| Label | Install |
|---|---|
| pip | pip install aspose-slides-java |
| Prerequisite | JRE 8 or newer, JAVA_HOME set |
| Module | asposeslides |

| 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. |
| 2 | Python packages pip installs: the Aspose.Slides wheel and the JPype1 bridge it pulls in with it. |
| 1 | Java runtime you provide yourself. JRE 8 or newer, headless is fine, and no Microsoft Office anywhere. |

## Five things people actually write

| Task | Hint | Flow | Note | Docs |
|---|---|---|---|---|
| Convert | One load, many output formats | PPTX -> PDF / HTML / TIFF | The rendering engine is inside the package. Nothing else to install. | https://docs.aspose.com/slides/java/converting-a-presentation/ |
| Slide thumbnails | Images for a viewer or an index | PPTX -> PNG | getImage returns an IImage. The scale factors set the output resolution. | https://docs.aspose.com/slides/python-java/modern-api/ |
| Charts from data | A real chart, still editable in PowerPoint | DATA -> PPTX | Chart data lives in an embedded workbook. 82 chart types. | https://docs.aspose.com/slides/java/create-chart/ |
| Protect | Encrypt the deck and the PDF you hand out | PPTX -> ENCRYPTED PPTX / PDF | The password applies to the deck and to the export. | https://docs.aspose.com/slides/java/password-protected-presentation/ |
| Merge | Clone slides between decks, layouts intact | PPTX + PPTX -> PPTX | Layouts and masters travel with the cloned slide. | https://docs.aspose.com/slides/java/merge-presentation/ |

## What goes in, what comes out

- **Read and written** (presentation files, proven by writing each one and reading it back) — FODP, ODP, OTP, POT, POTM, POTX, PPS, PPSM, PPSX, PPT, PPTM, PPTX
- **Read only** (no writer in the API) — PPT95
- **Written only** (export targets, not presentation files) — GIF, HTML, HTML5, MD, PDF, SWF, TIFF, XML, XPS
- **Slide images** (rendered from a slide) — BMP, EMF, GIF, JPEG, PNG, SVG, TIFF
- **Other content read in** (placed into a presentation rather than opened as one) — HTML, PDF, raster image

Read from the shipping package on 2026-08-21 by writing each file out and reading it back in.

## Capabilities, one line each

## Runs where your code already runs

| Runtime | Note | Platforms |
|---|---|---|
| CPython 3.7 to 3.14 | The interpreter range the wheel declares on PyPI. | WINDOWS · LINUX · MACOS |
| JRE 8 or newer | The engine is Java, so a Java runtime hosts it. Any JRE from 8 up, current LTS releases included. | WINDOWS · LINUX · MACOS |
| JPype1 bridge | Installed with the package. It starts the JVM inside your Python process, so there is no server and no socket. | IN-PROCESS |
| Containers | A base image with Python and a headless JRE is the whole dependency list. | DOCKER · LINUX |
| Server frameworks and workers | Django, Flask, FastAPI and queue workers, with one JVM per process. | LINUX · WINDOWS · MACOS |

## 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.
