Detailed Description
The following detailed description of the disclosed embodiments will be made in conjunction with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flowchart illustrating a signal layer adjustment method according to an exemplary embodiment, where the method includes:
in step 101, the number of reference lines and the corresponding position of each reference line in the display interface are determined.
The reference line is used for moving a signal layer displayed on a display interface.
In an example, the reference line is used for locking an edge of a signal layer in a display interface and driving the locked edge to move on the display interface, so that the position of the signal layer is moved or the signal layer is extended or shortened. Therefore, before adjusting the signal layer through the reference line, the number and the position of the reference line in the display interface need to be determined. At present, the position of the reference line is usually represented by coordinate values in a display interface coordinate system, for example, after coordinate values of a center point and two end points of the reference line are respectively determined, the position of the reference line is determined, and information such as the length of the reference line and a parallel relationship with a horizontal side or a vertical side of the display interface (in general, the form of the reference line is only parallel to the horizontal side or parallel to the vertical side of the display interface) is also obtained.
In step 102, the number of reference lines and corresponding edges locked with each signal layer are determined according to the position of each reference line.
Wherein each edge of the signal layer is locked with at most one reference line.
Illustratively, edges in the signal layers that are locked to the reference line are determined based on the positions of the reference line and the signal layers. In the embodiment of the present disclosure, identification information, for example, numbers 1, 2, 3, and the like, is set for each reference line, and after one of the reference lines is locked with one edge of the signal layer, the edge corresponds to the identification information (for example, number 3) of the locked reference line, and the edge without the locked reference line corresponds to number 0.
It is understood that when an edge without a locked reference line is locked with a reference line, the number corresponding to the edge is automatically converted from "0" to the identification information (e.g., number 3) of the locked reference line.
In step 103, a preset number of first target signal layers to be moved are determined.
And only one of two parallel edges of each first target signal layer is locked with the same first target reference line.
For example, when an image displayed on the LED screen needs to be moved (for example, an image displayed on the left side of the screen needs to be moved to a position in the middle of the screen), a signal layer corresponding to the image needing to be moved is determined, and the signal layer is moved so that the corresponding image is moved by the same distance. It should be noted that, in the embodiments disclosed in the present invention, batch movement of the display images on the LED screen may be implemented by moving the same reference line locked with multiple signal layers. Therefore, among the plurality of signal layers which need to be moved in the same direction, a preset number of first target signal layers, which are locked with the same first target reference line and only one of two parallel sides, are determined.
It can be understood that, when the edge of the first target signal layer locked with the first target reference line is perpendicular to the moving direction, the first target signal layer is driven to move by a corresponding distance along the same direction by moving the first target reference line along the perpendicular direction.
In step 104, if a moving instruction for moving the preset number of first target signal layers along a direction perpendicular to the first target reference line is received, the first target reference line is moved according to the moving distance and the moving direction indicated in the moving instruction, so as to drive the preset number of first target signal layers to move to the specified position.
Illustratively, the signal layer is locked with the reference line, which includes the following conditions: (1) only one of two parallel sides of the signal layer is locked with the same reference line; (2) only one of two vertically parallel edges of the signal layer is locked with the same reference line; (3) two parallel edges at the left and right of the signal layer are respectively locked with the same two reference lines; (4) two parallel edges of the signal layer are locked with the same two reference lines respectively. For the case (1), if only one of the two sides of the signal layer parallel to the left and right is locked to the same entry reference line, no matter whether there is a side locked to another reference line in the two sides of the signal layer parallel to the top and bottom, the reference line locked to one of the two sides of the signal layer parallel to the left and right may be moved to drive the signal layer to move by the same distance in the direction perpendicular to the reference line (case (2) is the same as above). Therefore, when the first target reference line is locked with a preset number of first target reference layers, if a moving instruction for moving the first target signal layer along a direction perpendicular to the first target reference line is received, moving the first target reference line can drive the first target signal layer to correspondingly move. Therefore, in the process of splicing the signal layers, if the plurality of signal layers need to be moved simultaneously, the plurality of first target signal layers can be moved in batches by selecting the plurality of first target signal layers in the mode in the step 104, and the problems of low moving efficiency, deviation of moving distance and direction and the like in manual moving of the signal layers are solved.
It will be appreciated that in the display interface coordinate system (computer coordinate system), the coordinates of the 4 vertices of the signal layer are obtained, for example, (x)1,y1)，(x2,y2)，(x3,y3)，(x4,y4) I.e. the position and size of the signal layer is determined. If a moving instruction for moving a signal layer downwards by 5 unit lengths is received (namely, a downward offset of 5 is obtained), a reference line locked with the signal layer is moved downwards by 5 unit lengths, and the coordinates of 4 vertexes of the signal layer become (x)1,y1-5)，(x2,y2-5)，(x3,y3-5)，(x4,y4-5), the size is unchanged.
Fig. 2 is a flow chart of another method for adjusting signal layers according to fig. 1, and as shown in fig. 2, the method further includes: step 105-step 106;
in step 105, a preset number of second target signal layers to be stretched/shortened is determined.
And two parallel edges of each second target signal layer are respectively locked with two same second target reference lines.
