[magick-users] FW: How to set attribute in PerlMagick about -density option in ImageMagick ?

[신하얀]

Hi, there
I received the solution from Pete.
Here is solution
====================================
Hi,

Try this:

Use Image::Magick;
my $image = Image::Magick->new();
$image->Set(units=>1);
$image->Set(density=>110);   <== set attribute before read file 
$image->Read($ps_file);
$image->Rotate(degrees=>-90);
$image->Trim();
$image->Write($gif_file);


Best Wishes
Pete
==================================

Your perl script seems to work for me with ImageMagick-6.4.3,
and the PerlMagick that comes with it.  Maybe if you could
post a small ps file you are working with, and what you see as
output.
