SaveImage

This plugin allows you to save local JPEG image files to the iOS Camera Roll/Photo Library or Android Gallery. Other image mime types are currently not supported. The image file to be saved to the Library/Gallery must be available on the device.

The plugin is based on code seen in several other existing plugins:

  1. Canvas2ImagePlugin (https://github.com/devgeeks/Canvas2ImagePlugin) by Tommy-Carlos Williams (https://github.com/devgeeks)
  2. ImgDownloader (https://github.com/Nomia/ImgDownloader) by "Nomia" (https://github.com/Nomia)
  3. cordova-camera-roll (https://github.com/driftyco/cordova-camera-roll) by Max Lynch (https://github.com/mlynch)

Thanks to all of the above mentioned authors for sharing their code openly.

iOS Quirks

Since iOS 10 it's mandatory to provide an usage description in the info.plist if trying to access privacy-sensitive data. When the system prompts the user to allow access, this usage description string will displayed as part of the permission dialog box, but if you didn't provide the usage description, the app will crash before showing the dialog. Also, Apple will reject apps that access private data but don't provide an usage description.

This plugins requires the following usage descriptions:

  • NSCameraUsageDescription specifies the reason for your app to access the device's camera.
  • NSPhotoLibraryUsageDescription specifies the reason for your app to access the user's photo library.
  • NSPhotoLibraryAddUsageDescription specifies the reason for your app to get write-only access to the user's photo library

To add these entries into the info.plist, you can use the edit-config tag in the config.xml like this:

<edit-config target="NSCameraUsageDescription" file="*-Info.plist" mode="merge">
    <string>need camera access to take pictures</string>
</edit-config>

<edit-config target="NSPhotoLibraryUsageDescription" file="*-Info.plist" mode="merge">
    <string>need to photo library access to get pictures from there</string>
</edit-config>

<edit-config target="NSLocationWhenInUseUsageDescription" file="*-Info.plist" mode="merge">
    <string>need location access to find things nearby</string>
</edit-config>

<edit-config target="NSPhotoLibraryAddUsageDescription" file="*-Info.plist" mode="merge">
    <string>need to photo library access to save pictures there</string>
</edit-config>
