Next, a character display method disclosed in an embodiment of the present application is described, referring to fig. 1, which may include:
and step S11, acquiring outline description data of the character to be displayed from the reference word stock.
The outline description data may define the font size and font type of the character.
The font size can be understood as: the size of a character is generally in px (i.e., how many pixels are).
The font can be immediately: the shape of the character.
In this embodiment, one word stock may be selected from the word stock set as the reference word stock.
It is understood that the reference character library corresponds to a font, and the reference character library includes outline description data of each character for describing an outline of any character size of the font of each character.
And step S12, drawing the outline which conforms to the structure of the font corresponding to the reference font library according to the outline description data to be used as a primary outline.
And step S13, judging whether the font to be used of the character to be displayed is the font corresponding to the reference font library.
If so, go to step S14, otherwise, go to step S15.
The font to be used for the characters to be displayed can be understood as: and displaying the character to be displayed by using the font needed to be used.
And step S14, performing color filling on the primary contour, and displaying.
And step S15, obtaining a font conversion model corresponding to the font to be used.
If the font to be used of the character to be displayed is not the result of the font corresponding to the reference font determined in step S13, the primary outline needs to be converted into the outline corresponding to the font to be used. Specifically, a font conversion model corresponding to the font to be used is obtained first.
And the font conversion model is obtained by utilizing the outline drawn by the training characters according to the font corresponding to the reference font library and the outline drawn according to the target font.
It should be noted that there are multiple font conversion models, the fonts corresponding to different font conversion models are different, and the font corresponding to each font conversion model is different from the font corresponding to the reference font library.
Step S16, inputting the primary contour into the font conversion model, and obtaining a contour, which is output by the font conversion model and conforms to the structure of the font to be used, as a first target contour.
And step S17, performing color filling on the first target contour and displaying the first target contour.
Describing the process of steps S11-S17 by way of example, please refer to fig. 2, where the font library 1 is a reference font library, the font conversion models are models 1-2, 1-3, and 1-4, respectively, the font to be used of the character to be displayed is a font corresponding to the model 1-2, first, outline description data of "middle" is obtained from the font library 1, an outline of "middle" is drawn according to the outline description data, the outline of "middle" drawn according to the font library 1 is input to the model 1-2, the outline of "middle" conforming to the structure of the font to be used is output by the model 1-2, and the outline of "middle" conforming to the structure of the font to be used is color-filled and displayed.

And step S25, judging whether outline description data of the character to be displayed exists in a preset small word stock.
If yes, step S26 is executed, and if not, step S28 is executed.
It should be noted that, when the font conversion model performs the outline conversion, the outline obtained by the conversion may have a larger difference from the standard outline, and the conversion accuracy is reduced.
And step S26, drawing an outline which conforms to the structure of the font to be used as a second target outline according to the outline description data.
And step S27, performing color filling on the second target contour and displaying the second target contour.
And step S28, obtaining a font conversion model corresponding to the font to be used.

Step S29, inputting the primary contour into the font conversion model, and obtaining a contour, which is output by the font conversion model and conforms to the structure of the font to be used, as a first target contour.
And step S210, performing color filling on the first target contour, and displaying.
The detailed procedures of steps S28-S210 can be referred to the descriptions of S15-S17 in the previous embodiment, and are not described herein again.
In this embodiment, on the basis that the font to be used of the character to be displayed is not the font corresponding to the reference font library, it is first determined whether outline description data of the character to be displayed exists in a preset small font library, and under the condition that the outline description data of the character to be displayed exists in the preset small font library, an outline conforming to the structure of the font to be used is drawn according to the outline description data, and under the condition that the outline description data of the character to be displayed does not exist in the preset small font library, a font conversion model corresponding to the font to be used is obtained, and the outline is converted by using the font conversion model, so that the accuracy of outline conversion is improved, and further, the accuracy of character display is improved.

And step S32, comparing the difference between the third target contour and the standard contour of the font corresponding to the character to be detected and conforming to the font conversion model, and obtaining a comparison result.
And step S33, if the comparison result does not meet the preset standard difference condition, storing the standard outline description data of the character to be detected into a preset small word stock.
The preset standard difference condition can be flexibly set according to needs.
Generally, the primary or target profile in the foregoing embodiments is a gray-scale lattice. Based on this, in another embodiment of the present application, a process of training the font conversion model is described, please refer to fig. 5, which may include:
step S41, a reference word stock and a target word stock are obtained, the target word stock is a word stock in the word stock set except the reference word stock, and the font corresponding to the target word stock is different from the font corresponding to the reference word stock.
And step S42, drawing the outline of the training character according to the font corresponding to the reference character library to be used as a reference training outline.
According to the font corresponding to the reference word stock, drawing the outline of the training character may include: and drawing outlines of different font sizes of the training characters according to the fonts corresponding to the reference font library.
Generally, 256 pixels are selected as the maximum word size of the training character, and word sizes smaller than 256 pixels can participate in training.
For Chinese character library, a character complete set can be obtained from GBK (Chinese Internal Code Specification), and all characters in the character complete set can be used as training characters.
In addition, how many characters are contained in the word stock is explicitly described in the word stock, so that all characters can be directly searched from the word stock (such as a reference word stock and a target word stock) to be used as training characters.
And step S43, drawing the outline of the training character and the target training outline according to the font corresponding to the target font library.
Similarly, drawing the outline of the training character according to the font corresponding to the target word stock may include: and drawing outlines of different font sizes of the training characters according to the fonts corresponding to the target font library.
And step S44, forming a training contour pair by the reference training contour and the target training contour of each training character, and training the font conversion model.
It should be noted that, when the trained font conversion model is used to convert the outline, if the font size of the character to be displayed is greater than 256 pixels, the font conversion model may output the outline of 256 pixels that conforms to the structure of the font to be used, perform color filling to obtain font data, and then amplify and display the font data.
Based on the content in the foregoing embodiment, when the reference word stock is selected, the word stock corresponding to the font with relatively little change may be used as the reference word stock.
