Retreiving ppi and print size from jpg or gif files

[blaine]

I've been searching around trying to find a package that would let me
find out the Pixels Per Inch (ppi), print size and non-compressed file
size of and image. However I have not had any luck yet.

Does anyone know where I can get such a package or how to code this?

Ideally it would work something like the following:

my $obj = new ImageInfo($image);
my $ppi = $obj->ppi();
my $printWidth = $obj->printWidth();
my $fileSize = $obj->uncompressedFileSize();

Look forward to your response.

What KIND of image? Ah, jpeg or GIF. Don't put important info about
your problem *only* in the header. First stop for anyone looking for
a package: http://search.cpan.org. A search on jpeg turned up
288 packages. A search on gif turned up 535. I expect that something
in there will meet your needs.

However I have not had any luck yet.

my $obj = new ImageInfo($image);
my $ppi = $obj->ppi();
my $printWidth = $obj->printWidth();

Look forward to your response.

By the way. Reposting your message because you didn't get a response in
nineteen minutes is not a good way to endear you to the group.
