Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and embodiments.
Shown in Figure 1, the embodiment of the present invention provides a kind of method for optimizing barrage display effect, and this method includes following
Step:
S1. the dot character library file of Chinese character is read into memory.
The dot character library file for the Chinese character that the embodiment of the present invention uses is the dot character library file of 16*16, reads Chinese character
Dot character library file into memory specifically includes the following steps:
FILE*fphzk=fopen (" HZK16 ", " rb "), calling system api function fopen open dot character library file
HZK16；
Fseek (fphzk, 0, SEEK_END), calling system api function fseek move file pointer to dot-matrix library text
Part tail portion；
The size of int nFileLen=ftell (fphzk), calling system api function ftell acquisition dot character library file
nFileLen；
Fread (buffer, 1, nFileLen, fphzk), calling system api function fread read dot character library file and arrive
In memory, so far the content of entire dot character library file then all be read in buffer memory；
Fclose (fphzk), last calling system api function fclose close file handle fphzk.
S2. the lattice information of a specific Chinese character is obtained by reading the dot character library file of Chinese character, lattice information includes
Available point and background dot, available point is for constituting the specific Chinese glyph.
The embodiment of the present invention is set about from encoding of chinese characters mode, in the dot matrix word library of Chinese character, each position of each byte
A point of a function is represented, each function is made of the dot matrix of a rectangle, and 0 representative does not have, and 1 representative has, by 0 He
1 is drawn with different colors respectively, is formed a Chinese character.The embodiment of the present invention obtains the dot matrix letter an of Chinese character first
Breath, has lattice information to be known that the shape and format of Chinese character, lattice information is divided into available point and background dot here, wherein having
Effect point is for constituting the specific Chinese glyph.For black and white font, the black point diagram for being 1 is available point, is 0 point diagram
White is background dot.Shown in Figure 2, for " I " word barrage sent in direct broadcasting room, stain therein is available point, is used for
Constitute " I " glyph.
In the embodiment of the present invention, obtain the lattice information of a specific Chinese character specifically includes the following steps:
S21. offset of the specific Chinese character in dot character library file is obtained by specific Chinese character；
A Chinese character occupies two bytes in a computer, and previous byte is area's code of the Chinese character in the two bytes,
The latter byte is the position code of the Chinese character.Wherein each area records 94 Chinese characters, and position code is the position of the Chinese character in this zone.Institute
Its area's code and position code must be just obtained to obtain offset of the Chinese character in dot matrix word library.
For area's code, the first character of specific Chinese character is reduced 160 and obtains area's code of specific Chinese character, because of encoding of chinese characters
160th area Shi Cong starts.
Similarly for position code, second byte of specific Chinese character is subtracted 160 and obtains the position code of specific Chinese character.
Then the specific Chinese character is calculated in dot-matrix according to formula Offset=(94* (area's code -1)+(position code -1)) * 32
Offset in library file.
Wherein each area's record of 94 expressions is 94 Chinese characters.Area's code -1 and position code -1 indicate that starting subscript is in computer
Since 0.32 indicate that the lattice information of each Chinese character is made of 32 bytes.
Below by taking " I " word as an example, calculation is as follows:
The value of corresponding 2 bytes of " I " this Chinese character first is, and: 0xce 0xd2 (16 system) brings above formula into
It is then available
Offset=(94* (0xce-1)+(0xd2-1)) * 32.
S22. the offset according to the specific Chinese character in the dot character library file obtains the dot matrix of the specific Chinese character
Information.
After step S21 obtains offset, code=Buffer [offset] reads 32 by offset in dot character library file
A byte obtains the lattice information of specific Chinese character.
S3. the quantity of the available point of specific Chinese character is obtained.
After the lattice information for obtaining specific Chinese character, the quantity of the specific Chinese character available point can be obtained.Institute referring to fig. 2
Show, by taking " I " word as an example comprising 69 available points.
S4., first threshold is set, and the size of first threshold is less than or equal to the quantity of the available point of specific Chinese character, when current screen
When the quantity for occurring the specific Chinese character in the barrage of curtain reaches first threshold, the specific Chinese character in barrages all in screen is deleted
It removes, each available point of specific Chinese character is replaced with into specific Chinese character, generate the biggish specific Chinese character of a font.
Specifically, setting first threshold be 50, after many spectators have sent " I " this word, the embodiment of the present invention it is excellent
Change scheme is according to the quantity for occurring " I " in screen, if reaching first threshold, " I " all in screen is deleted,
Each available point of " I " is replaced with into " I ", so that it is biggish " I " to generate a font.
Further, it is also possible to make adjusting according to the quantity for occurring " I " in practical barrage, second threshold is set, when current screen
Curtain barrage in occur the specific Chinese character quantity reach second threshold and be less than first threshold when, then by acquired font compared with
The big specific Chinese character carries out reduction operation；When the quantity for occurring the specific Chinese character in the barrage of current screen is more than described
When the quantity of the available point of specific Chinese character, then the biggish specific Chinese character of acquired font is amplified into operation.
Specifically, setting second threshold is 35, when the quantity of " I " occurred in the barrage of screen is greater than 35 less than 50,
Font biggish " I " will be then obtained in step S4 and carries out reduction operation, when the quantity of " I " that occurs in the barrage of screen is greater than
When 69, then font biggish " I " will be obtained in step S4 and amplifies operation.
In conclusion the embodiment of the present invention is set about from encoding of chinese characters mode for a large amount of repetition barrages occurred in screen,
The lattice information for obtaining specific Chinese character obtains the quantity of the middle available point of the specific Chinese character, first threshold is then arranged, judges bullet
Whether the quantity of the specific Chinese character occurred in curtain reaches first threshold, will be specific in barrages all in screen if reaching
Chinese character is deleted, and each available point of specific Chinese character is replaced with specific Chinese character, generates the biggish specific Chinese character of a font, thus
Improve live video viewing effect.
