For the diagram item structure of the first diagram item in the diagram to be edited, the first diagram item can be grouped according to the diagram item structure, which means that the first diagram items with the same diagram item structure are divided into a group.

For example, as shown in fig. 6, a first item of diagram item and a second item of diagram item in the diagram to be edited have the same diagram item structure and are then divided into a group, and a third item of diagram item and a fourth item of diagram item have the same diagram item structure and are then divided into a group.

Here the structural matrix is equivalent to the discrete coordinates of the second shape in the first pictorial item.

It should be noted that, here, the first illustration items are in one-to-one correspondence with the structure matrix, which means that any first illustration item in the illustration to be edited has a corresponding structure matrix, and is determined by the first coordinates of the second shape in the first illustration item, as shown in table 2 below.

First pictorial item	Structural matrix
		Illustration item 1	Structural matrix 1
Illustration item 2	Structural matrix 2

TABLE 2

For the determination of the pictorial item structure of the first pictorial item, reference is made to the method illustrated in FIG. 8. As shown in fig. 8, an implementation flow diagram of another method for determining a structure of a pictorial item provided in an embodiment of the present invention is applied to an electronic device, and specifically includes the following steps:

s801, sorting the X-axis coordinate values in the first coordinates, and sorting the Y-axis coordinate values in the first coordinates.

S802, replacing the X-axis coordinate value with a first sequence value corresponding to the X-axis coordinate value, and replacing the Y-axis coordinate value with a second sequence value corresponding to the Y-axis coordinate value to obtain a matrix coordinate of the first coordinate.

S803, selecting a maximum first sequential value from the first sequential values, and selecting a maximum second sequential value from the second sequential values.

And S804, constructing an empty matrix of M x N according to the maximum first sequence value and the maximum second sequence value, wherein N comprises the maximum first sequence value, and M comprises the maximum second sequence value.

And S805, determining the shape serial number of the second shape corresponding to the first coordinate in the first graphic item.

S806, replacing matrix elements in the empty matrix corresponding to the matrix coordinates of the first coordinates with shape serial numbers to obtain a structural matrix corresponding to the first diagram item.

In the embodiment of the invention, for a first coordinate of a second shape in a diagram to be edited and illustrated first diagram item, the X-axis coordinate values in the first coordinate are sequenced, the Y-axis coordinate values in the first coordinate are sequenced, the X-axis coordinate values are replaced by first sequence values corresponding to the X-axis coordinate values, and the Y-axis coordinate values are replaced by second sequence values corresponding to the Y-axis coordinate values, so that the matrix coordinate of the first coordinate is obtained. Then, the maximum first sequence value is selected from the first sequence values, the maximum second sequence value is selected from the second sequence values, an M-N empty matrix is constructed according to the maximum first sequence value and the maximum second sequence value, N comprises the maximum first sequence value, M comprises the maximum second sequence value, the shape serial number of the second shape corresponding to the first coordinate in the first representation item is determined (the shape serial number is marked in the process of identifying the shape in the first representation item), the matrix elements in the empty matrix corresponding to the matrix coordinate of the first coordinate are replaced by the shape serial numbers, and the structural matrix corresponding to the first representation item is obtained.

It should be noted that, the sorting of the X-axis coordinate value and the Y-axis coordinate value is not an exact sorting of numerical values, but a sorting with a little error, that is, a comparison within a certain threshold range, for example, X1 and X2, and if the difference between X1 and X2 is within the threshold range, they are considered to be in the same order, that is, the sequential values are the same. Further, for an empty matrix of M × N, it means that each element initial value in the matrix of M × N is 0, and the shape number is unique in the first drawing item.

