<p>PURPOSE:To designate exactly and easily a length and an angle, and to draw a picture with high operability by displaying a scale based on a designated reference point as a reference. CONSTITUTION:A vector (reference line) which becomes a reference is brought to picture drawing to a position which is designated by a mouse cursor of a mouse 2, also a center point (reference point) which is designated by the mouse cursor of the mouse 2 is inputted, and a linear scale and an angle scale are displayed, based on its reference point as a reference. In this state, the picture drawing processing of a rotation, etc. of a line drawing and a display picture is executed in accordance with a designation by the mouse 2, etc., and thereafter, the scales are erased. In this way, the scale based on the designated reference point on a picture as a reference is displayed, therefore, the picture drawing of a length and an angle can be executed exactly. Also, the generation of a histogram which has counted a picture element having the value of '1' by projecting a binary image in a prescribed direction, and the rotation of an image can be executed exactly, as well.</p> |
