Can you display a bitmap with/inside of a sizer?

Good day!

I'm working on a little app to design common emitter amplifiers. I created
a circuit schematic with Eagle and exported it to a PNG file.

I am currently displaying the PNG at a fixed location of the screen with:

    Wx::Event::EVT_PAINT($self, sub {
        my ($self, $event) = @_;
        My $dc = Wx::PaintDC->new($self);
        my $bmp = Wx::Bitmap->new("CEAmpImg.png, wxBITMAP_TYPE_PNG);
        $dc->DrawBitmap($bmp, 150, 50, 1);});

If would be nice if I could blend this in with the sizers that are
controlling the layout of the input and output TextCtrls.

Thanks for your ideas.