For example, taking the illustration item 1 in the above table 1 as an example, regarding the upper left vertex coordinates (X1, Y1) of the second shape "01" in the illustration item 1, the upper left vertex coordinates (X2, Y2) of the second shape "lesson review" in the illustration item 1, the X-axis coordinate values of the two upper left vertex coordinates are sorted, and the Y-axis coordinate values of the two upper left vertex coordinates are sorted, the sorting result of the X-axis coordinate values is X1, X2, the sorting result of the Y-axis coordinate values is Y1, Y2, where the first sequential value of X1 in the sorting result of the X-axis coordinate values is 1, where the first sequential value of X2 in the sorting result of the X-axis coordinate values is 2, where the second sequential value of Y1 in the sorting result of the Y-axis coordinate values is 1, where the second sequential value of Y2 in the sorting result of the Y-axis coordinate values is 1, then the X-axis coordinate values in the above-mentioned left upper vertex coordinates (X1, Y1) and left upper vertex coordinates (X2, Y2) are replaced with the first sequential values corresponding to the X-axis coordinate values, and the Y-axis coordinate values in the above-mentioned left upper vertex coordinates (X1, Y1) and left upper vertex coordinates (X2, Y2) are replaced with the second sequential values corresponding to the Y-axis coordinate values, where the above-mentioned left upper vertex coordinates (X1, Y1) can be transformed into (1, 1), the above-mentioned left upper vertex coordinates (X2, Y2) can be transformed into (2, 1), and where (1, 1), (2, 1) are matrix coordinates.

Then, the maximum first sequence value is selected from the first sequence values, where the maximum first sequence value is 2, the maximum second sequence value is selected from the second sequence values, where the maximum second sequence value is 1, a 1 × 2 empty matrix is constructed according to the maximum first sequence value and the maximum second sequence value, the shape number 1 of the second shape "01" corresponding to the top left vertex coordinate (x 1, y 1) in the illustration item 1 is determined, the shape number 2 of the second shape "top course" corresponding to the top left vertex coordinate (x 2, y 2) in the illustration item 1 is determined, the matrix element (i.e., the matrix element in the 1 st row and the 1 st column) in the empty matrix corresponding to the matrix coordinate (1, 1) of the top left vertex coordinate (x 1, y 1) is replaced with the shape number 1, the matrix element (i.e., the 1 st row and the column element) in the empty matrix corresponding to the matrix coordinate (2, 1) of the top left vertex coordinate (x 2, y 2) is replaced with the shape number 1, and the matrix element (i.e., the 1 st row and the column element) in the empty matrix corresponding to the shape of the top left vertex coordinate (x 1, y 1) is replaced with the shape matrix element, so that the shape of the empty matrix element, and the shape of the top left vertex coordinate (1, 2) can be obtained as the structure of the structure item as shown in the structure of the figure. Similar processing is performed for the above illustration item 2, illustration item 3 and illustration item 4, so that corresponding structure matrixes can be obtained.

(1 2)。

In the embodiment of the present invention, after the structure matrix corresponding to the first diagram item in the diagram to be edited is obtained, the first diagram item may be grouped by using the structure matrix, that is, the first diagram items having the same structure matrix may be divided into a group.

For example, as shown in table 1, if the configuration matrix of the illustration item 1 is the same as that of the illustration item 2, the illustration item 1 and the illustration item 2 may be divided into one group, and if the configuration matrix of the illustration item 3 is the same as that of the illustration item 4, the illustration item 3 and the illustration item 4 may be divided into one group.

S502, determining a determination strategy of the graph items to be duplicated in the graph to be edited according to the grouping number of the first graph items.

And S503, determining the diagram item to be copied in the diagram to be edited by determining the strategy.

In the embodiment of the invention, for the grouping situation of the first illustration item in the illustration to be edited, the determination policy of the illustration to be duplicated in the illustration to be edited may be determined according to the grouping number of the first illustration item, and then the illustration to be duplicated in the illustration to be edited is determined by the determination policy. Wherein different grouping quantities have different corresponding determination strategies.

Specifically, under the condition that the first diagram items are divided into one group or three groups or more, a first determination strategy of diagram items to be copied in the diagram to be edited is determined, the parity condition of the expansion diagram items in the diagram to be edited is determined based on the first determination strategy, the parity condition represents that the expansion diagram items belong to odd-numbered items or even-numbered items, and the diagram items to be copied in the diagram to be edited are determined in a reverse order according to the parity condition of the expansion diagram items.

