At present, when a user needs to perform small-amplitude position alignment adjustment on a specific graphic element, one mode adopted is to enlarge the area where the graphic element is positioned, so as to assist the user in adjusting the position of the graphic element, in this case, the graphic element is sometimes limited by the size of a display screen of a mobile terminal or pixel setting, the condition that the graphic element is displayed in a fuzzy manner occurs, and the user is inconvenient to identify and operate the graphic element; in the other way, the graphic element is dragged by means of the reference line or the grid line, so that the position of the graphic element is adjusted, and in the case, a user sometimes has difficulty in grasping the force for adjusting the graphic element, and the graphic element position is greatly deviated due to the fact that the graphic element is dragged too fast, or the graphic element is dragged too fast, the graphic element position is not obviously changed, the user needs to repeatedly try to continuously adjust the position of the graphic element, so that the whole process is time-consuming and labor-consuming, and the user experience is poor.

Referring to fig. 1, an embodiment of the present application provides a flowchart of a primitive alignment method, as shown in fig. 1, including:
step 101, monitoring displacement of the to-be-adjusted graphic element, and respectively calculating the distance between the to-be-adjusted graphic element and each reference graphic element positioned on the same page;
In the embodiment of the application, the graphic element is simply called graphic element, the page can be any graphic editing page, the page can contain various graphic elements such as button elements, prompt boxes, editing boxes, pictures and the like, the shapes of the graphic element to be adjusted and the reference graphic element are not limited in the embodiment of the application, and the shapes can be regular graphs or irregular graphs.
The graphic element to be adjusted refers to a graphic element moving in a page, the reference graphic element refers to a graphic element which does not move in the page and has a fixed position, and as an optional implementation manner, other graphic elements except the graphic element to be adjusted on the page where the graphic element to be adjusted is located are determined as the reference graphic element.
In implementation, whether the to-be-adjusted graphic element is displaced or not is monitored by monitoring operations such as mouse clicking and mouse dragging of a user, and if the to-be-adjusted graphic element is monitored to be displaced, the distances between the to-be-adjusted graphic element and all the reference graphic elements on the same page are calculated.
102, When at least one reference graphic element with the distance smaller than a first threshold value from the graphic element to be adjusted is monitored, respectively predicting an alignment mode of the at least one reference graphic element, and generating an adsorption line corresponding to the alignment mode;
in the embodiment of the present application, the value of the first threshold is not limited, and may be set according to actual requirements, for example, the first threshold is set to 5 cm, 8 cm, and so on.
In the process of carrying out the graphic element alignment, when the distance between the graphic element to be adjusted and at least one reference graphic element is monitored to be gradually reduced to a first threshold value, determining that the at least one reference graphic element is the graphic element which needs to be aligned for the graphic element to be adjusted, and respectively generating adsorption lines corresponding to the at least one reference graphic element.
For each reference primitive in the at least one reference primitive, when generating the adsorption line corresponding to the primitive to be adjusted and the reference primitive, firstly predicting the alignment mode of the primitive to be adjusted and the reference primitive according to the position relation between the reference primitive and the primitive to be adjusted, and then generating the adsorption line corresponding to the alignment mode according to the predicted alignment mode.
The adsorption line may be in various forms such as a straight line, a radial line, a line segment, etc., and in the embodiment of the present application, the direction of the adsorption line is not limited, and the adsorption line may be a horizontal line or a vertical line in a transverse direction, or may be an oblique line inclined to a certain direction.
As shown in fig. 2, the above alignment includes, but is not limited to, left alignment, right alignment, up alignment, down alignment, and lateral centering alignment, i.e., longitudinal centering alignment.
Step 103, when the target reference graphic element with the distance smaller than the second threshold value from the graphic element to be adjusted is monitored, positioning the alignment position in the graphic element to be adjusted according to the alignment mode corresponding to the adsorption line of the target reference graphic element;
In the embodiment of the present application, the specific value of the second threshold is not limited, but it should be noted that the value of the second threshold needs to be smaller than the value of the first threshold.
In detail, when the distance between the to-be-adjusted primitive and the target reference primitive is further reduced to the second threshold value, positioning the alignment position in the to-be-adjusted primitive according to the generated adsorption line corresponding to the target reference primitive and the alignment mode corresponding to the adsorption line, wherein the alignment position in the to-be-adjusted primitive is the edge point of the to-be-adjusted primitive corresponding to the alignment mode.
Specifically, as shown in fig. 3, the primitive to be adjusted is aligned to the left of the target reference primitive, and the adsorption line is generated on the left edge line of the target reference primitive, where the alignment position of the primitive to be adjusted is selected as the left edge point a of the primitive to be adjusted.
It should be noted that, because the value of the second threshold is smaller than the value of the first threshold, when the distance between the primitive to be adjusted and the target reference primitive is reduced to the second threshold, the adsorption line corresponding to the target reference primitive is necessarily generated in advance.
Step 104, adjusting the position of the primitive to be adjusted, wherein the aligned position in the primitive to be adjusted is overlapped with the adsorption line of the target reference primitive;
In implementation, since the alignment position of the primitive to be adjusted is determined according to the alignment mode corresponding to the adsorption line of the target reference primitive, the alignment position of the primitive to be adjusted is overlapped with the adsorption line of the target primitive, so that the primitive to be adjusted and the target reference primitive can be aligned.
According to the method, the distance between the to-be-adjusted primitive and the reference primitive is calculated in real time, when the distance is reduced to the first threshold value, the adsorption line corresponding to the alignment mode of the reference primitive is generated, when the distance is further reduced to the second threshold value, the alignment position of the to-be-adjusted primitive is determined according to the alignment mode, the position of the to-be-adjusted primitive is adjusted according to the alignment position and the adsorption line, the effect of automatic alignment of the to-be-adjusted primitive and the reference primitive is achieved, and a user does not need to repeatedly adjust or move the to-be-adjusted primitive manually, so that the operation efficiency and the user operation experience of the alignment of the primitives are improved.
As an optional implementation manner, in order to prevent misoperation caused by problems such as hand sliding, adjusting a position of the primitive to be adjusted, and after the aligned position in the primitive to be adjusted is overlapped with the adsorption line of the target reference primitive, further includes:
monitoring an instruction for moving the primitive to be adjusted, and determining the moving speed and/or displacement of the primitive to be adjusted;
when the moving speed is judged to be greater than a preset speed threshold, the position of the primitive to be adjusted is adjusted according to the moving speed, and/or when the displacement is judged to be greater than a preset displacement threshold, the position of the primitive to be adjusted is adjusted according to the displacement;
otherwise, judging the instruction for moving the primitive to be adjusted as an invalid instruction.
In implementation, after the primitive to be adjusted is aligned with the target reference primitive, when the movement of the primitive to be adjusted of a user is monitored, firstly, the movement speed and/or displacement of the primitive to be adjusted are obtained, whether the primitive to be adjusted belongs to misoperation of the user is judged according to the movement speed and/or displacement, if the movement speed is greater than a preset speed threshold value and/or the displacement is greater than a preset displacement threshold value, the operation of the user is judged to be effective operation, and the position adjustment of the primitive to be adjusted is carried out according to the movement speed and/or displacement of the corresponding primitive to be adjusted; otherwise, judging the operation of the user as invalid operation, and not adjusting the position of the primitive to be adjusted.
In the embodiment of the application, the values of the preset speed threshold and the preset displacement threshold are not limited, and can be adjusted according to actual requirements.
It should be noted that, the moving of the primitive to be adjusted may only include moving the primitive to be adjusted aligned with the target reference primitive to a position not aligned with the target reference primitive, or may further include moving the primitive to be adjusted while maintaining the alignment with the target reference primitive, for example, moving the primitive to be adjusted up and down while maintaining the left alignment with the target reference primitive.
According to the method, compared with the movement of the non-aligned primitive to be adjusted, the user moves the aligned primitive to be adjusted, and the movement speed and/or the displacement amount are/is larger, so that the phenomenon of hand sliding can be effectively prevented, and the larger position deviation is avoided when the primitive to be adjusted is moved.
Referring to fig. 4, in the following step 101, a method for calculating a distance between a to-be-adjusted primitive and each reference primitive located on the same page is described in detail, and the method for calculating a distance between a to-be-adjusted primitive and each reference primitive located on the same page includes the following steps:

