 Hi,

Normally CPAN documentation is quite good.

However I'm having some problems with ImageMagick.

Could anybody point me to some good concise documentation.

Reading the Imagemagick documentation and guestimating how to pass the
same parameters to the perl equivalemt is not always simple:

Example:

Assume following ImageMagic command:

convert -size 64x64 xc:transparent -pointsize 10 -draw "text 0,20
'hello'" test.png


I'd like to do the same in perl:

my $g = Image::Magick->new;
$g->Set(size=>"64x64");
$g->ReadImage('xc:transparent');
$g->Draw( primitive => 'text', BUT_WHAT_IS_THE_SYNTAX_HERE_???? );
$g->Write("test.png");

and don't really know where to look.


Any hint / document is welcome


bye

N

I know the problem.
http://imagemagick.org/script/perl-magick.php
At least you find the possible parameters there.

Thanks a lot Frank,


That's also the one, which I found and tried to understand.

Any perl script displaying a text with the Image::Magick::Draw method
would solve my current problem.

Perhaps I manage to google for an example, though I didn't get a useful
hit so far

There is a security image (CAPTCHA) module - GD::SecurityImage - on CPAN
that can use Image::Magick. I am not sure if that has a good example of
what you want to achieve though.

Hope you're using the right search tool in google for code-search,
e.g. like this:

http://www.google.com/codesearch?hl=3Den&q=3D%22use+Image%3A%3AMagick%22+%22=
-%3EAnnotate%22+text%5Cs%2A%3D%3E+lang:perl
