| Figure | Caption |
|---|---|
| 189 / 82 | Shape types and chart types, each a real object that PowerPoint still recognises and lets a person edit. |
| 13 -> 12 | Presentation formats read and written, including the pre-2007 binary .ppt container and OpenDocument .odp, plus 9 further export targets. |
| 1 | JAR, resolved from the Aspose repository rather than Maven Central. Its POM declares no dependencies, so nothing is dragged in behind it and nothing native sits beside it. |
| Java 6+ | The one real prerequisite. This is pure Java, so no Office install, no COM automation and no X display enter the picture, but it runs inside a JVM and it wants fontconfig and installed fonts wherever it renders. |

## Five things people actually write

| Task | Hint | Flow | Note | Docs |
|---|---|---|---|---|
| Convert | Read a deck once and write it back out in whichever formats your readers actually open. | PPTX -> PDF / HTML / TIFF | One Presentation instance, saved three times. Call dispose() in a finally block to release the file handles and the render cache. | https://docs.aspose.com/slides/java/convert-powerpoint-to-pdf/ |
| Slide thumbnails | Render any slide to a bitmap at a size you pick, with no PowerPoint and no screenshot. | ISlide -> IImage -> PNG | getImage() also accepts a scale pair or a RenderingOptions for notes and comments. Dispose each IImage as you go so a long deck never holds every bitmap at once. | https://docs.aspose.com/slides/java/convert-slide/ |
| Charts from data | Turn your own arrays into a native PowerPoint chart that stays editable after you hand it over. | double[] -> IChart -> PPTX | The chart carries a real embedded workbook, so whoever opens the deck can pull up the data sheet and change a number. | https://docs.aspose.com/slides/java/create-chart/ |
| Protect | Encrypt a deck so it cannot be opened, and mark it so it cannot be saved over. | PPTX -> encrypted PPTX | encrypt() sets the open password and genuinely encrypts the file. setWriteProtection() only sets the modify password, and does not. | https://docs.aspose.com/slides/java/password-protected-presentation/ |
| Merge | Fold several decks into one, carrying each slide's layout and master across with it. | 3 x PPTX -> 1 PPTX | addClone() brings the source layout and master along when the destination has no match. Overloads let you force a destination layout or master instead. | https://docs.aspose.com/slides/java/merge-presentation/ |

## What goes in, what comes out

## Capabilities, one line each

## Runs where your code already runs

| Runtime | Note | Platforms |
|---|---|---|
| .NET | The C# and VB.NET build of the same object model, on .NET and .NET Framework. | WINDOWS · LINUX · MACOS |
| C++ | A native build for C++ projects, with no managed runtime sitting underneath it. | WINDOWS · LINUX · MACOS |
| Python via .NET | The Python package, with the .NET runtime it needs shipped inside the wheel. | WINDOWS · LINUX · MACOS |
| PHP via Java | This same JAR, driven from PHP over a Java bridge. A JVM is required there too. | WINDOWS · LINUX · MACOS |
| Android via Java | The same object model built against the Android runtime, for on-device work. | ANDROID |

## Start with the trial, license when you ship

The trial is the full API. It applies an evaluation watermark when a presentation is opened or saved and replaces extracted text with an evaluation notice, so you can test the formats you actually care about before you talk to anyone. A temporary licence lifts both for 30 days.

## In use

The product worked as advertised, the documentation was easy to follow, and the support forums were all the help we needed. The final solution that we deployed has exceeded our initial expectations by a great deal.
