PerlMagick (a perl interface to the
ImageMagick tool)
is just what you need. It is the swiss-army knife
of perl image manipulation libraries. PerlMagick comes with the
standard ImageMagic distribution. ImageMagick can handle
many image formats including: BMP, GIF, PNG, JPG (many more, see
the full list).
The actual PerlMagick code is pretty simple to use in your application:
use Image::Magick;
my $im=new Image::Magick;
$im->Read($fname);
$im->Annotate(text=>'some text');
$im->Set(format=>'Joint Photographic Experts Group JFIF format');
$im->Write();
PerlMagick can also do many "photoshop-type" editing
effects (Crop, Scale, Blur, Despeckle, etc). It is big
but I have yet to fins a more powerful image manipulation
tool under Perl.