For example, when the image displayed on the LED screen needs to be adjusted to be extended or shortened, a signal layer corresponding to the image that needs to be extended or contracted is determined, and the signal layer is extended or contracted by the same distance as the corresponding image. It should be noted that, in the embodiments disclosed in the present invention, batch movement of the display images on the LED screen may be implemented by moving the same reference line locked with multiple signal layers. Therefore, among the plurality of signal layers which need to be moved in the same direction, a preset number of first target signal layers, which are locked with the same first target reference line and only one of two parallel sides, are determined.
In step 106, if an extending/shortening instruction for extending/shortening the preset number of second target signal layers is received, one of the second target reference lines is moved according to the extending/shortening distance indicated in the extending/shortening instruction, and the other second target reference line fixes the locked edge at the original position on the display interface, so as to drive the preset number of second target signal layers to extend/shorten the preset distance.
For example, for the case (3) in the step 104, if two sides parallel to the left and right of the signal layer are respectively locked with the same two reference lines, at this time, no matter whether there is a side locked with another reference line in the two sides parallel to the top and bottom of the signal layer, the reference line locked with one side in the two sides parallel to the top and bottom of the signal layer may be moved to drive the stretching of the signal layer (case (4) is the same as the above). Therefore, when the second target signal layer and the second target reference line are determined, one of the two second target reference lines functions as a fixed locking edge, and the other second target reference line functions as a moving locking edge, so that moving the second target reference line can function to extend or shorten the signal layer. When two second target reference lines are locked with a preset number of second target reference layers, if an extending/shortening instruction for extending/shortening the preset number of second target signal layers is received, moving a locked edge through one second target reference line, and fixing another locked edge through another second target reference line so as to extend/shorten the preset number of second target signal layers.
It is understood that, if a shortening instruction to shorten a signal layer by 5 unit lengths is received, the reference line locked with the upper side of the signal layer is moved downward by 5 unit lengths, the reference line locked with the lower side of the signal layer fixes the lower side of the signal layer, and the coordinates of the 4 vertices of the signal layer become (x) to1,y1-5)，(x2,y2-5)，(x3,y3)，(x4,y4) The size changes.
Fig. 3 is a flow chart of a reference line locking method according to fig. 1, and as shown in fig. 3, the step 102 includes:
in step 1021, if one edge of the signal layer does not coincide with the reference line, a reference line parallel to the edge and spaced apart from the edge by a distance less than a preset distance threshold exists in the display interface, and the signal layer is extended until one edge coincides with the reference line.
In step 1022, the reference line coinciding with each edge in the signal layer is determined as the edge-locked reference line coinciding with the signal layer.
Exemplarily, if an edge coinciding with the reference line exists in the signal layer, locking the edge with the coinciding reference line; if one side in the signal layer is not overlapped with the reference line, whether a reference line which is parallel to the side and is separated by a distance smaller than a preset distance threshold exists in the display interface or not is judged, if yes, the signal layer is extended along the direction vertical to the reference line until the side, closest to the reference line, of the signal layer is overlapped with the reference line, and at the moment, the side of the signal layer is locked with the overlapped reference line. In this way, the reference lines locked to each edge of each signal layer (i.e. the number of reference lines locked to each signal layer) and the position of the reference lines can be determined.
It will be appreciated that when there is a reference line that is not coincident with an edge of a signal layer and is spaced apart by a distance less than a predetermined distance threshold, extending the edge until it coincides with the reference line enables the signal layer to be adaptively filled in accordance with the reference line.
Fig. 4 is a flow chart of a reference line determination method according to fig. 1, as shown in fig. 4, the step 101 includes:
in step 1011, the position of each signal layer in the display interface is determined.
In step 1022, the number of reference lines and the position of each reference line are determined according to the size of each signal layer and the position of the signal layer on the display interface.
For example, as shown in step 103, the positions of the signal layers are represented by coordinate values of 4 vertices of the signal layers in the coordinate system of the display interface, and therefore, after the positions of the signal layers are determined, the number of reference lines in the display interface and the position of each reference line are determined according to a preset reference line determination policy.
By way of example, the reference line determination policy may be: the number of reference lines and the position of each reference line in a preset range around each signal layer are determined according to the size and the position of each signal layer on a display interface, and meanwhile, the number and the position of the reference lines can be adjusted according to image content corresponding to the signal layers.
Fig. 5 is a flowchart of an image layer triggering method shown in fig. 1, where as shown in fig. 5, the method further includes:
in step 501, a trigger instruction indicating that the third target signal layer is enlarged to fill the display interface is received.
In step 502, according to the trigger instruction, the third target signal layer is enlarged to fill the display interface within a preset time period.
For example, when a preset trigger instruction is received by a third target signal layer (for example, a touch screen operation or a mouse pointer staying time reaches a preset time threshold), the third target signal layer is enlarged to fill the whole display interface (i.e., full-screen display) according to the trigger instruction, full-screen display is performed on the third target signal layer within a preset time period, and then the third target signal layer is reduced and restored to an initial position. Therefore, when the image in one signal layer needs to be magnified and viewed, the image displayed in the signal layer is displayed in a full screen mode, and the observation is convenient for workers.
