Abstract

PURPOSE:To reduce a work volume to reduce the burden of an operator by transforming a graphic with a preliminarily generated complicated line as the graphic transformation guide line to simplify the transforming operation even in the case of transformation of the graphic to a complicated form. CONSTITUTION:When the transformation processing program stored in a program memory 5a is executed, a graphic transforming operation picture A is displayed on a display device 3, and the operator operates a mouse 2 to move a mouse cursor B and designates a rectangular area C surrounding the graphic of a transformation object (flower). A CPU 6 retrieves the graphic included in the area C in a graphic memory 5b based on information of the area C to decide the graphic as the transformation object. The center line in the longitudinal direction of the area C is calculated and is stored in a memory 5 as a reference line D for graphic transformation. A curve indicating the form after transformation is designated by the mouse cursor B to determine a guide line E, and data of the line E is stored in a memory 5d. The CPU reads out data of the graphic of the transformation object from the memory 5b and transforms the graphic based on graphic data where the reference line D is matched for the form of the line E.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a graphic processing device for a graphic whose shape is described by contour information, vector information, etc., and particularly relates to graphic deformation processing.

[Prior Art] Conventionally, when transforming a figure in a graphic processing device, the figure to be transformed is designated as being included or divided into a rectangular area, and the rectangular area is enlarged, reduced, or rotated. By performing deformation operations such as , tilting, trapezoidal deformation, etc., figures included or configured in the same area are also deformed, and figure deformation processing is performed so that the figure is transformed into a desired figure shape.

In addition, the shape to be transformed can be specified by specifying a point near the contour of the shape, and the reference point or reference line specified by the operator or automatically determined by the shape processing device can be By moving the specified point near the outline above, you can enlarge/enlarge the specified figure.
Transformations such as reduction, rotation, tilt, and object transformation were performed.

[Problems to be Solved by the Invention] However, the above method for transforming a figure does not allow complicated transformations, such as transforming a figure into an S-shape or spiral shape, or free-form transformations, such as transforming a figure to fit a freehand line. It was difficult to perform transformations. In other words, when performing such a transformation, the figure is divided into several parts, each divided area is transformed by enlarging or contracting, etc., and by superimposing these partial transformations, the shape of the figure as a whole is transformed. I was trying to complete the transformation. However, it has been difficult to continuously and neatly deform the deformed divided portions and even the figures.

In addition, with the above transformation method, even when performing the same transformation operation on multiple shapes, it is necessary to respecify the transformation contents for each shape, which increases the amount of operation for the operator. This increases the possibility of making operational mistakes, making it difficult to accurately perform deformation operations on multiple figures.

The present invention has been made to solve the above-mentioned problems, and when deforming a figure, a line that serves as a guide for the figure deformation is specified in advance, and a line corresponding to this guide line is set. By transforming a shape, you can easily perform the transformation operation even when transforming a shape into a complex shape, and even when performing the same transformation process on multiple shapes. It is an object of the present invention to provide a graphic processing device that reduces the amount of operation work and reduces the operation burden on an operator.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a storage means for storing contour information or vector information indicating the shape of a figure, and a display means for displaying the figure information stored in this storage means. In a graphic processing device equipped with a display device that displays a shape to be transformed, and a designation means for determining a shape to be transformed from a shape displayed on the display device, a standard that serves as a reference when transforming a shape to be transformed specified by the designation device. a determining means for determining a line; a guideline specifying means for specifying a line that will serve as a guide for transforming the figure to be transformed into a desired figure; The apparatus includes a deforming means for deforming a figure to be deformed by converting information, and the deformed figure is displayed on a display means.

[Operation] According to the above configuration, when a figure is transformed, the reference line of the figure designated as a transformation target and the line that serves as a guide for transforming this figure into a desired figure are arbitrarily specified in advance, When the transformation is executed, the figure is automatically transformed so that the reference line is aligned with the guide line, and the figure to be transformed is transformed into a desired figure shape.

[Embodiment] Hereinafter, a configuration according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 and FIG. 2 are a block diagram and a functional configuration diagram, respectively, showing the main configuration of a graphic processing device of the present invention.

This graphic processing device includes a keyboard device 1 for inputting characters and specifying operations, a mouse device 2 for specifying figures, rectangular areas, and operations, and a display device for displaying figures, operation guidance, processing result figures, etc. 3, a printer 4 that prints the deformed figure, a storage device 5 that stores contour information or vector information indicating the shape of the figure, and a CPU 6 to which these devices are connected and controls the entire device. There is.

The storage device 5 includes a product memory 5a that controls the entire device and stores a transformation processing program for executing the present invention, and a graphic memory 5b that stores graphic data.
and a reference line memory 5C that stores data on reference lines of figures.
and a line data memory 5d that stores line data that serves as a guide for graphic deformation.

Further, the above-mentioned graphic processing device will be explained from the functional configuration point of view with reference to FIG. 2. First designation means 10 for designating a shape to be transformed, determination means 11 for determining a reference line of the shape to be transformed, and this standard. A second specifying means 12 (guideline setting means) for indicating the shape of the line after deformation and specifying a line to serve as a guide for figure deformation, and aligning the reference line with an arbitrary line specified by the second specifying means. It is composed of a deforming means 13 for deforming a figure as shown in FIG.

