Background

In the related art, an electronic map may express geospatial data through a vector data model. Vector data models typically express geospatial entity location and extent in the real world by elements such as points, lines, and facets. Wherein the line may include a solid line or a dotted line according to the type of the line. Different geographical information may be expressed according to different lineages, e.g. a line may be used to represent a road or a boundary.

In an electronic map, a boundary line such as a province boundary line or a national boundary line is often indicated by a dotted line. Generally, at the PC side of a computer, a system of the computer itself may support OpenGL (Open Graphics Library, "open graphics library" or "open graphics library") to draw a dotted line in an electronic map. Wherein OpenGL is a cross-language, cross-platform application programming interface for rendering 2D, 3D vector graphics. Efficient implementations of OpenGL (using graphics acceleration hardware) exist in Windows, part of the UNIX platform, and Mac OS. These implementations are typically provided by the display device vendor and are highly dependent on the hardware provided by the vendor. For the vehicle-mounted intelligent device, the system is generally an embedded system, which cannot support OpenGL to draw a dotted line and needs manual drawing, so that the workload is increased.

In the related art, a terminal with low hardware configuration, such as a vehicle-mounted intelligent device, a mobile phone, and the like, cannot automatically draw a dotted line in an electronic map by using OpenGL, and needs to be manually drawn, so that the workload is increased. Aiming at the problems, the embodiment of the application provides a method for generating the dotted line texture, which can quickly generate the dotted line texture on the electronic map and improve the working efficiency. The following describes the technical scheme of the embodiment of the present application in detail with reference to the accompanying drawings.

Example 1

Fig. 1 is a flowchart of a method for generating a dashed texture according to an embodiment of the present application.

Referring to fig. 1, the method for generating the dotted texture includes:

step S110, coloring the target pixel point in the picture to be processed according to the preset color to form a dotted line symbol.

It will be appreciated that a picture is made up of at least one target pixel having a location and a color. The picture to be processed comprises at least one target pixel point. In this embodiment, the image to be processed includes a plurality of target pixel points. In an electronic map, different geographic elements can be generally distinguished by different colors. For example, water areas in geographic elements are shown in blue and mountain forests are shown in green. In one embodiment, at least one preset color may be used to color the target pixel point in the image to be processed, so as to form a dotted line symbol. The target pixel point is a pixel point to be colored. That is, the colored picture to be processed includes at least one color, i.e., the single dashed symbol includes at least one color. In one embodiment, the dashed symbols are any one of a line structure, a dot structure, or an alternating structure of lines and dots. Further, the size of a single dotted symbol may be achieved by coloring the target pixel dots by a preset number. For example, for a dashed symbol of a short-line structure, the line and line width of a single short line can be adjusted by controlling the number of colored target pixel points.

In other embodiments, the method of the present application is not limited to forming a pattern with a dotted line symbol by coloring a target pixel point of a picture to be processed, but also forming a pattern with any other shape by coloring, and has a high flexible operability.

Step S120, screen position information of the boundary line to be marked on the electronic map is obtained, and the display quantity of the dotted line symbols is calculated.

The electronic map is displayed on a display screen of the terminal, and when a certain position of the current map interface needs to be displayed with a broken line, for example, a provincial line of the current map interface needs to be displayed with the broken line, and the provincial line is the boundary to be marked. By acquiring the screen position information of the boundary line to be marked, the number of the dotted symbols to be displayed can be calculated so that a sufficient and proper number of the dotted symbols are continuously displayed at the position of the screen of the boundary line to be marked.

Step S130, according to the display number of the dotted symbols and the screen position information of the boundary line to be marked, the dotted textures are displayed at the corresponding positions of the electronic map after each dotted symbol is spliced in sequence.

