The vehicle-mounted handheld controller is electronic equipment adopting an embedded system. The vehicle-mounted handheld controller is mainly used for facilitating passengers (particularly rear-row passengers) in the automobile to control non-driving functions (including air conditioners, wifi, Bluetooth, audio and video and the like) of the automobile. The GUI system of the low-cost vehicle-mounted handheld controller can be realized based on a light-weight general-purpose graphic library. The Light and Vertical Graphics Library (LVGL) is a new GUI system framework, and has the advantages of small code amount and easy development of User Interface (UI).
LVGL currently supports only basic english and character icons by default in multi-language displays. For the display of other languages, a corresponding C-language bitmap description array needs to be generated for each character to be displayed, and the LVGL system stores and loads bitmap data of the character to be displayed, and then displays the bitmap data. In most cases, the characters to be displayed are uncertain (e.g., song names and person names in chinese or japanese), and thus it is necessary to store and load bitmap data of all the commonly used chinese or other language characters. Moreover, every time a font with a different size is added, a whole set of bitmap data corresponding to the size of the font needs to be added. However, the memory space of the embedded device system with low cost is limited, and if storing bitmap data of all common characters of a font, a large storage space needs to be added, which is high in cost.

The Memory 1005 may be a high-speed Random Access Memory (RAM) or a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001 described previously.
Those skilled in the art will appreciate that the configuration shown in fig. 1 is not intended to be limiting of the text display device and may include more or fewer components than shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a storage medium, may include therein an operating system, a network communication module, a user interface module, and a text display program.
In the text display device shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 of the text display device according to the present invention may be disposed in the text display device, and the text display device calls the text display program stored in the memory 1005 through the processor 1001 and executes the text display method according to the embodiment of the present invention.
Based on the text display device, an embodiment of the present invention provides a text display method, and referring to fig. 2, fig. 2 is a schematic flow diagram of a first embodiment of the text display method according to the present invention.
In this embodiment, the text display method includes the following steps:
step S10: and inquiring the primitive data corresponding to the characters to be displayed according to the information of the characters to be displayed.
It should be noted that the execution main body of the embodiment may be a computing service device with data processing, network communication, and program running functions, such as a mobile phone, a tablet computer, a personal computer, or an electronic device or a text display device capable of implementing the above functions. The present embodiment and the following embodiments will be described below by taking the above-described character display device as an example.
It should be noted that the text display device may be an electronic device that uses LVGL as a GUI system framework, and may be configured to display text information in TTF font. The text information to be displayed may be a TTF file of information to be displayed on the text display device. The text to be displayed may be text to be displayed on the text display device. The primitive data may be text outline definition values and grid adjustment instruction values.
It should be understood that the TrueType font design is designed for a reference grid, and the primitives in the font are represented by coordinates in the reference grid. The size of the reference grid thus determines the way in which the primitives for the font are scaled and also reflects the quality of the font. The vector information of the character comprises a font head of the font, and the font head stores the number of grids in each grid and a bounding box capable of containing all primitives. The primitive data is the core information of the TrueType font. The description of the primitive is composed of several pieces of information: all contour lines, primitive instructions, and a series of control points. Each control point includes a marker and x and y coordinates.
Contour line: the primitives may contain one or more contour lines. For example, the letter "O" has two contours, one being an inner contour and the other being an outer contour. The primitive outline is defined by a second order Bezier curve, with three points: points on one curve, points outside one curve and points on another curve.
And (3) control points: the control points for the primitives are stored in three arrays: a flag array, an x-coordinate array, and a y-coordinate array. Some type of run length coding is actually used in the flag array. The other bits of the flag are used to describe the encoding of the corresponding x and y coordinates, which may indicate whether the current phase-finding coordinate is the same as the last, positive one-byte value, negative one-byte value, or signed two-byte value.
Primitive instruction: when the font size is changed, the method is used for controlling the transformation of the outline of the primitive in the grid.
