To do so I only need to change the parent of the DrGDrawable class to VectorGraphicsPasteUpMorph. Easy. I read your hack, it adds one message send per rendered morphs. I don't have strong opinion on that. <img moz-do-not-send="false" src="cid:part1.93B55170.7F913D8D@drgeo.eu" title="DrGeo on VectorGraphics canvas" alt="" width="590" height="551"> You can observe the lines are blurred and the colour is not right. The lines should be black and they are too thick for a one pixel width line. Some lines are black because there are several segments in top of each other. Adding a StringMorph will set Cuis in an infinite loop scenario without way to escape (Alt+[.] did not work): <pre>| c | c _ VectorGraphicsPasteUpMorph new openInWorld. c addMorph: (StringMorph new contents: 'Hello') </pre> Thanks!
