Rotate Pages
Introduction
This REST API allows changing page rotation angle by setting it to 90,180 or 270 degrees for specific or all document pages. The result is a new document that has rotation changed for specified pages. There are several ways to specify desired page numbers:
- Provide exact page numbers via Pages collection;
- Specify pages range start/end page numbers. There is also an ability to get only even/odd pages from the specified page range by setting RangeMode property.
For protected documents, it is also required to provide a password.
The table below contains the full list of properties that can be specified when changing rotation for document pages:
| Name | Description | Comment |
|---|---|---|
| FilePath | The file path in the storage | Required property |
| StorageName | Storage name | Could be omitted for default storage |
| VersionId | File version Id | Useful for storages that support file versioning |
| Password | The password to open file | Should be specified only for password-protected documents |
| Pages | Collection of page numbers to use in a Join operation | The first page should have number 1 |
| StartPageNumber | Start page number | Ignored if Pages collection is not empty |
| EndPageNumber | End page number | Ignored if Pages collection is not empty |
| RangeMode | Page range mode: Even, Odd, All. The default value is All | Ignored if Pages collection is not empty |

SDKs
Using an SDK (API client) is the quickest way for a developer to speed up the development. An SDK takes care of a lot of low-level details of makingRequests and handlingResponses and lets you focus on writing code specific to your particular project. Check out our GitHub repository for a complete list of GroupDocs.Merger Cloud SDKs along with working examples, to get you started in no time. Please check to Get Supported File Formats article to learn how to add an SDK to your project.
