<div>Dear all,</div>
<div> </div>
<div>I'd love to receive any kind of advice on the following issue:</div>
<div> </div>
<div>I have access to some image data via calls to a function (passing the coordinates of every pixel as a parameter). Although stepping through the whole input image and storing it in a custom created image object could do the job, I'd like not to duplicate resources. That's why I am looking for a way to create an image whose pixels are evaluated via a function call, is that possible (not from scratch)?</div>
<div> </div>
<div>Thanks in advance.</div>
