This is the blue icon in the image morph. Only for non PlacedMorph, resize will behave as scale but because there is not notion of extent, so resize does not make sense in that respect. This halo's icon translate to messages: <ul> <li>scale --> #scale:</li> <li>resize --> #morphExtent: </li> </ul> If you want a different behavior, you need to subclass ImageMorph, which make sense in that circumstance. You want the form to be recomputed at each morphExtent to fill the space in ox or oy axes? It will be more computer intensive and will have to remember also the original Form otherwise you may end with a one pixel Form. But I suspect using the #<a class="moz-txt-link-freetext" href="scale:/#scaleBy">scale:/#scaleBy</a>: message is just what you want. Look at the code of ImageMorph and you will understand its intend. Open an inspector and play a bit with your image morph: self scale: 1.5 self color: color red self borderWidth: 5 self borderColor: Color black <img src="cid:part1.tj0nOom8.LCkvQFvh@free.fr" alt=""> <pre class="moz-signature" cols="72">-- <a class="moz-txt-link-freetext" href="http://mamot.fr/@drgeo">http://mamot.fr/@drgeo</a></pre> </body> </html>
