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 method for controlling a string-based slice display is provided, where the method is applied to a display screen display control software, the software is located in a server, and a user can use the display screen display control software to control a display screen to play a program.
As shown in fig. 1, the method comprises the steps of:
step S101: acquiring screen information and a to-be-displayed picture of a display screen, and displaying the to-be-displayed picture on an input interface.
Specifically, the display screen mentioned in this embodiment refers to a display screen composed of LED strings. The screen information of the display screen comprises the number of strings of the display screen, and the shape and the size of each string of the strings.
The to-be-displayed picture is displayed on an input interface (the input interface refers to an input interface in display screen display control software), and further, the to-be-displayed picture is displayed in a rectangular shape in the input interface.
More specifically, the screen information of the display screen may be input into the display control software of the display screen in advance by the user, and may be directly obtained in this step.
Step S102: and receiving a display area creating instruction, and creating N first light string display areas on the input interface, wherein N is the number of light strings in the display screen.
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 display screen display control software, namely performing click operation in an input interface of the display screen display control software.
Specifically, in an implementation manner of this embodiment, as shown in fig. 2, the method for creating N first light string display areas includes:
step S201: and generating a line segment according to the two-point clicking operation of the user.
Specifically, the user can click and select the first position point and the second position point on the input interface. After the display screen display control software acquires the first position point and the second position point selected by the user through clicking on the input interface, the first position point and the second position point can be connected into a line segment, and the line segment is generated according to the clicking operation of the user.
Wherein the second position point is a point at a different position from the first position point.
More specifically, the first location point and the second location point may be arbitrarily selected by the user on the input interface, which is not limited in the present invention. Furthermore, when the user clicks and selects the first position point and the second position point, the size of the first light string display area required to be displayed in the input interface can be determined according to the display requirements (display content requirements of the display picture, and the like), and then the first position point and the second position point are determined, so that the N first light string display areas generated according to the first position point and the second position point can be completely displayed in the input interface.
Step S202: and respectively expanding areas with the same preset length to the two sides of the line segment along the direction perpendicular to the line segment to obtain a rectangular first lamp string display area.
Specifically, as shown in fig. 3, a user clicks a point a on the input interface, then clicks a point B on the input interface, and connects A, B to form a line segment AB, and then expands the regions with the same preset length to the two sides of the line segment along the direction perpendicular to the line segment AB, so as to obtain a rectangular first light string display region, where the line segment AB is a bisector of the light string display region.
More specifically, in the present embodiment, the preset length is 0.5, that is, the width of the display area of the first string light is 1, and the length is the length of the line segment AB.
Step S203: and copying the first light string display areas according to the number of the light strings to obtain N first light string display areas.
N has already been mentioned above as the number of strings in the display.
Through the above steps S201 to S203, N first light string display areas may be created on the input interface of the display screen display control software, and it should be understood that each first light string display area corresponds to one light string on the display screen.
Step S103: and receiving a slicing instruction, and respectively slicing the picture to be displayed by utilizing each first lamp string display area to obtain N initial slicing pictures which need to be displayed in the display screen.
Specifically, in this step, after the user performs a click operation in the input interface, a slice instruction is sent to the display control software of the display screen, and after receiving the slice instruction, the display control software of the display screen slices the picture to be displayed by using each of the first light string display areas, so as to obtain N initial slice pictures to be displayed in the display screen.
More specifically, in this step, after each first light string display area is created on the input interface, the image to be displayed is sliced by using the first light string display area according to the received slicing instruction, until all N first light string display areas are created, N initial slice images are obtained.
After all N first light string display areas are created on the input interface, each first light string display area is utilized to slice the picture to be displayed according to the received slicing instruction, and N initial slice pictures are obtained.
Further, in an implementation manner, before slicing the to-be-displayed picture by using each first light string display area, a user needs to perform a click operation on an input interface, and the display screen display control software respectively adjusts each first light string display area according to the click operation of the user, so that when the to-be-displayed picture is sliced by using each first light string display area, an obtained initial slice picture is a picture that needs to be displayed in the display screen. Specifically, the adjusting includes at least one of rotating, translating, zooming, and point editing.
