Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The embodiment of the application provides a graph adjusting method and a graph adjusting device, which are respectively described in detail below.
First, an execution subject of the graphic adjustment scheme provided by the embodiment of the present application will be described.
The execution subject may be a software client. For example, the file processing may be performed by a software client such as WPS, word, PDF, or may be performed by a software client for graphics processing.
In addition, the execution body may be an electronic device running the software client. Such as desktop computers, notebook computers, tablet computers, smart phones, and the like.
The graphic adjustment method provided by the embodiment of the application is described below through a specific embodiment.
Referring to fig. 1, fig. 1 is a flowchart of a graphic adjustment method according to an embodiment of the present application, where the method includes the following steps 101 to 104.
Step 101, obtaining the number of edges and the height of the polygon to be adjusted.
Specifically, the polygon to be adjusted may be a regular polygon or a non-regular polygon, which is not limited by the present application.
The height of the polygon to be adjusted may be the height of its circumscribed rectangle. For example, as shown in fig. 2, the hexagon is a polygon to be adjusted, the rectangle circumscribed by the hexagon in the figure, and the length of the vertical side of the circumscribed rectangle represents the height of the circumscribed rectangle, so the height of the hexagon may be the height of the circumscribed rectangle.
The height of the polygon to be adjusted may be the height of a vertical line segment from a vertex of the polygon to be adjusted to the opposite side. For example, as shown in fig. 3, the pentagon is a polygon to be adjusted, and the line segment marked with the "height" word is a vertical line segment from one vertex to the opposite side of the pentagon, so the length of the line segment marked with the "height" word may be the height of the pentagon.
In one implementation of the present application, the number of sides and the height of the polygon may be obtained by obtaining the number of sides and the height of the polygon input by the user. For example, the electronic device may generate a dialog box in the display interface, and the user inputs the number of sides and the height of the polygon to be adjusted in the dialog box, so that the electronic device obtains the number of sides and the height input by the user.
In another implementation manner of the present application, vertices of the polygon to be adjusted may be identified, coordinates of the identified vertices may be obtained, the number of sides of the polygon to be adjusted may be calculated according to the number of the identified vertices, and the height of the polygon to be adjusted may be calculated according to the coordinates of the identified vertices.
In another implementation manner of the application, the height of the circumscribed rectangle of the polygon to be adjusted can be obtained, and the obtained height is used as the height of the polygon to be adjusted.
Step 102, calculating the distance from the center point to the vertex of the regular polygon determined by the obtained edge number and the height.
In one embodiment of the present application, the above distance r may be calculated from the following expression:
wherein h represents the acquired height, n represents the acquired edge number, 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 sides of the polygon to be adjusted is 3 and the height is 20 pixels, the distance from the center point to the vertex of the regular triangle with the height of 20 pixels can be calculated according to the above formula:
from the calculation, the distance from the center point to the vertex of the regular triangle with the height of 20 pixels is 13 pixels.
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 application are merely described by way of example, and are not limited to the configurations provided by the embodiments of the present application.
And step 103, calculating the width of the regular polygon determined by the acquired edge number and height according to the distance from the center point to the vertex of the regular polygon.
The inventor finds that the characteristics are different when the polygons have different edge numbers in the experimental process. In view of this, in one embodiment of the present application, if the number of sides of the polygon to be adjusted is an even number, the width w of the regular polygon determined by the acquired number of sides and height is calculated according to the following expression:
wherein mod represents a remainder operator, h represents the acquired height, n represents the acquired edge number, r represents the distance from the center point to the vertex of the regular polygon, and d represents a preset parameter.
Specifically, the value of d may be 4. In this case, if the number of edges of the polygon to be adjusted is 6 and the height is 20 pixels, the width of the regular hexagon with the height of 20 pixels can be calculated according to the above formula:
from the calculation, the width of the regular hexagon with the height of 20 pixels is 23 pixels.
In addition to the above, the value of d may be other values, for example, d may be 3, 5, 6, etc. The embodiments of the present application are merely described by way of example, and are not limited to the configurations provided by the embodiments of the present application.
In another embodiment of the present application, if the number of sides of the polygon to be adjusted is an odd number, the width w of the regular polygon determined by the acquired number of sides and height is calculated according to the following expression:
wherein n represents the acquired edge number, r represents the distance from the center point to the vertex of the regular polygon, and e and f represent preset parameters.
Specifically, the value of e may be 5, and the value of f may be 4. In this case, if the number of edges of the polygon to be adjusted is 3 and the height is 20 pixels, the width of the regular triangle with the height of 20 pixels can be calculated according to the above formula, which is:
from the calculation, the width of the positive triangle with the height of 20 pixels is 23 pixels.
In addition to the above, the values of e and f may be other values, for example, e may be 3, 4, 6, etc., and f may be 2, 3, 5, etc. The embodiments of the present application are merely described by way of example, and are not limited to the configurations provided by the embodiments of the present application.
And 104, under the condition that the height of the polygon to be adjusted is kept unchanged, adjusting the width of the polygon to be adjusted to be the calculated width to obtain an adjusted polygon with equal vertex angles.
The polygon to be adjusted may be adjusted in a plurality of different ways, which will be described below.
In one implementation manner of the present application, since the number of vertices of the polygon to be adjusted is also determined when the number of edges of the polygon to be adjusted is determined, in view of this, the angles of each vertex may be calculated according to the number of vertices of the polygon to be adjusted when the vertices are equal, that is, when the angles of each vertex are equal, and then the width of the polygon to be adjusted is adjusted to the calculated width and the angles of each vertex are adjusted to the calculated angles while ensuring that the height of the polygon to be adjusted is unchanged.
