Abstract
Abstract A graphic-transforming apparatus and method are provided for freely transforming an object graphic with easy operations. A curve or polygonal line to be transformed, that is, the object graphic, and a pattern consisting of a closed curve and functioning as a ruler are set up and a transformation is executed in which a part of the object graphic is replaced with a part or the whole of the pattern by specifying a transformation range, that is, by specifying a starting point, an ending point, and the direction of the route according to certain rules. The pattern consists of any line drawing such as a circle or polygon, which can be moved (and also rotated, enlarged, and contracted) and freely operated on the object graphic like moving a ruler on a drawing paper. The following rules are applied to the starting point, ending point, and route. The starting point must be an intersection between the object graphic and the pattern. The ending point must be a point on the pattern. The specified portion from the starting point of the pattern to the ending point through the route in the specified direction must be replaced with the specified portion from the starting point of the object graphic to its ending point or its extreme point.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
206 words
A method for transforming a graphic by a graphic transforming apparatus having input means, storage means, computation means, and display means, said method comprising the steps of: setting up a line drawing to be transformed as an object graphic for display on said display means, wherein said object graphic has an extreme point at an end of a line of the line drawing, setting up and acquiring any line drawing as a pattern for transformation for display on said display means, moving said pattern so that it intersects with said object graphic at at least one intersection, and also specifying an intersection between said object graphic and said pattern as a starting point, and also specifying a point on said pattern as an ending point, wherein said ending point is not an intersection between said object graphic and said pattern, and uniquely specifying the portion between the starting point on said object graphic and the extreme point on said object graphic as a specified portion by said computation means, and also uniquely specifying the portion between the starting point and the ending point on said pattern, and replacing said specified portion on said object graphic with the specified portion on said pattern by said computation means.
Claim 2
Independent Claim
206 words
A method for transforming a graphic by a graphic transforming apparatus having input means, storage means, computation means, and display means, said method comprising the steps of: setting up a line drawing to be transformed as an object graphic for display on said display means, wherein said object graphic has an extreme point at an end of a line of the line drawing, setting up and acquiring any line drawing as a pattern for transformation for display on said display means, moving said pattern so that it intersects with said object graphic at at least one intersection, and also specifying an intersection between said object graphic and said pattern as a starting point, and also specifying a point on said pattern as an ending point, wherein said ending point is not an intersection between said object graphic and said pattern, and uniquely specifying the portion between the starting point on said object graphic and the extreme point on said object graphic as a specified portion by said computation means, and also uniquely specifying the portion between the starting point and the ending point on said pattern, and replacing said specified portion on said object graphic with the specified portion on said pattern by said computation means.
Claim 3
Dependent Claim
24 words

Claim 7
Dependent Claim
50 words
A method for transforming a graphic according to claim 1, wherein, in the step of acquiring said pattern, one of a plurality of previously-prepared patterns is selected and, in the step of moving said pattern, said selected pattern is transformed into a state suitable for transformation of said object graphic.
Claim 8
Dependent Claim
172 words