Wherein, the point editing is to adjust the position of a certain vertex of the first light string display area (in the first light string display area of the invention, 4 vertexes can be point edited); the rotation is performed by taking the central point of the first light string display area as a rotation center, a straight line can be led out from the central point, the default starting angle is 0 degree or 360 degrees, and the second light string display area is rotated by a corresponding angle; zooming refers to zooming the first string display area in the length and width directions.
More specifically, a user may first click and trigger a dragging adjustment instruction on an input interface, drag a first light string display area to be adjusted, translate the first light string display area (the user performs dragging operation on the input interface, and display screen display control software adjusts the position of the first light string display area according to the dragging adjustment instruction of the user to make the first light string display area translate on the input interface), move the first light string display area to a to-be-displayed picture on the input interface, and then click and trigger a zoom, rotate, and point edit adjustment instruction (the display screen display control software zooms and rotates the first light string display area and changes the position of a light string vertex according to the zoom, rotate, and point edit adjustment instruction) to make the picture content of the to-be-displayed picture in the first light string display area be the picture content to be displayed on the display screen (for example, the picture content of a picture to be displayed in the display screen is changed by clicking and triggering the first light string display area to adjust the position of the first light string display area to be adjusted The user can observe conveniently, the outer frame of the area of each first lamp string display area is a colored frame, the inner part of the area is in a transparent state, and the picture to be displayed below can be shown). In other embodiments, the adjustment method of the first light string display area may be determined directly or by directly using one or more adjustment manners of zooming, rotating, and point editing without performing translation, specifically according to the display content requirement of the display screen.
After the above process, the user triggers the slicing instruction on the input interface, so that the display screen display control software cuts the current picture content in the first light string display area from the complete picture to be displayed after receiving the slicing instruction, so as to obtain the initial slicing picture to be displayed in the display screen.
Step S104: and displaying each initial slice picture in a second light string display area corresponding to the initial slice picture.
Specifically, the second light string display areas in this step are located on an output interface of the display control software of the display screen, the number of the second light string display areas is N, and each second light string display area corresponds to one first light string display area and further corresponds to one light string on the display screen.
More 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, so that according to the position coordinates of each first light string display area on the input interface, a second light string display area corresponding to the first light string display area can be created on the output interface.
The second light string display area corresponding to the first light string display area refers to that the position of the second light string display area in the output interface corresponds to the position of the first light string display area in the input interface, the shapes of the second light string display area and the first light string display area are the same, the size proportion of the second light string display area and the first light string display area is the same, and the two areas are in vertex correspondence.
Because N initial slice pictures are obtained by slicing the picture to be displayed by utilizing N first light string display areas on the input interface, each initial slice picture has a first light string display area corresponding to the initial slice picture, and each first light string display area corresponds to a second light string display area, so that each initial slice picture has a second light string display area corresponding to the initial slice picture.
Step S105: and adjusting each second light string display area according to the screen information so as to adjust the initial slice image in the second light string display area into a target slice image corresponding to the display screen.
Specifically, in this step, the shape and size of each second light string display area may be proportionally adjusted according to screen information (the number of light strings, the shape and size of each light string) of the display screen, so that the shape of the second light string display area is adjusted to be the same as the light string corresponding to the second light string display area in the display screen, and the size of the second light string display area is adjusted to be corresponding to the light string corresponding to the second light string display area in the display screen (including the length proportion of each frame is the same), at this time, the initial slice image displayed in the second light string display area is adjusted accordingly, so that the initial slice image is adjusted to be the target slice image corresponding to the display screen, and specifically, the initial slice image is adjusted to be the target slice image corresponding to the light string corresponding to the second light string display area in the display screen.
It should be noted that the adjustment of the second light string display area in the output interface does not affect the first light string display area of the input interface, that is, the shape, size and position of the first light string display area are not changed.