In another implementation manner of the application, the adjustment of the polygon to be adjusted can be realized by adjusting the circumscribed rectangle of the polygon to be adjusted. And under the condition of keeping the height of the polygon to be adjusted unchanged, adjusting the width of the circumscribed rectangle of the polygon to be adjusted to the width of the regular polygon obtained by calculation, and obtaining the adjusted polygon with equal vertex angles and equal side lengths.
Therefore, when the scheme provided by each embodiment of the application is applied to adjust the graph, the width of the polygon to be adjusted is adjusted to be the calculated width because the calculated width is the width of the regular polygon, and the vertex angles of the adjusted polygons are equal, so that the adjusted polygons can be considered to be the regular polygons. Compared with the prior art, when the scheme provided by the embodiment of the application is used for polygon adjustment, the polygon to be adjusted is adjusted according to the width of the regular polygon obtained by calculation without depending on naked eyes, so that the probability of the regular polygon is higher, and when the scheme provided by each embodiment is used for polygon adjustment, the probability of the regular polygon can be improved.
In an embodiment of the present application, referring to fig. 4, a flowchart of another graphic adjustment method is provided, and compared with the embodiment shown in fig. 1, in the embodiment, step 104, while keeping the height of the polygon to be adjusted unchanged, adjusts the width of the polygon to be adjusted to the calculated width, and the adjusted polygon with equal vertex angles includes the following steps:
step 104A, determining the adjusting point information according to the acquired edge number.
And the adjusting point information is used for indicating the position of an adjusting point of the regular polygon determined by the acquired edge number and the acquired height, and the adjusting point is used for adjusting the edge length and the angle of each vertex angle of each edge of the polygon.
Specifically, the adjustment point may be located on one side of the polygon to be adjusted and the external rectangle, where the information of the adjustment point is: information determined by the position of the adjustment point on the circumscribed rectangle.
Regarding the adjustment point information, the embodiments of the present application provide the following two implementations.
In a first aspect, the adjustment point information may be: the ratio of the lengths of two sides of a triangle to be connected of the polygon to be adjusted, wherein the triangle to be connected is: the triangle formed by the first side, the second side and the third side, wherein the first side is the side where the adjusting point is located on the circumscribed rectangle, and the second side is: the third side is the side adjacent to the first side along the preset direction in the circumscribed rectangle: edges intersecting both the first edge and the second edge on the polygon to be adjusted. The adjusting point information may be a ratio of the first side to the second side, a ratio of the first side to the third side, a ratio of the second side to the first side, a ratio of the third side to the first side, or a ratio of the third side to the second side.
Specifically, the ratio of the lengths of two sides in the connected triangle may be the ratio of the lengths of any two sides in the connected triangle, as shown in fig. 5, and the value of the information of the adjustment point of the hexagon may be the ratio of the lengths of any two sides of the first side, the second side and the third side.
In one embodiment of the present application, the adjustment point information is a ratio of the second side to the third side. The adjustment point information is denoted by p.
Specifically, if the pattern to be adjusted is hexagonal, the p value may be:
if the pattern to be adjusted is octagonal, the p-value size may be:
in addition, the predetermined direction may be any direction of two sides of the first edge. For example, when the first side is a horizontal side of the circumscribed rectangle, the second side may be a vertical side adjacent to the first side on the left side of the first side in the circumscribed rectangle, and the second side may be a vertical side adjacent to the first side on the right side of the first side in the circumscribed rectangle. When the first side is a vertical side of the circumscribed rectangle, the second side may be a horizontal side adjacent to the first side on the upper side of the first side in the circumscribed rectangle, and the second side may also be a horizontal side adjacent to the first side on the lower side of the first side in the circumscribed rectangle.
In a second aspect, the adjustment point information may be: the ratio of the lengths of two line segments in the line segments corresponding to the edges of the regulating points in the circumscribed rectangle of the polygon to be regulated.
The line segments corresponding to the edges of the adjusting points comprise a first line segment, a second line segment and a third line segment. The first line segment is a line segment from one end point of the side of the regulating point on the external rectangle to the regulating point, the second line segment is a line segment from the other end point of the side of the regulating point on the external rectangle to the regulating point, the third line segment is a line segment between the two end points of the side of the regulating point on the external rectangle, and the ratio of the two line segments of the side of the regulating point in the external rectangle of the polygon to be regulated is the ratio of the lengths of any two line segments in the three line segments. The adjusting point information can be the length ratio of the first line segment to the second line segment, the length ratio of the first line segment to the third line segment, the length ratio of the second line segment to the first line segment, the length ratio of the third line segment to the first line segment, and the length ratio of the third line segment to the second line segment.
And 104B, adjusting the adjusting points of the polygon to be adjusted to the positions of the adjusting points of the regular polygon determined by the obtained edge numbers and the heights according to the adjusting point information, so that the width of the polygon to be adjusted is adjusted to be the calculated width under the condition that the heights of the polygon to be adjusted are kept unchanged, and the adjusted polygon with the same vertex angles is obtained.
Since the adjusting point information can determine the adjusting point position, the adjusting point information calculated in step 104A is the adjusting point information of the regular polygon, and the adjusting point of the graph to be adjusted is adjusted to the position indicated by the calculated adjusting point information, that is, the graph to be adjusted is adjusted to the regular polygon, that is, the adjusted regular polygon is adjusted to have equal vertex angles and equal side lengths.
Therefore, the adjustment points are utilized for adjustment, the vertex angles and the side lengths of the polygons to be adjusted can be directly adjusted, and the polygons to be adjusted can be more conveniently and rapidly adjusted into the adjusted polygons with equal side lengths and equal vertex angles.
