Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a method and a device for adjusting a graph, which are respectively described in detail below.
First, an execution body of the graphic adjustment scheme provided by the embodiment of the present invention is explained.
The execution subject may be a software client. For example, the software client may perform file processing such as WPS, Word, PDF, or may perform graphics processing.
In addition, the execution main body may also be an electronic device running the software client. Such as desktop computers, notebook computers, tablet computers, smart phones, and the like.
The following describes a method for adjusting a pattern according to an embodiment of the present invention with reference to a specific embodiment.
Referring to fig. 1, fig. 1 is a schematic flow chart of a graph adjustment method according to an embodiment of the present invention, where the method includes the following steps
In one embodiment of the present invention, the pattern to be adjusted may be a regular convex polygon, a regular star, or a circle. If the figure to be adjusted is a regular convex polygon or a regular star shape, the width and height of the figure to be adjusted may be the width and height of a circumscribed rectangle thereof. If the figure to be adjusted is a circle, the width and height of the figure to be adjusted may be the diameter of the figure to be adjusted.
Specifically, the regular convex polygon is a polygon having the following characteristics:
after any one side of the polygon is extended, the whole polygon is positioned at the same side of the extension line of the side; the vertex angles of the polygon are equal, and the side lengths of the polygon are equal. For example, the regular convex polygon may be: regular pentagons, regular hexagons, regular octagons, etc.
The regular star is a star with equal vertex angles and equal side lengths, such as a regular pentagram, a regular heptagram and the like.
In an implementation manner of the present invention, the width of the image to be adjusted may be obtained by obtaining the width of the image to be adjusted input by the user. For example, the electronic device may display an interface generation dialog box, and the user inputs the width of the graphic to be adjusted in the dialog box, so that the electronic device obtains the width input by the user.
In another implementation manner of the present invention, if the graph to be adjusted is a regular convex polygon or a regular star, the vertex coordinates of the graph to be adjusted may be identified, and the width of the graph to be adjusted may be calculated according to the coordinates.
In yet another implementation of the present invention, the width of the circumscribed rectangle of the graph to be adjusted is identified, and the width can be regarded as the width of the graph to be adjusted.
And 102, acquiring the number of edges of the graph to be adjusted as the representation information of the graph to be adjusted under the condition that the graph to be adjusted is a regular convex polygon.
In an implementation manner of the present invention, the number of edges may be obtained by obtaining the number of edges of the graph to be adjusted, which is input by the user. For example, the electronic device may display an interface generation dialog box first, and the user inputs the number of edges of the graph to be adjusted in the dialog box, so that the electronic device obtains the number of edges input by the user.
The other implementation manner of the invention can be to identify the number of vertex angles of the graph to be adjusted, and the number of sides of the regular convex polygon is the same as the number of vertex angles.
And 103, acquiring the vertex angle number of the graph to be adjusted as the representation information of the graph to be adjusted under the condition that the graph to be adjusted is in a positive star shape.
The method for realizing the vertex angle number adjustment comprises the step of obtaining the vertex angle number of the graph to be adjusted input by a user. For example, the electronic device may display an interface to generate a dialog box, and the user inputs the vertex angle number of the graph to be adjusted in the dialog box, so that the electronic device obtains the vertex angle number input by the user.
Another implementation of the present invention may be to directly identify the number of corners of the pattern to be adjusted.
And 104, acquiring the height of the graph to be adjusted, and calculating the radius of the circumscribed circle of the graph to be adjusted according to the height of the graph to be adjusted and the representation information.
In an embodiment of the present invention, the radius r of the circumscribed circle of the graph to be adjusted may be calculated according to the following expression:
wherein h represents the acquired height, n represents the representation information of the graph to be adjusted, and a, b and c represent preset parameters.
Specifically, the value of a may be 2, the value of b may be 3, and the value of c may be 2. In this case, if the number of the sides of the graph to be adjusted is 3 and the height is 20 pixel points, the radius r of the circumscribed circle of the regular triangle with the height of 20 pixel points can be calculated according to the following formula:
the calculation shows that the radius of the circumscribed circle of the regular triangle with the height of 20 pixel points is 13 pixel points.
In addition to the above, the values of a, b, and c may be other values, for example, a may be 1, 1.5, 2.5, 3, etc., b may be 2.5, 3.5, 4, etc., and c may be 1, 1.5, 2.5, 3, etc. The embodiments of the present invention are described above as examples, and the schemes provided by the embodiments of the present invention are not limited.
And 105, adjusting the graph to be adjusted according to the width of the pre-selected reference graph, the radius of the circumscribed circle of the reference graph, the first position point, the width of the graph to be adjusted and the radius of the circumscribed circle of the adjusted graph, so that the graph to be adjusted is aligned with the center point of the reference graph.
Wherein, the first position point is: points representing the reference picture positions.
Specifically, when centering images, at least two figures are centered, and it is generally known which figures are to be centered before centering. Based on this, the reference pattern may be determined by a user manually selecting a pattern to be centered, or a pattern to be centered may be selected by a random selection, and the selected image may be used as the reference pattern.
Specifically, the abscissa x2 and the ordinate y2 of the target point may be calculated according to the following expression, and the to-be-adjusted graph may be adjusted by adjusting the second position point to the target point:
y2＝y1+r2-r1
wherein the second location points are: points for indicating the position of the graph to be adjusted, w1 indicates the width of the reference graph, w2 indicates the width of the graph to be adjusted, r1 indicates the radius of the circumscribed circle of the reference graph, r2 indicates the radius of the circumscribed circle of the graph to be adjusted, and x1 and y1 respectively indicate the horizontal and vertical coordinates of the first position point.
