In this way, when performing typesetting in multi-line text lines, it is necessary to manually typeset the text of each line, set Attributes such as the alignment of each row to simulate the effect of typesetting in a row; or realize it with the help of a table, the specific implementation method is as follows:

(1) Manual typesetting: The typesetting personnel enter each line of text according to the layout requirements, set the text attributes, and manually adjust the alignment of each line of typesetting in the line;

(2) With the help of table typesetting: the typesetting staff inserts a table with N rows and 3 columns according to the number of rows N, the first column and the third column are respectively merged into one cell, and the cell properties are set to center alignment, and the cells in the middle column Set the text alignment in the cell, and enter each line of text, then set the borderless property of the table, and finally adjust the cell width property according to the amount of text. the

The disadvantages of the above two methods of implementing multi-line typesetting in lines are: manual typesetting is only suitable for in-line typesetting with an odd number of lines in total, and when the text format of in-line typesetting is different from the format of the text before and after it, it cannot be completely accurate. In-line typesetting; while table typesetting is time-consuming and laborious, reducing the efficiency of in-line typesetting. the

In order to better understand the present invention, the BD typesetting language involved in the present invention is now briefly introduced as follows: BD typesetting language is a computer language specially used by Peking University Electronic Publishing System to arrange books and periodicals, and is a special language for the Founder Book Edition system. Composed of more than 100 annotations, each annotation has its own function, specifies certain requirements of typesetting, and has a definite scope of action; each annotation of BD typesetting language has one or more parameters to choose from, and each parameter corresponds to a certain A function; multiple annotations can be used in combination to complete more complex layouts. the

(3) Analyze the BD typesetting language annotation in the sample file, obtain the typesetting parameters of the text to be typeset in the row, and generate the large sample file after typesetting according to the typesetting parameters;

(4) The large sample file browser parses the large sample file to obtain a specific typesetting effect. the

Further, the sequential input described in step (1) refers to sequential input from left to right, from high row to low row. the

The text to be typed includes the text to be typed in the row, the text before and after the text to be typed in the row, and punctuation marks. the

The symbols mentioned above refer to special characters for book editions, including space characters, hard return characters and end-of-file characters. the

Further, the BD typesetting language annotations in step (2) include in-line (HZ) annotations and annotations that can be used in conjunction with in-line annotations. the

The comment in the line refers to the comment of opening and closing arcs, the opening arc marks the start of the comment state in the line, and the closing arc marks the end of the comment state in the line, and the text between the open arc and the closed arc is the text to be typesetting in the line. the

Further, the typesetting parameters described in step (3) are obtained according to the context or the parameter setting interface set in the sample editor. the

The process of typesetting according to typesetting parameters includes the following steps:

1) Obtain the typesetting parameters of the first line: including character height, character width, character spacing, line height, line spacing, horizontal and vertical coordinates of the entry;

(1) Input the text and symbols to be typeset sequentially in the sample editor (see S11); the sequential input refers to inputting the text to be typeset in the row from high row to low row, and from left to right; The text to be typesetting includes the text to be typesetting in the row, the text before and after the text to be typesetting in the row, and punctuation marks; the

(2) Insert the BD typesetting language comment into the sample editor according to the user's requirements for the typesetting effect, mark the text to be typeset in the line as a whole according to the usage rules of the BD typesetting language note, and generate a sample file (see S12). The BD typesetting language annotations include HZ (inline) annotations and annotations that can be used in conjunction with HZ annotations, such as HT (Han Chinese) annotations 51 , DQ (alignment) annotations 71 and so on. The comment in the line refers to the comment of the open and closed arc. The opening arc 31 marks the start of the comment state in the line, and the closed arc 34 marks the end of the comment state in the line. The text between the open arc 31 and the closed arc 34 is the line to be Typographic text. the

(3) Analyze the BD typesetting language annotation in the sample file, obtain the typesetting parameters of the text to be typeset in the line according to the context or user settings, and generate the large sample file after typesetting according to the typesetting parameters (see S13). the

As shown in Figure 2, the specific process of typesetting includes the following steps:

1) Obtain the typesetting parameters of the first line: including character height, character width, character spacing, line height, line spacing, horizontal and vertical coordinates of the entry, etc. (see S201);

2) typeset the first line (see S202);

3) judge whether the typesetting of the first line is finished (see S203), if so, turn to step 4), otherwise turn to step 2);

4) Back up the typesetting parameters of the previous line to obtain the typesetting parameters of the next line (see S204);

