Abstract
The present invention provides a picture-processing apparatus and method for finding a point A (x , y ) on a projection drawing showing a first surface as a point corresponding to a point a (−1/2, y ) on the left side of a square shape forming an expansion drawing of the first surface and a point B (x ′, y ′) on the projection drawing as a point corresponding to a point b (1/2, y ) on the right side of a square shape forming an expansion drawing of a second surface adjacent to the first surface on the basis of a predetermined transformation relation. On the expansion drawings, the point a coincides with the point b. The transformation relation is corrected by finding average coordinates ((x +x ′)/2, (y +y ′)/2) as the coordinates of a new point C located on the projection drawing and designated as a point corresponding to the point a (−1/2, y ), and using a pair of the point C and the point a (−1/2, y ) as a base for a new transformation relation. As a result, a natural expansion drawing found by using the new transformation relation can be obtained, allowing editing work to be done with ease.
