Abstract

PROBLEM TO BE SOLVED: To easily apply modification information to a character set in a sentence without overlapping the character set. SOLUTION: When a character string contains a character set, a work variable pos(y) at the lower end of a character set is initialized to '0' (S21), the underline- starting character of the character set is acquired (S22), the y-coordinate of the lower end of the character set under processing is set to the work variable pos2 at the lower end of the character set (S23) and, if the work variable pos(y) of present underline y is smaller than the work variable at the lower end of character set pos2, the operation is proceeded to the step S26 and, if the answer of the step S24 is (yes), the work variable pos(y) of the underline y is set to the work variable pos2 at the lower end of the character set and the operation is proceeded to the step S26. Subsequently, the judgment of whether or not the character under processing is an end character of the character set, is performed and if the character is the end character of the character set and the end character of underline, the work variable pos(y) of the underline y is set to an underline starting y coordinate position start(y) and an underline ending y coordinate position end(y) to complete the operation.

In a document processing device including an output unit that outputs document information, a modification direction determination unit that determines a modification direction of the modification information to be attached to the character string, and the character string in a direction orthogonal to the modification direction. A coordinate position detecting means for detecting the coordinate position of the outermost end of the character string, and the arrangement position setting means arranges the arrangement of the decoration information for the character string on the basis of the coordinate position detected by the coordinate position detecting means. It is characterized in that it has a modification information position determining means for determining.

Further, in the method for arranging decoration information on a character string according to the present invention, after determining a modification direction of the modification information to be attached to the character string, the modification direction in the character string in a direction orthogonal to the modification direction is determined. The coordinate position of the extreme end is detected, the arrangement of the modification information with respect to the character string is determined based on the coordinate position, and then the arrangement of the modification information is determined, and then the modification information is attached to the modification direction. It is characterized in that it has a modification information position determining means for outputting the document data in which the modification information is added to the character string.

Further, in the above document processing apparatus and method for arranging decoration information for a character string, at least one set character is included in the character string,
Further, the modification information is characterized by being underlined information, overlined information, or enclosing ruled information. Here, in the present specification, the underline information includes not only what is attached to the lower side of the character string with respect to the horizontally written character string, but also what is attached to the right side of the character string with respect to the vertically written character string.
