[0034] In order to make the technical problems, technical solutions and advantages to be solved by the present application clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0035] In the technical solution of the embodiment of the present application, the first operation event in the layout is captured to determine the area in the layout where the path angle adjustment is to be performed and the selected path in the area is determined; the second operation event in the layout is captured to determine multiple selected vertices in the selected path, and a selection mark is assigned to each selected vertex; for each of the two vertices of the selected path, one vertex is selected one by one as the target vertex based on the corresponding selection mark; the coordinates of the target vertex are obtained to determine the preceding line segment and the succeeding line segment that take the target vertex as the vertex in the layout; the angle and length data of the preceding line segment, as well as the length and angle data of the succeeding line segment are obtained; the angle and length data of the preceding line segment are kept unchanged, as well as the length data of the succeeding line segment, and the angle data of the succeeding line segment is changed so that the angle of the succeeding line segment is adjusted to the set target angle, thereby realizing automatic adjustment of the path angle and avoiding the problems of inefficiency and easy errors caused by manually dragging vertices to change the path angle.

[0036] The solution of the following embodiment is to optimize the path angle of the layout after the layout is preliminarily designed using design software.

[0037] Figure 1 This is a schematic diagram of a method for adjusting the path angle in a layout according to an embodiment of the present application; Figure 1 Said, it includes:

[0038] S101, capturing a first operation event in a layout to determine an area in the layout where a path angle adjustment is to be performed and determining a selected path in the area;

[0039] Optionally, in this embodiment, capturing the first operation event in the layout includes: monitoring a selection action of a cursor in the layout, and generating the first operation event in response to the monitored selection action to capture the first operation event.

[0040] In this embodiment, the first operation event can be captured quickly and accurately by monitoring the selection action of the cursor in the layout. The selection action of the cursor can be operated by the user or automatically implemented by a script.

[0041] In this embodiment, the cursor may be controlled by a mouse or by a touch screen.

[0042] In this embodiment, the frame selection action may be any action that can delimit a certain area, such as realizing frame selection by using the diagonal vertex positions, or realizing frame selection by continuously drawing a certain range.

[0043] Optionally, in this embodiment, the capturing of the first operation event in the layout to determine the area in the layout where the path angle adjustment is to be performed and determining the selected path in the area includes:

[0044] Capturing the first operation event in the layout;

[0045] Determine, according to the captured first operation event, an area in the layout where a path angle adjustment is to be performed;

[0046] According to the path selection event generated in the area where the path angle adjustment is to be performed, the selected path in the area is determined.

[0047] In this embodiment, the first operation event can be used to determine the area in the entire layout that requires path angle adjustment, while for the area that does not require the adjustment, there is no need to capture the first operation event, thereby improving the speed and efficiency of layout adjustment, reducing the amount of data processing, and improving data processing efficiency.

[0048] In this embodiment, the above description of step S101 is only an example and is not intended to be exclusive. In fact, for those skilled in the art, it is possible to indicate the area in the publication diagram where the path angle is to be adjusted without relying on the cursor or the frame selection action.

[0049] S102, capturing a second operation event in the layout to determine a plurality of selected vertices in the selected path, and assigning a selected mark to each selected vertex;

[0050] Optionally, in this embodiment, capturing the second operation event in the layout includes: monitoring a click action of a cursor in the layout, and generating the second operation event in response to the monitored click action to capture the second operation event.

[0051] In this embodiment, the click action of the cursor in the layout can be realized by the designer through mouse operation, or can be realized by the designer touching the cursor displayed on the display screen.

[0052] In addition, in this embodiment, monitoring the click action of the cursor in the layout is only one way to generate the second operation event, and is not limited to a unique way.

[0053] S103, for each of the two vertices of the selected path, based on the corresponding selection mark, one vertex is selected one by one as the target vertex;

[0054] The method selects one vertex from each of the two vertices of each selected path as the target vertex based on the corresponding selection mark, including: for each of the two vertices of the selected path, based on the corresponding selection mark, according to the order of drawing, selects the vertex drawn first as the target vertex.

