The names of messages or information interacted between the various devices in the embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of such messages or information.
Referring to FIG. 1, a flow 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:
step 101, when the execution of the target rendering sub-task in the target queue is finished, it is determined whether to continue to execute the first processing task to the target queue.
In this embodiment, the electronic device executing the document rendering method may execute the target rendering sub-task in the target queue.
The above-described target queue may be established in the following manner. Firstly, the rendering tasks of the document to be displayed in the portable document format can be divided, so that a plurality of rendering subtasks are obtained. The resulting plurality of rendering sub-tasks may then be used as queue elements to build a target queue. The target queue may be pre-established by the electronic device that performs the document rendering method, or may be pre-established by a server that is communicatively connected to the electronic device that performs 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 sub-task may correspond to a rendering task of a plurality of pages in the document to be displayed, i.e., the rendering sub-task may be a task of rendering a plurality of pages in the document to be displayed. At this time, by executing a certain rendering sub-task, rendering of a plurality of pages in the document to be displayed can be achieved. Alternatively, the rendering subtask may correspond to a task of rendering a single page in the document to be displayed, i.e., the rendering subtask may be a task of rendering a single page in the document to be displayed. At this time, by executing a certain rendering sub-task, rendering of a single page in the document to be displayed can be achieved.
The target rendering subtask may be a rendering subtask specified in advance in the target queue, or may be any rendering subtask in the target queue.
It will be appreciated that by executing the target rendering sub-task, the electronic device executing the document rendering method may complete rendering of the page indicated by the target rendering sub-task.
In this embodiment, when the execution of the target rendering sub-task 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 a rendering sub-task in the target queue.
In some application scenarios, if there is an unexecuted rendering sub-task in the target queue, when the execution of the target rendering sub-task ends, the electronic device executing the document rendering method may determine to continue to execute the first processing task of the target queue. If the target queue does not have any unexecuted rendering subtasks, the electronic device executing the document rendering method may determine to terminate executing the first processing task of the target queue when executing the target rendering subtask is ended.
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 executing the target rendering subtask is finished, or may determine whether to continue to execute the first processing task of the target queue in the process of executing the target rendering subtask.
Step 102, in response to determining to continue executing the first processing task on the target queue, obtaining a next-order rendering sub-task of the target rendering sub-task from the target queue, and executing the obtained rendering sub-task.
In this embodiment, in response to determining to continue to execute the first processing task on the target queue, the electronic device executing the document rendering method may acquire a rendering sub-task of a next order of the target rendering sub-task from the target queue, and execute the acquired rendering sub-task.
In practice, rendering sub-tasks in the target queue may be arranged according to the rank of the indicated page in the document to be displayed. For example, page A has a rank of 2 in the document to be displayed, then the rendering sub-task of page A has a rank of 2 in the target queue.
It should be appreciated that by executing the next-order rendering sub-task, the electronic device executing the document rendering method may complete the rendering of the page indicated by the next-order rendering sub-task.
Referring to fig. 2, there is shown one application scenario of a document rendering method according to an embodiment of the present disclosure. As shown in fig. 2, when the execution of the target rendering sub-task 2021 in the target queue 202 ends, the terminal device 201 may determine whether there is an unexecuted rendering sub-task in the target queue 202. If there are unexecuted rendering sub-tasks in the target queue 202, the terminal device 201 may determine to continue to execute the first processing task to the target queue 202. Further, the terminal apparatus 201 may acquire a rendering sub-task 2022 of the next bit of the target rendering sub-task 2021 from the target queue 202, and execute the rendering sub-task 2022.
In this embodiment, when the execution of the target rendering subtask in the target queue is ended, it may be determined whether to continue to execute the first processing task on the target queue, and on the premise of determining to continue to execute the first processing task on the target queue, a rendering subtask of a next order of the target rendering subtask is selected from the target queue, and the acquired rendering subtask is executed, so that the rendering flexibility of the document to be displayed is improved. 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.
With continued reference to fig. 3, a flow 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:
step 301, determining whether a second processing task exists when execution of the target rendering sub-task in the execution target queue is ended.
In this embodiment, when the execution of the target rendering sub-task in the target queue ends, the electronic device executing the document rendering method may determine whether or not the second processing task exists.
The second processing task may be a task that processes an operation performed by the user. Thus, by executing the second processing task, processing of the operation performed by the user can be achieved.
