Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to reduce operation complexity when a user modifies the showing time length, the embodiment of the invention provides a method and a device for modifying the showing time length of a presentation and electronic equipment.
Referring to fig. 1, fig. 1 is a flowchart of a method for modifying a presentation showing duration, which specifically includes the following steps:
step 101, receiving a showing duration modification instruction of a user.
The user can give the modification instruction in different modes according to own habits, so that the method for receiving the projection duration modification instruction of the user can be various, and the method is not limited. For example, it may be:
receiving a showing duration modification instruction given by a user in a mode of clicking a first preset button in a presentation editing page; or receiving a showing duration modification instruction given by a mode of clicking a preset shortcut key of a keyboard by a user; or receiving a showing duration modification instruction given by the user by clicking a second preset button in the right button menu of the mouse.
Step 102, displaying a showing time length modification interface, wherein the showing time length modification interface comprises showing time length information of each slide in the presentation.
The showing time length modification interface can comprise the showing time length of each slide in the presentation, the showing time length can be the showing time length in the last training showing process, the showing time length set by the user through the showing time length modification interface according to the self requirement, and the showing time length of the slides which are not set with the showing time length can be set to 0.
Further, to help the user quickly understand the content of each slide, so as to determine whether to modify the slide, and determine the modified showing duration, the showing duration modification interface may further include: thumbnail images of the slides, title information of the slides, and the like, for example: thumbnail images of each slide and main title content of each slide.
Step 103, when receiving new showing time length information of the target slide inputted by the user in the showing time length modification interface, modifying the showing time length of the target slide to be the new showing time length.
Specifically, the "confirm" and "cancel" buttons may be set in the show duration modification interface, when it is detected that the user inputs new show duration information of the target slide in the show duration modification interface and clicks the "confirm" button, the show duration modification interface disappears, and the new show duration information of the target slide input by the user is confirmed to be received, otherwise, the new show duration information input by the user is confirmed not to be received, and a specific manner for confirming the receipt of the new show duration information input by the user is not limited herein.
As can be seen from the above embodiments, when the user needs to modify the showing duration of the specified slide in the presentation, the embodiment of the present invention can directly input new showing duration information in the showing duration modification interface, without performing the sparing showing operation again, thereby reducing the complexity of the user operation.
In the embodiment of the invention, the showing time length modification interface can further comprise: when receiving the new total showing time length of the presentation file input by the user in the showing time length modification interface, the new showing time length of each slide in the presentation file can be calculated according to a preset showing time length calculation method, and the showing time length of each slide is modified to be the new showing time length of each slide.
Referring to fig. 2, fig. 2 is another flow chart of a method for modifying a presentation showing duration according to an embodiment of the present invention, and specific steps may include:
step 201, receiving a showing duration modification instruction of a user.
The content of step 201 is the same as that of step 101, and will not be described here again.
Step 202, displaying a showing time length modification interface, wherein the showing time length modification interface comprises showing time length information of each slide in the presentation.
Referring to fig. 3, fig. 3 is a schematic diagram of a showing duration modification interface in this embodiment, where the showing duration modification interface includes, in addition to showing duration information of each slide, a total showing duration of a presentation, page number information of each slide, a thumbnail of each slide, and title information of each slide, where the total showing duration is a sum of showing durations of each slide in the presentation, and a duration unit is seconds(s).
Step 203, when receiving the new showing time length information of the target slide inputted by the user in the showing time length modification interface, modifying the showing time length of the target slide to the new showing time length.
The content of step 203 is the same as that of step 103, and will not be described here again.
Step 204, modifying the total presentation duration of the presentation according to the difference between the presentation duration of the target slide and the new presentation duration.
Taking fig. 3 as an example, when the user increases the showing time length of the 1 st slide from 3s to 5s and the 4 th slide from 0s to 1s, namely: the difference between the showing time length of the target slides 1 and 4 and the new showing time length is 3s, and accordingly, the showing total time length of the presentation is increased by 3s from 12s to 15s.
Step 205, when receiving a new total showing duration of the presentation, which is input by the user in the showing duration modification interface, the total number of pages of the slides in the presentation is obtained according to the page number information of each slide.
Step 206, calculating the difference between the new total duration of the presentation and the total duration of the presentation as a first difference.
Step 207, according to the uniform distribution principle and the order principle that the page numbers are from small to large, the first difference values are distributed to the slides in a scattered manner, and the new showing time length of each slide in the presentation is obtained.
Specifically, a ratio of the first difference value to the total duration of the presentation may be calculated, and then the duration of the presentation of each slide may be adjusted according to the ratio, so as to obtain a new duration of the presentation of each slide in the presentation, or may be: the method comprises the steps of firstly, uniformly distributing part of time lengths in a first difference value to each slide, and then distributing the rest part of time lengths which cannot be uniformly distributed to the part of slides according to the sequence of page numbers from small to large, so that new showing time lengths of the slides are obtained, and the specific method for obtaining the new showing time lengths of the slides in the presentation is not limited.
