best way to store binary image data in a variable using image magick

[Jack]

Hi all,

Just wanted to know the code for doin this, such that I can use the
variable for doing other kinds of methods against it..

I tried this, and I can printout the binary data, but I am finding you
can assign the image data to a variable for further processing.. any
ideas ? I noticed that this line: $img->Write('jpg:-'); actually
displayed the image data, but how do I assign that binary data to a
variable ??

use Image::Magick;
my $img = new Image::Magick;
$x= $img->Read("c:\\tmp\\ean81.bmp");

## doesnt work: $img->Write('$temp');

Hi forgot to say when I print $img or $x I get ---
Image::Magick=ARRAY(0x2260a4)
