Detailed Description
In order to make the purpose, technical solution and beneficial effects of the present application more clear and more obvious, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
First, some terms referred to in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.
A terminal: various applications may be installed, and a device capable of displaying an object provided in an installed application may be mobile or fixed. For example, a mobile phone, a reader computer, various wearable devices, a vehicle-mounted device, a Personal Digital Assistant (PDA), a point of sale (POS), or other electronic devices capable of implementing the above functions.
The application comprises the following steps: the application interface of the computer program can be generally provided with a display interface and an interactive interface, wherein the display interface is used for displaying the content of a document page and can edit the document page. The interactive interface is used for receiving instructions of a user, such as page display mode adjustment instructions, applications such as electronic maps and WeChat, and the like, and in this application, applications for processing documents are referred to as document processing applications, such as document processing applications for office use, or common document reading applications. Some applications require a user to install them on the device being used to use them, such as an office document processing application or a reader, and some do not require application installation, such as individual applets in a WeChat. The applet can be used without downloading or installing, and the user can open the application by scanning or searching.
Page layout: the content displayed on the document display interface in the document processing application is used as a typesetting scheme of a page of document.
Document elements: various elements contained in the document, such as words, symbols, pictures, and the like.
Document element display size: the size of the elements displayed on the document display interface, such as the word size of the characters, the length and the width of the pictures and the like.
Display capacity: the size of the page that can be displayed on the display interface of the document page.
The design concept of the embodiment of the present application is described below.
When a user reads or processes a document, the document page display mode of the document is often switched. The document processing application needs to perform page updating and typesetting according to the adjustment instruction of the user, and performs page typesetting adjustment on the document according to the adjustment instruction, so as to display the corresponding document page according to the reading record.
However, in this way, if the reading position of the user is not considered and the specific reading position is adopted for positioning, the content displayed on the document display interface may be shifted too much, which causes difficulty in positioning the position to be read continuously by the user, and even requires the user to turn pages to find the reading position before switching, which reduces the efficiency of processing the document by the user and causes inconvenience to the user.
For example, refer to fig. 1a, which is a diagram illustrating an example of a terminal application interface before font scaling. Fig. 1b is a diagram illustrating an example of a terminal application interface with a font enlarged. The font size is 16 in fig. 1a and 20 in fig. 1 b. After the document processing application has resized the font in the document from 16 to 20, the top line character "… … anyway" in FIG. 1a shifts to the middle of the page in FIG. 1 b. The user needs to look for "… … anyway" in fig. 1b in order to continue reading.
For another example, refer to fig. 1c, which is a diagram illustrating an example of a computer interface before font size reduction. FIG. 1d is a diagram of an example of a computer interface with a reduced font size. After the document processing application has resized the font size in the document from the four-size word shown in FIG. 1c to the five-size word shown in FIG. 1d, the top line character "… … anyway" in FIG. 1c has shifted to the upper side in the page in FIG. 1 d. The user needs to look for "… … anyway" in fig. 1d in order to continue reading.
For another example, refer to fig. 1e, which is a diagram illustrating an example of a reader application interface that pages up and down. FIG. 1f is a diagram illustrating an example of a left-right page turning reader application interface. The document processing application switches the document page in the page up and down direction shown in FIG. 1e to the document page in the page left and right direction shown in FIG. 1 f. The left side of the top row in FIG. 1e, "those bank flowers … …," has shifted to the right side of the top row in FIG. 1f, and the user needs to look for "those bank flowers … …" in FIG. 1f in order to continue reading.
Therefore, a technical solution for controlling document display is urgently needed, which improves the accuracy of positioning and displaying the document content and facilitates the reading of the user when the adjustment instruction of the document page display mode is given.
In view of this, the applicant considers that the document can be page-laid out with the designated position of the target document element as the reference, and the adjusted document page is displayed in a manner of keeping the target document element at the designated position, so as to improve the accuracy of reading position positioning and keep the reading position of the user.
In view of the above analysis and consideration, an embodiment of the present application provides a technical solution for controlling document display, in which a target document element for determining a specified position in a current document page is obtained in response to an adjustment instruction for adjusting a document page display mode; determining document contents to be displayed in the document page after the document page display mode is adjusted in a mode of keeping the target document elements at the designated positions; and displaying the document content to be displayed in the adjusted document page in a mode of keeping the target document element at the specified position.
