[Cuis-dev] scaling an ImageMorph

[Hilaire Fernandes]

Mark, from my understanding what you want to use is the *scale* command 
not the *resize* which are not interchangeable. 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:

  * *scale --> #scale:*
  * *resize --> #morphExtent:
    *

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 
#scale:/#scaleBy: 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
