Why not have it write all the filetypes to a ramfile first:

my %sizes; for my $type ( Imager->write_types ) { open my $ramFH, '>:raw', \$buffer; $im->write( fh => $ramFH, type => $type ); $sizes{ length $buffer } = $type; } ## Pick type of smallest my $filetype = $sizes{ (sort{ $a <=> $b } keys %sizes)[0] }; ## write to real file ...

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