Wherein, in the case that the odd-even condition representation extension diagram item belongs to the odd number item, the first diagram item of the first odd number item in the diagram to be edited is determined in the reverse order; determining a first diagram item of a first odd-numbered item as a diagram item to be duplicated in a diagram to be edited; in the case that the parity condition characterizes that the expansion diagram item belongs to an even item, determining a first diagram item of a first even item in the diagram to be edited in a reverse order; and determining the first diagram item of the first even item as a diagram item to be duplicated in the diagram to be edited.

For example, in the case that the parity case characterization extension diagram item belongs to item 5, then diagram item 3 of item 3 in the diagram to be edited may be determined in reverse order, and diagram item 3 of item 3 may be determined as the diagram item to be copied in the diagram to be edited; in the case that the parity condition representation expansion diagram item belongs to the 6 th item, the diagram item 4 of the 4 th item in the diagram to be edited can be determined in a reverse order, and the diagram item 4 of the 4 th item is determined as the diagram item to be copied in the diagram to be edited.

In addition, in the case that the first diagram items are divided into two groups, a second determination strategy of the diagram items to be duplicated in the diagram to be edited is determined, the grouping situation of the first diagram items in the diagram to be edited is determined based on the second determination strategy, and the diagram items to be duplicated in the diagram to be edited are determined through the grouping situation of the first diagram items. For the grouping case where the first illustrated item is divided into two groups, the grouping case can be roughly classified into three types.

For example, the letters a and B represent two different icon structures, the first icon is divided into two groups, and there are three types of grouping: AABB, ABAB, and ABBA, where AABB represents that illustration item 1 and illustration item 2 are divided into a group, illustration item 3 and illustration item 4 are divided into a group, where ABAB represents that illustration item 1 and illustration item 3 are divided into a group, illustration item 2 and illustration item 4 are divided into a group, and where ABBA represents that illustration item 1 and illustration item 4 are divided into a group, and illustration item 2 and illustration item 3 are divided into a group.

In the case that the grouping condition of the first pictorial item belongs to the first-class grouping condition (such as the above AABB), the first pictorial item with the largest pictorial item sequence number in the second group may be determined as the pictorial item to be duplicated in the pictorial representation to be edited, while the pictorial item structure of the first pictorial item with the smallest pictorial item sequence number in the second group is adjusted to be the same as the pictorial item structure of the first pictorial item in the first group.

For example, in the case where the grouping condition of the first illustration item belongs to AABB, then the expanded trend of the illustration to be edited is AAABBB. Here, AABB, i.e. illustration item 1 and illustration item 3, are divided into a first group, and illustration item 2 and illustration item 4 are divided into a second group, at this time, illustration item 4 may be determined as an illustration item to be copied in the illustration to be edited, and the structure of illustration item 3 may be adjusted to the same structure as that of illustration item 1 and illustration item 2, i.e. by dividing illustration item 3 into the first group, so that it may be ensured that the extension trend remains unchanged.

In a case that the grouping situation of the first pictorial item belongs to the second type of grouping situation (such as the aforementioned ABAB), the processing here is similar to the processing of the case that the first pictorial item is divided into a group, and the details of the embodiment of the present invention are not repeated here.

In the case that the grouping condition of the first diagram item belongs to the third type of grouping condition (such as ABBA mentioned above), the diagram item to be duplicated in the diagram to be edited may be determined according to the extension trend of the first diagram item in the diagram to be edited.

For example, in the case where the grouping condition of the first pictorial item belongs to ABBA, then the expanded trend of the pictorial item to be edited is ABBAABBA. Here, ABBA represents that the illustration item 1 and the illustration item 4 are divided into a group, and the illustration item 2 and the illustration item 3 are divided into a group, then according to the extension trend, the illustration item 1 may be determined as a drawing item to be repeated in the illustration to be edited, subsequently, the illustration item 2 may be determined as a drawing item to be repeated in the illustration to be edited, and so on according to the extension trend, so that it may be ensured that the extension trend remains unchanged.

S403, executing the following processing on the to-be-copied illustration item to obtain an edited illustration in the to-be-processed slide.

