For example, when a user is in the global state and needs to zoom in on a certain location to view detailed location information of that location and its vicinity in advance, this view display method cannot meet the user's needs. Summary of the Invention

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] Pango Design Suite is a large-scale field-programmable gate array (FPGA) development software. In Pango Design Suite, the view display method is based on the zoom level of the view to display the position information included in the current level. That is, the user needs to go to the corresponding display level to view the position information contained in that level.

[0018] When users need to view detailed location constraint information, they need to zoom in to the corresponding level step by step, which is relatively time-consuming and laborious. For example, when a user is in the global state and needs to zoom in on a certain location to view detailed location information of that location and its vicinity in advance, the above view display method cannot meet the user's needs, resulting in low view display efficiency.

[0019] To address the aforementioned issues, the inventors have proposed a view display method, apparatus, and storage medium as described in this application. The method includes: generating a first backup view based on original view information; upon receiving a view zoom-in command, zooming in on the first backup view based on the first backup view information to obtain a zoomed-in view; acquiring a first target area and cropping the first backup view accordingly based on the first target area to obtain a cropped second backup view; and overlaying the second backup view onto the zoomed-in view to display a target zoomed-in area, where a corresponding zoomed-in view is displayed. By generating a first backup view identical to the original view display information using the original view information, and generating a zoomed-in view and a second backup view based on the first backup view, the second backup view is overlaid on the zoomed-in view. This determines the target zoomed-in area within the first target area, allowing the user to zoom in on any location even when in a global view state, thereby improving view display efficiency.

[0020] Please see Figure 1 , Figure 1 A flowchart illustrating a view display method provided in an embodiment of this application is shown. The method may include steps 110 to 140.

[0021] In step 110, a first backup view is generated based on the original view information.

[0022] In this embodiment, the original view can refer to the view displayed when the system is in a global state. The original view can be composed of multiple layers of information, each layer can display different detailed position information, and the position information can indicate the components presented in the view. The underlying information of the original view can include the information presented by the original view. In addition, the layer information of the original view can also include corresponding parameter information, such as constraint coefficients, magnification coefficients, and specification coefficients. For example, the constraint coefficients can constrain the position information of the original view.

[0023] In this embodiment, the original view information can indicate the hierarchical information contained in the original view. The parameter information and underlying information in the original view information are backed up and saved. Based on the backed-up parameter information and underlying information, a first backup view is generated. That is, the first backup view has the same parameter information and underlying information as the original view, and the information displayed in the first backup view is the same as that in the original view. By backing up and saving the parameter information and underlying information in the original view information, and then generating the first backup view based on the backed-up parameter information and underlying information, the possibility of irrecoverable damage after the parameter information and underlying information in the original view information have been changed can be reduced.

[0024] In step 120, when a view zoom-in instruction is received, the first backup view is zoomed in based on the first backup view information to obtain a zoomed-in view.

[0025] In this embodiment, the first backup view information indicates the parameter information and underlying information contained in the first backup view. Based on the parameter information of the first backup view, the magnification factor of the first backup view is determined. The magnification factor can be preset in the parameter information. In other embodiments, the magnification factor can be obtained by user input. For example, the user can manually input the magnification factor into the system or select the specific value of the magnification factor using a mouse. Based on the magnification factor, the position information in the first backup view is magnified to obtain a magnified view.

[0026] In this embodiment, the magnified view and the original view have the same constraint effect; that is, when the user imposes a positional constraint on the magnified view, the corresponding position in the original view will also be subject to a positional constraint. Furthermore, when an adjustment command is received, zooming in or out can be performed based on the magnified view to make the magnification effect more pronounced or to reduce the magnification effect, thereby making the presentation of the magnified view closer to the user's needs and improving the user experience.

[0027] In step 130, a first target region is obtained, and the first backup view is cropped accordingly based on the first target region to obtain a cropped second backup view.

[0028] In this embodiment, the first target area indicates the target area that the user needs to zoom in on. The user can select the first target area by dragging with the mouse or by touching the screen.

[0029] The specific steps for obtaining the first target area may include: obtaining the first center position and radius information; wherein, the first center position may be the position of the mouse when the system receives the view zoom command, or in other embodiments, the first center position may be the position corresponding to the coordinate information input by the user in the first backup view; the user may input the corresponding radius information to the system according to actual usage needs, and the radius information may indicate the radius value; the first target area is determined based on the first center position and radius information; the larger the radius, the larger the range of the first target area.

[0030] In this embodiment of the application, the first target area is removed from the first backup view, and a region gap appears in the first backup view at the position corresponding to the first target area, thus obtaining the second backup view. That is, the difference between the second backup view and the first backup view is that the second backup view has a region gap at the corresponding position of the first target area.