The first processing task of the target queue is a target priority. The second processing task has a higher priority 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 is present, it is determined to abort execution of the first processing task on the target queue and execute the second processing task, step 302.
In this 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 will be understood that, after the execution of the target rendering sub-task ends, if there is a task that processes an operation performed by the user, the electronic device that executes the document rendering method may suspend execution of the rendering sub-task in the target queue, and then process the operation performed by the user.
Step 303, in response to determining to continue executing the first processing task on the target queue, obtaining a rendering sub-task of a next order of the target rendering sub-task from the target queue, and executing the obtained rendering sub-task.
The above step 303 may be performed in a similar manner to the step 102 in the embodiment shown in fig. 1, and the above description of the step 102 also applies to the step 303, which is not repeated herein.
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 alternative implementations, the predefined operations described above may include at least one of: copy operation, page zoom operation, and page flip operation.
The above-described copy operation may be an operation in which the user copies content from a document to be displayed.
The above page scaling operation may be an operation in which the user enlarges or reduces the page size of the document to be displayed.
The stay page of the above page turning operation may be a page that the user finally stays when turning 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 alternative implementations, the electronic device executing the document rendering method may update the content of the rendering subtasks in the target queue according to the scaling factor of the page scaling operation.
In practice, the rendering subtask may contain the rendering size of the indicated page. Here, the rendering size may be a size that renders the page.
Specifically, the electronic device executing the document rendering method may determine a rendering size of the document to be displayed after scaling according to the scaling coefficient of the scaling 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 performing 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 alternative implementations, after updating the content of the rendering subtask in the target queue, the pages 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 alternative implementations, the electronic device executing the document rendering method may adjust the order of rendering sub-tasks in the target queue according to the stay page of the page turning operation.
Specifically, after determining a stay page of a page turning operation, an electronic device executing the document rendering method may adjust rendering sub-tasks of the stay page to an order of priority execution in a target queue.
In practice, after the user performs the page turning operation, the electronic device performing the document rendering method may determine to suspend the first processing task on the target queue, and further adjust the order of the rendering subtasks in the target queue.
In these alternative implementations, after the rendering sub-tasks of the stay pages are adjusted to the order of priority execution, priority execution of the rendering sub-tasks of the stay pages may be achieved, thereby achieving priority rendering of the stay pages.
In this embodiment, the priority of the second processing task is higher than the priority of the first processing task. On the premise that the second processing task is determined to exist, the execution of the first processing task on the target queue is stopped, and the second processing task is executed. That is, when there is a task to process an operation performed by the user, rendering of the document to be displayed may be suspended, and the operation performed by the user is preferentially processed. On the one hand, compared with the case that the operation executed by the user is processed after the document to be displayed is rendered, the time for responding to the operation executed by the user can be shortened. On the other hand, compared with the process of the operation executed by the user while rendering the document to be displayed, the method can avoid the clamping caused by simultaneously processing too many tasks.
With further reference to fig. 4, as an implementation of the method shown in the foregoing figures, the present disclosure provides an embodiment of a document rendering apparatus, which corresponds to the method embodiment 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 determining unit 401 and an executing unit 402. Wherein the determining unit 401 may be configured to: when the execution of the target rendering sub-task in the target queue ends, it is determined whether to continue to execute the first processing task to the target queue. The target queue is established by: dividing rendering tasks of a document to be displayed in a portable document format to obtain a plurality of rendering subtasks, and establishing a target queue by taking the plurality of rendering subtasks as queue elements. The execution unit 402 may be configured to: in response to determining to continue executing the first processing task on the target queue, a next rendering sub-task of the target rendering sub-task is obtained from the target queue, and the obtained rendering sub-task is executed.
In this embodiment, the specific processes of the determining unit 401 and the executing unit 402 of the document rendering device and the technical effects brought by them may refer to the descriptions related to the steps 101 and 102 in the corresponding embodiment of fig. 1, and are not repeated here.
In some alternative implementations, the first processing task of the target queue is the target priority. The determining unit 401 may further be configured to: determining whether a second processing task exists, wherein the priority of the second processing task is higher than the target priority; in response to determining that the second processing task is present, 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 alternative implementations, the predefined operation includes at least one of: copy operation, page zoom operation, and page flip operation.
In some alternative 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 subtasks in the target queue according to the scaling coefficient of the page scaling operation.
In some alternative 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 rendering subtasks in the target queue according to the stay page of the page turning operation.
In some alternative implementations, the render subtasks correspond to tasks that render a single page.
