Referring to fig. 2, a flow chart of a method for adjusting a character spacing according to an embodiment of the present application is shown. As shown in fig. 1, the method of the embodiment of the present application may include the steps of:
s201, receiving a display instruction of characters.
The characters are characters to be displayed on the serial port screen, the number of the characters to be displayed can be one or more, and when the number of the characters is multiple, the characters can comprise one or more of Chinese characters, English characters and other types of characters. The display instruction may be triggered by the user through an input device or a timer or otherwise, such as: the user triggers a display instruction of a certain character through a keyboard or triggers when a timer detects that the current time is a preset time.
S202, inquiring width data associated with the characters in a character library.
The method comprises the steps that a character library is prestored in a memory of the electronic equipment, and the character library comprises a plurality of characters and width data of each character; each character corresponds to a pixel matrix, the pixel matrix is stored in a memory of the electronic device in the form of pixel data, the pixel matrix of each character has the same size, and the shape of the pixel matrix is generally square. For example: the pixel matrix of each character comprises 16 × 16 pixels, namely 16 rows and 16 columns of pixels, the pixels are display units with the minimum granularity on a serial port screen, each pixel in the pixel matrix corresponds to one pixel data, the bit width of each pixel data is the same, the pixel data comprises a red value R, a green value G and a blue value B, the bit width of each color is 8 bits, the maximum value is 255, the minimum value is 0, and then the bit width of the pixel data is 24 bits; when the pixel data is gray-scale pixel data, the red value R is changed to the red value G and is changed to the blue value B, and further, the pixel data further includes a transparency value, which can be smoothed with the edge of the character to reduce the sharpness of the character when the character is displayed. The width data of the present application includes the width of a character in a pixel matrix, the serial number of a start pixel column, and the serial number of an end pixel column. Further, when the encoding format of the characters is ASCII, the associated width data is queried in the character library according to the code values.
For example: referring to fig. 3, the pixel matrices of the characters "i", "a", and "W" are all 16 × 16 pixels in size, the width of the character "i" is 5 pixels, the serial number of the starting pixel column is 6, and the serial number of the ending pixel column is 10; the width of the character "a" is 8 pixels, the serial number of the starting pixel column is 5, and the serial number of the ending pixel column is 12; the width of the character "W" is 10 pixels, the number of the start pixel column is 4, and the number of the end pixel column is 13.
Further optionally, the character library of this embodiment is a GB2312 character library, the character library includes a plurality of partitions, each partition includes a plurality of characters, width data of each character may be stored in the partitions 10 to 15, the partitions 10 to 15 are reserved partitions, and storing the width data in these partitions may effectively utilize a storage space of the character library.
For example: referring to 96 characters shown in FIG. 4, the size of the pixel matrix of each character is 32 × 32 pixels, the width data corresponding to 96 characters is shown in FIG. 5, and the character "! "is 5 pixels wide and the character" # "is 20 pixels wide.
Further, the width data of the present application is determined by scanning with a computer device, and the method includes:
the computer equipment acquires a pixel matrix of the character;
scanning the pixel matrix to obtain a starting pixel column, an ending pixel column and a width of the character, and generating width data according to the width, the serial number of the starting pixel column and the serial number of the ending pixel column;
the width data and the pixel matrix are burned into a memory of the electronic device.
In this embodiment, the pixels in the pixel matrix are binary pixels, that is, the color values of the pixel data are only two, 0 and 255, 255 represents white, 0 represents black, and the display effect of the character is a white-on-black character. After the computer device acquires a pixel matrix of a character, performing column scanning on the pixel matrix, performing column scanning from left to right, and when a first non-full-black pixel column (including at least one white pixel, the full-black pixel column indicates that all the pixels are black) is scanned, the pixel column is a starting pixel column, and recording the position (for example, a serial number) of the starting pixel column; then, the column scanning is performed from right to left, when the first non-all black pixel column is scanned, the display column is an end display column, the position (for example, serial number) of the end pixel column is recorded, and the width between the start pixel column and the end pixel column is calculated, and the width is expressed by the number of pixels. Therefore, the width data are calculated in advance by the computer equipment and then sent to the electronic equipment, so that the processor of the electronic equipment does not spend the calculation capacity to scan the width data of the characters in the pixel matrix, and the consumption of the calculation capacity of the processor can be reduced.
And S203, determining a pixel matrix of the character.
The memory stores pixel matrixes of each character, and queries the associated pixel matrixes according to the identifier of the character, for example: and querying a corresponding pixel matrix according to an ASCII (American Standard Code for Information exchange) Code value of the character.
And S204, adjusting the width of the pixel matrix based on the width data.
The width of the pixel matrix is adjusted according to the width data, and the adjusting method comprises the following steps: the pixel rows of the pixel matrix remain unchanged and the range of the pixel columns is determined according to the sequence number of the starting pixel column and the sequence number of the ending pixel column.
For example: referring to fig. 3, the width data according to the queried character "i" is expressed as: the width is 5 pixels, the number of the starting pixel column is 6, the number of the ending pixel column is 10, then the pixel row of the adjusted pixel matrix remains unchanged, the pixel columns are adjusted to be pixel columns No. 6 to 10, then the character "i" adjusted pixel matrix is represented as: pixel rows 1-16, pixel columns 6-10.
And S205, displaying the adjusted pixel matrix on the serial port screen according to the preset character interval.
The electronic device presets a character interval between two adjacent characters, and when a plurality of characters are displayed, the character interval between any two characters is equal, for example: the character pitch is 2 pixels. The pixel matrix is displayed on the serial port screen according to the adjusted pixel matrix, so that the intervals of all characters on the serial port screen are equal, and the display effect is more attractive.
For example: referring to the final display effect diagram of each character shown in fig. 6, it can be seen that the character spacing is the same for characters of different widths.
According to the scheme of the embodiment of the application, when the characters are displayed on the serial port screen, the width data and the pixel matrix of the pre-stored characters are acquired, the width of the pixel matrix is adjusted according to the width data, then the adjusted pixel matrix is displayed according to the preset character interval, the processor directly utilizes the pre-configured width data to display the characters, the character interval between the characters can be guaranteed to be equal, the better display effect is achieved, in addition, the processor of the display device does not spend the calculation capacity to scan the width data of the characters in the pixel matrix, and the consumption of the calculation capacity of the processor can be reduced.
