With the rapid development of writing equipment technology, various intelligent writing equipment is widely applied to daily life of people, people can conveniently write various strokes on the intelligent writing equipment and store the strokes, so that the stored strokes can be reloaded when the strokes need to be checked later. However, when the stored strokes are loaded, the existing intelligent writing device usually adopts a mode of rendering all the stroke contents which need to be displayed on a screen, and under the condition that the stroke contents to be rendered are more, the operation of rendering the strokes is very time-consuming, and the device is easy to be stuck for several seconds, so that the technical problem that the existing writing device consumes a long time for displaying the stored stroke contents is caused.
In order to solve the technical problems, the invention provides a stroke display method, namely, a stroke to be displayed and a picture consistent with the content of the stroke are read, the stroke to be displayed is loaded, and only the screen refreshing processing is waited when the stroke redrawing operation is triggered, so that the actual stroke redrawing operation is saved, the operation processing time required by the actual stroke redrawing is saved, and the writing equipment can simulate the stroke redrawing process only by waiting for a very short time; when the screen is refreshed, the picture containing all the contents of the strokes to be displayed is used for replacing the actual strokes to be displayed for displaying, so that the time required for displaying the strokes is remarkably shortened, and the equivalent effect of displaying the strokes to be displayed is realized, thereby solving the technical problem that the existing writing equipment has longer time consumption for displaying the stored strokes. The stroke display method is applied to stroke display equipment, and is preferably an intelligent book.
Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of a stroke display method.
A first embodiment of the present invention provides a stroke display method, including the steps of:
step S10, reading the strokes to be displayed and the strokes to be displayed pictures containing the strokes to be displayed;
in this embodiment, the present invention can be implemented based on TouchGFX (tai). TouchGFX is an embedded Graphical User Interface (GUI) middleware software that can be used to develop GUI interfaces. The strokes to be displayed are various writing strokes which are written by the user on the writing device and are stored, such as the note content written by the user. The picture of the strokes to be displayed is a picture which is consistent with the content of the strokes to be displayed, namely, the strokes to be displayed are stored in the form of pictures. The stroke picture to be displayed can be synchronously generated when the strokes to be displayed are stored by the writing equipment, and can also be correspondingly generated after the strokes to be displayed are stored by the writing equipment. The writing device can determine the strokes to be displayed which are required to be checked by the current user through the modes of triggering corresponding keys in the device by the user or through network remote control and the like, and read the data of the strokes to be displayed. The strokes to be displayed and the corresponding strokes to be displayed pictures can be searched and read simultaneously by the writing equipment, or the strokes to be displayed and the corresponding strokes to be displayed pictures can be read firstly and then the corresponding strokes to be displayed pictures can be searched and read according to the strokes to be displayed.
Step S20, loading the strokes to be displayed, triggering stroke redrawing logic, and simulating the redrawing process of the strokes to be displayed;
in this embodiment, the stroke redrawing logic is conventional processing logic in a writing device that performs data loading on stored strokes. In addition, it should be noted that each stroke in the writing device exists in the form of a control, and when a current stroke to be displayed that needs to be viewed is loaded, an object corresponding to the stroke to be displayed needs to be created, so as to open up a corresponding memory space for the stroke to be displayed. Specifically, the writing device loads the strokes to be displayed, which need to be checked by the current user, and automatically enters the stroke redrawing logic. When the redrawing function in the stroke redrawing logic is entered, the actual execution step of the redrawing function is skipped, and a success result is directly returned to directly end the stroke redrawing logic. The writing device waits for the screen to perform drawing refreshing and display refreshing twice based on the double-buffer technology, and then the picture of the strokes to be displayed corresponding to the current strokes to be displayed can be displayed on the screen.
And step S30, when the completion of the execution of the stroke redrawing logic is detected, loading and displaying the stroke picture to be displayed so as to display the content of the stroke to be displayed.
In this embodiment, when the writing device detects that the execution of the stroke redrawing logic is completed, a to-be-displayed stroke picture consistent with the content of the to-be-displayed stroke that needs to be viewed by the current user may be displayed on the screen, so that the user may view the content of the to-be-displayed stroke.
