PURPOSE:To execute an affine transformation processing by determining an end point at every prescribed length along an axis of coordinate from a prescribed position of a coordinate system which is brought to an affine transformation, setting a line passing through the end point and being parallel to the axis, setting each coordinate to be used for the affine transformation, and determining a start coordinate. CONSTITUTION:The titled device is provided with a pitch process for determining an end point at every prescribed length along the Y axis or the X axis of coordinate systems (x), (y) from a prescribed position of the coordinate systems (x), (y) which is brought to an affine transformation, and a line setting process for setting a line passing through the end point determined by the pitch process, and also, being parallel to the (x) axis or the (y) axis opposed to the Y axis or the X axis of the coordinate systems (x), (y) which is brought to an affine transformation. Also, this device is provided with a coordinate setting process for setting each coordinate of the coordinate systems X, Y to be used for the affine transformation along each line which is set by the line setting process, and a start coordinate determining process for determining a start coordinate to start the affine transformation, at every line, with regard to each coordinate which is set by the coordinate setting process. In such a way, by repeating a simple processing, the affine transformation processing can be executed at a high speed. |