To further illustrate the technical solutions provided by the embodiments of the present application, the following detailed description is made with reference to the accompanying drawings and the detailed description. Although the embodiments of the present application provide method steps as shown in the following embodiments or figures, more or fewer steps may be included in the method based on conventional or non-inventive efforts. In steps where no necessary causal relationship exists logically, the order of execution of the steps is not limited to that provided by the embodiments of the present application. The method can be executed in sequence or in parallel according to the method shown in the embodiment or the figure when the method is executed in an actual processing procedure or a device.
Referring to fig. 2a, a schematic view of an application scenario of document display control is shown. In the application scenario shown in fig. 2a, the user processes the document through the document processing application of the terminal shown in fig. 2a and inputs an adjustment instruction of the page display mode of the document. And the document processing application typesets the page of the document according to the adjusting instruction by taking the target document element and the designated position where the target document element is located as a reference, and displays the adjusted page of the document.
The adjusting instruction is an instruction for page layout of the document. For example, the adjustment instruction is document element display size adjustment, document page turning direction adjustment, and the like. The adjustment instruction can be input through a key, a touch screen and the like, and can be obtained through the induction of a sensor in the terminal, for example, a user switches the terminal from a horizontal screen to a vertical screen for reading. The terminal obtains an adjusting instruction for switching horizontal screen reading to vertical screen reading through a built-in sensor.
The specified position and the document page currently presented by the document processing application have a specified relative position relationship determination. For example, the designated location is the first character of the document page. The designated position may be a default position or may be set by a user instruction. For example, referring to fig. 2b, which is an exemplary diagram of an application interface for setting a designated location, a user sets the designated location through a key of the application interface for setting the designated location.
In the embodiments of the present application, an application that processes a document is referred to as a document processing application. Alternatively, the document processing may include document reading, document editing, and the like. The document page display mode includes: a document element display size of the document page display and a page turning direction of the document page. The document elements can be characters, symbols, pictures and the like. The page turning direction can be left and right page turning, up and down page turning and the like.
In the embodiment of the application, the designated position and the target document element are used as references, and paging typesetting is performed on all document elements in the document according to the adjusting instruction, so that when the document page display mode is switched, corresponding document content is displayed according to the target document element and the designated position, and a user can directly continue reading the document without turning pages and searching for the reading position after page adjustment.
Referring to fig. 3, a flowchart of an implementation of a document display control method provided in the present application is shown. The method comprises the following specific processes:
step 300: the document processing application responds to an adjusting instruction for adjusting the document page display mode, and obtains a target document element for determining a specified position in the current document page.
Specifically, when step 300 is executed, the user may input an adjustment instruction through a button of the terminal and the touch screen. The terminal can also sense the adjustment instruction of the user according to the arranged sensor. If the sensor of the terminal senses that the terminal is placed on the transverse screen, the adjusting instruction is determined to be the transverse screen display document page, and when the sensor senses that the terminal is placed on the vertical screen, the adjusting instruction is determined to be the vertical screen display document page. The adjusting instruction is used for switching the document page display mode, and is usually an instruction of the document page display mode in which page layout needs to be performed on the document in the switching process, and includes a document element display size adjusting instruction, a document page turning direction adjusting instruction, and the like. The target document element may be one or more characters.
Preferably, the target document element of the specified position includes: setting a first document element of a line in a current document page; or a document element adjacent to a first document element of the current document page; or a document element adjacent to the last document element of the current document page.
In practical application, the designated position may be set correspondingly according to a practical application scene, or may be set to any other position, which is not described herein again. In one embodiment, the document processing application records the set designated location in response to a designated location setting operation entered through an application interface of the document processing.
In one embodiment, when a user performs document processing through a document processing application of a terminal, an adjustment instruction for adjusting a document page display mode is input through an application interface of the document processing application, and the document processing application responds to the adjustment instruction to acquire a target document element for determining a specified position in a current document page.
The document processing may be document reading, document editing, and the like. For example, a user writes a paper through a document processing application. The document is composed of at least one document element, and the document elements in the document are divided in at least one page according to a set display capacity and a corresponding document element display size. The document elements may be text or pictures. The display capacity indicates the size (i.e., dimension) of a document page, which is a page of the content presented in the document display interface, and may be represented by pixels.
Thus, a target document element in the document having a specified relative positional relationship with the displayed document page can be acquired.
Step 301: the document processing application determines a document element display size according to the adjustment instruction.
Specifically, when step 301 is executed, the following two ways may be adopted:
the first mode is as follows: and if the adjusting instruction is an instruction for adjusting the display size of the document element, determining the adjusted display size of the document element of the document page according to the adjusting instruction for the display size of the document element.
Optionally, the document element display size of the document element may be a font size of a text or a size of a picture.