[0055] Optionally, in this embodiment, it also includes: obtaining vertex drawing log data, parsing the vertex log data, and determining the drawing order of two vertices of each selected path according to the result of the parsing; the processing step of the vertex log data here can be performed in step S103, or before step S103, such as further performed before step S101.

[0056] Here, drawing the vertex log data based on the vertex is only one possible way to determine the drawing order of the vertices, and those skilled in the art may also determine the drawing order in other ways.

[0057] In this embodiment, for all paths in the area where the path angle adjustment is to be performed, if two paths are connected together, the last vertex of the previous path is the first vertex of the latter path. Therefore, by selecting the first drawn vertex as the target vertex for the two vertices of each selected path based on the corresponding selection mark and in the order of drawing, the angle of each path that needs to be adjusted can be automatically adjusted one by one, thereby improving the efficiency and accuracy of the angle adjustment.

[0058] S104, obtaining the coordinates of the target vertex to determine a preceding line segment and a succeeding line segment that take the target vertex as a vertex in the layout;

[0059] In this embodiment, for the previous line segment (i.e., the previous path), the target vertex is the last vertex, and for the next line segment (i.e., the next path), the target vertex is the first vertex. Therefore, based on this relationship, the next line segment is directly taken as the object to be directly processed to quickly adjust the angle.

[0060] S105, obtaining the angle and length data of the preceding line segment, and the length and angle data of the succeeding line segment;

[0061] In this embodiment, the coordinates of the target vertex can be obtained from the vertex drawing log data. Of course, obtaining from the vertex drawing log data here is only an example and is not a unique limitation.

[0062] In other embodiments, during the vertex drawing process, all data to be used in the embodiments of the present application, such as the coordinates of the target vertex, the angle and length data of each path, can be stored separately so that they can be quickly obtained when used, thereby improving the speed and efficiency of the method execution and facilitating fast and accurate angle adjustment.

[0063] S106: Keep the angle and length data of the previous line segment unchanged, keep the length data of the next line segment unchanged, and change the angle data of the next line segment so that the angle of the next line segment is adjusted to the set target angle.

[0064] Optionally, in the present embodiment, the maintaining the angle and length data of the preceding line segment unchanged, and maintaining the length data of the succeeding line segment unchanged, and changing the angle data of the succeeding line segment so that the angle of the succeeding line segment is adjusted to a set target angle, includes: maintaining the angle and length data of the preceding line segment unchanged, and maintaining the length data of the succeeding line segment unchanged, and changing the angle data of the succeeding line segment so that the angle of the succeeding line segment is adjusted to the set target angle along a direction smaller than a preset angle.

[0065] Optionally, in this embodiment, the preset angle is 180 degrees, so as to quickly adjust to the target angle.

[0066] Optionally, in this embodiment, the method also includes: obtaining grid capture configuration data, determining whether grid capture is turned on based on the grid capture configuration data, and if it is turned on, adjusting the angle of the subsequent line segment to a set target angle, and aligning the subsequently drawn vertex with the nearest grid vertex position.

[0067] In this embodiment, when changing the angle data of the subsequent line segment, the position of the target vertex is kept unchanged, that is, its coordinates do not change. Therefore, when changing the angle data of the subsequent line segment, the coordinates of another vertex of the subsequent line segment will change with the change of the angle of the subsequent line segment. Therefore, based on the above-mentioned grid capture configuration data, alignment with the grid vertex position can be achieved, thereby ensuring the accuracy of the layout.

[0068] Optionally, in this embodiment, for example, if the value of the grid capture configuration data is 1, it indicates that it is turned on, otherwise it indicates that it is not turned on, or it is also called closed.

[0069] Optionally, in this embodiment, after adjusting the angle of the subsequent line segment to the set target angle, it includes: determining whether the adjusted path is self-intersecting, if so, generating an error message, and restoring the self-intersecting path to the angle before adjustment.

[0070] In this embodiment, when executing the above method, steps S103-S106 may be executed in parallel with a single path as a reference, or traversed with respect to a single path and executed sequentially.