Further, in order to enable the text display device to display more texts, before step S10, the method further includes: when a vector information pre-storing instruction is received, determining vector information to be stored according to the vector information pre-storing instruction; and storing the vector information to be stored into a preset vector information base.
It should be noted that the vector information pre-storing instruction may be an instruction sent by the user to the text display device to store the vector information of each text set in advance, where the vector information of each text set in advance by the user is included. The vector information to be stored may be the vector information corresponding to the characters preset by the user. The preset vector information base may be a database or a data table in the text display device for storing vector information to be stored. And storing the graphic primitive data corresponding to the characters to be displayed in the vector information corresponding to the characters to be displayed. The preset vector information base can store the vector information of commonly used Chinese characters and the vector information of commonly used characters such as Japanese and Korean characters.
Further, since the vector information corresponding to all the characters may not be generally contained in the preset vector information base, some characters in the characters to be displayed may not store their corresponding vector information in the preset vector information base, and at this time, the characters that do not store their corresponding vector information in the preset vector information base cannot be displayed by the character display device, so that, in order to reduce the reading hindrance of the user as much as possible when the above situation occurs, after the step S10, the method further includes: when the primitive data corresponding to the characters to be displayed are not inquired, acquiring preset filling data; and taking the filling data as the graphic element data of the characters to be displayed.
It should be noted that the preset padding data may be preset data used as primitive data of a character when the primitive data corresponding to the character is not found. Can be a custom padding identification.
Step S20: and generating dot matrix bitmap data of the characters to be displayed according to the primitive data.
It should be noted that, the generating of the dot matrix bitmap data of the text to be displayed according to the primitive data may be dynamically generating dot matrix bitmap data corresponding to the text to be displayed by calling a decoding method of a TTF format parsing library according to the primitive data and font size information set by a user by a TTF text parser in the text display device. The font size information set by the user may include the size of the font set by the user, line spacing, word height, word width, word spacing, whether to thicken, and the like.
In a specific implementation, a specific process of generating dot matrix bitmap data from primitive data of a text, that is, a decoding manner, may be:
s1, judging whether the size of the characters changes: if the size of the character is changed, executing a primitive instruction to obtain a transformed outline and a control point; if the size is not changed, no transformation is needed;
s2, scanning the contour line of the character primitive data and the control points on the contour line as the input of the matrix transformation operation formula;
s3, performing matrix operation to obtain a two-dimensional array description value of the two-dimensional spatial position;
s4, calculating and outputting the specific dot matrix bitmap data according to the description value and the bitmap format.
Step S30: and displaying the characters to be displayed according to the dot matrix bitmap data.
It should be noted that the displaying of the text to be displayed according to the dot matrix bitmap data may be a drawing of the text according to the dot matrix bitmap data in a preset drawing manner, so as to display the text to be displayed.
In the embodiment, the primitive data corresponding to the characters to be displayed are inquired according to the information of the characters to be displayed; generating dot matrix bitmap data of the characters to be displayed according to the primitive data; and displaying the characters to be displayed according to the dot matrix bitmap data. In the embodiment, the dot matrix bitmap data of the characters to be displayed is generated according to the primitive data corresponding to the characters to be displayed; and displaying the characters to be displayed according to the dot matrix bitmap data. Compared with the existing mode of displaying characters through bitmap data of all characters to be displayed, the mode of the embodiment can save storage space and reduce character display cost.

Based on the first embodiment described above, in the present embodiment, the step S10 includes:
step S101: and pre-compiling the character information to be displayed to obtain binary character information.
It should be noted that the pre-compiling the text information to be displayed may be to store the original binary RAW data corresponding to the text information to be displayed as an array of unsigned bytes of C language, and store the array in a C file. The array of the unsigned bytes of the C language is a data source of the TTF format file, and each unsigned byte in the array is binary data of RAW of the TTF format file; simultaneously recording the structure body variable of the font file in the C file; the structure body adopted by the structure body variable comprises a structure body and a data pointer. And compiling the C file into a binary file and storing the binary file into a firmware image file at the stage of pre-compiling the character information to be displayed, so as to obtain the binary character information.