For example, if the font size of the currently displayed text of the document processing application is a four-size character and the adjustment instruction is to adjust the font size of the text to a five-size character, the document processing application determines that the display size of the document element is a five-size character.
The second way is: and if the adjusting instruction is an instruction for adjusting the page turning direction of the document, the document processing application directly acquires the current display size of the document element.
This is because the display size of the document element does not need to be adjusted when the page turning direction is switched, and therefore, the current document element is directly acquired.
For example, the currently displayed font of the document processing application is a four-number character, and the adjustment instruction is to switch the page up and down direction to the page left and right direction, then the document processing application directly determines that the display size of the document element is the four-number character.
Alternatively, the document element display size of the document element may be represented by a specific size value (e.g., the font size of a font) or may be represented by a scale (1.5 times the image magnification). The document element display sizes may also be different for different document elements. For example, the document element display sizes of text and image are different.
Thus, the adjusted display size of the document element can be determined respectively according to different adjusting instructions.
Step 302: and the document processing application determines the document content to be displayed in the document page after the document page display mode is adjusted in a mode of keeping the target document element at the specified position according to the acquired target index of the target document element, the display capacity of the document page and the display size of the document element.
Specifically, when step 302 is executed, the document processing application may adopt the following steps:
s3021: a target index of a target document element and a display capacity of a document page are obtained.
It should be noted that each document element included in the document is provided with a corresponding index.
For example, the document elements in the document are, in order: a is1，a2，a3……am-1，am，am+1……an. The document processing application determines that the target document element is the first document element a of the first line of the document pagemThe target index of the target document element is m.
Thus, the target document element in the document having the specified relative positional relationship with the displayed document page can be acquired, and the target document element is uniquely positioned in the document through the target index.
S3022: according to the target index, the display capacity and the document element display size, a head end index of a first document element and a tail end index of a last document element of the document page are determined while the target document element is still at the designated position.
In one embodiment, if the target document element at the designated position is the first document element of the set row in the current document page, the document processing application directly determines the target index as the head-end index, and sequentially adds the document elements indexed after the target index to the document page according to the display sizes of the document elements until the product of the display sizes of the document elements and the corresponding document elements in the document page is the display capacity, that is, the document page is full, or all the document elements indexed after the target index in the document are added to the document page, that is, the document page is not full, but the document is finished. Finally, the document processing application determines the index of the added last document element as the end index of the last document element of the document page.
In one embodiment, if the target document element at the specified position is the last document element of a page previous to the current document page, the document processing application determines the head end index as the target index plus 1. Then, the document processing application adds the document elements indexed after the head-end index to the document page in sequence until the product of the added document elements and the corresponding document element display size is the display capacity, or all document elements indexed after the head-end index in the document have been added to the document page. Finally, the document processing application determines the index of the added last document element as the end index of the last document element of the document page.
Based on the principle that the head end index and the tail end index are determined for the first document element of the set row in the current document page or the target document element of the designated position is the last document element of the previous page of the current document page according to the target document element of the designated position, the head end index and the tail end index of the document page can be determined when the designated position is any other position, and the description is omitted.
It should be noted that, the document may further include a special character, such as a line feed character, and since the special character is not generally indexed, if the special character exists, the end index and the head index are determined according to the special character, in addition to the target index, the display size of the document element, and the display capacity.
For example, if the target document element at the specified position is the first character of the set line in the current document page, the first line x x a of the document pagem……And x represents a space, the document processing application determines that the target document element is am。
S3023: and determining the document content to be displayed in the document page after the document page display mode is adjusted according to the head index of the first document element and the tail index of the last document element of the document page.
Specifically, the document processing application determines document elements indexed between the head end index and the tail end index and document elements indexed as the head end index and the tail end index as document contents to be displayed in the document page after the document page display mode is adjusted. Wherein, the document content comprises at least one document element.
Further, the document processing application performs page layout on the whole document according to the head end index and the tail end index, and the specific steps are as follows:
and page layout is carried out on each document element in the document, which is indexed before the index at the head end, according to the display capacity and the corresponding display size of the target document element, and page layout is carried out on each document element in the document, which is indexed after the index at the tail end, according to the display capacity and the corresponding display size of the document element.
When page layout is performed on each document element in the document, which is indexed before the head index, according to the display capacity and the display size of the corresponding target document element, the following method can be adopted:
the first mode is as follows: and sequentially typesetting the document elements of the document before the index of the head end according to the display capacity and the display size of the corresponding target document elements and the sequence of the indexes from high to low.
