[TypeError: Object #<PNGStream> has no method 'destroy']

[kilianc]

Stream interface not fully implemented.

99% sure Stream's prototype has no destroy

[tj]

nope

[tj]

wtf.. ok the node docs mention it just fine, this is part of why streams are garbage, just assuming every stream-like thing happens to implement the correct interface

[mitar]

There is also no pause.

OK. A simple workaround:

var through = require('through');
var wellBehavedStream = canvasElement.pngStream().pipe(through());

So you just pipe it through through() and it will make it work.

From the docs and discussion on SO it seems like streams don't actually provide a .destroy method, although fs.readStream happens to.

See more notes in #740.

Fixed in 8b5dc05 I think. (Definitely fixed, but not positive it was that commit.)