Step 208, modifying the length of the slide show to a new length of the slide show.
In the embodiment of the invention, when the user needs to modify the showing time length of the specified slide in the presentation, new showing time length information can be directly input in the showing time length modification interface without performing the sparing showing operation again, so that the complexity of the user operation is reduced. Meanwhile, when the user modifies the total duration of the presentation, the difference between the new total duration of the presentation and the original total duration of the presentation can be uniformly distributed to each slide according to the uniform distribution principle and the order principle of the page numbers from small to large, so that the variation range of the duration of the presentation of each slide is more uniform before and after the duration of the presentation is modified, and the use experience of the user is further improved.
Referring to fig. 4, in the embodiment shown in fig. 2, the new showing duration of each slide in the presentation may be obtained by:
in step 401, it is determined whether the first difference is greater than 0. When the first difference is greater than 0, step 402 is performed; when the first difference is not greater than 0, step 405 is performed;
step 402, dividing the first difference value by the total number of pages to obtain a first quotient and a first remainder. If the first remainder is 0, go to step 403; if the first remainder is not 0, step 404 is performed.
Step 403, determining the sum of the showing time length and the first quotient value of each slide as the new showing time length of each slide.
Step 404, a first quotient is respectively allocated to each slide, and the first remainder is uniformly allocated to part of the slides according to the order of the page numbers from small to large, so that new showing time lengths of the slides are respectively obtained.
For example, taking fig. 3 as an example, when the total duration increases by 14s, the first difference is 14s, the total number of pages of the slides is 4, the first quotient is 3, and the first remainder is 2s, at this time, 3 may be first allocated to each slide, that is, each slide showing duration increases by 3s, and then the first remainder 3 may be uniformly allocated to part of slides in order of page numbers from small to large: uniformly distributing 3s to the slides on the 1 st page, the 2 nd page and the 3 rd page, and finally obtaining the new showing duration of each slide as follows: page 1: 7s; page 2: 8s; page 3: 8s; page 4: 3s.
Step 405, dividing the absolute value of the first difference value by the total number of pages to obtain a second quotient and a second remainder. If the second remainder is 0, execute step 406; if the second remainder is not 0, step 409 is performed.
Step 406, calculating a plurality of second differences between the showing duration of each slide and the second quotient, wherein each slide corresponds to one second difference. If the second difference value corresponding to each slide is greater than or equal to 0, step 407 is executed; if there is a first slide with a second difference less than 0, step 408 is performed.
Step 407, determining the new showing duration of each slide as the second difference value corresponding to each slide.
Step 408, determining a new showing duration of the first slide to be 0; and respectively distributing the second quotient to the second slides with the second difference value larger than 0, uniformly distributing the second difference value of the first slides to part of the second slides according to the sequence of page numbers from small to large, and respectively obtaining new showing time lengths of the slides.
Also taking fig. 3 as an example, when the total duration decreases by 8s, the first difference is-8, the second quotient is 2s, and the second differences corresponding to the slides are sequentially: 1s, 2s, 3s and-2 s, wherein the first slides are the 4 th slide, the new showing time length of the 4 th slide is determined to be 0, the second quotient 2 is respectively allocated to the second slide with the second difference value larger than 0, namely the 1 st slide, the 2 nd slide and the 3 rd slide, the second difference value-2 of the first slide is uniformly allocated to part of the second slide, namely the 1 st slide and the 2 nd slide according to the sequence of page numbers from small to large, and the new showing time length of each slide is sequentially: 0s, 1s, 3s and 0s.
Step 409, calculating a plurality of third differences between the showing time length of each slide and the second quotient; each slide corresponds to a third difference value. If the third difference value corresponding to each slide is greater than or equal to 0, step 410 is executed; if there is a third slide with a third difference less than 0, step 411 is performed.
In step 410, the second quotient is respectively assigned to each slide, and the second remainder is uniformly assigned to part of the slides in the order of from the small page number to the large page number, so as to respectively obtain the new showing duration of each slide.
For example: the total 4 pages of slides of the demonstration document are displayed, and the showing duration of each page is as follows in sequence: 3s, 4s, 5s, 3s, when the total duration is reduced by 10s, the first difference value is-10 s, the second quotient value is 2, the second remainder is 2s, the second quotient value 2 is respectively allocated to each slide, the second remainder 2s is uniformly allocated to part of second slides, namely the 1 st slide and the 2 nd slide according to the sequence of page numbers from small to large, and the new showing duration of each slide is obtained by sequentially: 0s, 1s, 3s and 1s.
Step 411, determining a new showing duration of the third slide to be 0; and respectively distributing the second quotient to a fourth slide with a third difference value greater than 0, uniformly distributing the second remainder and the third difference value of the third slide to a part of the fourth slides according to the sequence of page numbers from small to large, and respectively obtaining new showing duration of each slide.