5) Calculate the downward displacement of the text in the same line, and the horizontal and vertical coordinates of the entrance (see S205);

6) typesetting the line (see S206);

7) Judging whether the typesetting of the line is finished (see S207), if so, turn to step 8), otherwise turn to step 6);

8) The characters in the same line are displaced downwards (see S208);

9) Judging whether all rows are typesetting finished (see S209), if so, turn to step 10), otherwise turn to step 4);

10) The text before the typesetting text in the row is displaced downwards (see S210);

11) Calculate the horizontal and vertical coordinates of the text entry after the text to be typeset in the row (see S211);

12) The text after the text to be typeset in the typesetting row (see S212). the

Wherein, the specific process of typesetting in step 2) and step 6) includes the following steps:

①Calculate the horizontal and vertical coordinates of the first character in the line, and typeset the first character; 

②Judge whether the row is over, if yes, go to step ④, otherwise go to step ③; 

③Calculate the abscissa and ordinate of the next word in the row: abscissa = abscissa of the previous word+word width+word spacing, the ordinate remains unchanged, typesetting the word and then go to step ②; 

④The typesetting of this line is completed. the

In step 10), the calculation formula for the downward displacement of the text before the typesetting text in the row is: (the sum of the row heights of all rows+the sum of the row spacing between all rows-the text height before all rows )/2. the

(4) The large sample file browser parses the large sample file to obtain a specific typesetting effect (see S14), wherein the alignment methods of each line of text in a row include left alignment, right alignment, center alignment and scattered alignment. the

Example 1

Take the "cartoon:" and "coming soon" in the same row to enter "" Mickey Mouse and Donald Duck "," The Iron Fan Princess "," Brave Princess Sherry "" Finding Nemo "" as an example to describe the present invention The method is described in detail. The effect after typesetting is that the format of the text in the line is the same as that of the text before and after it, and the alignment is left-aligned, as shown in Figure 4. the

First, enter the text "Cartoon:" to the left of the text to be typeset in the row in the sample editor, and then input the text to be typeset in the row ""Mickey Mouse and Tang Lao "Duck", "Princess Iron Fan", "Brave Princess Sherry", "Finding Nemo", different lines are separated by the carriage return key, and finally enter the text "coming soon" after the text to be typeset in the line, and insert it for the book version at the same time characters, as shown in Figure 3. Wherein, 32 is a space character, 33 is a hard return character, 35 is a file end character, and 36 is a carriage return key. the

Secondly, add the HZ annotation in the BD typesetting language to the text to be typeset in the line input by the sample editor, and mark the text to be typeset in the line as a whole according to the usage rules of the HZ annotation. The HZ annotation is an open and closed arc annotation, an open arc marks the start of the HZ annotation state, and a closed arc marks the end of the HZ annotation state, and the text between the open arc and the closed arc is the text to be typeset in the line. In this embodiment, the result of using HZ annotation to mark ""Mickey Mouse and Donald Duck", "The Iron Fan Princess", "Brave Princess She-Ra", and "Finding Nemo"" is shown in Figure 3 . Among them, 31 is an open arc, and 34 is a closed arc. the

Thirdly, start the "text typesetting" function in the sample editor, analyze the HZ annotation in the sample file, obtain the typesetting parameters according to the above, and generate a large sample file after typesetting. The parameters and calculation formulas involved in the typesetting process are as follows. the

(1) Obtain character width zk, character spacing zj, character height zg, line height hg, line spacing hj, current abscissa x, and current ordinate y according to the above or below; the current abscissa and ordinate are the first line The point coordinates of the upper left corner of the typesetting area of the first character, the current horizontal and vertical coordinates in this embodiment are the point coordinates of the upper left corner of "《". the

(2) Calculate the following parameters according to the obtained above parameters:

The horizontal and vertical coordinates of the entry of each row of text to be typeset in the row: the horizontal and vertical coordinates of the entry of each row are the same, and they are the current horizontal and vertical coordinates x and y. the

The abscissa of the exit of each row is the pre-arrangement abscissa x _n of the next word obtained after the last word of each row is arranged, x _n =x _n-1 +(zk+zj)*m _i , x ₁ =x. The downward displacement amount of each row: d _n =d _n-1 +hj_1+zg_1, d ₁ =0.

The amount of displacement dy=the sum of the row heights of all rows+the sum of the row spacing between all rows of the text before the text to be typeset in the row (in this embodiment, "cartoon: ")-before all rows text height)/2

The abscissa and ordinate of the text entry after the text to be typeset in the row: Xc=Max(Xn), Yc=y+dy. the

The above-mentioned current horizontal and vertical coordinates refer to the coordinates of the upper left corner of the typesetting area of the first character in the first line; hj_1 is the line spacing between each line and the previous line, the first line is 0, zg_1 is the character height of the previous line, The first line is 0; m _i and n are variables, m _i represents the number of words in the i-th line, n represents the number of lines, n>2, 1≤i≤n.

Typesetting the content in the sample editor according to the above typesetting parameters to generate a large sample file. the

Finally, the large sample file browser parses the large sample file to obtain a specific typesetting effect, as shown in Figure 4. the

Example 2

The difference from Embodiment 1 is that the typesetting parameters of the text to be typeset in the row are not obtained according to the context, but are obtained according to the user-defined settings, so as to meet the user needs that the format of the text to be typeset in the row is different from the format of the text before and after it . During specific implementation, an interface for user-defined setting of typesetting parameters of the text to be typeset in the row can be provided in the sample editor. This interface may include setting parameters such as the font, font size, character spacing, line spacing, and alignment of the text to be typeset in the row. the

The typesetting effect obtained in this embodiment is shown in Figure 6. The alignment of typesetting text in a row is still left-aligned, but the font size of the text in the first and second lines is larger than the text in front of it, so the typesetting of these two lines Parameters cannot be obtained from the context, and parameters such as font size, word spacing, and line spacing can be customized through the parameter setting interface. When typesetting, the typesetting is done according to the parameters set by the user. If the user does not set the layout parameters of a line in the parameter setting interface, the layout parameters of the line are still obtained from the context. The BD typesetting language annotations inserted in the sample editor include HZ (inline) and HT (Han) 51 annotations, as shown in Figure 5. the

Example 3

The difference from Embodiment 1 is that the typesetting effect obtained is as shown in FIG. 8 , that is, the alignment method of each line of text in a row is scattered alignment. The BD typesetting language inserted in the sample editor includes HZ and DQ (alignment) 71 annotations, as shown in FIG. 7 . the

After realizing the left alignment of each line of text in the line, the process of typesetting a line includes the following steps: 

(1) Obtain the alignment word distance dzj, calculate the row width wide of the row and the abscissa Xc of the exit of the row, wherein, wide=dzj*(zk+zj), Xc=x+wide; x is the entry coordinate of the row; alignment character The distance can be set in the DQ annotation, as shown in Figure 7, or it can be set in the parameter setting interface; 

(2) Determine whether the line is over, if so, go to step (3), otherwise obtain the following parameters: word width zk, word spacing zj, and calculate the abscissa of each character in the line;

(3) Judging whether the bank is a single word, if so, move the word to the right (wide-zk)/2 and then turn to step (7), otherwise turn to step (4);

(4) Obtain the number of words in the bank n;

(5) The kth (1<k<n) word is shifted to the right by k*(wide-n*(zk+zj))/(n-1);

(6) Move the nth word to the right: wide-n*zk-(n-1)*zj;

(7) A row of typesetting is completed. the

Example 4

The difference from Embodiment 1 is that the typesetting effect requires that the text to be typeset in the row be right-aligned. Since there is no right-aligned annotation that can be used in conjunction with HZ annotations in the existing BD typesetting language, on the basis of Embodiment 1, by adjusting the coordinates of the text to be typeset in the left-aligned line, each line of text moves to the right Appropriate distance can achieve right-aligned typesetting effect. The calculation process of the right shift distance is: first calculate the line width of each line of the text to be typeset in the line, select the largest line width as a reference, and the displacement of each line to the right is equal to the maximum line width minus the line width of each line, and the line The widest row does not move. the

Example 5

The difference from Embodiment 1 is that the typesetting effect requires that the text to be typeset in the row be centered. Since the existing BD typesetting language does not have a center-aligned annotation that can be used in conjunction with the HZ annotation, on the basis of Embodiment 1, by adjusting the coordinates of the text to be typeset in the left-aligned line, each line of text moves to the right Appropriate distance can achieve right-aligned typesetting effect. The calculation process of the right shift distance is: first calculate the line width of each line of the text to be typeset in the line, select the largest line width as a reference, the displacement of each line to the right is equal to the maximum line width minus the line width of each line, and then Divided by 2, the row with the largest row width does not move. the

The method described in the present invention is not limited to the examples described in the specific implementation manners, and those skilled in the art can obtain other implementation manners according to the technical solutions of the present invention, which also belong to the technical innovation scope of the present invention. the
