CouchAttachments has no access to attachments if not public

[lpatiny]

I don't know how to send credential so that couch attachments can load attachment of a non public view

[stropitek]

I always send credentials, it should work on private views

[lpatiny]

You are right. In fact it is when I load the image using image-js. I just used the URL so I don't know what should I do.

With couchdb attachment you can get the data content as a Blob by doing

cdb.get(attachmentName, {responseType: 'blob'})

You can then convert the Blob to a dataUrl before passing it to image-js

function blobToDataURL(blob, callback) {
    var a = new FileReader();
    a.onload = function(e) {callback(e.target.result);}
    a.readAsDataURL(blob);
}

Not an easy solution ... how we could forward credential ? Can it be in the url somehow ?

You have two options:

• Download the image data as an ArrayBuffer ({responseType: 'arraybuffer'}) and then pass it to Image.load
• Add {withCredentials: true} to the Image.load options

Ok, didn't know withCredentials was an option in image-js