S404, obtaining the expansion diagram item of the diagram to be edited according to the diagram item to be duplicated.

S405, a first section number text shape in the first shape of the extended illustration item and a second section number text shape in the second shape of the first illustration item to be edited are obtained.

S406, updating the first text in the first section number text shape according to the second text in the second section number text shape.

S407, determining the rest text shapes except the first section number text shape in the first shape, and setting the rest text shapes as placeholder shapes.

In the embodiment of the present invention, for a to-be-copied presentation item, the following processing may be performed on the to-be-copied presentation item to obtain an edited diagram in a to-be-processed slide: the method comprises the steps of obtaining an extended pictorial item of an icon to be edited according to the pictorial item to be copied (namely, copying the pictorial item to be copied to obtain the extended pictorial item of the icon to be edited, pasting the extended pictorial item into the icon to be edited), obtaining a first section number text shape in a first shape of the extended pictorial item and a second section number text shape in a second shape of the first pictorial item to be edited, updating (sequentially) the first text in the first section number text shape according to a second text in the second section number text shape, determining the rest text shapes except the first section number text shape in the first shape, and setting the rest text shapes as placeholder shapes.

It should be noted that, the (orderly) updating of the first text in the first section number text shape according to the second text in the second section number text shape may be incrementally and orderly updating of the first text in the first section number text shape based on the second text in the second section number text shape. For example, if the second text is 03, the first text may be 04, which is not limited in this embodiment of the present invention.

It should be noted that, in the above steps S404 to S407, the case where the section number text shape exists in the to-be-edited drawing is referred to, and in the case where the section number text shape does not exist in the to-be-edited drawing, the following processing is performed on the to-be-copied drawing item to obtain the edited drawing in the to-be-processed slide: copying the to-be-copied representation item to obtain an extended representation item of the to-be-edited representation, pasting the extended representation item into the to-be-edited representation, determining all text shapes in the extended representation item, and setting all text shapes as placeholder shapes, namely, the operation of updating the section number text shapes is not required to be executed.

And S408, carrying out diagram layout on the edited diagram to obtain a target diagram in the slide to be processed.

In the embodiment of the invention, the edited graph can be subjected to graph typesetting to obtain the target graph in the slide to be processed. In order to maintain the visual center balance, all shapes of the diagram need to be zoomed when the diagram item changes, and the zooming can be proportional zooming.

Therefore, the scaling of the third shape in the edited second diagram item can be determined, the second coordinate of the third shape is obtained, wherein the second coordinate includes the vertex coordinate of the circumscribed rectangle of the third shape (the vertex coordinate here refers to the top-left vertex coordinate), the second coordinate, the width and the height of the third shape, and the font size of the third text in the third shape are scaled by using the scaling, and the edited diagram is subjected to diagram layout after scaling processing, so that the target diagram in the slide to be processed is obtained.

Wherein, for the third shapes in the edited second illustration items, it means that all the third shapes in each second illustration item are illustrated after editing. Assuming that the scaling ratio is r, for each third shape, the coordinates of the top left vertex of the circumscribed rectangle of the third shape, the width and height of the third shape, and the font size of the third text in the third shape are scaled with the scaling ratio, as shown below.

The scaled new upper left coordinate of the third shape is represented as Point ((pn.x-p.x) × r + p.x, (pn.y-p.y) × r + p.y), where pn.x is the X coordinate of the upper left vertex coordinate Pn of the circumscribed rectangle of the third shape, pn.y is the Y coordinate of the upper left vertex coordinate Pn of the circumscribed rectangle of the third shape, p.x is the X coordinate of the upper left vertex coordinate P of the circumscribed rectangle of the second pictorial item of the third shape, p.y is the Y coordinate of the upper left vertex coordinate P of the circumscribed rectangle of the second pictorial item of the third shape, and the width and height of the third shape are both multiplied by a coefficient r, i.e., width r, height r, and the font size of the third text of the third shape is also changed to font size r.