[0031] In step 140, the second backup view is overlaid on the magnified view to display the target magnified area, and the corresponding magnified view is displayed in the target magnified area.

[0032] In this embodiment of the application, since the second backup view is obtained by cropping the first target area from the first backup view, the second backup view covers the magnified view. On the first target area that is missing in the second backup view, the corresponding magnified view can be displayed, thereby determining the target magnified area. In other words, the target magnified area is the area determined by the magnified view based on the first target area.

[0033] When a view zoom-in cancellation command is received, the zoom-in effect of the zoomed-in view is adjusted to be the same as the display effect of the second backup view based on the parameter information of the original view. At this time, the second backup view overlaps with the zoomed-in view, and the second backup view will not display the zoomed-in information in the first target area, thereby canceling the zoom-in effect in the first target area.

[0034] In this embodiment, when a drag command is received, a second target area is obtained. The specific method for obtaining the second target area may include: obtaining a second center position; the second center position may be the position of the mouse when the system receives the drag command; in other embodiments, the second center position may be the coordinate information input by the user and its position in the first backup view; the radius information of the second target area may be the same as the radius information of the first target area; in other embodiments, the radius information of the second target area may be manually input by the user; based on the second center position and radius information, the second target area is determined, and the second target area is removed from the second backup view to obtain the removed second backup view.

[0035] Based on the first target region and the second target region, the intersection region of the first target region and the second target region is determined, that is, the intersection region is indicated by the area where the first target region and the second target region overlap. When the first target region and the second target region overlap, that is, the intersection region is not an empty set, the portion of the first target region corresponding to the intersection region is removed to obtain the removed first target region. Based on the original view information, the display of the corresponding removed first target region in the second backup view is restored. When there is no overlap between the first target region and the second target region, the intersection region is an empty set, and the display of the corresponding first target region in the second backup view is restored based on the original view information.

[0036] As described above, this embodiment generates a first backup view with the same parameter information and underlying information as the original view using the original view information. When a view zoom-in command is received, the first backup view is zoomed in based on the parameter information in the first backup view to obtain a zoomed-in view. A first target area to be zoomed in is obtained, and the first backup view corresponding to the first target area is cropped to obtain a cropped second backup view. The second backup view is then overlaid on the zoomed-in view to determine the target zoom-in area, i.e., the target zoom-in area displays the portion of the zoomed-in view corresponding to the first target area. Therefore, when the user is in global mode, the user can zoom in on any location to view detailed location information.

[0037] Please see Figure 2 , Figure 3 and Figure 4 , Figure 2 A flowchart illustrating a view display method according to another embodiment of this application is shown. Figure 3 This paper presents a schematic diagram of a second backup view, a magnified view, and a target magnified area according to an embodiment of this application. Figure 4 The diagram shows a first center, a second center, and a first target region provided in an embodiment of this application. The method may include steps 210 to 301.

[0038] In step 210, when a view zoom-in command is received, a backup process is performed based on the parameter information and underlying information of the original view.

[0039] In this embodiment, the parameter information and underlying information of the original view are backed up and saved, which facilitates the subsequent generation of the corresponding view using the backed-up parameter information and underlying information. This avoids directly generating the corresponding view based on the parameter information and underlying information of the original view, and reduces the possibility of the parameter information or underlying information of the original view being unrecoverable.

[0040] In step 220, a first backup view is generated based on the backup parameter information and underlying information.

[0041] In the embodiments of this application, the parameter information and underlying information of the first backup view are the same as those of the original view, that is, all the information displayed by the first backup view is the same as that of the original view.

[0042] In step 230, the magnification factor is determined based on the parameter information of the first backup view.

[0043] In this embodiment, the magnification factor can be preset by the system or determined based on the density of information displayed in the original view, such as the density of components presented in the view. In other embodiments, the magnification factor can also be input by the user.

[0044] In step 240, the position information in the first backup view is magnified based on the magnification factor to obtain an enlarged view.

[0045] In this embodiment of the application, the position information can indicate the information displayed at the corresponding position in the original view, such as the components presented at the corresponding position, i.e., the information displayed at the corresponding position in the first backup view. The position information of the first backup view is magnified based on the magnification factor, for example, the specifications of the components are magnified. The position information of the magnified view is the effect of magnifying the information at the corresponding position in the original view or the first backup view.

[0046] In step 250, the position and radius information of the first circle center are obtained to determine the first target area.

[0047] In this embodiment, the first center position can indicate the position of the mouse on the system interface when a zoom-in command is received, and the radius information can be any value input by the user to the system. In other embodiments, the radius information can be a value specified by the system.