As a specific embodiment, if a current user intends to view a note document previously stored in the book, the interface for viewing the history document in the book is entered, and a button for displaying the document content in the interface is clicked. The notebook receives a note display instruction triggered based on the key, finds out note documents required to be checked by the user at present and document screenshots consistent with the document contents according to the instruction. The writing book loads the note document, creates an object of the writing strokes in the note document, and at the moment, can trigger the redrawing logic of the writing strokes in the note document. The writing device enters a redrawing function in the redrawing logic, but does not actually execute the redrawing function, but directly generates a successful return value of the redrawing function to jump out of the stroke redrawing logic, waits for the screen to be refreshed twice, namely switches from the drawing refresh to the display refresh, and then loads and displays the document screenshot consistent with the content of the note document on the screen of the writing book instead of the note document. It should be noted that the screen refreshing time depends on the screen refreshing rate of the writing device, for example, the screen refreshing rate of a book is 60 frames per second, the time for waiting for two screen refreshes, that is, about 1000ms/60 x 2, that is, about 33 ms, in practical application, the whole process only needs to wait for about 10 frames of time to display the document screenshot consistent with the content of the history document that the user needs to view currently on the screen for the user to view, and the jam of the writing device due to too much stroke content is avoided, so that the processing time of the writing device and the waiting time of the user are greatly reduced.
In the embodiment, the strokes to be displayed and the stroke pictures to be displayed containing the strokes to be displayed are read; loading the strokes to be displayed, triggering stroke redrawing logic, and simulating the redrawing process of the strokes to be displayed; and when the completion of the execution of the stroke redrawing logic is detected, loading and displaying the stroke picture to be displayed so as to display the content of the stroke to be displayed. Through the mode, the strokes to be displayed and the pictures consistent with the contents of the strokes are read, the strokes to be displayed are loaded, and the actual stroke redrawing operation is saved when the stroke redrawing operation is triggered, so that the operation processing time required by the actual stroke redrawing is saved, and the writing equipment can simulate and complete the stroke redrawing process only by waiting for a very short time; when the stroke redrawing logic is completed, the picture containing all contents of the strokes to be displayed is used for replacing the actual strokes to be displayed for displaying, so that the time required for displaying the stroke contents is remarkably shortened, and the equivalent effect of displaying the stroke contents to be displayed is realized, thereby solving the technical problem that the existing writing equipment consumes a long time for displaying the stored stroke contents.
Further, referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of a stroke display method.
A second embodiment of the stroke display method of the present invention is proposed based on the first embodiment shown in fig. 2 described above. In the present embodiment, step S20 includes:
step S21, loading the strokes to be displayed, and calling a redrawing function when triggering a stroke redrawing logic;
step S22, generating a successful result of the redrawing function and returning to skip the execution process of the redrawing function based on the successful result, wherein the actual redrawing operation is not performed in the generation process of the successful result;
and step S23, waiting for screen refreshing when the successful result is generated so as to simulate the redrawing process of the strokes to be displayed.
In this embodiment, the writing device loads data of the strokes to be displayed, which the user currently needs to view, and creates an object of the strokes to be displayed, so as to trigger a stroke redrawing logic for redrawing the strokes to be displayed. When the writing device triggers the stroke redrawing logic, the writing device enters the redrawing function corresponding to each stroke. It should be noted that the redrawing function is not actually executed after entering the redrawing function, but a successful result of the redrawing function is directly returned, so as to simulate the redrawing process of the stroke to be displayed in a conventional manner, directly end the stroke redrawing logic, and skip the actual operation process of the stroke redrawing, thereby saving the time for actually redrawing the stroke to be displayed. The writing device enters the stroke redrawing logic, directly returns the successful result of the redrawing function, and waits for two frames of screen refreshing, so that the simulation of the stroke redrawing process can be completed. For example, if the current writing device has a screen refresh rate of 60Hz, i.e. 60 refreshes per second, the time to wait for two frames of screen refresh is about 33 ms.
Further, not shown in the figure, in the present embodiment, the success result includes a first success result, and the step S22 includes:
generating a first successful result of the redrawing function and returning to skip the execution process of the redrawing function based on the first successful result;
step S23 includes:
and when the first success result is generated, copying the stroke picture to be displayed to a first video memory, and waiting for the first video memory to carry out screen refreshing so as to simulate the redrawing process of the stroke to be displayed.
