Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic diagram of an interface for drawing and erasing ink during playback of a presentation in the prior art. As shown in fig. 1(a), when the presentation is played, the right button pops up the function menu, and the "pen" or the "highlighter" is selected in the "pointer option", so that the corresponding ink can be drawn, and a certain part of the content in the presentation can be highlighted conveniently, thereby attracting the attention of the audience. If the drawn ink is to be modified, as shown in fig. 1(b), an "eraser" is selected from a function menu popped up after clicking the right button, then the ink to be erased is selected again, or "all ink on the slide is erased", and all the drawn ink is erased at one time. It can be seen that, in the prior art, when erasing the ink drawn while playing the presentation, if the "eraser" function is selected, the operation is complicated, and if "erasing all the ink on the slide" is selected, since the erased ink cannot be recovered, data loss is easily caused, which brings inconvenience to the user.
Therefore, the embodiment of the invention provides an ink canceling method, which can avoid data loss while simplifying operation, facilitate the user to edit the ink, and improve the user experience.
The ink canceling method provided by the embodiment of the present invention will be generally described below.
In one implementation, the ink canceling method includes:
after opening a demonstration manuscript display page, establishing a blank operation record; pointing a preset ink pointer to a blank operation record;
monitoring the operation of a user;
when the ink editing operation is monitored, adding an operation record corresponding to the current ink editing operation after the operation record pointed by the current ink pointer;
pointing a preset ink pointer to the currently added operation record;
when the operation cancellation is monitored, judging whether the operation record pointed by the ink pointer currently is a blank operation record; if not, pointing the ink pointer to the last operation record of the currently pointed operation record;
and refreshing the display page, and displaying the operation record pointed by the ink pointer and the ink corresponding to the previous operation record.
According to the ink mark canceling method provided by the embodiment of the invention, each ink mark editing operation is recorded, the pointing direction of the ink mark pointer is changed according to the canceling operation of the user, the operation record pointed by the ink mark pointer and the ink mark corresponding to the previous operation record are displayed, the ink mark canceling is realized, the data loss can be avoided while the operation is simplified, the user can edit the ink marks conveniently, and the user experience is improved.
The ink canceling method provided by the embodiment of the present invention is described in detail below with reference to specific embodiments.
As shown in fig. 2, a schematic flow chart of an ink canceling method provided in an embodiment of the present invention includes the following steps:
step S201: after opening a demonstration manuscript display page, establishing a blank operation record; and pointing the preset ink pointer to the blank operation record.
In this step, after the interface for displaying the presentation is opened, the ink editing operation is not performed, but an operation record is required to reflect the initial state at this time, otherwise, the ink editing operation cannot be cancelled to the initial state when the cancellation is performed. Therefore, a blank operation record is established, no ink editing operation is recorded in the blank operation record, and the ink pointer points to the blank operation record to indicate that the ink state in the displayed page corresponds to the blank operation record, namely that no ink exists in the displayed page.
Step S202: the user's operation is monitored.
In one implementation, the user's operations are monitored, primarily the user's operations related to ink.
Step S203: when the ink editing operation is monitored, adding an operation record corresponding to the current ink editing operation after the operation record pointed by the current ink pointer.
In this step, when it is monitored that the user performs the ink editing operation, an operation record corresponding to the ink editing operation of the user is established. In one implementation, if no other operation record exists after the operation record pointed by the current ink pointer, the operation record corresponding to the current ink editing operation is added to the last end of the operation record list. In another implementation manner, if there are other operation records originally after the operation record pointed by the current ink pointer, the operation record corresponding to the current ink editing operation is added between the operation record pointed by the current ink pointer and the next operation record.
In one implementation, a user's editing operation on ink includes: an ink drawing operation and an ink erasing operation, among others. The ink erasing operation includes an operation of erasing selected ink and an operation of erasing all ink at once. Of course, other operations that change the state of the ink may be included in the prior art, such as: the embodiment of the present invention does not limit the movement, rotation, and scaling of the ink.
Step S204: and pointing the preset ink pointer to the currently added operation record.
In this step, since the corresponding operation record is added after monitoring the ink editing operation of the user, the pointing direction of the ink pointer is changed correspondingly, and the ink pointer points to the currently added operation record, thereby ensuring that the ink editing operation recorded in the operation record pointed by the ink pointer is: the user edits the latest ink on the presentation page of the presentation.
Step S205: when the operation cancellation is monitored, judging whether the operation record pointed by the ink pointer currently is a blank operation record; if not, the ink pointer is pointed to the last operation record of the currently pointed operation record.
In this step, if the operation record currently pointed by the ink pointer is a blank operation record, it indicates that the ink state in the presentation page of the current presentation is an initial state when the presentation page is opened, and since the blank operation record is the first operation record, when the operation record currently pointed by the ink pointer is a blank operation record, there is no "previous operation record", that is, at this time, a cancel operation cannot be performed, and the direction of the ink pointer does not need to be changed.
Therefore, it is necessary to determine whether the operation record currently pointed to by the ink pointer is a blank operation record, and when the operation record currently pointed to by the ink pointer is not a blank operation record, point the ink pointer to the operation record that is previous to the operation record currently pointed to.
Step S206: and refreshing the display page, and displaying the operation record pointed by the ink pointer and the ink corresponding to the ink editing operation recorded in the previous operation record.
In one implementation mode, after the display page is refreshed, according to the operation record pointed by the modified ink pointer and the previous operation record, corresponding ink editing operation is performed on the display page of the presentation document again, and the cancelled ink editing operation is not executed any more, so that the ink corresponding to the cancelled ink editing operation is not displayed any more. And the ink editing operation corresponding to the operation record after the operation record pointed by the modified ink pointer is not re-executed and displayed, but still stored and not deleted, and can be recovered according to the needs of the user, thereby avoiding data loss.