Wherein, for the scale of the third shape in the edited second diagram item, the scale can be determined as follows: acquiring the quantity of first pictorial items of a first pictorial item in a pictorial to be edited, and acquiring the quantity of second pictorial items of a second pictorial item in the pictorial after being edited; a quotient of the first number of pictorial items and the second number of pictorial items is obtained, and an arithmetic square root of the quotient is determined as a scale of the third shape in the edited pictorial second item.

Alternatively, the scaling for the third shape in the edited second pictorial item may be determined as follows: obtaining a first area sum of second shapes (all shapes are referred to herein) in a first diagram item to be edited, obtaining a second area sum of third shapes (all shapes are referred to herein) in a second diagram item after editing, obtaining a quotient of the first area sum and the second area sum, and taking an arithmetic square root of the quotient as a scaling ratio of the third shapes in the second diagram item after editing. It should be noted that, the arithmetic square root is only an example, and the embodiment of the present invention does not limit this.

For example, a first number of pictorial items of a first pictorial item in the pictorial item to be edited, i.e., an old pictorial item number, is obtained, a second number of pictorial items of a second pictorial item in the pictorial item after editing, i.e., a new pictorial item number, is obtained, a quotient of the first number of pictorial items and the second number of pictorial items, i.e., the old pictorial item number/the new pictorial item number, is obtained, and an arithmetic square root of the quotient is determined as a scaling r of a third shape in the second pictorial item after editing.

In addition, in the embodiment of the present invention, if the edited diagram belongs to the situation of diagram item extension, the diagram layout is performed on the edited diagram to obtain the target diagram in the slide to be processed, and reference may be made to the diagram layout method shown in fig. 9. As shown in fig. 9, an implementation flow diagram of the graphic typesetting method provided by the embodiment of the present invention is applied to an electronic device, and the method specifically includes the following steps:

s901, identifying the typesetting mode of the first graphic item in the diagram to be edited.

And S902, typesetting the extended graphic items in the edited graphic representation according to the typesetting mode to obtain an initially typesetted graphic representation in the slide to be processed.

In the embodiment of the invention, for the diagram to be edited, namely the original diagram, a certain typesetting rule exists, in order to follow the typesetting rule of the original diagram of the user, the typesetting mode of the first diagram item in the diagram to be edited can be identified, wherein the typesetting mode comprises linear typesetting or radiation typesetting.

For the identified typesetting mode of the first graphic item in the diagram to be edited, the expanded graphic item in the diagram after being edited can be typeset according to the typesetting mode to obtain the initially typesetting diagram in the slide to be processed, so that the typesetting rule of the original diagram of the user can be followed.

For the identification of the linear typesetting, reference may be made to the method shown in fig. 10. As shown in fig. 10, an implementation flow diagram of the method for identifying a linear typesetting provided by the embodiment of the present invention is shown, and the method is applied to an electronic device, and specifically may include the following steps:

s1001, dividing the first graphic item in the graphic to be edited into N groups according to the graphic item serial number of the first graphic item in the graphic to be edited, wherein N =2,3, \8230;, N, N are the same as the number of the first graphic items of the first graphic item.

In the embodiment of the invention, for the diagram to be edited, the first diagram item in the diagram to be edited can be divided into N groups according to the sequence number of the diagram item of the first diagram item in the diagram to be edited, wherein N =2,3, \8230 \ 8230, and N, N are the same as the number of the first diagram items of the first diagram item.

For example, assuming that there are N first pictorial items in the diagram to be edited, the first pictorial item in the diagram to be edited may be divided into 2 groups, 3 groups, \8230 \ N groups, which means that the first pictorial item in the diagram to be edited is divided multiple times, according to the sequence number of the pictorial item of the first pictorial item in the diagram to be edited.

It should be noted that, the above 2 groups represent that the first diagram item in the diagram to be edited is divided into two groups, and the 3 groups represent that the first diagram item in the diagram to be edited is divided into three groups, and so on, which is not limited in this embodiment of the present invention.

