Claim:
1. A method implemented by an information handling system that includes a memory and a processor, the method comprising: identifying a plurality of sections from a sequence of characters included in a Portable Document Format (PDF) source file, wherein each section includes a unique set of coordinate positions; building a plurality of directional links between the plurality of sections based on a relative position of each sections' coordinate positions in relation to other sections' coordinate positions along an axis; and repeatedly merging two or more sections to form increasingly larger sections, wherein the merged two or more sections are selected based on the directional links built between the two or more sections, wherein the repeatedly merging further comprises building one or more new directional links between the increasingly larger sections and one or more remaining sections selected from the plurality of sections, and wherein the repeatedly merging continues until the plurality of sections are exhausted and consolidated into a final larger section, wherein the final larger section is arranged in an intended reading order.
