The implementation manner of the technical scheme of the application is described in detail below.
Example 1
As shown in fig. 1, a picture layout method of an electronic document may include:
and step 103, when the PDF page is drawn, drawing the picture and the overlapped text line thereof according to the sequence of the first list item and the second list item in the drawing list so that the picture and the overlapped text line thereof are displayed according to the hierarchical relation indicated by the picture operation instruction.
In this embodiment, the information of the picture may include one of the following: attribute information of the picture; coordinate information of the picture. Here, the attribute information of the picture includes information such as width and height when the picture is displayed in the PDF page, and the coordinate information of the picture refers to coordinate information of an area where the picture is displayed in the PDF page. Here, the information of the picture may include other information such as a name, a data length, an actual size, etc. of the picture.
In this embodiment, the drawing list is used for drawing the PDF page in the PDF page display process. One PDF page corresponds to one drawing list, and one drawing list may include a plurality of list items corresponding to all objects in the PDF page, where all objects may include pictures, text lines, and the like in the PDF page, and may include tables, graphics, and the like in the PDF page. One picture may correspond to one list item, one text line may correspond to one list item, the list item of the corresponding picture and the list item of the corresponding text line may represent different types, that is, the list item of the corresponding picture is one type, the list item of the corresponding text line is another type, and each type of list item may adopt its unique representation mode. It will be appreciated that in other implementations, different categories of listings may be represented in the same manner.
In one implementation, one list item in one drawing list may correspond to one picture or one text line of a PDF page, and each list item may include an index for associating the list item with information of the corresponding picture or text line and a drawing number indicating a display order of the corresponding picture or text line. The drawing number may represent the ordering of the list item in the drawing list.
Table 1 below is an example of a drawing list. The drawing list comprises 5 list items, each list item comprises an index and a drawing number, and the drawing number is the ordering of the list items in the drawing list.
| List item name | Index | Drawing numbers |
| List item a | First line of characters | 1 |
| List item B | Picture a | 2 |
| List item C | Second line of text | 3 |
| List item D | Third line of text | 4 |
| List item E | Fourth line of text | 5 |
TABLE 1
In this embodiment, the adjusting the ordering of the first list item and the second list item in the drawing list based on the picture operation instruction may include: and modifying drawing numbers in the first list item and the second list item based on the picture operation instruction, and resetting positions of the first list item and the second list item in the drawing list according to the drawing numbers. Therefore, the positions of the list items can be changed by modifying the drawing numbers, and the ordering of each list item in the drawing list is updated, so that the processing efficiency is high, and errors are not easy to occur.
In one implementation, the adjusting the ordering of the first list item and the second list item in the drawing list based on the picture operation instruction may include: when the picture operation instruction is an upward floating N layer, after the first list item is moved to the last N-1 list items of the second list item, N is an integer not less than 1. Therefore, the picture can cover the front N lines of characters floating on the picture by moving the list item, so that the similar layout requirements of a user on the picture in the PDF document are met.
In another implementation manner, the adjusting the ordering of the first list item and the second list item in the drawing list based on the picture operation instruction may include: and when the picture operation instruction is to move down M layers, moving the first list item to the first M list items of the second list item, wherein M is an integer not smaller than 1. Therefore, by moving the list item, M rows of characters in the back of the character rows originally covered by the picture (namely, the overlapped character rows of the picture) can be displayed, so that the similar layout requirements of users on the picture in the PDF document are met.
In this embodiment, when the PDF page is drawn, drawing the picture and the overlapped text line thereof according to the ordering of the first list item and the second list item in the drawing list may include: traversing the drawing list of the PDF page, and drawing objects of the PDF page one by one according to the ordering of list items in the drawing list, wherein the objects at least comprise the pictures and the overlapped text lines thereof. In this way, corresponding objects are sequentially drawn according to the ordering of list items in the drawing list of the PDF page, so that the display effect of the PDF page meets the requirements of users, and the processing efficiency is higher.
Specific implementations of the present embodiment are described below with reference to examples.
When a user needs to float a certain picture in a PDF page, the processing flow may include:
in practical application, the user may input the picture operation instruction in various manners, for example, select a picture and click a corresponding menu item preset in a menu bar of the PDF document to input the picture operation instruction, or select a picture, trigger a right-key menu through a right-click mouse, and click a menu item "floating up one layer" in the right-key menu. In addition, the input of the picture operation instruction, such as a preset shortcut key, can be realized in other manners.
here, there may be one or more overlapping text lines of a picture, and there may be one or more corresponding second list items.
