I have been working on a script which looks for gaps a in numbered series of TIFF files. In order for this to work, I need to be able to identify how many pages there are in any given TIFF. This is the code I'm using: 
sub pageCount {
    my $FILE = shift;
    my $IMAGE = Image::Magick -> new();
    $IMAGE -> Read( $FILE );
    my $PAGECOUNT = $#$IMAGE+1;
    undef $IMAGE;

    return( $PAGECOUNT );
}

My problem is that this method forces me to read each TIFF file. These TIFF files are large enough that this subroutine is too slow to be useful. Is anyone aware of a different, i.e. faster, way to obtain a page count on a multipage image?
