Abstract of the Disclosure This invention relates to an image describing apparatus for describing a coupling area for forming an image via a graphic command of polygonal shape or a circular arc which has means for extracting area data of boundary point row in the coupling area, means for approximating the boundary point row in a linear primitive or curve primitive of a circular arc, means for dividing the curve primitive so that other area does not exist in the area of the graphic command corresponding to the curve primitive if other area exists in the area of the graphic command corresponding to the approximated curve primitive , and means for coverting the approximate boundary into a graphic command of polygonal shape or circular arc and setting a preferential sequence to the command to form encoded data.