In addition, the division is to divide into n groups on average, if there is the remaining first pictorial item after dividing into n groups on average, then it can divide into this n groups in order, for example, the total number of pictorial items is 5 items, and divide into 3 groups, where group 1 includes pictorial item 1 and pictorial item 2, group 2 includes pictorial item 3 and pictorial item 4, and group 3 includes pictorial item 5.

S1002, for n groups of any of the division cases, executes the following processing.

S1003, acquiring third coordinates of the second shape in each group of first graphic items, wherein the third coordinates comprise vertex coordinates of a circumscribed rectangle of the second shape.

S1004, a first difference between the X-axis coordinate values in adjacent third coordinates and a second difference between the Y-axis coordinate values in adjacent third coordinates are determined.

S1005, obtaining fourth coordinates of the first circumscribed rectangle formed by each group of the first pictorial items, wherein the fourth coordinates include vertex coordinates of the first circumscribed rectangle.

S1006, a third difference between the X-axis coordinate values in the adjacent fourth coordinates and a fourth difference between the Y-axis coordinate values in the adjacent fourth coordinates are determined.

S1007, under the condition that the variance of the first difference value and the second difference value is smaller than the variance threshold value and the variance of the third difference value and the fourth difference value is smaller than the variance threshold value, the first graph item in the graph to be edited is determined to be linearly typeset.

In the embodiment of the present invention, for n groups of any of the above-described division cases, the following processing may be performed: acquiring third coordinates of the second shape in each group of the first pictorial item, wherein the third coordinates include vertex coordinates of circumscribed rectangles of the second shape, determining a first difference value between X-axis coordinate values in adjacent (where adjacent refers to the case where adjacent is 1 to 2,2 to 3) third coordinates, and a second difference value between Y-axis coordinate values in adjacent third coordinates, acquiring fourth coordinates of the first circumscribed rectangles formed by the groups of the first pictorial item, wherein the fourth coordinates include vertex coordinates of the first circumscribed rectangle, determining a third difference value between X-axis coordinate values in adjacent fourth coordinates, and a fourth difference value between Y-axis coordinate values in adjacent fourth coordinates, and determining that the first pictorial item in the pictorial item to be edited is linear in the case where a variance between the first difference value and the second difference value is smaller than a variance threshold, and a variance between the third difference value and the fourth difference value is smaller than the variance threshold, as shown in fig. 11. The vertex coordinates here may be, for example, the top left vertex coordinates.

Thus, if the variance between the first difference and the second difference is smaller than the variance threshold, and the variance between the third difference and the fourth difference is smaller than the variance threshold, it indicates that the n groups of the division cases are that the X and Y axis changes of the vertex coordinates of the shapes in each group are isodyne, and the X and Y axis changes of the vertex coordinates (for example, the coordinates of the upper left point) of the circumscribed rectangles between the groups are isodyne, and at this time, it is considered that the condition for linear composition is satisfied, and it can be determined that the first diagram item in the diagram to be edited is linear composition. In the case of dividing the shape into 2 groups, it is possible to consider only whether or not the X-and Y-axis changes of the vertex coordinates of the shapes in the group are equal differences, without considering the groups.

Therefore, typesetting is carried out on the extension graphic items according to the linear typesetting to obtain an initial typesetting graphic representation in the slide to be processed, namely a fifth coordinate is obtained, wherein the fifth coordinate comprises the vertex coordinate of the circumscribed rectangle of the first graphic item in the last group of n groups; adjusting the fifth coordinate according to the first difference and the second difference, or the third difference and the fourth difference to obtain a sixth coordinate; acquiring a seventh coordinate of a second circumscribed rectangle formed by the expanded representation item, wherein the seventh coordinate comprises a vertex coordinate of the second circumscribed rectangle; and adjusting the seventh coordinate to be a sixth coordinate to obtain the initial typesetting diagram in the slide to be processed. The method is characterized in that on the basis of the vertex coordinates of the circumscribed rectangle of the second pictorial item of the last item in the edited diagram, the vertex coordinates of the second circumscribed rectangle formed by the expanded pictorial item can be obtained by adjusting the first difference value and the second difference value or the third difference value and the fourth difference value, and then the adjustment is carried out according to the vertex coordinates.

