|
||
| `rct-screenshotter` is a simple web server that generates screenshots of Rollercoaster Tycoon save files. | ||
|
|
||
| This project is intended to be used as a REST API for projects like [ffa-tycoon](https://github.com/CorySanin/ffa-tycoon). But it also has a form on its homepage to allow for use in a web browser. | ||
|
|
||
| It uses OpenRCT2 to generate screenshots, and as such is compatible with RCT1, RCT2, and OpenRCT2 save formats. | ||
|
|
||
| ## API | ||
|
|
||
| Submit a multipart post request to /upload with the following fields: | ||
|
|
||
| | Name | Description | | ||
| |----------|---------------------------------------------------------| | ||
| | park | The save file to generate a screenshot of | | ||
| | zoom | The zoom level to use in the screenshot. 0-7 (optional) | | ||
| | rotation | The rotation of the map. 0-3 (optional) | |
