Scanned images are bitmaps (See “Figure 6. Bitmapped Text Appearance”). The edges of curves on bitmapped images will not appear to be smooth or rounded but will be jagged, as shown in the sample illustrating the word “Writing” in Figure 6. Use the Marquee Zoom tool in Acrobat to define the area and magnify the edges of curved letters such as “c”, “s”, and “o”. Text that has undergone the OCR process using the ClearScan option will display edges that are smoother but still uneven or lumpy where there should be smooth curves, as shown in the illustration of the of the words “Quality” and “region” in Figure 7.