It can be understood that, on the display screen, the position to be displayed of the texture of the dotted line can be defined by the screen position information of the boundary line to be marked; and the corresponding number of the colored dotted symbols can be spliced one by one in sequence at the position to be displayed through calculating the display number of the colored dotted symbols, so that the dotted textures are formed. The method for generating the dotted line texture forms the dotted line texture by coloring the target pixel point in the picture to be processed to form the dotted line symbol and displaying a certain number of the dotted line symbols on the electronic map according to the screen position information of the boundary line to be marked. On one hand, the picture is easier to configure the colors and is more flexible to operate; meanwhile, the display position of the dotted line texture on the screen is determined directly according to the screen position information of the boundary line to be marked in the electronic map displayed on the current screen, so that the operation amount is small, the display is fast, and the display efficiency is improved. On the other hand, the method has the advantages that drawing is not needed, the data point sequence of the electronic map is not needed to be changed, the dotted line textures are directly displayed on the upper layer of the electronic map in the form of pictures, the requirement on hardware is low, and the use requirement of hardware such as vehicle-mounted intelligent equipment or mobile phones is met.

In one embodiment, the steps S110 and S120 of the present application may be performed in no sequential order, i.e., the steps S110 and S120 may be performed simultaneously or in steps in any order.

Example two

Fig. 2 is another flow chart of a method for generating a texture with a broken line according to an embodiment of the present application.

Referring to fig. 2, the method for generating the dotted texture includes:

step S210, according to the preset color, performing colored coloring on part of the target pixel points in the picture to be processed, and performing transparent coloring on the other part of the target pixel points to form a dotted line symbol.

In one embodiment, according to a preset color, a part of target pixel points in a picture to be processed are colored to form colored target pixel points; transparent coloring is carried out on the other part of the target pixel points to form transparent target pixel points; the colored target pixel points and the transparent target pixel points form a dotted line symbol. That is, the dotted line symbol is formed by colored target pixel points and transparent target pixel points in a preset order. Further, the dotted line symbol may be any one of a line structure, a dot structure, or an alternating structure of lines and dots. And at least one colored target pixel point and at least one transparent target pixel point sequentially form a dotted line symbol according to preset positions. When the dotted line symbol is a line structure, the colored target pixel points are sequentially spliced to form lines, and the transparent target pixel points are sequentially spliced to form intervals between adjacent lines, namely the dotted line symbol of the single line structure consists of colored lines and transparent intervals. Similarly, for the broken line symbols of other structures, colored target pixel points and transparent target pixel points are spliced in sequence to form the display device. Further, the size of each of the dotted symbols may be set according to the colored target pixel point. For example, for a dashed line symbol of a line structure, the width and length of the line may be controlled by the number of colored target pixel points, and the length of the interval between adjacent lines may be controlled by the number of transparent target pixel points. For example, as shown in fig. 3, for the dotted line symbol of the required black line structure, a single dotted line symbol is set, the line length of the line is 2 target pixel points, and the interval distance between two adjacent lines is 6 target pixel points. In the coloring process, 2 adjacent target pixel points in the picture to be processed are colored to be black through a coloring device, and the other 6 target pixel points are colored to be transparent, so that a needed broken line symbol of a black line structure is formed. It should be noted that, in fig. 3, the edges of the 6 hollow black circles are actually transparent and colored, and the black edges are only used as a number indication of the target pixel points.

In order to provide rich colors, in one embodiment, the preset colors are set according to color values. For example, according to the RGB color mode, the color values of red (R), green (G) and blue (B) can be set respectively, so that a plurality of different colors can be designed, thereby meeting the color identification requirement and being convenient for distinguishing the colors of other geographic elements in the electronic map.

Step S220, screen pixel coordinates and display quantity of the dotted line symbols are obtained according to the screen position information of the boundary line to be marked on the electronic map.

In the related art, for convenience of managing and tracking data, map data is generally hierarchically processed. Specifically, the map data may be divided into a plurality of data levels from top to bottom, and one upper layer data may correspond to a plurality of lower layer data, each layer expressing the communication characteristics of different roads. Different scales may correspond to different data levels. In this embodiment, the dotted line symbol is formed at the uppermost layer of the electronic map, that is, the dotted line symbol is displayed on the data level in the electronic map currently displayed on the screen. Further, a plurality of dotted symbols are displayed at the positions of the corresponding screens of the lines to be marked of the current data hierarchy. In one embodiment, the screen position information of the boundary line to be marked is the screen pixel coordinate of the boundary line to be marked, and the dotted line symbol may be displayed at the position of the screen pixel coordinate according to the screen pixel coordinate of the boundary line to be marked in the current data hierarchy.