Step S102: and inquiring a preset vector information base according to the binary character information to obtain the vector information of the characters to be displayed.
It should be noted that the preset vector information base may be a database or a data table for storing each character and its corresponding vector information. The querying of the preset vector information base according to the binary text information may be determining vector information corresponding to each text to be displayed from the preset vector information base according to the binary text information.
Step S103: and determining the primitive data corresponding to the characters to be displayed according to the vector information.
It should be noted that, the determining, according to the vector information, the primitive data corresponding to the text to be displayed may be to acquire the primitive data corresponding to the text to be displayed from the vector information.
Further, in order to reduce the storage cost of the text display device when displaying the text through the text display device, the step S103 may include: determining the character code of each character in the characters to be displayed according to the vector information; inquiring a preset character index table according to the character codes to obtain the position of the primitive data; and determining the primitive data of each character in the characters to be displayed according to the primitive data position.
It should be noted that the character code may be a unicode code of each of the texts to be displayed. The preset character index table may be a comparison table for storing positions of each character and corresponding primitive data. And inquiring a preset character index table through the character codes of all the characters to obtain the primitive data positions of the primitive data corresponding to the characters, and obtaining the primitive data of all the characters in the characters to be displayed according to the primitive data positions.
The embodiment pre-compiles the text information to be displayed to obtain binary text information; inquiring a preset vector information base according to the binary character information to obtain vector information of characters to be displayed; and determining the primitive data corresponding to the characters to be displayed according to the vector information. According to the embodiment, binary text information is obtained by pre-compiling the text information to be displayed; inquiring a preset vector information base according to the binary character information to obtain vector information of characters to be displayed; and determining the primitive data corresponding to the characters to be displayed according to the vector information. And then can according to wait to show the primitive data that the characters correspond and treat and show the characters, for the current mode that carries out the characters display through the bitmap data of each character to be shown, this embodiment above-mentioned mode treats and shows the characters and can save storage space through the primitive data that the characters to be shown correspond, reduces the characters display cost.
Referring to fig. 4, fig. 4 is a schematic flow chart of a text display method according to a third embodiment of the invention.
Based on the foregoing embodiments, in this embodiment, the step S20 specifically includes:
step S201: and determining character display information according to the character information to be displayed.
It should be noted that the text display information may include information set by the user, such as a display font size, a font height, a font width, a line spacing, a font spacing, and whether to display text in bold or italic.
Step S202: and acquiring the global font information of the characters to be displayed.
It should be noted that the font global information of the text to be displayed may be font header information of the text to be displayed stored in the vector information corresponding to the text to be displayed, where the font header information includes a size of a font corresponding to primitive data of the font stored in the vector information corresponding to the text to be displayed. For example, if the font header information is 1 in the vector information of a certain character a to be displayed, the size of the displayed character is 1 after the character display is performed on the primitive data in the vector information corresponding to the character a to be displayed.
Step S203: and generating dot matrix bitmap data of the characters to be displayed according to the character display information, the font global information and the primitive data.
It should be noted that, the generating of the dot matrix bitmap data of the text to be displayed according to the text display information, the font global information, and the primitive data may be adjusting the primitive data according to the font size in the text display information and the font size in the font global information, and generating the dot matrix bitmap data of the text to be displayed according to the adjusted primitive data. For example, the font size in the text display information is 2, and the font size in the font global information is 1, it is known that the font size of the text to be displayed set by the user is twice the font size stored in the vector information of the text to be displayed, and therefore, when displaying the text, it is necessary to adjust the primitive data first, so that when displaying the adjusted primitive data, the font size of the displayed text is the font size set by the user. And after the primitive data are adjusted, generating dot matrix bitmap data of the characters to be displayed according to the information such as character height, character width, line spacing, character spacing, whether to display in bold or italic and the like in the character display information.
