Description

A Method of Automatically Separating Text Blocks into Columns According to the Background Grid

technical field

The invention belongs to the field of printing and typesetting, and in particular relates to a method for automatically separating text blocks into columns according to the center background grid.

Background technique

In the field of printing and typesetting, text typesetting is a very important workflow. At present, in the typesetting process with typesetting software, when text typesetting is performed, after the position of the text block is determined, it is often necessary to place the text block according to the center background. The position of the grid line divides the column.

The current common column division method is to divide the columns evenly according to the width of the text block. This method does not consider information such as the position of the text block, the background grid of the center, and so on. The positions of the background grid and column lines cannot be completely overlapped, and there are some differences between the two. If the text block is required to be divided into columns at a specific position in the background grid of the center, the typesetting personnel need to manually adjust the position of the column lines after the column division. Make the position of the column line of the text block coincide with that of the center background grid line.

It can be seen from the above description that the disadvantages of the existing column division method are: it needs two steps of column division and manual adjustment of the column line to achieve the purpose of column division at a specific position in the background grid of the center of the plate; manually adjusting the position of the column line is time-consuming and laborious. The efficiency of typesetting is reduced; manual operation is affected by the minimum distance of mouse movement, and there are certain errors, which can hardly be eliminated by manual operation.

Contents of the invention

Aiming at the defects existing in the prior art, the object of the present invention is to provide a method for automatically dividing text blocks into columns according to the background grid of the center of the plate. This method can allow typesetting personnel to accurately and quickly place text blocks in the center of the plate through a simple one-step operation. The specific position of the background frame divides the text block into columns.

In order to achieve the above object, the technical solution adopted in the present invention is: a method for automatically dividing text blocks into columns according to the background grid of the core, comprising the following steps:

(1) Determine the text block that needs to be divided into columns, obtain the information of the background grid of the version center, obtain the column width array of each column of the version center, and determine the relative position of the text block and the background grid of the version center;

(2) According to the relative position of the text block and the background grid of the version center, determine the position of the start edge and the end edge of the first column of the text block, and determine the column width of each column of the text block, the start edge of the text block Refers to the left side of the text block frame during horizontal typesetting or the top edge of the text block frame during vertical typesetting. The bottom edge of the outer box;

(3) Carry out column division according to the column width of the text block determined in step (2).

Further, in the step (2), when determining the position of the start edge and the end edge of the first column of the text block, the specific method is as follows: initialization N=-1, N represents the serial number of the current column start edge of the text block in the center column , N=-1 indicates that the starting edge of the current column of the text block is outside the center area, and the information of the background grid of the printing center is obtained to obtain the column width array of the center of the text block, and dStart and dEnd are used to represent the starting edge of the current column of the text block respectively The coordinate value of the coordinate value and the coordinate value of the end edge, the corresponding column width is dEnd-dStart, use hStart and hEnd to represent the coordinate value of the start edge of the core and the coordinate value of the end edge of the core respectively, the coordinate origin of the core area is the origin of the ruler, the positive direction of the X-axis is to the right, and the positive direction of the Y-axis is downward, and then perform the following operations,

1) If the coordinate value of the starting edge of the text block<(hStart-column spacing), N=-1, dStart=the coordinate value of the starting side of the text block, dEnd=hStart-column spacing;

2) If the coordinate value of the starting edge of the text block>=hEnd, N=-1, dStart=the coordinate value of the starting edge of the text block, and the coordinate value of the ending edge of dEnd=the text block;

3) If the first two conditions are not satisfied, then the start edge of the text block is in the center area, then the value of N is determined according to the coordinate value of the start edge of the text block and the coordinate values of the start edge and end edge of each column of the center , wherein, the number of columns of the core background grid>N>=0, dStart=the coordinate value of the start side of the text block, dEnd=the coordinate value of the end side of the Nth column of the core.

Further, in step (2), when determining the column width of each column of the text block, the specific method is as follows:

a. When dStart < the coordinate value of the end edge of the text block, and the current number of columns of the text block < the number of columns in the center of the layout + 2 (because the maximum number of columns that can be divided into a text block with automatic column division = the number of columns in the center of the layout +2), enter the loop;

b. If dStart>=hEnd, or dEnd<=the coordinate value of the starting side of the N+1 column of the core, then the current column is the last column of the text block, dEnd=the coordinate value of the ending side of the text block, and exit the loop;

c. Otherwise, it is not the last column, dEnd = the coordinate value of the end edge of the Nth column of the core, the column width of the current column of the text block = dEnd-dStart;

d. Then, the column number N=N+1, dStart=dEnd+column spacing, update the coordinates of the start side and end side of the Nth column of the version center, and repeat steps a to d.

