liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf

# Camera Plugin
Prompt the user to take a photo using the camera or pick an image from the gallery. Mobile only.
## Install
There are three general methods of installation that we can recommend.
1. Use crates.io and npm (easiest, and requires you to trust that our publishing pipeline worked)
2. Pull sources directly from Github using git tags / revision hashes (most secure)
3. Git submodule install this repo in your tauri project and then use file protocol to ingest the source (most secure, but inconvenient to use)
Install the Core plugin by adding the following to your `Cargo.toml` file:
```toml
[dependencies]
tauri-plugin-camera = { git = "https://github.com/tauri-apps/plugins-workspace", branch = "feat/camera" }
```
You can install the JavaScript Guest bindings using your preferred JavaScript package manager:
> Note: Since most JavaScript package managers are unable to install packages from git monorepos we provide read-only mirrors of each plugin. This makes installation option 2 more ergonomic to use.
```sh
npm install 'https://gitpkg.now.sh/tauri-apps/plugins-workspace/plugins/camera?feat/camera'
# or
yarn add 'https://gitpkg.now.sh/tauri-apps/plugins-workspace/plugins/camera?feat/camera'
```
**NOT AVAILABLE YET, WILL BE READY WHEN WE MERGE THE BRANCH:**
```sh
pnpm add https://github.com/tauri-apps/tauri-plugin-camera
# or
npm add https://github.com/tauri-apps/tauri-plugin-camera
# or
yarn add https://github.com/tauri-apps/tauri-plugin-camera
```
## Usage
Register the core plugin with Tauri:
`src-tauri/src/lib.rs`
```rust
#[cfg_attr(mobile, tauri::mobile_entry_point)]
pub fn run() {
tauri::Builder::default()
.plugin(tauri_plugin_camera::init())
.run(tauri::generate_context!())
.expect("error while running tauri application");
}
```
Afterwards all the plugin's APIs are available through the JavaScript guest bindings:
```javascript
import { getPhoto } from "tauri-plugin-camera-api";
const image = await getPhoto();
```
### Android
Add the following permissions on the `src-tauri/gen/android/$(APPNAME)/app/src/main/AndroidManifest.xml` file:
```xml
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
```
### iOS
Configure the following properties on `src-tauri/gen/apple/$(APPNAME)_iOS/Info.plist`:
```xml
<key>NSCameraUsageDescription</key>
<string>Description for the camera usage here</string>
<key>NSPhotoLibraryAddUsageDescription</key>
<string>Description for the library add usage here</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>Description for the library usage here</string>
```
