Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In an embodiment of the present invention, a slice display control method based on a sector is provided, where the method is applied to a sector display screen display control software of an upper computer, the software is located in a server, and a user can control a sector display screen to play a program by using the sector display screen display control software.
As shown in fig. 1, the method comprises the steps of:
step S101: acquiring screen information and a to-be-displayed picture of the fan-shaped display screen, and displaying the to-be-displayed picture on an input interface.
Specifically, the fan-shaped display screen mentioned in this embodiment is a flat display screen, which refers to a flat LED display screen with a fan-shaped screen. The screen information of the fan-shaped display screen comprises the actual placement condition, the screen shape and the size of the fan-shaped display screen.
The frame to be displayed is displayed on an input interface (the input interface refers to an input interface in upper computer fan-shaped display screen display control software), and further, the frame to be displayed is displayed in a rectangular shape in the input interface.
More specifically, the screen information of the fan-shaped display screen can be input into the fan-shaped display screen display control software of the upper computer in advance by a user and can be directly acquired in the step.
Step S102: and receiving a display area creating instruction, and creating a first fan-shaped display area on the input interface.
The display area creating instruction is triggered by a user, and the user triggers the display area creating instruction through a function of performing trigger point editing on the upper computer software, namely performing click operation in an input interface of the upper computer software.
Specifically, in an implementation manner of this embodiment, as shown in fig. 3, the method for creating the first fan-shaped display area in step S102 includes:
step S301: an elliptical region is created.
Specifically, the ellipse mentioned in this step includes a circle.
Step S302: and leading out a starting line segment and a terminating line segment from the center point of the elliptical area, determining a sector surrounded by the starting line segment, the terminating line segment and the frame of the elliptical area as a first sector display area, and displaying the first sector display area on an input interface.
Specifically, in this step, a user may perform a click operation on the input interface, as shown in fig. 4, an initial endpoint P and a termination endpoint S are selected by clicking on the outside of the elliptical area or the outer frame of the elliptical area, and after receiving the click operation of the user, the upper computer software introduces a start line segment OP (two endpoints of the start line segment are respectively the start endpoint and the center point of the elliptical area) and a termination line segment OS (two endpoints of the termination line segment are respectively the termination endpoint and the center point of the elliptical area) from the center point O of the elliptical area. Of course, an initial endpoint P and a termination endpoint S may also be directly and automatically set by the upper computer software outside the elliptical area or on the outer frame of the elliptical area, and then a starting line segment OP (the two endpoints of the starting line segment are respectively the starting endpoint and the center point of the elliptical area) and a terminating line segment OS (the two endpoints of the terminating line segment are respectively the termination endpoint and the center point of the elliptical area) are led out from the center point O of the elliptical area, and then the user finally adjusts the starting line segment OP and the terminating line segment OS, more specifically, the included angle between the starting line segment OP and the terminating line segment OS (the fan-shaped included angle of the first fan-shaped display area) is changed by adjusting the position coordinates of the initial endpoint P on the starting line segment and the termination endpoint S on the terminating line segment.
Further, a straight line may be drawn from a center point of the elliptical area, an angle corresponding to the straight line is set to be 0 degree or 360 degrees by default, a start angle (the start angle is an angle corresponding to the start line segment OP) and an end angle (the end angle is an angle corresponding to the end line segment OS) are determined in a clockwise (counterclockwise) manner through an initial end point P and an end point S selected by a user or upper computer software, and a sector area sandwiched between the start angle (the start line segment) and the end angle (the end line segment) in the clockwise (counterclockwise) direction is used as a first sector display area.
For example, in fig. 4, in the clockwise direction, the start angle is determined first, then the end angle is determined (the start line segment is determined first, then the end line segment is determined), and a sector area (a shaded portion in fig. 4) formed between the start line segment and the end line segment in the clockwise direction is taken as the first sector display area.
Step S103: and receiving a slicing instruction, and slicing the picture to be displayed by utilizing the first fan-shaped display area to obtain an initial slice picture to be displayed in the fan-shaped display screen.
Specifically, before slicing, a user needs to adjust (including rotation, translation, zooming, and point editing) a first fan-shaped display area on an input interface so that a picture sliced from the first fan-shaped display area is an initial slice picture that needs to be displayed on a fan-shaped display screen, where the point editing is to adjust a position of a vertex of the first fan-shaped display area.
More specifically, a user may first trigger a dragging adjustment instruction on an input interface by clicking, and then move the first fan-shaped display area by dragging the first fan-shaped display area (the user performs dragging operation on the input interface, and the upper computer software adjusts the position of the first fan-shaped display area according to the dragging adjustment instruction of the user to make the first fan-shaped display area move on the input interface), and then move the first fan-shaped display area to a to-be-displayed picture on the input interface, and then trigger a zooming, rotating, and point editing adjustment instruction by clicking (the upper computer software performs zooming and rotating on the first fan-shaped display area and changes the position of a certain vertex according to the zooming, rotating adjustment, and point editing instruction), so that the picture content of the to-be-displayed picture in the first fan-shaped display area is the picture content that needs to be displayed in the fan-shaped display screen (for the convenience of user observation, the outer frame of the first sector display area is a colored frame, and the inside of the area is in a transparent state, so that a picture to be displayed below the area can be shown).
