow object baseline; generate the image-based reflowable file comprising the reflow object baselines and the size and the position of each of the bounding regions; store the generated image-based reflowable file in the data store; and render the image-based reflowable file on a computer display.
