Sharing screenshot image to Instagram about instagramplugin

[vstirbu]

The general approach for sharing the image when having the file path is to get the file content using the FileSystem API. The key API for getting the content in a form that is compatible with the plugin is FileReader.readAsDataURL.

Can you explain how to do it?

There is a good article on HTML5Rocks on how to use the Filesystem API. Have a look at the Reading a file by name section.

Here's how to do it:
Add org.apache.cordova.file and use this code:

navigator.screenshot.save(function(error,res){
                                         if(error){
                                         console.error(error);
                                         }else{
                                        window.resolveLocalFileSystemURL("file://"+res.filePath, gotFile, fail);
});

function fail(e) {
    console.log("FileSystem Error");
    console.dir(e);
}

function gotFile(fileEntry) {
    fileEntry.file(function(file) {
                   var reader = new FileReader();
                   reader.onloadend = function(e) {
                   Instagram.share(this.result, function (err) {
                                   if (err) {
                                   console.log("not shared insta");
                                   } else {
                                   console.log("shared insta");
                                   }
                                   });
                   }
                   reader.readAsDataURL(file);
                   });
}