In this embodiment, the first successful result is a result automatically returned by calling the redrawing function for the first time after triggering the stroke redrawing logic. The video memory, also called a frame buffer, is used for storing rendering data processed or to be extracted by the video card chip. As with the memory of a computer, video memory is the means used to store graphics information to be processed. And the first video memory is used for copying the stroke picture to be displayed after the first screen refreshing is carried out when the redrawing function is called for the first time and a successful result is returned.
Further, not shown in the figure, in this embodiment, the success result includes a second success result, and after the step of copying the to-be-displayed stroke picture to a first display memory and waiting for the first display memory to perform screen refreshing to simulate the redrawing process of the to-be-displayed stroke when the first success result is generated, the method further includes:
calling the redrawing function, generating a second success result of the redrawing function and returning to skip the execution process of the redrawing function based on the second success result;
and when the second success result is generated, copying the stroke picture to be displayed to a second video memory, and waiting for the second video memory to carry out screen refreshing so as to finish stroke redrawing logic.
In this embodiment, a double buffering technique is employed. Double buffering means that an object consistent with a screen drawing area is created in a memory, a graph is firstly drawn on the object in the memory, and the graph on the object is copied to a screen at one time. And the second success result is the result automatically returned by calling the redrawing function for the second time after the first video memory is refreshed. And the second video memory is used for copying the stroke picture to be displayed after the second screen refreshing is carried out when the redrawing function is called for the second time and a successful result is returned. The writing device is based on a double-buffer technology, and can complete the stroke redrawing simulation process of the strokes to be displayed after two refreshes of drawing refreshing and display refreshing are needed, so that the stroke pictures to be displayed, which are consistent with the contents of the strokes to be displayed, are displayed on a screen.
Further, not shown in the figure, in the present embodiment, the step S30 includes:
and when the completion of the execution of the stroke redrawing logic is detected, displaying the stroke picture to be displayed on a screen by using the first video memory and the second video memory copied with the stroke picture to be displayed so as to display the content of the stroke to be displayed.
In this embodiment, when the writing device detects that the current two refreshes, i.e., the drawing refresh and the display refresh, are completed, it may be determined that the stroke redrawing logic is completed, and the to-be-displayed strokes may be loaded and displayed on the screen, so that the user may view the contents of the to-be-displayed strokes.
In the embodiment, the redrawing function is skipped by directly returning the successful execution result in the entering process, so that the process of redrawing the strokes to be displayed in the conventional processing logic can be skipped, and the processing time is saved; waiting for two frames of refreshing time based on a double-buffering technology so as to finish redrawing simulation of the strokes to be displayed; through when the screen refreshes and accomplishes, the copy treats that the stroke picture that shows to the display memory for writing equipment screen can treat to show the stroke picture and show, and then reach the purpose that replaces stroke data with picture data and show same content, and in the user plane, show this process of stroke content and conventional redrawing display flow and do not have the difference on the screen from the instruction that sends stroke demonstration, but the length of waiting time greatly reduces, also be promptly need not to increase user's learning cost, can shorten user's waiting time greatly, thereby user experience has been promoted.
Further, not shown, a third embodiment of the stroke display method of the present invention is proposed based on the first embodiment shown in fig. 2 described above. In this embodiment, before step S10, the method further includes:
when the stroke document recorded with the strokes to be displayed is saved, synchronously generating a document screenshot corresponding to the stroke document so as to take the document screenshot as the stroke picture to be displayed;
associating the stroke document with the document screenshot.
In this embodiment, when a user writes strokes on a writing device and clicks a save button to save the strokes, the writing device records the current written strokes in a stroke document, correspondingly generates a document screenshot containing all the contents of the stroke document, and stores the stroke document and the document screenshot in association, so that when the stroke document is found, the corresponding document screenshot is searched in association.
Further, in the present embodiment, step S10 includes:
when a stroke display instruction is received, determining the stroke document based on the stroke display instruction so as to read the strokes to be displayed;
and searching and reading the document screenshot according to the stroke document association so as to finish reading the stroke image to be displayed.
In this embodiment, a user clicks a key used for viewing document content in a document search interface of a writing device to send a stroke display instruction to the writing device, the writing device searches a stroke document that the user currently needs to view based on the stroke display instruction to read a to-be-displayed stroke in the stroke document, and can search a document screenshot corresponding to the stroke document through association of the currently-searched stroke document.
