Description
Technical Field
The present invention relates to the field of graphics modification technologies, and in particular, to a method and an apparatus for adjusting a vertex type of a graphic, and an electronic device.
Background
In teletext office software, a user can draw a graphic of various shapes, e.g., circles, rectangles, triangles, etc., consisting of line segments or arcs. Wherein each graph comprises a plurality of vertexes, and two control points are arranged near each vertex, as shown in fig. 1, and points a, b, c and d are four vertexes of the graph circle. In general, vertex types in an image may be classified into smooth vertices, straight vertices, and corner vertices. The user may alter the shape of the graph by adjusting the type of vertices in the graph. For example, the user may adjust the circular figure to a parallelogram by adjusting the vertex types of the four vertices of the circle from smooth vertices to corner vertices.
Currently, when the vertex type of a graph is converted from a smooth vertex (a straight vertex) to a corner vertex, a user may first convert the vertex type of a vertex in the graph recorded in a configuration file corresponding to software from a smooth vertex (a straight vertex) to a corner vertex. Then, the user manually adjusts the two control points of the vertex until the line segment (or arc) between the vertex of the adjusted vertex type and its adjacent vertex is made a straight line, so that the vertex type of the graph can be converted from a smooth vertex (straight vertex) to a corner vertex.
Obviously, when the vertex type of the graph is manually adjusted from a smooth vertex (a straight vertex) to a corner vertex by the current user, the line segment (or the circular arc) between the vertex of the adjusted vertex type and the adjacent vertex cannot be accurately and efficiently adjusted to be a straight line.

First, a method for adjusting a vertex type of a graph according to an embodiment of the present invention is described below.
The application provides a method for adjusting the graph vertex type, which can be applied to terminal equipment. The terminal equipment can be equipment provided with image-text office software such as Microsoft or wps office. For example, the device may be a mobile phone or a tablet PC, or may be a Personal Computer (PC), a television, or the like.
Referring to fig. 2, fig. 2 is a schematic flowchart of a method for adjusting a vertex type of a graph according to an embodiment of the present invention, where the method includes the following steps:

In practical application, in the graphic office software, a user can draw various shapes of graphs consisting of line segments or circular arcs. Meanwhile, the terminal device installed with the image-text office software stores object configuration files corresponding to various images drawn by the user through the office software. In the embodiment of the invention, the vertex to be subjected to vertex type adjustment in the target graph is called a target vertex. The object configuration file can contain type identification of a target vertex and coordinates of at least two control points corresponding to the target vertex; in the embodiment of the invention, the number of the control points corresponding to the target vertex is two. The type adjustment instructions are for adjusting the vertex type of the target vertex to a vertex type corresponding to the corner vertex identification.
In implementation, the graphic office software is provided with an interface for human-computer interaction, and when a user needs to adjust the vertex type of a target vertex on a target graph on the interface, the user can click the target vertex of the target graph on the interface. And the terminal equipment correspondingly generates a type adjusting instruction aiming at the target vertex of the target graph. When the terminal device detects a generated type adjustment instruction for a target vertex of a target graph, the terminal device obtains an object configuration file corresponding to the target graph.
S202, the vertex type of the target vertex in the object configuration file is modified into the vertex type corresponding to the corner vertex identification.
In implementation, after acquiring the object configuration file corresponding to the target graph, the terminal device may modify the current vertex type of the target vertex recorded in the object configuration file to the vertex type corresponding to the corner vertex identifier.

For each control point of the target vertex, the terminal device may determine, according to a preset coordinate calculation formula in the preset control point coordinate determination policy and the first coordinate of the control point before the vertex type of the target vertex is adjusted, the second coordinate of the control point after the vertex type of the target vertex is adjusted to the corner vertex type.

wherein a is a first relative angle between the target vertex and a first adjacent vertex of the target vertex, x and y are coordinates of the target vertex, and x 'and y' are coordinates of the first adjacent vertex adjacent to the target vertex.
And S303, inputting the first distance and the first relative angle into a control point abscissa calculation formula in a determination strategy to obtain a second abscissa of the control point corresponding to the target vertex.

In an implementation, after the terminal device determines the second coordinates of each control point through step S203 described above, the terminal device may use the determined second coordinates as the coordinates of each control point corresponding to the target vertex when the vertex type of the target vertex is the corner vertex type. And the coordinates of each control point of the target vertex in the object configuration file corresponding to the target vertex are adjusted, so that the coordinates of each control point corresponding to the target vertex in the object configuration file corresponding to the target vertex are modified, and the vertex type of the vertex can be accurately adjusted from a smooth vertex or a straight vertex to a corner vertex.
