Re: Tk::Photo->data(-format) support ?

Strange thing is the Tk Widget Demo loads some gif files (earth.gif and 
earthris.gif) for the
Alpha Channel Compositing demo.  It doesn't specify the file type, it 
just opens it:

    my $i1 = $mw->Photo( -file => Tk->findINC( 'demos/images/earth.gif' 
) );
    my $i2 = $mw->Photo( -file => Tk->findINC( 
'demos/images/earthris.gif' ) );

Are you sure the binary data is correct?  What if you tried dumping that 
to a file
with a .gif extension and loading it?

Have you tried opening an existing GIF file to see if that works with 
your version?
