Is there a reason you want to write this out as a JPEG file rather than a GIF or PNG? JPEG is a lossy compression scheme and usually does a really bad job of handling sharp borders, which includes things like text on a solid background. (Also, you mention transparency, but I don't believe JPEGs support such a concept.)
As it happens, I was experimenting with the Annotate method myself just yesterday. This code worked fine for me:
my $image = Image::Magick->new;
$image->Set(size=>'300x300');
$image->ReadImage('xc:white');
$image->Annotate(
font => 'c:/windows/fonts/arial.ttf',
pointsize => 24,
fill => 'green',
text => "Image::Magick\nrocks dude",
x => 100,
y => 100
);
$image->Write('bigfont.gif');
I'm not sure what might be wrong with your code, but I wonder if it could have anything to do with the font string you're passing to the Annotate method. For testing purposes, I would consider hardcoding the name of a font that you know is there.
Hope this helps...
