Rezize image when printing, what to do ?

[Frank Jacobsen]

I get the data to a image from a backend system from the mainframe system, and displays this on a html page.

My problem is, when i print this image, how do i rezise it to fit into the paper on a printer ?.

I have tried to resize it on the funtion, but nothing Seems to work …

Any good ide´as out there somewhere ?

  
// Gets data from backend system, from a servlet.

byte[] img = getImageFromHost(user, id);

//header stuff
res.setContentType("image/png");
res.setContentLength(img.length);
					
			
//send it
ServletOutputStream out = res.getOutputStream();
out.write(img);
out.flush();
out.close();


// Html function to print image.

function printPic(picURL){
billede = window.open(picURL, "billede", "toolbar=no,scrollbars=yes,location=no,resizable=yes,height=600,width=1000,left=150,top=150,screenX=150,screenY=150");
billede.focus();
billede.print();
}

If you are just returning the image from the server and nothing else in the pop up window, there is not much you can do about it.

But i have the possibility to do something in the servlet, but what can I do ?

Resize it on the server then. And stream back the resized image.