After the above process, the user triggers a slicing instruction on the input interface, so that after the upper computer software receives the slicing instruction, the current picture content in the first fan-shaped display area is cut from the complete picture to be displayed, so as to obtain an initial slicing picture to be displayed in the fan-shaped display screen.
Step S104: and displaying the initial slice picture into a second fan-shaped display area corresponding to the first fan-shaped display area, wherein the second fan-shaped display area is positioned on an output interface.
Specifically, a coordinate mapping relationship exists between coordinate points on the input interface and coordinate points on the output interface in a one-to-one correspondence manner, that is, each coordinate point on the input interface can find a corresponding coordinate point in the output interface.
The second fan-shaped display area corresponding to the first fan-shaped display area refers to that the position of the second fan-shaped display area in the output interface corresponds to the position of the first fan-shaped display area in the input interface, the shapes of the second fan-shaped display area are the same, the size proportion of the second fan-shaped display area is the same, and the second fan-shaped display area and the first fan-shaped display area are in vertex correspondence.
Step S105: and adjusting the second fan-shaped display area according to the screen information so as to adjust the initial slice image in the second fan-shaped display area to a target slice image corresponding to the fan-shaped display screen.
Specifically, in this step, the shape and size of the second sector display area may be proportionally adjusted according to the screen information (shape and size) of the sector display screen, so that the shape of the second sector display area is adjusted to be the same as the sector display screen (including adjusting the included angle between the start line segment and the end line segment in the second sector display area to be equal to the included angle of the sector display screen), and the size of the second sector display area is adjusted to be corresponding to the sector display screen (including the length proportion of each frame to be the same as the sector display screen), at this time, the initial slice image displayed in the second sector display area is adjusted accordingly, so that the initial slice image is adjusted to be the target slice image corresponding to the sector display screen. It should be noted that the adjustment of the second fan-shaped display area does not affect the first fan-shaped display area of the input interface, that is, the shape, size and position of the first fan-shaped display area are not changed.
Further, in this step, the second fan-shaped display area corresponds to the fan-shaped display screen, and in addition to the above-mentioned shape and size, the second fan-shaped display area is also placed (placed angle) in the same manner as the fan-shaped display screen.
During actual adjustment, the shape and the size of the second fan-shaped display area can be adjusted in proportion, so that the shape and the length proportion of each frame of the second fan-shaped display area are the same as those of the fan-shaped display screen (namely, the shape is the same, and the size is corresponding), the placing condition of the second fan-shaped display area is adjusted (placing angle), and the modes of translation, rotation, scaling and point editing can be specifically adopted, so that the placing condition of the second fan-shaped display area is consistent with the actual placing condition of the fan-shaped display screen, and the length proportion of each frame of the second fan-shaped display area is the same as that of the fan-shaped display screen. Similarly, the point editing herein refers to adjusting one or more vertex coordinates of the second fan-shaped display region.
It should be understood that, when the above adjustment is performed on the second fan-shaped display area, after the included angle between the start line segment and the end line segment is adjusted to be equal to the included angle of the fan-shaped display screen, and then rotation, translation, zooming and other adjustments are performed, the included angle between the start line segment and the end line segment does not change any more, that is, the positions of the start endpoint and the end endpoint are not adjusted accordingly. So as to ensure that the fan-shaped included angle of the second fan-shaped display area is always equal to the fan-shaped included angle of the fan-shaped display screen.
More specifically, in this step, the second sector display area is adjusted according to the screen information, and a user may trigger an adjustment instruction on the output interface according to the screen information, so as to manually control the adjustment of the second sector display area, or the upper computer software may automatically adjust the second sector display area according to the screen information (identify a position point corresponding to the screen information in the CAD drawing), which is not limited in this embodiment of the present invention.
In the embodiment, an oval area is firstly created by acquiring screen information of a fan-shaped display screen and a picture to be displayed; determining a first fan-shaped display area from the elliptical area; slicing a picture to be displayed by utilizing the first fan-shaped display area to obtain an initial slice picture; the method comprises the steps of displaying an initial slice picture to a second fan-shaped display area corresponding to a first fan-shaped display area, adjusting the second fan-shaped display area according to screen information, adjusting the initial slice picture in the second fan-shaped display area to a target slice picture corresponding to a fan-shaped display screen, quickly creating the first fan-shaped display area on an input interface to slice a picture to be displayed in the whole process without copying and splicing, and quickly obtaining a target slice picture on an output interface, so that a user can obtain a playing effect on the fan-shaped display screen by observing the target slice picture on the output interface, and further adjust the playing effect.