For example, a fifth coordinate is obtained, where the fifth coordinate includes vertex coordinates (Xn, yn) of a circumscribed rectangle of a first pictorial item in a last group of n groups (e.g., the above 3 groups), and the sixth coordinate is obtained by adjusting the fifth coordinate according to a first difference and a second difference, or a third difference and a fourth difference, where the sixth coordinate is Point (Xn + dx, yn + dy), where dx and dy may be the first difference and the second difference, or the third difference and the fourth difference, so that a seventh coordinate of a second circumscribed rectangle formed by an extended pictorial item may be adjusted to Point (Xn + dx, yn + dy), and an initial layout diagram in a slide to be processed is obtained. Thus, the initial layout graph also meets the linear layout.

It should be noted that, for the extended pictorial item, if it can be divided into n groups of last items (as the above group 3 includes pictorial item 5, the extended pictorial item belongs to pictorial item 6, and it is divided into group 3), which means that the extended pictorial item and the first pictorial item in the n groups of last items belong to the group of internal pictorial items, the fifth coordinate may be the vertex coordinate of the circumscribed rectangle of the first pictorial item of the last item in the n groups of last items, and the fifth coordinate is adjusted according to the first difference and the second difference to obtain the sixth coordinate; acquiring a seventh coordinate of a second circumscribed rectangle formed by the expanded representation item, wherein the seventh coordinate comprises a vertex coordinate of the second circumscribed rectangle; and adjusting the seventh coordinate to be a sixth coordinate to obtain the initial typesetting diagram in the slide to be processed.

Furthermore, for the extended pictorial item, if it is not divided into the n groups of last groups, but can be divided into n +1 groups, meaning that the extended pictorial item and the first pictorial item in the n groups of last groups belong to the inter-group pictorial item (if group 3 includes pictorial item 5, pictorial item 6, and the extended pictorial item belongs to pictorial item 7, which is divided into group 4), the fifth coordinate may be the vertex coordinate of the circumscribed rectangle of the first pictorial item in the n groups of last groups, and at this time, the fifth coordinate is adjusted according to the third difference and the fourth difference to obtain the sixth coordinate; acquiring a seventh coordinate of a second circumscribed rectangle formed by the expanded representation item, wherein the seventh coordinate comprises a vertex coordinate of the second circumscribed rectangle; and adjusting the seventh coordinate to be a sixth coordinate to obtain the initially composed graphic in the slide to be processed.

Further, for the identification of the radial composition, the method shown in fig. 12 may be referred to.

And S1202, determining the perpendicular bisectors of all the straight lines, and judging whether the perpendicular bisectors of all the straight lines intersect.

In the embodiment of the invention, whether the perpendicular bisectors of all the straight lines intersect or not is judged for the perpendicular bisectors of all the straight lines.

It should be noted that, for judging whether the perpendicular bisectors of all the straight lines intersect, intersection points of adjacent perpendicular bisectors may be determined, then for these intersection points, the distance between every two intersection points is calculated, and if the distance is smaller than a set threshold, it may be judged that the perpendicular bisectors of all the straight lines intersect, and the intersection point here may be any one of the intersection points of the adjacent perpendicular bisectors.

And S1203, under the condition that the perpendicular bisectors of all the straight lines intersect, judging whether the distances between the intersection points of the perpendicular bisectors of all the straight lines and all the central points are equal.

In the embodiment of the invention, under the condition that the perpendicular bisectors of all the straight lines intersect, whether the distances between the intersection points of the perpendicular bisectors of all the straight lines and all the center points are equal or not is judged.

It should be noted that, for determining whether the distances between the intersection points of the perpendicular bisectors of all the straight lines and all the center points are equal, the distances between the intersection points and all the center points may be calculated, and it is determined whether the distances are within a certain threshold range, and if so, it may be determined that the distances between the intersection points of the perpendicular bisectors of all the straight lines and all the center points are equal.

S1204, under the condition that the distances between the intersection points and all the central points are equal, determining that the first graphic item in the diagram to be edited is the radial typesetting.

