Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
Example one
The invention provides a method for automatically generating an expression picture, which can dynamically generate the expression picture with user input content according to the user input content, solves the problems of low timeliness, complex operation and the like caused by the fact that a user needs to synthesize the input content and the picture according to picture editing software to generate the expression picture in the prior art, and greatly improves the picture generation speed.
As shown in fig. 1, the present invention provides a preferred embodiment, a method for automatically generating an emoticon, which specifically includes the following steps:
and step S1, acquiring the content input by the user. The content of the user input is derived by identifying the content of the user input. For example, the content input by the user is: "I am a Chinese. ".
And step S2, after the user input is finished, determining the size of the canvas according to the content input by the user, and generating the canvas.
The system also defines an end-of-user-input flag, for example, a punctuation mark is used as a flag to indicate that the user input is completed.
And the size of the canvas is the same as that of the finally generated expression picture. The size of the canvas is determined according to the number of characters of the content input by the user.
As shown in fig. 2, the step S2 specifically includes:
and step S21, calculating the number of characters in the content input by the user and calculating the line number of all the arranged characters and the number of characters in each line. When the number of input characters is large, it is necessary to arrange a plurality of characters in rows for the sake of good appearance. That is, the number of characters in each line is known by dividing the character into a plurality of lines according to the number of characters.
Such as: "I is a Chinese person, and the Chinese person,
i love China. ":
wherein: "I" "is" "middle" "state" "man" "and" is divided in the first row,
"I", "love", "middle", "country" and "the like". "divide in the second row.
As can be seen from the above example, the number of rows of the character array is 2. The characters in this document include not only chinese characters but also various characters such as punctuation marks, english alphabets, numerals, and the like.
And step S22, obtaining the number of lines of picture arrangement in the canvas and the number of pictures in each line according to the number of lines of all the character arrangements and the number of characters in each line.
Since one character in the present invention matches one picture, the number of lines in which the characters are arranged is the number of lines in which the picture is arranged. Preferably, the pictures in this embodiment may be cartoon pictures, landscape pictures, etc.
And step S23, calculating the maximum X-axis length and the maximum Y-axis length required by all the pictures in each row according to the number of the arranged rows of the pictures, the number of the pictures in each row and the size of each picture.
Because the pictures in the system have a certain size, in order to ensure that the pictures do not cover front and back when being arranged in the canvas, the maximum X-axis length and the maximum Y-axis length required by each row of pictures are calculated according to the size of each picture. Preferably, the pictures in this embodiment are all the same size. The X axis and the Y axis referred to herein are coordinate axes in a rectangular coordinate system composed of the top left corner of the current window as a vertex, the horizontal direction as the X axis, and the vertical direction as the Y axis.
And step S24, calculating the length and width of the canvas according to the maximum X-axis length and Y-axis length required by all pictures in each row and the row number of the arranged pictures.
Because the maximum X-axis length and the Y-axis length required by each row of pictures are known, and the number of rows of the arranged pictures is also known, the length and the width of the canvas can be calculated according to the maximum X-axis length and the Y-axis length.
And step S25, generating the canvas according to the length and the width of the canvas. And when the length and the width of the canvas are calculated, namely the size of the canvas, generating the canvas according to the size of the canvas, and preparing for generating the expression picture in the next step.
Further, the method for automatically generating the expression picture further comprises the following steps:
and step S3, circulating each character in the content input by the user, randomly matching a picture for each character and synthesizing a corresponding character expression, and then combining all the character expressions on the canvas. The number of pictures in this embodiment is not only one, but may be plural, but the sizes thereof are the same.
In addition, since there may be multiple pictures on the canvas, the position of each picture on the canvas is determined by the content input by the user.
As shown in fig. 3, the step S3 specifically includes:
and step S31, matching the corresponding pictures for each character in the content input by the user at random in sequence. Matching pictures for each character is performed randomly according to pictures existing in the system, such as "i am a chinese and i love china. ", which has 11 characters, a picture is randomly matched for each character, respectively.
And step S32, combining each character with the corresponding picture to generate the character expression corresponding to each character. During combination, in order to ensure that the obtained visual effect of the character expression is better, the combined character expression can be correspondingly adjusted according to the shape of the corresponding picture, for example, characters in the character expression are correspondingly inclined.
In this embodiment, each character is merged with the matched picture by calling a merging program in the system to generate a character expression corresponding to each character.
And step S33, merging each character expression to the corresponding position of the canvas according to the arrangement sequence of the characters in the content input by the user.
Because the characters in the content input by the user all have a certain sequence, the character expression corresponding to each character is consistent with the sequence of the characters when the characters are arranged in the canvas.
Such as: the first column of the first row of the canvas corresponds to the character expression of 'I';
"yes" corresponding character expression is in the first row and the second column of the canvas;
the corresponding character expression of "middle" is in the first row and the third column of the canvas;
the character expression corresponding to the country is in the fourth column of the first row of the canvas;
the character expression corresponding to the person is in the fifth column of the first row of the canvas;
"," the corresponding character expression is in the sixth column of the first row of the canvas;
the character expression corresponding to the 'I' is arranged on the second row and the first column of the canvas;
the character expression corresponding to the love is arranged on the second row and the second column of the canvas;
the corresponding character expression of "middle" is in the third column of the second row of the canvas;
the character expression corresponding to the country is in the fourth column and the second row of the canvas;
". "the corresponding character emoticons are in the second row and the fifth column of the canvas.
Further, after the canvas is generated, the method for automatically generating the emoticon further comprises:
and step S4, generating the expression picture according to the canvas and displaying the expression picture to the user.
And when each character in the content input by the user is matched with the generated corresponding character expression and is combined with the canvas, directly generating an expression picture according to the canvas and displaying the expression picture to the user. From the above, the method and the device can automatically match the corresponding pictures for the content input by the user according to the content input by the user and automatically synthesize the input content and the pictures to generate the corresponding expression pictures. The method can automatically generate the expression picture with the input content according to the input content of the user, does not need manual operation in the whole process, and can automatically generate the expression picture.
