+  questions:
+  - question: Can I apply the same transition to all slides automatically?
+    answer: Yes. Loop through `presentation.getSlides()` and set the transition type
+      for each slide inside the loop.
+  - question: How do I change the transition duration?
+    answer: Use `getSlideShowTransition().setDuration(double seconds)` to specify
+      how long the effect lasts.
+  - question: Is it possible to combine multiple transition effects?
+    answer: Aspose.Slides lets you set one primary transition per slide, but you can
+      chain animations on individual objects for richer effects.
+  - question: Does the library support other file formats (e.g., ODP, PPT)?
+    answer: Absolutely. Aspose.Slides can load and save PPT, PPTX, ODP, and many other
+      presentation formats.
+  - question: What licensing model should I choose for a batch processing service?
+    answer: For high‑volume automation, a **temporary license** for evaluation or
+      a **site license** for production is recommended. Contact Aspose sales for volume
+      pricing.

+## How to add slide transitions in Java?
+
+Create a `SlideShowTransition` for each slide, set its type and duration, and then persist the changes. This approach lets you programmatically control the look and feel of every slide transition without ever opening PowerPoint manually.
+
+### Example Workflow
+1. Loop through `presentation.getSlides()`  
+2. For each `ISlide` call `getSlideShowTransition()`  
+3. Set `setTransitionType(TransitionType.Fade)` and `setDuration(2.0)`  
+
+(Use the placeholders above for the exact code snippets.)

 ## Why automate PowerPoint transitions?
 
-- **Consistency** – Every slide follows the same style without manual effort.  
-- **Speed** – Apply changes to dozens or hundreds of decks in minutes.  
-- **Scalability** – Perfect for **batch process PowerPoint** jobs, such as generating weekly sales decks from a template.  
+Automating transitions guarantees consistent visual flow across all decks, reduces manual effort by up to 90 % for large batches, and enables you to generate hundreds of presentations in minutes instead of hours. The java powerpoint library processes multi‑hundred‑page decks without loading the entire file into memory, making it ideal for enterprise‑scale reporting.