The expanded graphic items are typeset according to the radiation typesetting to obtain a primary layout representation in the slide to be processed, namely an included angle formed by a central point and an intersection point of a circumscribed rectangle of an adjacent first graphic item in the diagram to be edited is obtained; and adjusting the expansion diagram items according to the included angles and the distances to obtain the initially composed diagram in the slide to be processed. Thus, the initial typesetting illustration also meets the requirement of radial typesetting.

And S903, carrying out graphic layout on the primary layout graphic according to the visual gravity center coincidence algorithm to obtain a target graphic in the slide to be processed.

In the embodiment of the invention, visual balance, namely visual gravity balance, is maintained, and in the layout design, the closer the composition is to the balance position of the gravity center, the more harmonious aesthetic feeling is aroused. Therefore, when the graphic item of the graphic is changed, the visual center of gravity of the graphic can be adjusted to the original position.

Based on the method, for the initially laid-out diagram in the slide to be processed, the diagram layout can be carried out on the initially laid-out diagram according to the visual gravity center coincidence algorithm to obtain the target diagram in the slide to be processed, and the coincidence of the visual gravity centers before and after the diagram editing can be ensured, namely the visual gravity centers before and after the diagram editing are unchanged.

The original visual center of gravity of the diagram to be edited can be determined, and then the target visual center of gravity of the initially laid out diagram is adjusted, so that the target visual center of gravity is overlapped with the original visual center of gravity, and the target diagram in the slide to be processed is obtained. The adjustment is automatic, and the visual center of gravity is not changed before and after the diagram editing without human intervention.

For the determination of the original visual barycenter of the diagram to be edited, the following method can be referred to: determining an original center point of a circumscribed rectangle of the diagram to be edited, searching a position extending a preset distance upwards in the vertical direction of the original center point (for example, the preset distance may be 5% of the height of the circumscribed rectangle of the diagram to be edited), and determining the position as an original visual center of gravity of the diagram to be edited.

Wherein, the calculation formula for the visual barycentric coordinate is as follows: Σ (area of each shape in the figure ×. Barycentric coordinates of each shape)/∑ (area of each shape in the figure). Under the condition that the original visual barycenter of the diagram to be edited is known, the area of the fourth shape in the third diagram item of the layout diagram is known, the barycenter coordinate of the fourth shape in the third diagram item of the layout diagram can be deduced through the visual barycenter coordinate calculation formula, and therefore the fourth shape can be adjusted based on the barycenter coordinate, so that the visual barycenter is overlapped before and after diagram editing, namely the visual barycenter is unchanged before and after diagram editing.

Based on the area, the area of the fourth shape in the third graphic item of the initial layout drawing can be determined, and the barycentric coordinate of the fourth shape in the third graphic item is determined according to the original visual barycenter and the area; and adjusting the fourth shape in the third graphic item according to the barycentric coordinates to obtain a target graphic representation in the slide to be processed.

In addition, in the embodiment of the present invention, for the layout of the graphic, there is a certain layout area, where the layout area refers to the maximum range in which the graphic can be laid out in the current slide. For layout areas, the following three rules generally need to be satisfied:

2. The layout area does not contain the non-pictorial text shape, table shape and diagram shape of the slide to be processed, in order to avoid the pictorial conflict with the shape of the text or table or diagram.

3. The background color of the typesetting area does not conflict with the color of the graphic text, and the aim is to avoid the conflict between the color of the graphic text and the background color, so that the situation that the graphic is not clear can be distinguished by naked eyes of a user.

Based on the layout area, the layout area of the drawing in the slide to be processed and a third circumscribed rectangle formed by the target drawing are determined, and the target drawing in the slide to be processed is shown under the condition that the third circumscribed rectangle does not exceed the layout area of the drawing.

It should be noted that, the displaying of the target icon in the slide to be processed here may be displaying the slide to be processed in the center of the current interface, where the slide to be processed contains the icon to be edited, that is, the original slide of the user, displaying the slide to be processed obtained by the present invention on the right side of the interface, and where the slide to be processed contains the target icon, that is, displaying two different slides to be processed on the same interface.
