[Pharo-project] System browser in Pharo 1.4
by Olivier Auverlot April 27, 2012

April 27, 2012

Hi, This is probably a stupid question. Why in Pharo 1.4, the system browser does not display classes hierarchically in the column instances / class. Each class is displayed at the same level. It's not easy to read. How to get the same behavior as in previous versions of Pharo ? Best regards Olivier

[Pharo-project] Polymorph (and a few other) changes/fixes
by Gary Chambers April 27, 2012

April 27, 2012

Finally found the time to package out. Have tested a bit after fixing some conflicts. A few minor ones left for DropListMorph as it seems the wrapSelector stuff has changed (and appears broken in 2.0 too). Attached cs and description of changes Regards, Gary

[Pharo-project] more fixes to svg importer
by Igor Stasenko April 27, 2012

April 27, 2012

now its much better.. still there are some parts missing.. mainly those: support for elliptical arcs.. ASEllipse / #ellipticalArc: r xrot: xrot large: large sweep: sweep to: pt .. should add this type of segment to path builder. they are usually approximated either by quad or cubic bezier.. and there is a .java code for it.. just need to port it. Also some svg playing with layers/transparency groups.. to render them correctly a renderer much allocate multiple bitmap buffers to render intermediate layers separately. this is also used for masking etc and of course filters.. not implemented. and no protocol for changing the blit mode yet. -- Best regards, Igor Stasenko.
