+## **FAQ**
+
+**What happens to slide indexes after I delete a slide?**
+
+After deletion, the [collection](https://reference.aspose.com/slides/java/com.aspose.slides/slidecollection/) reindexes: every subsequent slide shifts left by one position, so previous index numbers become outdated. If you need a stable reference, use each slide’s persistent ID rather than its index.
+
+**Is a slide’s ID different from its index, and does it change when neighboring slides are deleted?**
+
+Yes. The index is the slide’s position and will change when slides are added or removed. The slide ID is a persistent identifier and does not change when other slides are deleted.
+
+**How does deleting a slide affect slide sections?**
+
+If the slide belonged to a section, that section will simply contain one fewer slide. The section structure remains; if a section becomes empty, you can [remove or reorganize sections](/slides/java/slide-section/) as needed.
+
+**What happens to notes and comments attached to a slide when it’s deleted?**
+
+[Notes](/slides/java/presentation-notes/) and [comments](/slides/java/presentation-comments/) are tied to that specific slide and are removed along with it. Content on other slides is unaffected.
+
+**How is deleting slides different from cleaning up unused layouts/masters?**
+
+Deleting removes specific normal slides from the deck. Cleaning up unused layouts/masters removes layout or master slides that nothing references, reducing file size without changing remaining slide content. These actions are complementary: typically delete first, then clean up.

+## **FAQ**
+
+**What is a Slide Master in PowerPoint?**
+
+A Slide Master is a slide template that defines the layout, styles, themes, fonts, background, and other properties for slides in a presentation. It allows you to set and change the look of all presentation slides at once.  
+
+**How is a Slide Master applied in a presentation?**
+
+Every presentation has at least one Slide Master by default. When a new slide is added, a Slide Master is applied to it automatically, typically inheriting the master of the previous slide. A presentation can contain multiple Slide Masters to style different parts uniquely.  
+
+**What elements can be customized in a Slide Master?**
+
+A Slide Master comprises several core properties that can be customized:
+
+- **Background**: Set the slide background.
+- **BodyStyle**: Define text styles for the slide's body.
+- **Shapes**: Manage all shapes on the Slide Master, including placeholders and picture frames.
+- **Controls**: Handle ActiveX controls.
+- **ThemeManager**: Access the theme manager.
+- **HeaderFooterManager**: Manage headers and footers.  
+
+**How can I add an image to a Slide Master?**
+
+Adding an image to a Slide Master ensures it appears on all slides that depend on that master. For example, placing a company logo on the Slide Master will display it on every slide in the presentation.  
+
+**How do Slide Masters relate to Slide Layouts?**
+
+Slide Layouts work in conjunction with Slide Masters to provide flexibility in slide design. While a Slide Master defines overarching styles and themes, Slide Layouts allow for variations in content arrangement. The hierarchy is as follows:
+
+- **Slide Master** → Defines global styles.
+- **Slide Layout** → Provides different content arrangements.
+- **Slide** → Inherits design from its Slide Layout.
+
+**Can I have multiple Slide Masters in a single presentation?**
+
+Yes, a presentation can contain several Slide Masters. This allows you to style different sections of a presentation in various ways, providing flexibility in design.  
+
+**How do I access and modify a Slide Master using Aspose.Slides?**
+
+In Aspose.Slides, a Slide Master is represented by the [IMasterSlide](https://reference.aspose.com/slides/java/com.aspose.slides/imasterslide/) interface. You can access a Slide Master using the [getMasters](https://reference.aspose.com/slides/java/com.aspose.slides/presentation/#getMasters--) method of the [Presentation](https://reference.aspose.com/slides/java/com.aspose.slides/presentation/) object.

+**Are sections preserved when saving to the PPT (PowerPoint 97–2003) format?**
 
+No. The PPT format does not support section metadata, so section grouping is lost when saving to .ppt.
+
+**Can an entire section be "hidden"?**
+
+No. Only individual slides can be hidden. A section as an entity has no "hidden" state.
+
+**Can I quickly find a section by a slide and, conversely, the first slide of a section?**
+
+Yes. A section is uniquely defined by its starting slide; given a slide you can determine which section it belongs to, and for a section you can access its first slide.

+## **FAQ**
+
+**Can I set a custom slide size using units other than inches (for example, points or millimeters)?**
+
+Yes. Aspose.Slides uses points internally, where 1 point equals 1/72 of an inch. You can convert any unit (such as millimeters or centimeters) to points and use the converted values to define slide width and height.
+
+**Will a very large custom slide size affect performance and memory usage during rendering?**
+
+Yes. Larger slide dimensions (in points) combined with higher rendering scale lead to increased memory consumption and longer processing times. Aim for a practical slide size and adjust rendering scale only as needed to achieve the desired output quality.
+
+**Can I define one non-standard slide size and then merge slides from presentations that have different sizes?**
+
+You can’t [merge presentations](/slides/java/merge-presentation/) while they have different slide sizes — first, resize one presentation to match the other. When changing the slide size, you can choose how existing content is handled via the [SlideSizeScaleType](https://reference.aspose.com/slides/java/com.aspose.slides/slidesizescaletype/) option. After aligning sizes, you can merge slides while preserving formatting.
+
+**Can I generate thumbnails for individual shapes or specific regions of a slide, and will they respect the new slide size?**
+
+Yes. Aspose.Slides can render thumbnails for [entire slides](https://reference.aspose.com/slides/java/com.aspose.slides/slide/#getImage-com.aspose.slides.IRenderingOptions-float-float-) as well as for [selected shapes](https://reference.aspose.com/slides/java/com.aspose.slides/shape/#getImage-int-float-float-). The resulting images reflect the current slide size and aspect ratio, ensuring consistent framing and geometry.

+## **FAQ**
+
+**Can I control the playback speed of a slide transition?**
+
+Yes. Set the transition’s [speed](https://reference.aspose.com/slides/java/com.aspose.slides/slideshowtransition/#setSpeed-int-) using the [TransitionSpeed](https://reference.aspose.com/slides/java/com.aspose.slides/transitionspeed/) setting (e.g., slow/medium/fast).
+
+**Can I attach audio to a transition and make it loop?**
+
+Yes. You can embed a sound for the transition and control behavior via settings like sound mode and looping (e.g., [setSound](https://reference.aspose.com/slides/java/com.aspose.slides/slideshowtransition/#setSound-com.aspose.slides.IAudio-), [setSoundMode](https://reference.aspose.com/slides/java/com.aspose.slides/slideshowtransition/#setSoundMode-int-), [setSoundLoop](https://reference.aspose.com/slides/java/com.aspose.slides/slideshowtransition/#setSoundLoop-boolean-), plus metadata such as [setSoundIsBuiltIn](https://reference.aspose.com/slides/java/com.aspose.slides/slideshowtransition/#setSoundIsBuiltIn-boolean-) and [setSoundName](https://reference.aspose.com/slides/java/com.aspose.slides/slideshowtransition/#setSoundName-java.lang.String-)).
+
+**What’s the fastest way to apply the same transition to every slide?**
+
+Configure the desired transition type on each slide’s transition settings; transitions are stored per slide, so applying the same type across all slides gives a consistent result.
+
+**How can I check which transition is currently set on a slide?**
+
+Inspect the slide’s [transition settings](https://reference.aspose.com/slides/java/com.aspose.slides/baseslide/#getSlideShowTransition--) and read its [transition type](https://reference.aspose.com/slides/java/com.aspose.slides/slideshowtransition/#setType-int-); that value tells you exactly which effect is applied.
