Abstract:
1. An image-drawing device having image-drawing heads which are moved relatively in a predetermined scanning direction along an image-drawing surface, and carrying-out image-drawing on the basis of image-drawing data, the device comprising: a plurality of image-drawing elements structured so as to be lined-up two-dimensionally within a plane substantially parallel to the image-drawing surface of the image-drawing heads, and at the image-drawing surface, the plurality of image-drawing elements on the whole structure image-drawing element groups which generate two-dimensional image-drawing pixel groups which are inclined at a predetermined angle of inclination with respect to the scanning direction; an image-drawing magnification setting unit setting an image-drawing magnification such that the image-drawing magnification has an effective value after a decimal point; and a data allocating unit allocating the image-drawing data at predetermined timings to the respective image-drawing elements, so that a resolution becomes a resolution corresponding to the value after the decimal point of the image-drawing magnification, wherein the image-drawing magnification is expressed by a value equal to a pixel pitch in the scanning direction being divided by an image-drawing pitch of the image-drawing elements.
