[Newbies] Resizing a form to specific width and height

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
