Nice work, Nicolai! Brick does not work - It uses some of Canvas' private api, and it is > difficult to provide this with Athens.
I will try to fix it when have time. Actually there was no need to use that private api, I just was too lazy to do slightly more math when converting global coordinates to local ones in drawing methods :) Cheers, Alex On Fri, Jan 23, 2015 at 5:40 PM, Nicolai Hess <nicolaih...@web.de> wrote: > > > 2015-01-10 13:18 GMT+01:00 Nicolai Hess <nicolaih...@web.de>: > >> >> I think I got the MorphTreeTransformMorph now working, need to clean up >> the code >> and maybe I 'll upload this to the athens repository. >> >> nicolai >> >> >> > > I don't know how often I thought "I got this working", but NOW I think I > got this morphic transformation working :) > > I give up to use the AthensTextRenderer classes, they aren't implemented > fully, to much work for me to do this. > Instead, I just subclass the DisplayScanner and reimplemented all > Canvas-draw-methods with athens-drawing-methods. > > Still some morphs aren't "ported", but they use some magic.