In the above configuration, a graphic deformation process in which a line serving as a guide for graphic deformation is specified in advance and a graphic deformation operation is performed will be explained based on FIGS. 3 and 4. Third
4 and 4 are explanatory diagrams showing the process of a figure modification operation displayed on the display device 3, respectively, and FIG. 4 is a flowchart showing the operating procedure of the same modification operation.

When the deformation processing blockrum stored in the program memory 5a is executed, the display device 3
A figure transformation operation screen A is displayed, and the operator operates the mouse 2 to move the mouse cursor B and designate a rectangular area C so as to surround the figure (flower) to be transformed. Based on the information on this rectangular area C, the CPU 6 searches the graphic memory 5b for a graphic included in the rectangular area C, and determines this graphic to be a target graphic for transformation. Next, as shown in FIG. 3(b), the vertical center line of the rectangular area C is calculated, and this center line is determined as a reference line that will be used as a reference when deforming the figure.
This reference line is stored in the reference line memory 5C. moreover,
As shown in FIG. 3(c), a curve indicating the shape of the figure after deformation is specified with the mouse cursor B, a guide ME is determined as a guide for the figure deformation, and the data of this guide line E is converted into line data. It is stored in the memory 5d.

After obtaining the reference line and the guide line E, when further executing the transformation process, the CPU 6 reads the figure data of the figure to be transformed from the figure memory 5b, and adjusts the reference line to the shape of the guide IIE. Then, based on the result of the calculation, the figure to be transformed is transformed as shown in FIG. 3(d).

In the above embodiment, the vertical center line of the rectangular area C was selected as the reference line, but this is more useful because the rectangular area C surrounding the figure is used as a means of specifying the figure to be transformed. The vertical center line that is considered to be frequently used was selected, but the horizontal center line of the rectangular area C or one side of the rectangle may also be used. Further, the guide line E may be created by the operator drawing it by operating the mouse 2 on the figure transformation operation screen, or may be formed by calling the stroke font data of the character on the same screen. .

Furthermore, the operation of the above-mentioned figure deformation operation will be explained based on the flowchart of FIG. 4 showing the operation procedure.

A mouse or the like is operated on the figure transformation operation screen to designate a rectangular area surrounding the figure to be transformed (step Sl). The figure surrounded by this rectangular area is the figure to be transformed (S2
). Thereafter, the center line of the rectangular area is determined as a reference line (S3), and a guide line that will serve as a guide for deformation is specified by operating the mouse (S4). When the deformation process is executed at the stage where these reference lines and guide lines are obtained, the figure is deformed so that the reference lines match the guide lines.

In this way, you can draw a guide line that serves as a guide for shape transformation using a mouse, etc. separately from the shape to be transformed, and then transform the shape according to this guide line. By drawing complex shapes such as curves and spiral curves, complex deformations of figures can be made relatively easily.

Next, the process of deforming a graphic by calculating the graphic data will be described in detail based on the flowchart of FIG. 5, which explains the calculation of the deformation process, and FIG. 6, which shows the operating procedure of the deformation process.

As shown in FIG. 5, the figure deformation process is performed by first calculating the total length Lb of the reference line of the rectangular area surrounding the figure to be deformed (step S6 in FIG. 6; the same applies hereinafter), and then calculating the guide line. The total length Lg of line E is calculated (S7). Next, calculations for deformation processing are performed for each constituent point of the figure to be transformed.For example, for the constituent points Pi of the figure to be transformed, the input direction y Distances Wi and Hi in each direction are calculated (S8). Next, trace the guide line from the starting point (Xg, Yg) of guide line E,
A point Gi whose distance on the guide line E is (Lg/Lb) Hi is calculated (S9). Then, a perpendicular line to the guide line E at the point Gi is determined, and on the perpendicular line, the distance from the guide line is Wi A point Qi is calculated (310). This point Qi is moved toward the reference line by (Xg-Xb, Yg-Yb). This moved point becomes the constituent point Pi' of the figure after transformation, which corresponds to the constituent point Pi of the figure before transformation (
311). After that, it is determined whether the calculation of the transformation process has been completed for all the constituent points (Sl 2>, if it has been completed, the calculation is finished; if it has not been completed, the process returns to step 8 and all Below, until you finish the configuration point,
Repeat similar steps.

By creating a figure from the contour information indicated by the above-mentioned new constituent points, a figure obtained by deforming the figure to be deformed along the shape of the guide line E can be obtained.

[Effects of the Invention] As described above, according to the present invention, in the graphic processing device,
You can transform a shape by using a complicated line such as a spiral curve that has been created in advance as a guide line for shape transformation, so even when you want to freely transform a shape in a complicated way, you can use a guide that shows the desired shape. It is only necessary to draw lines, which simplifies the manipulation of figure transformation and reduces the operational burden on the operator. In addition, the guide line using − degrees can be used many times as a guide line for shape deformation, so
The same transformation of a plurality of graphics can be performed accurately and easily, and the operability of the graphics processing device can be improved.