Further, when determining the column width of the text block:

1) If the starting edge of the text block falls within the area between the ending column line of the Nth column and the starting column line of the N+1th column, then the The part at the starting column line is merged into the first column of the text block, and the part within the space between columns is not divided into a separate column;

2) If the end edge of the text block falls within the area between the end line of column N and the start line of N+1, the part from the end line of column N to the end edge of the text block will be Enter the last column of the text block.

Further, in step (3), after the column widths of all columns in the text block are determined and before column division, if the typesetting direction is reverse horizontal, the column width array is reversed.

The effect of the present invention is that: by adopting the method described in the present invention, typesetting personnel can realize automatic column separation when performing column separation operations on text blocks, without manually adjusting the column width, and can realize accurate and fast layout in the center and background grids. The text blocks are automatically divided into columns at a specific position, and the accuracy and efficiency are greatly improved.

Below in conjunction with accompanying drawing and specific embodiment the present invention will be further described:

As shown in Figure 2, the version core 21 is divided into four columns, namely the 0th column 24, the first column 25, the second column 26 and the third column 27. , 23, the starting side and the ending side of column 1 are shown as 28 and 29 in Fig. 2 respectively. The grid is the background grid of the core, and the background grid of the core fills the entire 21 area of the core.

In this embodiment, first define the meaning of the following technical terms:

The starting edge of the text block: refers to the left side of the outer frame of the text block during horizontal typesetting (X value, 41 in Figure 4), and refers to the top edge of the outer frame of the text block during vertical typesetting (Y value, 61 in Figure 6 ).

The starting edge of the current column of the layout center: refers to the leftmost position of the typesetting area of the current column of the layout center during horizontal typesetting (X value, 28 in Figure 2 indicates the starting edge of the first column), and refers to the layout center of the vertical typesetting The topmost position (Y value) of the layout area of the current column.

The end edge of the current column of the version center: refers to the rightmost position of the typesetting area of the current column of the version center during horizontal typesetting (X value, 29 in Figure 2 indicates the end edge of the first column), and refers to the current column of the version center during vertical typesetting The bottommost position (Y value) of the typesetting area.

End edge of version center: refers to the rightmost position (X value, 23 in Figure 2) of the version center area during horizontal typesetting, and refers to the bottommost position (Y value) of the version center area during vertical typesetting.

In this embodiment, the origin of the coordinates of the core area is the origin of the scale, the positive direction of the X-axis is to the right, and the positive direction of the Y-axis is downward.

As shown in Figure 1, a method for automatically dividing text blocks into columns according to the center background grid includes the following steps:

(1) The first choice is to determine the text block that needs to be divided into columns, obtain the information of the background grid of the version center, obtain the column width array of each column of the version center, and determine the relative position of the text block and the background grid of the version center;

(2) According to the relative position of the text block and the background frame of the center, determine the position of the start edge and the end edge of the first column of the text block, and determine the column width of each column of the text block;

When determining the position of the start side and end side of the first column of the text block, the specific method used in this example is as follows:

Initialize N=-1, N represents the serial number of the initial edge of the current column of the text block in the core column, N=-1 represents the initial edge of the current column of the text block is outside the core area, take the information of the background grid of the print center, and obtain The column width array of each column in the layout center, use dStart and dEnd to represent the coordinates of the start side and end side of the current column of the text block, respectively, the corresponding column width is dEnd-dStart, use hStart and hEnd to represent the layout center respectively The coordinate value of the start side and the coordinate value of the end side of the core, and then perform the following operations,

1) If the coordinate value of the starting edge of the text block<(hStart-column spacing), N=-1, dStart=the coordinate value of the starting side of the text block, dEnd=hStart-column spacing;

2) If the coordinate value of the starting edge of the text block>=hEnd, N=-1, dStart=the coordinate value of the starting edge of the text block, and the coordinate value of the ending edge of dEnd=the text block;

3) If the first two conditions are not satisfied, then the start edge of the text block is in the center area, then the value of N is determined according to the coordinate value of the start edge of the text block and the coordinate values of the start edge and end edge of each column of the center , wherein, the number of columns of the core background grid>N>=0, dStart=the coordinate value of the start side of the text block, dEnd=the coordinate value of the end side of the Nth column of the core.

