Referring to FIG. 1, a flow diagram of one embodiment of a document rendering method according to the present disclosure is shown. The document rendering method as shown in fig. 1 includes the steps of:
In the present embodiment, an electronic device that executes a document rendering method may execute a target rendering subtask in a target queue.
The above-described target queue may be established in the following manner. Firstly, the rendering tasks of the to-be-displayed document in the portable document format can be divided to obtain a plurality of rendering subtasks. The resulting plurality of rendering subtasks may then be used as queue elements to establish a target queue. It should be noted that the target queue may be pre-established by the electronic device executing the document rendering method, or may be pre-established by a server in communication connection with the electronic device executing the document rendering method.
The rendering task of the document to be displayed may be a task of rendering the document to be displayed.
The rendering subtask may correspond to a rendering task of a plurality of pages in the document to be displayed, that is, the rendering subtask may be a task of rendering the plurality of pages in the document to be displayed. At this time, by executing a certain rendering subtask, rendering of multiple pages in the document to be displayed can be realized. Optionally, the rendering sub-task may correspond to a task of rendering a single page in the document to be displayed, that is, the rendering sub-task may be a task of rendering a single page in the document to be displayed. At this time, by executing a certain rendering subtask, the rendering of a single page in the document to be displayed can be realized.
The target rendering subtask may be a pre-specified rendering subtask in the target queue, or may be any rendering subtask in the target queue.
It is appreciated that by executing the target rendering subtask, the electronic device executing the document rendering method may complete rendering of the page indicated by the target rendering subtask.
In the present embodiment, when the execution of the target rendering subtask ends, the electronic device executing the document rendering method may determine whether to continue to execute the first processing task of the target queue.
The first processing task may be a task that processes rendering subtasks in the target queue.
In some application scenarios, if there are rendering subtasks that have not been executed in the target queue, when the execution of the target rendering subtasks is finished, the electronic device that executes the document rendering method may determine to continue to execute the first processing task of the target queue. If there is no unexecuted rendering subtask in the target queue, when the execution of the target rendering subtask is finished, the electronic device executing the document rendering method may determine to terminate the execution of the first processing task of the target queue.
In practice, the electronic device executing the document rendering method may further determine whether to continue to execute the first processing task of the target queue after the end of executing the target rendering subtask, or may determine whether to continue to execute the first processing task of the target queue during the execution of the target rendering subtask.
In this embodiment, in response to determining to continue to execute the first processing task to the target queue, the electronic device executing the document rendering method may acquire a rendering subtask of a next order of the target rendering subtask from the target queue and execute the acquired rendering subtask.
In practice, the rendering subtasks in the target queue may be arranged according to the indicated page's rank in the document to be displayed. For example, page A has a rank of 2 in the document to be displayed, and then the rendering subtask for page A has a rank of 2 in the target queue.
It should be appreciated that by executing the rendering subtask of the next order, the electronic device executing the document rendering method may complete the rendering of the page indicated by the rendering subtask of the next order.
Referring to fig. 2, an application scenario of a document rendering method according to an embodiment of the present disclosure is shown. As shown in fig. 2, when executing the target rendering subtask 2021 in the target queue 202 ends, the terminal device 201 may determine whether there is an unexecuted rendering subtask in the target queue 202. If there are rendering subtasks in the target queue 202 that have not been executed, the terminal device 201 may determine to continue executing the first processing task for the target queue 202. Further, the terminal device 201 may acquire the rendering subtask 2022 of the next order of the target rendering subtask 2021 from the target queue 202, and execute the rendering subtask 2022.
In this embodiment, when the execution of the target rendering subtasks in the target queue is finished, it may be determined whether to continue to execute the first processing task of the target queue, and on the premise that it is determined that the execution of the first processing task of the target queue is continued, a rendering subtask of a next level of the target rendering subtask is selected from the target queue, and the obtained rendering subtask is executed, thereby improving the rendering flexibility of the document to be displayed. In addition, the rendering of the document to be displayed can be realized on the basis that the rendering task of the document to be displayed is divided into a plurality of rendering subtasks by executing the rendering subtasks in the target queue and rendering the document to be displayed.
Continuing to refer to FIG. 3, a flow diagram of yet another embodiment of a document rendering method according to the present disclosure is shown. As shown in fig. 3, the document rendering method includes the steps of:
In the present embodiment, when the execution of the target rendering subtask in the target queue ends, the electronic device executing the document rendering method may determine whether the second processing task exists.
The second processing task may be a task for processing an operation performed by the user. Thus, by executing the second processing task, processing of the operation performed by the user can be realized.
The first processing task of the target queue is a target priority. The priority of the second processing task is higher than the target priority. That is, the priority of the second processing task is higher than the priority of the first processing task.
In response to determining that the second processing task exists, determining to suspend execution of the first processing task to the target queue and executing the second processing task, step 302.
In the present embodiment, in response to determining that the second processing task exists, the electronic device executing the document rendering method may determine to suspend execution of the first processing task to the target queue and execute the second processing task.
