Matthias,
If you have a 3.9 or later image look at ThumbnailImageMorph>>newThumbnail: for
details.
In building that I created a Point>scaleTo:(anExtent) method which returns a
scale factor
for the proper reduction of the receiving extent. It preserves the aspect ratio
up to a certain limit
then it will squash things a bit.
Any morph can have a snapshot taken via Shift-clicking on the Viewer handle (
The Cyan handle with the eyeball icon ).
Thumbnails can be shrunk or enlarged. And their red menu allows you to select a
pop-up option.
The pop-up option shows the original image while the mouse is held down on top
of the thumbnail.
I got the idea from Scott Wallace who may be better known for the Universe
Package System.
You may find the thumbnails are all you need.
Yours in curiosity and service, --Jerome Peace
