IPC: G06T3/60
Filed: 1990-09-28
Abstract: PURPOSE:To accurately minimize the width and length of a rectangular shape within a short time by providing this graphic processing system with a shape information rotating means for rotating shape information by a rotational angle obtained by a parameter acquiring means or a rotational angle calculated by an automatic rotational angle setting means and forming the rotated shape information. CONSTITUTION:When a shape size correcting system 1 is started, the parameter acquiring means 11 is driven at first, and only when the execution parameter obtained by the means 11 is automatic setting, the automatic rotational angle setting means 12 is driven. Finally, the shape information rotating means 13 is driven and then control is returned to the system 1. Since the system 1 automatically calculates and sets up the rotational angle minimizing the area of a rectangle in a shape obtained from the shape information without allowing the user to instruct the rotational angle, it is unnecessary for a user to execute the detailed calculation of the rotational angle minimizing the rectangular areas of the shape. Consequently, operation is executed within a short time and the width and length of the rectangular shape are accurately minimized.