[0048] It is worth noting that the first center can be located within the first backup view or outside the second backup view. When the first center is located outside the first backup view, the system does not respond to the zoom-in command and outputs a reminder message asking you to re-determine the zoom-in area.

[0049] In other embodiments, the first target area can be determined based on the area selected by the user. For example, the user can use the mouse to select the area that needs to be magnified, and then the area selected by the user is determined as the first target area.

[0050] In step 260, the corresponding position of the first target area is cropped in the first backup view to obtain the cropped second backup view.

[0051] In step 270, the second backup view is overlaid on the zoomed-in view to display the target zoomed-in area.

[0052] In this embodiment, the target magnified area displays the corresponding position information of the magnified view within the first target area. Since the second backup view is obtained by cropping the first backup view, the position information of the second backup view is the same as that of the original view in areas other than the first target area. This allows the user to zoom in on any position when in a global state, thereby improving view display efficiency.

[0053] In step 280, when a zoom-out cancellation command is received, the zoom-out effect of the zoom-out view is canceled based on the parameter information of the first backup view.

[0054] In this embodiment, based on the parameter information of the first backup view, i.e. based on the magnification factor, the position information of the magnified view is reduced so that the display effect of the position information of the magnified view is restored to the same as the display effect of the second backup view, so that the target magnified area is not displayed.

[0055] In step 290, the corresponding magnified view is displayed in the first target area to zoom in or out.

[0056] In the embodiments of this application, the magnified view and the original view have the same constraint effect. When constraining the target magnified area, corresponding constraints are also applied to the corresponding positions in the original view. Based on the target magnified area, further magnification or reduction operations can be performed to make the display effect of the target magnified area better meet the user's needs.

[0057] In step 300, when a drag command is received, the position of the second center is obtained, and the second target area is determined.

[0058] In this embodiment, the second center position can be the last position where the mouse hovers after moving away from the first center position, or it can be the position corresponding to the coordinates input by the user. The radius information of the second target area can be the same as the radius information of the first target area. In other embodiments, the radius information of the second target area can also be the position corresponding to the coordinates input by the user. It is worth noting that the second center position can be located inside or outside the second backup view.

[0059] In step 301, the target magnification area is redefined based on the second target area.

[0060] When the second center is located within the second backup view, the second target area is determined based on the position and radius information of the second center. The area corresponding to the second target area is then cropped based on the second backup view, i.e., the area corresponding to the second target area in the second backup view is removed, resulting in the removed second backup view. An intersection area is determined based on the first and second target areas; the intersection area is the area shared by both the first and second target areas. When the first and second target areas do not overlap, the intersection area is empty. Based on the intersection area, the intersection area is removed from the first target area, resulting in the removed first target area. Based on the original view information, the display of the removed first target area is restored in the removed second backup view.

[0061] When the second center is outside the second backup view, the straight line formed by the first and second centers is determined. The first center can be labeled as coordinate A, and the second center as coordinate B. A marker point is determined based on the intersection of the straight line formed by the first center A and the second center B with the boundary of the first target area; this marker point can be labeled as coordinate C. A right triangle is constructed using the straight line formed by the first center A and the second center B as the hypotenuse. A right triangle is also constructed using the straight line formed by the first center A and the marker point C as the hypotenuse. Therefore, based on the first center A, the second center B, and the radius information of the first target area, the coordinate information of the marker point C can be obtained through similar triangles. The coordinate information of the marker point can be used to display the direction in which the user's mouse leaves, making it easier for the user to move the mouse into the second backup view.

[0062] As described above, in this embodiment, when a zoom-in command is received, a first backup view is generated using the parameter information and underlying information of the original view, so that the information displayed in the first backup view is the same as that displayed in the original view. An zoomed-in view and a second backup view are generated based on the first backup view. The zoomed-in view displays the magnified effect of the position information in the first backup view, while the second backup view does not display the position information within the first target area. The second backup view is overlaid on the zoomed-in view to determine the target zoomed-in area. This means the target zoomed-in area displays the position information corresponding to the first target area in the zoomed-in view, allowing the user to view detailed position information of any zoomed-in area while maintaining the global state, greatly improving the efficiency of view display. When a drag command is received, the intersection area between the second target area and the first target area is determined based on the second target area. The intersection area within the first target area is removed to update the first target area. The updated position information of the first target area is restored and displayed on the second backup view. The second target area is then removed from the second backup view, thereby displaying the corresponding position information of the zoomed-in area on the second target area, allowing the user to quickly change the specific position of the target zoomed-in area.
