R: Edge lines are waving in metafiles #78

Closed ko-ichi-h closed 9 years ago

ko-ichi-h commented 9 years ago

With recent versions (0.7.1 and 0.7.0) of igraph R package, I find that edge lines are waving in saved metafiles. Please see the “before” figure of the attached image. igraph2

It can be fixed like the “after” figure by changing the following line in the “igraph.Arrows” function.

if (is.logical(curved) && all(!curved)) {

I changed this line as follows to make the “after” figure.

if ( (is.logical(curved) && all(!curved)) || all(!curved) ) {

BTW, thank you very much for developing such a nice software!

Well, the real fix would be to draw straight lines instead of Bezier curves for edges with curved=0.
