Re^5: Howto convert Image::Grab jpg object to Image::Magick object???

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

Hi This code did the job for me. #get the latest image from the IP camera my $snapshot = new Image::Grab; $snapshot->ua->timeout(5); #sets the timeout (sec) for image::grab (d +efault is 180s) $snapshot->url("$Camera{$key}"); # create the grab object $snapshot->grab; # grab the image mark_blob(my $jpg); # mark as a binary variable $jpg = $snapshot->image; # Convert to Image::Maggick image my $pic = Image::Magick->new(magick=>'jpg'); # create new image obje +ct $pic->BlobToImage($jpg); #convert the grabbed blob image to Image::Ma +gick object [download]	[reply] [d/l]

What is "mark_blob"? It's probably not needed...	[reply]

See the BLOB module. It simply marks the variable as a BLOB. I don't know how the insides of the compiler works (and I am not going to look), but pre-defining the variable type should make the code run faster. Even if it doesn't, at least it should make the code easier to read in the distant future when I come back to modify it.	[reply]
