raw image data?

23skiddoo has asked for the wisdom of the Perl Monks concerning the following question:

Greetings, monks. I am working with the Net::Twitter module to create a little script to send tweets of what I am listening to on Amarok. I also want to change my Twitter image with the currently playing album cover. The pod says that the method update_profile_image() expects "raw image data, not a pathname or URL to the image." Can someone point me to a module that will covert a local file to a thing that will work? I looked at Imager and Image::Magick but could not figure it out. Thanks! Eddie

UPDATE: I got on #net-twitter on irc.perl.org and spoke with the author. It seems that my code is solid, but the reason it is failing is that twitter is simply too busy. Apparently, when their servers get overloaded, image uploads from the web interface or the API tend to fail.

Thanks to everyone that helped me out!

That means it's expecting the contents of the file. `my $raw_image_data = do { open(my $fh, '<:raw:perlio', $image_qfn) or die("Can't open image file \"$image_qfn\": $!\n); local $/; <$fh>; };` [download]	[reply] [d/l]

Hmm... I tried a similar route before coming to the monastery: `open my $fh, "<", $image_file or die "Can't open $image_file: $!"; my $raw = <$fh>;` [download] Which I believe is the same as the slurp() function mentioned above. It failed. I tried your code too, with the same failure. The file has to be under 700K and my test files have definitely been below that. There must be something else going on. Unfortunately the error messages returned don't provide much help. Thanks for your help! fnord	[reply] [d/l]

Did you binmode the filehandle? --- It's all fine and dandy until someone has to look at the code.	[reply]
