|
* Problems can be found under Windows **and** Linux (mainly when drawing arcs)

2011-09-30 18:15:37 +00:00

|
* Currently (feb 2009) there are overflow problems when drawing solid (filled)
|
|
|
|
* polygons under linux without clipping

2009-11-23 15:16:50 +00:00

2011-09-30 18:15:37 +00:00
|
|
|
* KiCad or wxWidgets) are fixed by testing how are drawn complex lines arcs

2009-11-23 15:16:50 +00:00
