Image::Magick and JPEG Compression

[OzzyOsbourne]

I loaded the Image::Magick module, and wanted to create a compressed JPEG. I thought this would be easy, but I'm missing something. I can write JPEGs, just not compressed ones.

$image->Write(filename=>$file,compression=>'JPEG',quality=>'10')

I checked the docs, and I checked google, but I can't seem to find a straight answer on what may be going wrong. Is there a module that I'm missing to get this to work on a win2k box?

Thanks in advance.

I might be missing something myself, but isn't JPEG a compressed format itself? If that were the case, wouldn't fiddling with the quality parameter result in different levels of compression?

A quick scan of google didn't show me anything to set "jpeg" apart from "compressed jpeg" - most links were describing jpegs as compressed when compared to formats such as bitmap.

What do you get for an error? Try:

my $x = $image->Write(filename=>$file,compression=>'JPEG',quality=>'10
+');
warn "$x" if "$x";
$x =~ /(\d+)/;
print "ERROR: [$1]\n";

You can get the error codes (as well as the above error example) here:

This might be useful too, as you're using Win2K:
