A method of and system for converting an original representation of a page element expressed in bitmap form into a page definition language representation of the page element develops an element approximation expressed in the page definition language, converts the element approximation into an approximation bitmap and compares the approximation bitmap to the original representation expressed in bitmap form to obtain an error indication. The error indication is checked to determine whether it meets a certain criterion and, if so, the element approximation is used as the page definition language representation. Otherwise, one or more further element approximations are developed until an element approximation is obtained that results in an error indication which meets the certain criterion.

A method of reproducing a page element by converting a bitmap representation of the page element at a first resolution into a page definition language representation of the page element, the method comprising the steps of: (a.) establishing a first set of recognition parameters; (b.) using the established set of recognition parameters to convert the bitmap representation into an element approximation expressed in the page definition language, wherein the element approximation includes an indication of an approximation of the identity of the page element and an indication of an approximation of a font in which the bitmap representation is expressed, and wherein the page element is reproducible from the element approximation at a second resolution different than the first resolution; (c.) converting the element approximation into an approximation bitmap; (d.) comparing the approximation bitmap to the bitmap representation to obtain an error indication; (e.) determining whether the error indication meets a certain criterion; and (f.) reproducing the page element using the element approximation as the page definition language representation if the error indication meets the certain criterion; or (g.) repeating steps (b.) through (f.) at least once if the error indication fails to meet the certain criterion using at least one different established set of recognition parameters until an element approximation is obtained that results in an error indication which meets the certain criterion.