Here, the process of finding the first list item corresponding to the picture in the drawing list of the current PDF page according to the information of the picture (for example, the coordinate information of the picture) may be: from the first list item to the last list item in the drawing list, traversing in sequence, firstly judging the type of the list item, if the list item is not a picture, searching the next list item, if the list item is a picture, judging whether the coordinate point input by the user is in the range of the picture according to the coordinate of the picture in the document and the width and height of the picture, if the coordinate point input by the user is in the range of the picture, searching successfully, and if the coordinate point input by the user is not in the range, continuing searching the next list item.
specifically, whether the first list item is behind the second list item in the position of the drawing list is judged, if yes, the picture is indicated to be currently located on the top layer, and if not, the picture is indicated to be not currently located on the top layer.
here, if the picture overlaps a plurality of lines of text, that is, there are a plurality of second list items, the search may be sequentially performed according to the order of the list items in the drawing list, and the first list item may be inserted at a position subsequent to the first found second list item. In addition, a second list item may optionally be inserted into the first list item after the second list item, which is not limited herein. Step 207, updating the drawing list of the PDF page to the page data of the current PDF page, and loading the PDF page data into a memory for storage;
here, PDF page data may include, but is not limited to, text, pictures, forms, and the like.
Here, the drawing list of the PDF page may be updated, and each item in the drawing list may be sequentially generated into a corresponding PDF standard format for saving.
And step 208, drawing and displaying the PDF page by traversing the drawing list, and sequentially drawing and displaying the pictures and the overlapped characters according to the ordering of the first list item and the second list item in the drawing list when the PDF page is drawn.
As shown in fig. 3A, 3B, 3C, and 3D, an exemplary diagram of an interface for PDF picture layout change is shown. Fig. 3A is a schematic diagram of an interface before the floating operation, in which the picture in fig. 3A is located at the bottom layer and overlaps with the bottom layer, and the display effect of the interface after the floating one layer is set is shown in fig. 3B, and at this time, the picture covers the first line of characters. The display effect of the interface after the "floating one layer" is set on the basis of fig. 3B or the "floating two layers" is set on the basis of fig. 3A is shown in fig. 3C, and at this time, the first line of characters and the second line of characters are covered by the picture. And so on until the picture is positioned on the top layer, the display effect at the moment is as shown in fig. 3D, and the picture covers all four lines of characters overlapped with the picture. It can be seen that after the user sets the picture to float one layer, the picture will cover the front line of characters floating on the picture. It will be appreciated that if the user sets the picture to float up N layers (N is an integer not less than 1), the picture will obscure the top N lines of text that float on the picture.
As shown in fig. 4, when a user needs to move down a certain picture in a PDF page by one layer, the process flow may include:
in practical applications, the user may input the picture operation instruction in various manners, for example, select a picture and click a corresponding menu item preset in a menu bar of the PDF document to input the picture operation instruction, or select a picture, trigger a right-key menu through a right-click mouse, and click a menu item "move down one layer" in the right-key menu. In addition, the input of the picture operation instruction, such as a preset shortcut key, can be realized in other manners.
here, there may be one or more overlapping text lines of a picture, and there may be one or more corresponding second list items.
specifically, whether the first list item is behind the previous list item of the second list item in the position of the drawing list is judged, if so, the picture is indicated to be currently positioned at the bottom layer, and if not, the picture is indicated to be not currently positioned at the bottom layer.
and 408, drawing and displaying the PDF page by traversing the drawing list, and sequentially drawing and displaying the pictures and the overlapped characters according to the ordering of the first list item and the second list item in the drawing list when the PDF page is drawn.
After the user sets the picture down one layer, after the processing shown in fig. 4, the text of the text line that is originally covered by the picture (i.e., the overlapped text line of the picture) is displayed in the next line. It will be appreciated that if the user sets the picture down by M layers (M is an integer not less than 1), the M rows of text that were later in the text rows originally obscured by the picture (i.e., the overlapping text rows of the picture) will be displayed. The display effect of the move-down operation changes in reverse to the above-described processes of fig. 3A to 3D. Specifically, on the basis of fig. 3D, the fourth line of text is displayed on the picture (not shown) after one layer of the downward movement, on the basis of fig. 3D, the third line of text and the fourth line of text are displayed on the picture (shown in fig. 3C) after two layers of the downward movement, and on the basis of fig. 3D, the second line of text, the third line of text and the fourth line of text are displayed on the picture (shown in fig. 3B) after three layers of the downward movement. And so on, when the last picture is positioned at the bottommost layer, as shown in fig. 3A, all text lines overlapped with the picture are displayed on the picture.
It should be noted that fig. 2 to fig. 4 are all examples, and in practical applications, the present embodiment may be implemented in other manners.
In this embodiment, the hierarchical relationship between the designated picture and the overlapped text line in the PDF document can be changed according to the instruction input by the user, so that the layout relationship between the picture and the overlapped text line meets the user's requirements, thereby meeting the various requirements of the user on the layout of the picture in the PDF document. In the related art, only the top-or bottom-laying operation is supported for the picture, that is, either the picture completely hides the overlapped text lines, or all the overlapped text lines are displayed on the picture (i.e. hide the picture), which often cannot achieve the effect of floating up or down for a single line or several lines of text. In the related art, if a user has similar requirements (for example, floating up or moving down for a single line or several lines of text), the picture needs to be deleted and then added to the corresponding position, and when the position is not in accordance with the requirement when the picture is added, the operation of deleting and then adding for many times may be required, so that the operation is complex and complicated, and the misoperation probability is high. Therefore, the method of the embodiment not only perfects the editing function of the PDF document, but also can greatly simplify the user operation and greatly improve the user experience.
