Modifying print information based on feature detection
 An information processing method includes inputting bit information, temporarily storing at least part of the input bit information, and detecting whether the stored bit information coincides with one predetermined feature of plural such predetermined features. Print information for an object pixel which corresponds to a stored bit is modified in a case where coincidence is detected. Modification may include, for example, contour retention in a case where a rectangular portion is detected, line width discrimination, or white line discrimination. In addition, second feature detection can determine that a right-angled portion is not involved, in which case print information is modified only if coincidence is detected with plural predetermined features and a right-angled portion is not detected.
