O čem je tato stránka

Naučte se, jak spravovat prezentace v Aspose.Slides pro Python přes Java. Ovládejte přechody snímků, časování a další funkce v formátech PPT, PPTX a ODP s lehkostí.

Úvod

Microsoft PowerPoint’s Set Up Show options let you choose the show type, enable looping, select slides, and control how slides advance. With Aspose.Slides for Python via Java, you can configure these options programmatically and save them in a presentation file.

The Presentation.getSlideShowSettings method returns a SlideShowSettings object that controls these options. The examples below require Aspose.Slides for Python via Java and a compatible Java runtime. Each example starts the JVM if needed and releases the presentation when finished.

Vyberte typ prezentace

SlideShowSettings.setSlideShowType defines the type of slide show, which can be an instance of the following classes: PresentedBySpeaker, BrowsedByIndividual, or BrowsedAtKiosk. Using this method allows you to adapt the presentation for different usage scenarios, such as automated kiosks or manual presentations.

The code example below creates a new presentation and sets the show type to “Browsed by an individual” without displaying the scrollbar.

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import Presentation, SaveFormat, BrowsedByIndividual

presentation = Presentation()
try:
    show_type = BrowsedByIndividual()
    show_type.setShowScrollbar(False)
    presentation.getSlideShowSettings().setSlideShowType(show_type)

    presentation.save("output.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

SlideShowSettings.setLoop determines whether the slide show should repeat in a loop until manually stopped. This is useful for automated presentations that need to run continuously. SlideShowSettings.setShowNarration determines whether voice narrations should be played during the slide show. It is useful for automated presentations that contain voice guidance for the audience. SlideShowSettings.setShowAnimation determines whether animations added to slide objects should be played. This is useful for providing the full visual effect of the presentation.

The following code example creates a new presentation and loops the slide show.

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import Presentation, SaveFormat

presentation = Presentation()
try:
    presentation.getSlideShowSettings().setLoop(True)

    presentation.save("output.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

Vyberte snímky k zobrazení

The SlideShowSettings.setSlides method allows you to select a range of slides to be shown during the presentation. This is useful when you need to show only part of the presentation rather than all slides. The following code example creates a presentation with nine slides and selects slides 2 through 9. The range uses one-based slide numbers.

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import Presentation, SaveFormat, SlidesRange

presentation = Presentation()
try:
    # Vytvořte devět snímků, aby vybraný rozsah existoval.
    first_slide = presentation.getSlides().get_Item(0)
    for _ in range(8):
        presentation.getSlides().addClone(first_slide)

    slide_range = SlidesRange()
    slide_range.setStart(2)
    slide_range.setEnd(9)
    presentation.getSlideShowSettings().setSlides(slide_range)

    presentation.save("output.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

Ovládání postupu snímků

The SlideShowSettings.setUseTimings method allows you to enable or disable the use of preset timings for each slide. This is useful for automatically showing slides with pre-defined display durations. The code example below creates a new presentation and disables the use of timings.

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import Presentation, SaveFormat

presentation = Presentation()
try:
    presentation.getSlideShowSettings().setUseTimings(False)

    presentation.save("output.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

Zobrazit ovládací prvky médií

The SlideShowSettings.setShowMediaControls method determines whether media controls (such as play, pause, and stop) should be displayed during the slide show when multimedia content (e.g., video or audio) is played. This is useful when you want to give the presenter control over media playback during the presentation.

The following code example creates a new presentation and enables media controls to be displayed.

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import Presentation, SaveFormat

presentation = Presentation()
try:
    presentation.getSlideShowSettings().setShowMediaControls(True)

    presentation.save("output.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

Často kladené otázky

Mohu uložit prezentaci tak, aby se po otevření rovnou spustila v režimu prezentace?

Ano. Save the file as PPSX or PPSM; these formats launch directly in slide show mode when opened in PowerPoint. In Aspose.Slides, choose the corresponding save format během exportu.

Mohu vyloučit jednotlivé snímky z prezentace, aniž bych je smazal ze souboru?

Ano. Mark a slide as hidden. Hidden slides remain in the presentation but are not displayed during the slide show.

Může Aspose.Slides přehrávat prezentaci nebo ovládat živou prezentaci na obrazovce?

Ne. Aspose.Slides edits, analyzes, and converts presentation files; the actual playback is handled by a viewer application such as PowerPoint.
