A text line bounding system for non-mechanically adjusting for skewed text in scanned text. The data from scanned page texts are divided into vertical swaths and all pixels at respective vertical levels within each swath are set black if any one pixel within the swath at the level is black. Intersections and terminations are found and the datum for each line is established after removing extraneous data. The skew angle of the text is then established, following which the text lines are statistically bounded. The actual text data is then rotated according to the orientation established for conventional processing.
