in thread Howto convert Image::Grab jpg object to Image::Magick object???

Do I need to use Blobs??

Did you try the code I posted? As far as I can tell from the docs, this should be all you need to get the $imgdata I showed in my other post:

use Image::Grab qw/grab/;

my $imgdata = grab('http://upload.wikimedia.org/wikipedia/commons/1/1a
+/Image_upload_test.jpg');
# - or -
my $pic = Image::Grab->new;
$pic->url('http://upload.wikimedia.org/wikipedia/commons/1/1a/Image_up
+load_test.jpg')
$pic->grab;
my $imgdata = $pic->image;

    Hi

    I found this code sample that converts from GD to Image::Magick objects. It is like I want to do and it should work between any objects.

    Haukex, I will give your code a go. 

    #!/user/bin/perl
use strict;
use Image::Magick;
use GD;
# First read an image with Image::Magick

my $im = new Image::Magick;
my $status = $im->Read('monkey.png');
if ($status) {
  die "$Status!";
}

# Convert to a blob and hand off to GD

my @blobs = $im->ImageToBlob();
my $gd = GD::Image->newFromPngData($blobs[0]);
my $red = $gd->colorAllocate(255,0,0);

# Outline in Red

$dg->rectangle(0,0, (map {$_-1} $gd-?getBounds), $red);

# There and back again
my $im2 = new Image::Magick;
$im2->BlobToImage($gd->png());
$im2->Write('png:monkeyout.png');

      For this example code, I'm not sure if you need the conversion to GD, since Image::Magick supports a ->Draw command. Here's another untested copy-n-paste from the docs you could try:

      $image->Draw(stroke=>'red', primitive=>'rectangle', points=>20,20 100,
+100');

      Where $image is an Image::Magick object.

        Hi

        The GD is irrelevant in this case but it gives me a template to follow when applied to Image::Get and Image::Magick. I had found your docs reference but it doesn't show me how to pass an image from one object to a different type of object.

        Thanks for your time looking at this