During actual adjustment, the shape and size of the second light string display area may be proportionally adjusted to make the shape and length ratio of each frame of the second light string display area the same as the light string corresponding to the second light string display area in the display screen (i.e. the shape and the size are the same), and specifically, at least one adjustment mode of translation, rotation, scaling and point editing may be adopted to make the shape and length ratio of each frame of the second light string display area the same as the light string corresponding to the second light string display area in the display screen. Similarly, point editing herein refers to adjusting one or more vertex coordinates of the second string display area. Furthermore, in this step, when zooming the second light string display area, it means zooming the second light string display area in the length direction and the width direction, and the width is kept unchanged; when the second light string display area is rotated, the second light string display area can be rotated by taking the central point of the second light string display area as a rotation center, furthermore, a straight line can be led out from the central point, the default starting angle is 0 degree or 360 degrees, and the second light string display area is rotated by a corresponding angle. Of course, it should be understood that when the second string light display area is rotated in the present invention, other points on the output interface may also be used as the rotation center for rotation, and the above mentioned rotation manner is not a limitation to the present invention.
It should be noted that, in this step, when the second light string display area is adjusted according to the screen information, the second light string display area is kept horizontally and forwardly placed on the output interface (as shown in fig. 9), the placing angle of the second light string display area does not need to be adjusted according to the placing angle of the light string corresponding to the second light string display area in the display screen (the light string may be obliquely placed), and only the shape and size of the second light string display area are adjusted, so that the shape of each second light string display area is the same as the shape and size of the light string corresponding to the second light string display area in the display screen (i.e., the size ratio is the same — the length ratio of each frame is the same).
Furthermore, when the adjustment is performed, the second light string display area is adjusted in the output interface according to a line form, specifically because the display screen performs point tracing according to a line form, in order to avoid the problem that the adjustment efficiency is affected by the fact that the position of each light point in the whole light string needs to be calculated when the light strings are placed obliquely, the second light string display area is not adjusted according to the actual placing position and angle of the light strings in the display screen, but is adjusted to be placed in the horizontal forward direction in the output interface, and then the shape and the size of the second light string display area are adjusted in the output interface according to a line form.
More specifically, in this step, each second light string 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 light string display area, or display control software may automatically adjust each second light string display area according to the screen information (identify a position point corresponding to each light string in the CAD picture of the display screen), which is not limited in this embodiment.
In this embodiment, by obtaining screen information of the display screen and a to-be-displayed picture, a line segment is generated according to a two-point click operation of a user, and then a preset length is extended to two sides of the line segment in a direction perpendicular to the line segment, so that a rectangular first light string display area is obtained, and the first light string display area is copied, so that N first light string display areas are obtained. The whole process of creating the first light string display area can be completed only by clicking two position points on the input interface by a user, so that the creating efficiency of the first light string display area is improved. Subsequently, the N first light string display areas are utilized to slice the picture to be displayed to obtain N initial slice pictures, each initial slice picture is displayed in the corresponding second light string display area, the second light string display area is adjusted according to screen information, the initial slice pictures in the second light string display area are adjusted to be target slice pictures corresponding to the display screen, the N first light string display areas are quickly established on the input interface to slice the picture to be displayed, the corresponding N target slice pictures are quickly obtained on the output interface, and therefore a user can obtain the playing effect on the display screen by observing the target slice pictures on the output interface and further adjust the playing effect.
The method provided by the invention greatly improves the efficiency of creating the first light string display area, improves the slicing efficiency of the picture to be displayed, can accurately display the initial sliced picture into the second light string display area, and then adjusts the second light string display area to obtain the target sliced picture, improves the efficiency of obtaining the target sliced picture on the output interface, and further improves the adjustment efficiency of adjusting the picture content on the user output interface.
In another embodiment of the present invention, a CAD picture of the display screen may be input by a user in advance, where the CAD picture displays the number of strings in the display screen, the actual placement condition (e.g., actual placement angle, placement position, etc.) of each string, and the shape and size of each string.
In this case, as shown in fig. 4, before step S101, the method further includes:
step S106: and determining the screen information of the display screen according to the input CAD picture of the display screen.
Specifically, the CAD coordinates of the light string display screen are determined through the CAD picture of the display screen input by the user, and the screen information of the display screen is further determined according to the CAD coordinates of the display screen.
