:warning: DISCONTINUED - Cordova base64ToGallery Plugin

This plugin (based on devgeeks/Canvas2ImagePlugin) allows you to save base64 data as a png image into the device (iOS Photo Library, Android Gallery or WindowsPhone 8 Photo Album).

The plugin is a kind of fork of the solderzzc/Base64ImageSaverPlugin but with a cleaner history (a.k.a: no tags from Canvas2ImagePlugin repo) and a newer iOS implementation.

Alerts

Plugin id - issue #1

In order to be more consistent with the cordova naming convention, since version 2.0 the repository name and the cordova plugin id have changed to cordova-base64-to-gallery.

Please uninstall the old version and reinstall the new one.

cordova-ios > 3.8.0 - issue #3

According to the documentation, NSData+Base64.h class was removed starting from version 4.0.0 of the cordova-ios platform (and it was already deprecated from version 3.8.0).

So, cordova-base64-to-gallery plugin from version 3.0.0 has changed the iOS implementation in order to support the changes in cordova-ios platform.

If you need to support cordova-ios < 3.8.0 please refer to [email protected]. There is also an "old" branch that might have some updates in the future (Android/WP8 fixes or something like that).