When determining the column width of each column of the text block, the specific method adopted in the present embodiment is as follows:

a. When dStart < the coordinate value of the end edge of the text block, and the current number of columns of the text block < the number of columns in the center of the page + 2, enter the loop;

b. If dStart>=hEnd, or dEnd<=the coordinate value of the starting side of the N+1 column of the core, then the current column is the last column of the text block, dEnd=the coordinate value of the ending side of the text block, and exit the loop;

c. Otherwise, it is not the last column, dEnd = the coordinate value of the end edge of the Nth column of the core, the column width of the current column of the text block = dEnd-dStart;

d. Then, the column number N=N+1, dStart=dEnd+column spacing, update the coordinates of the start side and end side of the Nth column of the version center, and repeat steps a to d.

As shown in Figure 7 and Figure 8, if the following problems are encountered in the process of determining the column width above, special treatment will be given:

1) If the starting edge of the text block falls in the area between the end column line of the Nth column and the start column line of the N+1 column, as shown in 81 in Figure 8, then start from the text block From the edge to the initial column line of the N+1th column, it is merged into the first column of the text block, and the part within the inter-column space area is not divided into a separate column. In Fig. 8, the starting edge 81 of the text block falls in the area between the terminating column line 83 of the first column and the starting column line 84 of the second column in the center of the version. If the widths of the center columns are all equal, the result shown in Figure 9 will appear. The width of the area 91 in the figure is not enough for the width of one column spacing, and half a column spacing is not allowed in the typesetting. Therefore, the 91 in Figure 9 The area is merged into the first column of the text block, which is the effect in Figure 8. In this way, when the text block is automatically divided into columns in the center area, the maximum width of a column of the text block = the width of the center column + 1 space between the center columns; when the text block is outside the center area, it is not affected by this maximum width. The width is limited.

2) If the ending edge of the text block falls in the area between the ending column line of the Nth column and the N+1th starting column line in the core, as shown in 82 in Figure 8, then the ending column line from the Nth column To the end edge of the text block, merged into the last column of the text block. In FIG. 8 , the end edge 82 of the text block falls within the area between the end line 85 of the third column and the start line 86 of the fourth column in the core. For comparison before and after merging, refer to FIGS. 8 and 9 .

(3) Divide into columns according to the column width of the text block determined in step (2). After the column widths of all columns in the text block are determined, if the typesetting direction is reverse horizontal, the column width array is reversed. It remains unchanged for other layout directions. Carry out column division then, the method for column division is identical with existing common column method.

As Fig. 3, Fig. 5, Fig. 7 are the schematic diagrams that do not carry out text block columns according to the background lattice of the version center, Fig. 4, Fig. 6, Fig. 8 are respectively Fig. 3, Fig. 5, Fig. 7 adopting the method according to the present invention according to the version Schematic diagram of the effect after the heart background grid is automatically divided into columns. As shown in Figure 3 and Figure 4, when the core background grid is horizontal, the numbers near the grid row indicate the row number of the core background grid, and the numbers near the grid column indicate the serial number of the core background grid column. In FIG. 4 , 41 represents the starting side of the text block, and 42 represents the ending side of the text block. Fig. 8 is the effect of Fig. 7 after special treatment by the method of the present invention, and Fig. 9 is the effect of Fig. 7 without special treatment by the method of the present invention, and the effect of Fig. 9 will not appear in actual typesetting.

In addition, its scope of application of the column separation method described in the present invention is described as follows:

(1) Only when the typesetting direction of the text block and the typesetting direction of the background grid of the version center are all horizontal or vertical, the automatic column division of the present invention will have an effect; if the background grid of the version center is horizontal row, the text block is vertical, or the center background grid is vertical, and the text block is horizontal, then the text block has only one column. When the typesetting of the text block is adjusted to be consistent with the typesetting direction of the center background frame, the effect of automatic column division according to the method of the present invention can still be obtained.

(2) Only when there is an overlapping area between the text block and the core, the automatic column division of the present invention is effective; if there is no overlapping area between the text block and the core, then the text block is a column. After adjusting the text block or the center of the page so that there is an overlapping area between them, the effect of automatic column division according to the method of the present invention can still be obtained.

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.