For example, in one case, if the cancelled ink editing operation is a drawing operation on an ink, after the cancellation operation, the ink is edited again, the ink is not drawn any more, and the ink is not displayed on the display page; in another case, if the undone ink editing operation is an erase operation on an ink, the ink is re-displayed on the presentation page after the undoing operation, through re-editing, without erasing the ink.
As can be seen from the above, the ink revocation method provided in the embodiment of the present invention changes the pointing direction of the ink pointer according to the revocation operation of the user by recording each time of the ink editing operation, and displays the operation record pointed by the ink pointer and the ink corresponding to the previous operation record, thereby realizing the revocation of the ink, simplifying the operation, avoiding the data loss, facilitating the user to edit the ink, and improving the user experience.
As shown in fig. 3, a flow chart of another ink canceling method provided in the embodiment of the present invention includes the following steps:
step S301: after opening a demonstration manuscript display page, establishing a blank operation record; and pointing the preset ink pointer to the blank operation record.
Step S302: the user's operation is monitored.
Step S303: when the ink editing operation is monitored, adding an operation record corresponding to the current ink editing operation after the operation record pointed by the current ink pointer.
Step S304: and pointing the preset ink pointer to the currently added operation record.
Step S305: when the operation cancellation is monitored, judging whether the operation record pointed by the ink pointer currently is a blank operation record; if not, the ink pointer is pointed to the last operation record of the currently pointed operation record.
In one implementation, the above-mentioned undo operation is implemented by the shortcut key CTRL + Z.
In parallel, step S306: when the recovery operation is monitored, judging whether the operation record currently pointed by the ink pointer is the last operation record; if not, pointing the ink pointer to the next operation record of the currently pointed operation record; if so, the pointing direction of the ink pointer is not changed.
Therefore, in this step, if the operation record to which the ink pointer currently points is the last operation record, it indicates that the ink state in the presentation page of the current presentation is the latest state after the user edits the ink on the presentation page, and the revocation operation has not been performed before, and there is no ink editing operation that can be resumed, that is, the resumption operation cannot be performed, and the pointing direction of the ink pointer does not need to be changed.
Therefore, it is necessary to determine whether the operation record currently pointed to by the ink pointer is the last operation record, and when the operation record currently pointed to by the ink pointer is not the last operation record, point the ink pointer to the operation record next to the operation record currently pointed to.
In one implementation, the above-described recovery operation is implemented by the shortcut key CTRL + Y.
Step S307: and refreshing the display page, and displaying the operation record pointed by the ink pointer and the ink corresponding to the ink editing operation recorded in the previous operation record.
For example, in one case, for a drawing operation of an ink, if a recovery operation is performed after an undo operation, the ink is re-edited and re-drawn, and the ink is re-displayed on the display page; in another case, for an erasing operation of an ink, if a recovery operation is performed after the undo operation, the ink is re-edited and erased again, and the ink is not displayed on the display page.
Steps S301 to S305 are the same as steps S201 to S205 of the embodiment of the invention shown in fig. 2, and step S307 is the same as step S206 of the embodiment of the invention shown in fig. 2, and are not repeated here.
As can be seen from the above, the ink revocation method provided in the embodiment of the present invention changes the pointing direction of the ink pointer by recording each ink editing operation and according to the revocation operation and the recovery operation of the user, and displays the operation record pointed by the ink pointer and the ink corresponding to the previous operation record, thereby realizing the revocation of the ink, and also recovering the revoked ink, so as to avoid data loss while simplifying the operation, facilitate the user to edit the ink, and improve the user experience.
For ease of understanding, the ink canceling method shown in fig. 3 is explained below by way of a specific example.

The list of operation records and the pointing direction of the ink pointer at this time are as shown in fig. 5, only one blank operation record is in the operation record list, which reflects the initial state of the display page, and the ink pointer pos points to the blank operation record.
As shown in fig. 6, the effect diagram is obtained after the user performs the ink drawing operation three times on the presentation page of the presentation shown in fig. 4, where three inks "1", "2", and "3" exist on the presentation page. The list of operation records and the pointing of the ink pointer at this time are shown in fig. 7, and in addition to the blank operation record, there are operation records corresponding to three inks in the operation record list, and the ink pointer pos points to the currently added operation record, that is, the fourth operation record.
As shown in fig. 8, the effect diagram is obtained after the user performs a cancel operation on the presentation page of the presentation shown in fig. 6, where two ink marks "1" and "2" exist on the presentation page. The list of operation records and the pointing direction of the ink pointer at this time are shown in fig. 9, and the four operation records in the operation record list are identical to those in fig. 7, but the ink pointer pos points to the last operation record, i.e., the third operation record.
As shown in fig. 10, the effect diagram after the user performs the restore operation once on the presentation page of the presentation shown in fig. 8 is exactly the same as that in fig. 6. The list of operation records and the pointing direction of the ink pointer at this time are exactly the same as those in fig. 7, as shown in fig. 11.
As shown in fig. 12, the effect diagram after the user performs the three-time undo operation on the presentation page of the presentation shown in fig. 10 is exactly the same as that in fig. 4. The list of operation records and the pointing direction of the ink pointer at this time are as shown in fig. 13, and the four operation records in the operation record list are identical to those in fig. 11, but the ink pointer pos points to three previous operation records, that is, the blank operation record.
As shown in fig. 14, the effect diagram is shown after the user performs an ink editing operation on the presentation page of the presentation shown in fig. 8. The list of operation records and the pointing direction of the ink pointer at this time are as shown in fig. 15, the operation record corresponding to the current ink editing operation is added between the operation record to which the ink pointer points and the next operation record shown in fig. 9, and the ink pointer pos points to the currently added operation record.
