Color coding of layout structure elements in a flow format document

摘要

A color coding engine and a comparison engine are provided. A color coding engine may be utilized to detect logical layout object attributes in a flow format document and apply a unique color to textual elements associated with each logical layout object attribute. The resulting color coded document may be saved as a target flow format document. The target flow format document may be converted to a fixed format document and then converted by a conversion engine to a flow format document. The resulting converted flow format document may be saved as an output flow format document. A comparison engine may be utilized to compare the output flow format document and the target flow format document to determine if layout information has been properly preserved in the document conversion process.
