Hi embers,  
I receive from a websocket server a jpeg from a canvas on a web page:  
`var imgData = canvas.toDataURL("image/jpeg"); window.socket.emit('canvas', imgData);`

In my Cinder app, the message is received as a string, see screen capture below:

How can I convert this string to a texture?  
Thank you for any hint.

Hi,

use Cinder’s [base64](https://github.com/cinder/Cinder/search?utf8=%E2%9C%93&q=base64) functions to convert the data to a JPEG file again, then use `loadImage` to load it from memory.
