Unable to Align two figures

Question

I have two figures of slightly different sizes. So I'm unable to align them vertically, as shown in the figure.

I'm using the following code.

\begin{figure}[h]
       \centering
       \includegraphics[width=2.8cm]{Fig1.pdf}
        \includegraphics[width=3.2cm]{Fig2.pdf}
       \caption{This is the caption.}
   \end{figure}

The problem is that Fig2 has an in-picture label, so to make them look of the same size, I have used width=3.2cm for Fig2 and width=2.8 for Fig1. So is there any way to align them at the top? For example, by moving only the left figure a little up or right fig a little down.

Answer 1

If you try with this it works?

\begin{figure}[h]
      \centering
      \begin{minipage}[b]{0.4\textwidth}
        \includegraphics[width=2.8cm]{Fig1.pdf}
      \end{minipage}
      \hfill
      \begin{minipage}[b]{0.4\textwidth}
        \includegraphics[width=3.2cm]{Fig2.pdf}
       \caption{This is the caption.}  
      \end{minipage}
    \caption{bla bla}
    \end{figure}

If not try to play with the command "width".