Specifically, the first position point and the second position point are points representing positions of the reference pattern and the pattern to be adjusted, respectively. Referring to fig. 2, the first location point may be a center point of the reference pattern, or may be any vertex of a circumscribed rectangle of the reference pattern. Referring to fig. 3, the second location point may be a center point of the graph to be adjusted, or may be any vertex of a circumscribed rectangle of the graph to be adjusted.
In an embodiment of the invention, the first location point is an intersection of two adjacent edges in a circumscribed rectangle of the reference pattern.
Taking a circle as an example of the reference graph, assuming that a regular triangle with a height of 20 pixels is taken as the graph to be adjusted, a vertex where a left vertical edge and an upper horizontal edge of a circumscribed rectangle of the reference graph intersect is taken as a first position point, and a vertex where a left vertical edge and an upper horizontal edge of a circumscribed rectangle of the graph to be adjusted intersect is taken as a second position point. Wherein the reference pattern has a width of 20 pixel points, a radius of 10 pixel points, and a first position point coordinate of (10, 10); the width of the graph to be adjusted is 23 pixel points, and the radius is 13 pixel points, then the coordinates of the target points can be calculated by the following formula:
y2＝10+13-10＝13
the coordinates of the target point are (8, 13). And adjusting the graph to be adjusted to be aligned with the center point of the reference graph by moving the graph to be adjusted to adjust the second position point to the coordinates of the target point.
Specifically, referring to fig. 4, since the first position point may represent a position of the reference pattern, and the second position point may represent a position of the pattern to be adjusted, the second position point is adjusted to the calculated position of the target point, so that the center point of the pattern to be adjusted approaches the center point of the reference pattern.
Therefore, when the scheme provided by the embodiment of the invention is applied to adjust the graph, the width of the graph to be adjusted is obtained; under the condition that the graph to be adjusted is a regular convex polygon, acquiring the number of edges of the graph to be adjusted as representation information of the graph to be adjusted; under the condition that the graph to be adjusted is in a positive star shape, acquiring the number of vertex angles of the graph to be adjusted as representation information; the method comprises the steps of obtaining the height of a graph to be adjusted, calculating the radius of a circumscribed circle of the graph to be adjusted according to the height of the graph to be adjusted and characterization information, and adjusting the graph to be adjusted according to the width of a pre-selected reference graph, the radius of the circumscribed circle of the reference graph, a first position point, the width of the graph to be adjusted and the radius of the circumscribed circle of the graph to be adjusted, so that the graph to be adjusted is aligned with the center point of the reference graph. Compared with the prior art, when the scheme provided by the embodiment of the invention is applied to the graph adjustment, the graph to be adjusted is not judged by naked eyes any more, but is subjected to position adjustment according to the information such as the number of edges, the number of vertex angles and the like of the graph, so that the influence of subjective factors of a user on an adjustment result can be reduced, and the accuracy of center alignment adjustment of each graph is improved.
In an embodiment of the present invention, referring to fig. 5, a schematic flow chart diagram of another pattern adjustment method is provided, and compared with the foregoing embodiment shown in fig. 1, in this embodiment, the pattern adjustment method further includes:
step 106: and under the condition that the graph to be adjusted is circular, adjusting the graph to be adjusted directly according to the width of the reference graph, the first position point and the width of the graph to be adjusted, so that the graph to be adjusted is aligned with the center point of the reference graph.
In particular, the radius of the circle being the width
The height and width of the circle are equal. When the circle is adjusted to be aligned with the center point of the reference pattern, since the height and width of the circle are equal to the diameter of the circle, in the implementation process, the calculation and adjustment of the pattern can be performed by obtaining the height, radius, diameter of the circle, the height of the circumscribed rectangle, the width of the circumscribed rectangle, and the like, which is not limited.
The following is an example of obtaining the width of the pattern to be adjusted.
The abscissa x2 and the ordinate y2 of the target point may be calculated according to the following expression, and the pattern to be adjusted may be adjusted by adjusting the second position point to the target point:
wherein the second location points are: points for indicating the position of the pattern to be adjusted, w1 the width of the reference pattern, w2 the width of the pattern to be adjusted, r1 the radius of the circumscribed circle of the reference pattern, and x1 and y1 the abscissa and ordinate respectively indicating the point of the first position.
Specifically, the first position point and the second position point are points representing positions of the reference pattern and the pattern to be adjusted, respectively. The first position point may be a center point of the reference pattern, or may be any vertex of a circumscribed rectangle of the reference pattern. The second position point may be a center point of the graph to be adjusted, or may be any vertex of a circumscribed rectangle of the graph to be adjusted.
Taking a circle as a reference graph as an example, assuming that the circle with the width of 40 pixel points is a graph to be adjusted, a vertex at which a left vertical edge and an upper horizontal edge of a circumscribed rectangle of the reference graph intersect is taken as a first position point, and a vertex at which the left vertical edge and the upper horizontal edge of the circumscribed rectangle of the graph to be adjusted intersect is taken as a second position point. Wherein the reference pattern has a width of 20 pixel points, a radius of 10 pixel points, and a first position point coordinate of (10, 10); if the width of the graph to be adjusted is 20 pixel points, the coordinates of the target points can be calculated by the following formula:
the coordinates of the target point are (0, 20). And adjusting the graph to be adjusted to be aligned with the center point of the reference graph by moving the graph to be adjusted to adjust the second position point to the coordinates of the target point.
Therefore, when the scheme provided by the embodiment of the invention is applied to pattern adjustment of a circle, the width of the circle can be directly obtained, the pattern to be adjusted is adjusted according to the width of the first position point and the reference pattern, the calculation steps are simplified, and the pattern to be adjusted and the reference pattern can be adjusted to be aligned to the central point more conveniently and quickly.
