1. An image processor comprising:
a first converter which extracts a line image region in input bit map image data and converts the line image to vector data;
a second converter which detects a side where a target pixel in pixels exists relative to the line image region defined by the vector data and converts a value of the bit map data of the target pixel according to a value of the input bit map data around the line image region of the detected side; and
a composer which composes the vector data of the line image obtained by said first converter and the bit map data converted by said second converter.
