Abstract

Provided are a character display method and apparatus, an electronic device, and a computer-readable storage medium. The character display method includes: receiving a display parameter; obtaining a to-be-displayed character; obtaining a texture of the to-be-displayed character; and displaying the texture of the to-be-displayed character on a screen based on the display parameter and an attribute of the texture of the to-be-displayed character. According to the method, the display parameter is received, and the texture of the to-be-displayed character is drawn based on the display parameter, which can solve the problem of inflexible controlling on the drawing of the character.

First claim

What is claimed is:

1. A character display method, comprising:
receiving a display parameter;
obtaining a to-be-displayed character;
obtaining a texture of the to-be-displayed character; and
displaying the texture of the to-be-displayed character on a screen based on the display parameter and an attribute of the texture of the to-be-displayed character,
wherein said displaying the texture of the to-be-displayed character on the screen based on the display parameter and the attribute of the texture of the to-be-displayed character comprises:
determining, based on the display parameter and the attribute of the texture of the to-be-displayed character, whether the texture of the to-be-displayed character is to be displayed in a wrapping manner;
determining a display position of the texture of the to-be-displayed character on the screen, based on the display parameter that corresponds to the determination and the attribute of the texture of the to-be-displayed character; and
displaying the texture of the to-be-displayed character on the screen based on the display position.

2. The character display method according to claim 1 , wherein said obtaining the to-be-displayed character comprises:
obtaining a to-be-displayed text; and
obtaining at least one to-be-displayed character by separating characters in the to-be-displayed text.

3. The character display method according to claim 1 , wherein said obtaining the texture of the to-be-displayed character comprises:
obtaining a character texture atlas; and
obtaining the texture of the to-be-displayed character from the character texture atlas.

4. The character display method according to claim 3 , further comprising obtaining a character mapping relationship table,
wherein said obtaining the texture of the to-be-displayed character from the character texture atlas comprises:
looking up the character mapping relationship table for a position of the texture of the to-be-displayed character in the character texture atlas; and
obtaining the texture of the to-be-displayed character from the character texture atlas based on the position,
wherein the character mapping relationship table comprises a mapping relationship between a character and a position of a texture of the character in the character texture atlas.

5. The character display method according to claim 4 , wherein the character texture atlas is generated by:
obtaining a single character;
generating, in response to absence of the single character in the character texture atlas, a texture of the single character based on a font attribute of the single character; and
drawing the texture of the single character in the character texture atlas.

6. The character display method according to claim 5 , further comprising:
obtaining a texture position of the texture of the single character in the character texture atlas;
determining a mapping relationship between the single character and the texture position; and
updating the character mapping relationship table based on the mapping relationship between the single character and the texture position.

7. The character display method according to claim 1 , wherein:
the display parameter comprises a line width; and
said determining, based on the display parameter and the attribute of the texture of the to-be-displayed character, whether the texture of the to-be-displayed character is to be displayed in the wrapping manner comprises:
calculating a width of a to-be-displayed character line, based on the attribute of the texture of the to-be-displayed character and an attribute of a texture of a character preceding the to-be-displayed character;
comparing the width of the to-be-displayed character line with the line width; and
determining, based on the comparing the width of the to-be-displayed character line with the line width, whether the texture of the to-be-displayed character is to be displayed in the wrapping manner.

8. The character display method according to claim 7 , wherein said determining, based on the comparing with the width of the to-be-displayed character line with the line width, whether the texture of the to-be-displayed character is to be displayed in the wrapping manner comprises:
determining, when the width of the to-be-displayed character line is smaller than or equal to the line width, that the texture of the to-be-displayed character is to be displayed in an unwrapping manner; and
determining, when the width of the to-be-displayed character line is greater than the line width, that the texture of the to-be-displayed character is to be displayed in the wrapping manner.

9. The character display method according to claim 7 , wherein said calculating the width of the to-be-displayed character line based on the attribute of the texture of the to-be-displayed character and the attribute of the texture of the character preceding the to-be-displayed character comprises:
calculating a first distance from a first border of the texture of the to-be-displayed character to a texture origin of the to-be-displayed character, wherein the texture origin is an origin of the texture of the to-be-displayed character in a character texture atlas;
calculating an origin of the texture of the to-be-displayed character on the screen based on an origin of the texture of the character preceding the to-be-displayed character on the screen, a size of the character, and a character spacing; and
calculating a first position based on the origin of the texture of the to-be-displayed character on the screen and the first distance, wherein the first position comprises a position of the first border of the texture of the to-be-displayed character on the screen, and the first position represents the width of the to-be-displayed character line.

10. The character display method according to claim 9 , wherein said comparing the width of the to-be-displayed character line with the line width comprises:
calculating a position of a first boundary of the to-be-displayed character line based on an origin of a texture of a first character of the to-be-displayed character line on the screen and the line width;
determining, when the first position exceeds the position of the first boundary, that the width of the to-be-displayed character line is greater than the line width; and
determining, when the first position does not exceed the position of the first boundary, that the width of the to-be-displayed character line is smaller than or equal to the line width.

11. The character display method according to claim 1 , wherein:
the display parameter comprises a character spacing, an initial origin position, and a line spacing; and
said determining the display position of the texture of the to-be-displayed character on the screen based on the display parameter that corresponds to the determination and the attribute of the texture of the to-be-displayed character comprises:
determining, in response to determining that the texture of the to-be-displayed character is to be displayed in an unwrapping manner, the display position of the texture of the to-be-displayed character on the screen based on a display position of a previous character to the to-be-displayed character, the character spacing, and the attribute of the texture of the to-be-displayed character; and
determining, in response to determining that the texture of the to-be-displayed character is to be displayed in the wrapping manner, the display position of the texture of the to-be-displayed character on the screen based on the display position of the previous character to the to-be-displayed character, the initial origin position, the line spacing, and the attribute of the texture o
