Add typescript bindings

[SerialVelocity]

Hey,

Not sure if this is still maintained (works great for me!). Is it possible to add typescript bindings for this library? They need to be checked into https://github.com/DefinitelyTyped/DefinitelyTyped

Cheers, SerialVelocity

@sidorares thanks, but it undefined wit you code. why we use unpack('c') and not capital C ?

[vtolstov]

with C i get lenght and it not undefined..

[vtolstov]

and i check and first rect is the png image =)

[vtolstov]

but next frmae i don't know' wireshark can't determine encoding. i think that qemu send another frame with this encoding.... but i can't get spec about it.

[vtolstov]

hm but it have garbage from beggining..

[vtolstov]

ah.. we need to skip from stream needed bytes that contains len =)

[vtolstov]

i'm stuck to get propet png (from beginning) i need to skip from stream 8 bytes =(

[vtolstov]

@sidorares do you have some thinks about this?