In order to determine the display position of each dotted line symbol, in one specific embodiment, vertex geographic coordinates of each vertex of the boundary to be marked in the electronic map are obtained; and converting the geographic coordinates of the vertexes, and calculating to obtain the screen pixel coordinates corresponding to each vertex. In particular, a line is typically represented by an ordered set of points (coordinate pairs). And a line for bending or kinking that includes multiple vertices (also referred to as inflection points). Specifically, the boundary line to be marked is the position where the dotted line symbol needs to be displayed. The boundary line is not limited to the national boundary line or boundary line, but may be other ground objects or landforms that need to be represented by a broken line. In one embodiment, the line connecting every two adjacent vertexes is a straight line, and the vertexes are sequentially connected to form a bending boundary. When the electronic map is displayed on the screen, the vertex geographic coordinates of each vertex of the boundary to be marked in the current data level are obtained. The vertex geographic coordinates are longitude and latitude coordinates of the vertex. According to the data hierarchy of the current electronic map display, the screen pixel coordinates of each vertex can be obtained according to the related technology calculation. The position of the connecting line of every two adjacent vertexes can be determined through the screen pixel coordinates of each vertex. The position of the connecting line of every two adjacent vertexes is the display position of the dotted line symbol.

In order to determine the display quantity of each dotted line symbol, in one specific embodiment, the interval length between two adjacent vertexes is calculated and obtained according to the screen pixel coordinate of each vertex; accumulating the interval length between every two adjacent vertexes, and calculating to obtain the total length of the boundary line to be marked; and calculating to obtain the number of the dotted line symbols to be displayed according to the total length divided by the number of the target pixel points of the single dotted line symbol. For example, the dashed-line symbol of the black line structure in the above embodiment includes 2 colored target pixel points and 6 transparent target pixel points, i.e., a single dashed-line symbol includes 8 target pixel points. The total length of the boundary line to be marked is calculated, and then divided by 8, namely the number of the dotted line symbols to be displayed on the boundary line to be displayed. As shown in fig. 4, when the calculation results in that 3 dotted symbols need to be displayed, the three dotted symbols are connected end to end in order to form a dotted texture of the line structure.

In this step, the positions and the number of the display of the dotted line symbols can be determined by obtaining the screen pixel coordinates and the display number of the dotted line symbols.

In step S230, each of the dotted symbols is sequentially spliced according to the screen pixel coordinates and the display number of the dotted symbols to form a dotted texture picture and displayed on the screen.

It is understood that a picture is made up of target pixels having locations and colors. In one specific embodiment, a target pixel point in the dashed texture picture is identified, each target pixel point is colored according to a preset color, and a plurality of colored target pixel points form a dashed symbol. And according to the display quantity, splicing a plurality of dotted line symbols according to the pixel coordinate sequence of the screen to form a complete dotted line texture picture.

In the above embodiment, the target pixel point is colored and transparent according to the preset color to form a single dotted line symbol, and the plurality of dotted line symbols form a continuous and complete dotted line texture picture according to the corresponding screen pixel coordinates and the display number. Such a design is, on the one hand. The dotted line texture is displayed in the form of a picture, so that the needed dotted line texture is more easily configured and obtained; on the other hand, the needed dotted line effect can be realized on the electronic map by changing the picture without changing the map data in the electronic map, and the operation is simple and convenient.

Specifically, the apparatus described in the embodiment of the present application may implement part or all of the flow in the embodiment of the method for generating a dashed texture described in connection with fig. 1 to 4.

The preset color comprises at least one color set according to color values. Specifically, at least one colored target pixel point and at least one transparent target pixel point sequentially form a dotted line symbol according to preset positions.
