"There is no need to open the morph in the world and delete it. #imageForm uses its own form and renders the morph onto it."

| image |
image := AlignmentMorph newRow
hResizing: #shrinkWrap;
vResizing: #shrinkWrap;
color: Color gray;
addMorph: (EllipseMorph new color: Color red);
       addMorph: (EllipseMorph new color: Color yellow);
       addMorph: (EllipseMorph new color: Color green);
       imageForm.

image writePNGFileNamed: 'myImage.png'

"there are some export methods in morph which can be used instead of #imageForm and then #writePngFileNamed (#exportAsPNG), which will then prompt you for the file name and location".

Best regards,
Henrik