For example, the document elements in the document are, in order: a is1，a2，a3……am-1，am，am+1……an. Index for m as head end. The document processing application will a1，a2，a3……am-1And typesetting from back to front. For example, a1，a2，a3……am-1The composed document has a capacity of 6500px (pixels) and a display capacity of 600px, document elements of the portion from 5900px to 6500px are added to the 11 th page, document elements between 5300px to 5900px are added to the 10 th page, and so on, and finally document elements between 0px to 500px are added to the first page.
Thus, each document element is page-laid from back to front, and a blank may exist in the first page of the laid-out document.
The second way is: and sequentially typesetting the document elements of the document before the index of the head end according to the display capacity and the display size of the corresponding target document elements and the sequence of the indexes from low to high.
For example, the document elements in the document are, in order: a is1，a2，a3……am-1，am，am+1……an. Index for m as head end. The document processing application will a1，a2，a3……am-1Typesetting from front to back. For example, a1，a2，a3……am-1The composed document has a capacity of 6500px (pixels) and a display capacity of 600 px. The document processing application adds document elements between 0px and 600px to the first page, adds document elements of 600px and 1200px parts to page 2, and so on, and finally adds document elements between 6000px and 6500px to page 11.
In this way, each document element is page-laid from front to back, and a margin may exist in the last page after layout.
Step 303: the document processing application displays the document content to be displayed in the adjusted document page in a manner that maintains the target document element in the specified position.
Specifically, when step 303 is executed, the positional relationship between the displayed document page and the target document element is not changed, but remains in the specified relative positional relationship.
For example, referring to fig. 4a, an exemplary diagram of a terminal application interface before font adjustment is shown. Fig. 4b is a diagram illustrating an example of a font-adjusted terminal application interface. The adjustment instruction is to adjust the font size, namely, the font size is adjusted from 16 to 20, and the specified position is the first 4 characters of the first line of the document page. The document processing application determines from figure 4a that the target document element is "anyhow" and, based on "anyhow", resizes the font in the document page to 20, resulting in the document page shown in figure 4b, the first 4 characters of the document page in figure 4b still not being "anyhow".
For another example, refer to fig. 4c, which is a diagram illustrating an example of a reader application interface before the document display interface is adjusted. FIG. 4d is a diagram of an example of a reader application interface with an adjusted document display interface direction. And the adjustment instruction is to switch horizontal screen reading into vertical screen reading, and the specified positions are three characters at the tail of the document page. In FIG. 4c, the document processing application landscape displays the document page with the target document element "pilgrimage". The document processing application updates the document contents of the document page to the document page shown in fig. 4d according to the adjustment instruction. The last three characters of the document page in fig. 4d are still "pilgrimage".
The adjusting instruction is to switch from the up-down page turning direction to the left-right page turning direction. If the first 4 characters of the first line of the corresponding 10 th page are also determined to be 'any character', the document page is not adjusted, and the document page shown in fig. 4d is directly displayed.
Further, if the adjustment instruction is to switch from the left-right page turning direction to the up-down page turning direction, and the page layout does not need to be performed again, step 301 and step 302 may not be executed, and the container of the target document element is directly scrolled to the designated position after switching from the left-right page turning direction to the up-down page turning direction, so that other document elements of the document also sequentially perform corresponding movements.
This is because the document processing application will typically jump to the first page of the presentation document after switching from the left-to-right page-turning direction to the up-to-down page-turning direction. In the embodiment of the application, after the document processing application is switched from the left-right page turning direction to the up-down page turning direction, the container of the target document element is directly rolled to the specified position, so that the reading position of a user is kept.
Further, if the adjustment instruction is to switch from the up-down page turning direction to the left-right page turning direction, and the position relationship between the target document element and the corresponding page of the document page layout is also the specified relative position relationship, the document page is not adjusted, that is, the document page does not need to be page-rearranged.
For example, amFor the first line character of the document page, i.e. the first character of the document display interface, and amIs the first character of page 9 of the document, am-1On page 8, after the page is switched from the up-down page turning direction to the left-right page turning direction, the reading position can be kept unchanged without updating the document page.
In the embodiment of the application, the designated position of the target document element is taken as a reference, page typesetting is carried out on the document, and the adjusted document page is displayed in a mode of keeping the target document element at the designated position, so that when the document page display mode is adjusted, the accuracy of positioning and displaying the document content is improved, the current reading position of a user is kept as much as possible in the content displayed by the adjusted document page, and the user can conveniently continue reading.
Based on the same inventive concept, the embodiment of the application also provides a document display control device, and as the principle of solving the problems of the device and the equipment is similar to that of a document display control method, the implementation of the device can be referred to the implementation of the method, and repeated details are not repeated.