The method provided by the invention greatly improves the efficiency of creating the first fan-shaped display area, improves the slicing efficiency of the picture to be displayed, can accurately display the initial slice picture into the second fan-shaped display area, and then adjusts the second fan-shaped display area to obtain the target slice picture, improves the efficiency of obtaining the target slice picture on the output interface, and further improves the adjustment efficiency of adjusting the picture content on the user output interface.
In still another embodiment of the present invention, a CAD picture of the fan-shaped display screen may be input by the user in advance, and the actual placement condition (for example, the actual placement angle, etc.) of the fan-shaped display screen and the shape and size of the fan-shaped display screen are displayed in the CAD picture.
In this case, as shown in fig. 2, before step S101, the method further comprises:
step S106: and determining the screen information of the fan-shaped display screen according to the input CAD picture of the fan-shaped display screen.
Specifically, the CAD coordinates of the sector display screen are determined through the CAD picture of the sector display screen input by the user, and the screen information (placement, shape, size) of the sector display screen is further determined according to the CAD coordinates of the sector display screen.
In another embodiment of the present invention, there is a one-to-one coordinate mapping relationship between coordinate points on the input interface and coordinate points on the output interface, and after a first fan-shaped display area is created on the input interface, the method further includes:
and identifying the coordinate point of the first fan-shaped display area on the input interface in real time, and generating a second fan-shaped display area at the corresponding position of the output interface according to the coordinate mapping relation. That is, when the position of the first fan-shaped display area on the input interface is changed due to the user performing adjustment such as translation, rotation, and zooming on the first fan-shaped display area on the input interface, the position of the second fan-shaped display area on the output interface is simultaneously adjusted accordingly.
After the user finishes the adjustment to first fan-shaped display area, trigger the section instruction, first fan-shaped display area position no longer changes, and host computer software utilizes first fan-shaped display area to treat the display frame and cuts a slice, after obtaining initial slice picture, with initial slice picture display to with first fan-shaped display area correspond the second fan-shaped display area including: and identifying a coordinate point of the initial slice on the input interface, and displaying the initial slice in a second fan-shaped display area (the position of the second fan-shaped display area corresponds to the position of the first fan-shaped display area during slicing) according to the coordinate mapping relation.
Further, a coordinate system may be established on the input interface (with the uppermost side as the positive half axis of the X axis and the leftmost side as the positive half axis of the Y axis), position coordinates of all points of the input interface are obtained, all the position coordinates are stored in an array form (each position coordinate corresponds to a subscript, for example, (0,0) corresponds to 0), and after a user clicks a certain position point on the input interface, a specific click position is determined from the stored array through the corresponding coordinate or subscript of the position point. In the output interface, a coordinate system is created in the same manner as described above, position coordinates of all points of the output interface are obtained, and all the position coordinates are stored in an array form (each position coordinate corresponds to a subscript, for example, (0,0) corresponds to 0). The subscripts of the input interface and the output interface are consistent, that is, each position point of the input interface corresponds to each position point of the output interface, so that a coordinate mapping relation exists between the coordinate points on the input interface and the coordinate points on the output interface in a one-to-one correspondence manner.
Further, a one-to-one mapping coordinate correspondence relationship between coordinate points of the partial region in the input interface and the partial region in the output interface may be set. In the input interface, a target rectangular area associated with the material may be set (the width and height of the target rectangular area may be arbitrarily adjusted, and it is understood that the target rectangular area of the input interface is actually a display window of a picture to be displayed), a coordinate system is established in the target rectangular area (the uppermost edge is taken as an positive half axis of an X axis, and the leftmost edge is taken as a positive half axis of a Y axis), position coordinates of all points of the target rectangular area are obtained, all the position coordinates are stored in an array form (each position coordinate corresponds to a subscript, such as (0,0) corresponds to 0), and after a user clicks a certain position point on the input interface, a specific click position is determined from the stored array through the coordinate or subscript corresponding to the position point; and in the output interface, setting a target rectangular area corresponding to the size of the actual display screen, creating a coordinate system according to the same manner to obtain the position coordinates of all points of the target rectangular area, and storing all the position coordinates in an array form (each position coordinate corresponds to a subscript, such as (0,0) corresponds to 0). The target rectangular area of the input interface is used for displaying a picture to be displayed, and the target display area of the output interface is used for displaying a slice picture. Subscripts in the target rectangular region of the input interface and the target rectangular region of the output interface are consistent, that is, each position point of the input interface corresponds to each position point of the output interface, so that a coordinate mapping relationship exists between coordinate points on the target rectangular region of the input interface and coordinate points on the target rectangular region of the output interface.
In yet another embodiment of the present invention, as shown in FIG. 5, creating an elliptical region comprises the steps of:
step S501: and creating a first rectangular area on the input interface, and receiving a first initial point selected by a user clicking on a frame of the first rectangular area, wherein the first initial point and the center point of the first rectangular area are positioned on the same horizontal line.
It should be understood that the step of defining a first rectangular area refers to defining the first rectangular area on the input interface.
