<p>Hi Juan</p>
<p>the solution you provide is good as it is a good workaround.
Looks a bit clumsy however constructing two ImageMorph objects
as you start with a jpg form. And Mark wants to include this
example in a booklet about Morphic.<br>

No, #defaultForm doesn't create an ImageMorph. It just answers a
sample Form. <br>

<p>Reading a JPG picture into an instance of Form, scaling it and
constructing an ImageMorph object works fine as example [1b] in
this<br>

<p>So I'd like to draw your attention that on the fact that
shrinking an ImageMorph object does not work as example 2 in the
same thread shows.</p>
<p>The solution to make ImageMorph>>shrinkBy: work
provided by Weslleymberg Lisboa is shown in this mail</p>

<pre>Current ImageMorph>>minimumExtent implementation
````
minimumExtent
^ image extent + (2 * self interiorOrigin)

Weslleymberg proposal for ImageMorph>>minimumExtent

minimumExtent

<p>Seems to be pretty straightforward though it took him a
considerable time to come up this it. What do you think about
this solution? Are there side-effects about this fix? If not I
suggest that it should be included.<br>

The problem was not in ImageMorph. There was a bug in Layout. Aux
method #minimumLayoutExtent: should work in owner's coordinates,
just like #fitInto: . I just pushed a fix that does that.<br>
<br>
You can try this, and resize the Layout.:<br>
A bettern implementation of ImageMorph could behave more like the
Star and the Smiley, where the Layout resize can rescale them.<br>

Just scale the form prior to using it: `(ImageMorph newWith:
(ImageMorph defaultForm magnifyBy: 0.5)) openInWorld.`<br>
<br>
A new kind of morph that is not part of the BoxMorph hierarchy
would give better flexibility, by not using an `extent` instance
variable. But may be the simplest solution works for you.<br>
