I am new to TkiZ. I am trying to create the below Input and Output nodes of Specification and Description Language

enter image description here

Is there an existing \node or \tikzstyle to achieve the above in the TIKZ package?

Tried to read the below:


Seem not readily available.

TikZ shapes are extremely hard to create. I do not know if "chamfered rectangle" could be manipulated to get the two nodes.

Could you guide me on this.


Thanks to Sigur and Zarko.

"Signal" is what I was been looking for. Implimented the below way and it worked like a charm. Consider this as solved.

\tikzstyle{output1} = [signal, signal from=nowhere, signal to=east, minimum width=3cm, minimum height=1cm, text centered, draw=black, fill=blue!30]

\tikzstyle{input1} = [signal, signal from=east, signal to=nowhere, minimum width=3cm, minimum height=1cm, text centered, draw=black, fill=red!30]

    See TikZ manual, pp.703 -- 704 'shape signal'. – Zarko Jan 7 '15 at 0:36