In implementation, when selecting the reference points on the primitive to be adjusted and each reference primitive, an alternative implementation manner is to determine the reference points on the primitive to be adjusted and each reference primitive according to the predefined reference point position, for example, define the center point of the primitive as the reference point of the primitive in advance; in another alternative embodiment, an edge detection algorithm is used to obtain the edge profiles of the primitives to be adjusted and the reference primitives, and the corresponding reference points are determined according to the edge profiles, for example, any vertex in the edge profile is used as the reference point of the corresponding primitive.
As an optional implementation manner, selecting a reference point on the primitive to be adjusted and the reference primitive respectively includes:
Respectively determining the edge contours of the primitives to be adjusted and the reference primitives by using an edge detection algorithm;

It should be noted that, the reference points selected on the primitives to be adjusted are selected according to the corresponding reference primitives, and the reference points selected on the primitives to be adjusted may be the same or different for different reference primitives.
It should be noted that if there are multiple sets of first points and second points in the edge contour point set of the primitive to be adjusted and the edge contour point set of the reference primitive, it is possible to achieve that the first points and the second points are closest to each other, any one of the first points and the second points is selected, the first point is determined as the reference point of the primitive to be adjusted, and the second point is determined as the reference point of the reference primitive.

in step 603, the auxiliary line corresponding to the closest alignment mode is predicted to be the adsorption line according to the positions of the primitive to be adjusted and at least one reference primitive.
In implementation, the auxiliary lines corresponding to the various alignment manners in the step 602 may be multiple, and the root may be an alternative implementation, where the auxiliary lines include at least one of the following:
