Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments, and all other embodiments obtained by those skilled in the art without making any inventive effort based on the embodiments of the present invention are within the scope of protection of the present invention.
As described above, in the related art, if a user wants to capture a three-dimensional topological structure, the user usually uses capture software to select the content and the size of the capture for the full-screen capture or manually dragging the capture frame, so that the capture of the target topological structure can be obtained, and the capture is displayed for the user. However, the display area used to display the screenshot is typically sized, which can cause problems with the mismatch in the size ratio of the screenshot to the display area, thereby affecting the user experience.
In order to solve the technical problem, the inventor can consider the problem that the size ratio of the screenshot to the region to be displayed is not matched due to full screen screenshot or manual dragging of the screenshot frame by determining the second size information of the screenshot frame for intercepting the target topological structure based on the three-dimensional coordinate information of each target topological element in the target topological structure selected by the user and the first size information of the region to be displayed and centering the target topological structure in the screenshot frame.
Specific implementations of the above concepts are described below.
Referring to fig. 1, an embodiment of the present invention provides a screenshot method of a three-dimensional topology structure, including:
Step 100: responding to the triggering operation of a user, and determining a target topological structure from the three-dimensional topological structure; the target topological structure comprises target topological elements and three-dimensional coordinate information of each target topological element, and the target topological elements comprise at least one of topological nodes, text prompts and node frames;
step 102: determining second size information of a screenshot frame for intercepting the target topological structure based on the three-dimensional coordinate information of each target topological element and the first size information of the region to be displayed; the region to be displayed is used for displaying the screenshot of the target topological structure;
step 104: and based on the three-dimensional coordinate information and the second size information of each target topological element, centering the target topological structure in the screenshot frame to finish screenshot of the target topological structure.
In the embodiment of the invention, firstly, each target topological element in the target topological structure selected by a user from the three-dimensional topological structure is determined, then, based on the three-dimensional coordinate information of each target topological element and the first size information of the region to be displayed, the second size information of the screenshot frame for intercepting the target topological structure is determined, and finally, based on the three-dimensional coordinate information of each target topological element and the second size information, the centering treatment is carried out on the target topological structure in the screenshot frame so as to finish the screenshot of the target topological structure, thus, the problem that the size ratio of the screenshot to the region to be displayed is not matched can be solved, and the user experience is improved.
The manner in which the individual steps shown in fig. 1 are performed is described below.
For step 100:
the user can use a man-machine interaction mode to click on the target topological elements in sequence by using a mouse to determine the target topological structure, and can select the target topological structure by moving the frame selection area, so the mode of determining the target topological structure by the user is not particularly limited.
For example, as shown in fig. 2, which is a schematic diagram of a three-dimensional topology structure, the diagram includes topology nodes, connection relationships, text prompts, and node frames, and a user can select a desired target topology element to determine a desired target topology structure. Each target topological element has a unique identification ID, and three-dimensional coordinate information of the target topological element can be obtained through the unique identification ID.
It should be noted that, when the user selects two topology nodes and there is a connection relationship between the two topology nodes, the connection relationship is selected by default, and the connection relationship does not need to be selected additionally.
In some embodiments, after step 100, it may further include:
the topology elements other than the target topology are hidden from the three-dimensional topology.
In this embodiment, all topology elements in the three-dimensional topology structure are traversed, in the traversing process, a target topology element determined by a user is identified according to a unique identification ID, so that topology elements except for the target topology element in the target topology structure are hidden, and after the screenshot is completed, the hidden topology elements can be redisplayed according to the identification ID of the hidden topology element. Therefore, the topology elements except the target topology structure are hidden, the screenshot can be more targeted, and the screenshot of the target topology structure is more concise and clear, so that the user experience can be improved.
It should be noted that, since the topology structure includes the topology nodes and the connection relationships between the topology nodes, in the case where only one end of the topology nodes is selected by the user and the other end of the topology nodes is not selected by the user, the connection relationships between the two topology nodes are also hidden.
In addition, the background color and transparency of the three-dimensional topological structure can be set, so that the screenshot of the target topological structure is more attractive, and the user experience is further improved.
In some embodiments, step 102 may include:
converting three-dimensional coordinate information of each target topological element into two-dimensional coordinate information;
determining third dimension information of the target topological structure based on the two-dimensional coordinate information of each target topological element; wherein the third dimension information includes a maximum lateral dimension and a maximum longitudinal dimension between each target topological element;
and determining second size information of a screenshot frame for intercepting the target topological structure based on the third size information and the first size information of the region to be displayed.
In this embodiment, the screenshot viewing angle can be regulated and controlled by using a man-machine interaction mode, and then the three-dimensional coordinate information of each target topological element can be mapped onto the two-dimensional plane of the regulated and controlled screenshot viewing angle, so as to obtain the two-dimensional coordinate information of each target topological element in the screenshot viewing angle. And then comparing the two-dimensional coordinate information of all the target topological elements, and determining the minimum abscissa, the maximum abscissa, the minimum ordinate and the maximum ordinate in the two-dimensional coordinate information of all the target topological elements to obtain the third size information of the target topological structure. And finally, determining second size information of a screenshot frame for intercepting the target topological structure based on the third size information and the first size information of the region to be displayed, so that the problem that the size ratio of the screenshot to the region to be displayed is not matched is solved, and user experience is improved.
In the present embodiment, the maximum lateral dimension and the maximum longitudinal dimension in the third dimension information can be calculated according to the following formulas:
w＝max x-min x
h＝max y-min y
wherein, min x and max x are respectively the minimum abscissa and the maximum abscissa in the two-dimensional coordinate information of all the target topological elements, min y and max y are the minimum ordinate and the maximum ordinate in the two-dimensional coordinate information of all the target topological elements, w is the maximum transverse dimension between the target topological elements, and h is the maximum longitudinal dimension between the target topological elements.
In the step of determining the second size information of the screenshot frame for intercepting the target topology based on the third size information and the first size information of the region to be displayed, the embodiment of the present invention provides two ways of determining the second size information, and the two ways are described below respectively.
Mode one:
in a first aspect, the determining, based on the third size information and the first size information of the region to be displayed, the second size information of the screenshot frame for capturing the target topology may include:
and when the maximum transverse dimension does not exceed the transverse dimension of the area to be displayed and the maximum longitudinal dimension does not exceed the longitudinal dimension of the area to be displayed, respectively taking the transverse dimension and the longitudinal dimension of the area to be displayed as the transverse dimension and the longitudinal dimension of the screenshot frame for intercepting the target topological structure.
In this embodiment, when the lateral dimension and the longitudinal dimension in the first dimension information of the region to be displayed are respectively greater than or equal to the maximum lateral dimension and the maximum longitudinal dimension in the third dimension information, the lateral dimension and the longitudinal dimension in the first dimension information may be respectively used as the lateral dimension and the longitudinal dimension of the screenshot frame for intercepting the target topological structure, that is, the second dimension information, so as to solve the problem that the size ratio of the screenshot to the region to be displayed is not matched, and improve the user experience.
It should be noted that, when the maximum lateral dimension exceeds the lateral dimension of the area to be displayed and/or the maximum longitudinal dimension exceeds the longitudinal dimension of the area to be displayed, the second size information may be determined in the following manner.
Mode two:
in a second aspect, the determining, based on the third size information and the first size information of the region to be displayed, the second size information of the screenshot frame for capturing the target topology may include:
determining the larger ratio of the maximum transverse dimension to the transverse dimension of the area to be displayed and the ratio of the maximum longitudinal dimension to the longitudinal dimension of the area to be displayed as a scaling ratio;
Taking the product of the transverse dimension of the region to be displayed and the scaling and the product of the longitudinal dimension of the region to be displayed and the scaling as the transverse dimension and the longitudinal dimension of the screenshot frame for intercepting the target topological structure respectively.
In this embodiment, in order to prevent the screenshot from completely intercepting the target topology, the larger ratio of the maximum lateral dimension to the lateral dimension of the region to be displayed and the ratio of the maximum longitudinal dimension to the longitudinal dimension of the region to be displayed is used as the scaling. Then, the product of the transverse dimension of the region to be displayed and the scaling and the product of the longitudinal dimension of the region to be displayed and the scaling are respectively used as the transverse dimension and the longitudinal dimension of the screenshot frame for intercepting the target topological structure, so that the transverse and longitudinal ratios of the screenshot frame for intercepting the target topological structure are ensured to be equal to those of the region to be displayed, namely, the problem that the size ratios of the screenshot and the region to be displayed are not matched is solved, and the user experience can be improved.
For step 104:
for one aspect, step 104 may include:
determining the center point coordinates of the target topological structure based on the two-dimensional coordinate information, the maximum transverse dimension and the maximum longitudinal dimension of each target topological element;
And centering the target topological structure in the screenshot frame based on the center point coordinates and the transverse dimension and the longitudinal dimension of the screenshot frame.
In this embodiment, the center point coordinates may be determined using the following formula:
wherein (X) 0 ,Y 0 ) For the center point coordinates of the target topological structure, max x is the maximum abscissa in the two-dimensional coordinate information of the target topological elements, max y is the maximum ordinate in the two-dimensional coordinate information of the target topological elements, w is the maximum transverse dimension between the target topological elements, and h is the maximum longitudinal dimension between the target topological elements.
The coordinates of the top left corner vertex of the screenshot frame may then be determined using the following formula:
wherein (X, Y) is the top left corner vertex coordinate of the screenshot frame, (X) 0 ,Y 0 ) The imgW and imgH are the lateral and longitudinal dimensions of the screenshot frame, respectively, for the center point coordinates of the target topology.
It should be noted that, in the embodiment of the present invention, the origin of the two-dimensional coordinate system is at the upper left corner, and the coordinate values of the vertical axis downward gradually increase, so (X, Y) is the upper left corner vertex coordinate of the screenshot frame.
In summary, in the first mode, when the maximum lateral dimension does not exceed the lateral dimension of the area to be displayed and the maximum longitudinal dimension does not exceed the longitudinal dimension of the area to be displayed, the lateral dimension and the longitudinal dimension of the area to be displayed can be respectively used as the lateral dimension and the longitudinal dimension of the screenshot frame for intercepting the target topological structure. After the second size information is determined, the coordinates of any one of the four vertexes of the screenshot frame are determined by using the coordinates of the center point of the target topological structure, so that the target topological structure is ensured to be positioned at the center position of the screenshot frame, and after the coordinates of any one vertex are determined, the target topological structure is subjected to screenshot by using the second size information determined in the step 102, so that the screenshot of the target topological structure is completed, the problem that the size ratio of the screenshot to the region to be displayed is not matched is solved, and the user experience is improved.
For mode two, step 104 may include:
and centering the target topological structure in the screenshot frame based on the two-dimensional coordinate information, the maximum transverse dimension, the maximum longitudinal dimension, the transverse dimension and the longitudinal dimension of the screenshot frame of each target topological element.
In this embodiment, the coordinates of the top left corner vertex of the screenshot frame may be determined using the following formula:
wherein (X, Y) is the top left corner vertex coordinate of the screenshot frame, min X is the minimum abscissa in the two-dimensional coordinate information of the target topological elements, min Y is the minimum ordinate in the two-dimensional coordinate information of the target topological elements, w is the maximum transverse dimension between the target topological elements, h is the maximum longitudinal dimension between the target topological elements, and imgW and imgH are the transverse dimension and the longitudinal dimension of the screenshot frame respectively.
It should be noted that, in the embodiment of the present invention, the origin of the two-dimensional coordinate system is at the upper left corner, and the coordinate values of the vertical axis downward gradually increase, so (X, Y) is the upper left corner vertex coordinate of the screenshot frame.
In summary, the second mode may determine a scaling ratio by using the third size information and the first size information of the region to be displayed, and determine the second size information of the screenshot frame for capturing the target topology by using the scaling ratio. After the second size information is determined, the coordinates of any one of the four vertexes of the screenshot frame can be determined to ensure that the target topological structure is located at the center of the screenshot frame, and after the coordinates of any one vertex are determined, the second size information determined in the step 102 is utilized to perform screenshot on the target topological structure so as to complete the screenshot of the target topological structure, so that the problem that the size ratio of the screenshot to the region to be displayed is not matched is solved, and the user experience is improved.
It should be noted that, the screenshot size of the target topology is the second size information, and the second size information may need to be scaled in equal proportion to the first size information of the region to be displayed, but the transverse and longitudinal scales of the second size information are equal to the transverse and longitudinal scales of the region to be displayed, so that the target topology can be ensured not to be deformed even if the scaling is equal.