It is understood that after the execution of the target rendering subtask is finished, if there is a task for processing an operation executed by a user, the electronic device executing the document rendering method may stop executing the rendering subtask in the target queue, and may process the operation executed by the user instead.
The above step 303 may be performed in a manner similar to that of the step 102 in the embodiment shown in fig. 1, and the above description for the step 102 also applies to the step 303, which is not described herein again.
In some alternative implementations, the second processing task is established in response to detecting the predefined operation. That is, after the predefined operation is detected, the second processing task is re-established.
In some optional implementations, the predefined operation may include at least one of: a copy operation, a page zoom operation, and a page flip operation.
The copy operation may be an operation in which the user copies content from the document to be displayed.
The page zoom operation described above may be an operation in which the user enlarges or reduces the page size of the document to be displayed.
The page to be stopped in the page turning operation may be a page to be finally stopped when the user turns the document to be displayed. In general, a stay page of a page turning operation may be regarded as a page that a user wants to view preferentially. .
In some optional implementations, the electronic device executing the document rendering method may update the content of the rendering subtasks in the target queue according to a scaling factor of the page scaling operation.
In practice, the rendered size of the indicated page may be included in the render subtask. Here, the rendering size may be a size at which the page is rendered.
Specifically, the electronic device executing the document rendering method may determine the rendering size of the document to be displayed after zooming according to the zooming coefficient of the zooming operation, and further, may update the rendering size included in the rendering subtask in the target queue.
In practice, after the user performs the zoom operation, the electronic device executing the document rendering method may further update the content of the rendering subtask in the target queue after determining to suspend the first processing task to the target queue.
In these optional implementation manners, after the content of the rendering subtask in the target queue is updated, the page in the document to be displayed may be rendered according to the scaled rendering size by further executing the rendering subtask in the target queue.
In some optional implementations, the electronic device executing the document rendering method may adjust an order of the rendering subtasks in the target queue according to a stop page of the page turning operation.
Specifically, after determining the stop page of the page turning operation, the electronic device executing the document rendering method may adjust the rendering subtasks of the stop page to the order of priority execution in the target queue.
In practice, after the user performs the page turning operation, the electronic device executing the document rendering method may determine to terminate the first processing task of the target queue, and further adjust the order of the rendering subtasks in the target queue.
In these optional implementation manners, after the rendering subtasks of the stop pages are adjusted to the order of preferential execution, the rendering subtasks of the stop pages can be preferentially executed, and then the preferential rendering of the stop pages is realized.
In this embodiment, the priority of the second processing task is higher than the priority of the first processing task. On a precondition that the second processing task is determined to exist, execution of the first processing task to the target queue is suspended, and the second processing task is executed instead. That is, when there is a task of processing an operation performed by the user, rendering of the document to be displayed may be suspended, and the operation performed by the user may be preferentially processed. On one hand, compared with the method that the operation executed by the user is processed after the rendering of the document to be displayed is completed, the time for responding to the operation executed by the user can be shortened. On the other hand, compared with the method that the operation executed by the user is processed while the document to be displayed is rendered, the jam caused by excessive tasks being processed at the same time can be avoided.
With further reference to fig. 4, as an implementation of the method shown in the above figures, the present disclosure provides an embodiment of a document rendering apparatus, which corresponds to the embodiment of the method shown in fig. 1, and which is particularly applicable to various electronic devices.
As shown in fig. 4, the document rendering apparatus of the present embodiment includes: a determination unit 401 and an execution unit 402.

The target queue is built up by: the method comprises the steps of dividing rendering tasks of a to-be-displayed document in a portable document format to obtain a plurality of rendering subtasks, and establishing a target queue by taking the rendering subtasks as queue elements. The execution unit 402 may be to: in response to determining to continue executing the first processing task to the target queue, a rendering subtask of a next order of the target rendering subtask is obtained from the target queue, and the obtained rendering subtask is executed.
In this embodiment, the specific processing of the determining unit 401 and the executing unit 402 of the document rendering apparatus and the technical effects thereof can refer to the related descriptions of step 101 and step 102 in the corresponding embodiment of fig. 1, which are not repeated herein.
In some alternative implementations, the first processing task of the queue is a target priority. The determining unit 401 may be further configured to: determining whether a second processing task exists, wherein the second processing task has a priority higher than the target priority; in response to determining that the second processing task exists, determining to suspend execution of the first processing task to the target queue and executing the second processing task.
In some alternative implementations, the second processing task is established in response to detecting the predefined operation.
In some optional implementations, the predefined operation includes at least one of: a copy operation, a page zoom operation, and a page flip operation.
In some optional implementations, the document rendering apparatus may further include a first processing unit (not shown in the figure). Wherein the first processing unit may be configured to: and updating the content of the rendering subtask in the target queue according to the scaling coefficient of the page scaling operation.
In some optional implementations, the document rendering apparatus may further include a second processing unit (not shown in the figure). Wherein the second processing unit may be configured to: and adjusting the sequence of the rendering subtasks in the target queue according to the stop page of the page turning operation.
In some alternative implementations, the render subtasks correspond to tasks that render a single page.
