PlatformMacOSOS XOS Version10.7
Summary0002154: Edge len attribute ignored in 2.28 and 2.29
DescriptionUsing neato to draw a dot file the edge length attribute is ignored in versions 2.28 and 2.29, but was working well in 2.26.

I have only tried using versions >2.26 on OS X 10.7, but have previously used 2.26 on OS X 10.6
Steps To ReproduceCreate graph in dot format with edge length specified using len attribute. Problem occurs with len attribute specified on a global or per edge basis.
TagsNo tags attached.

Please provide an input graph and the bad output you get. I tried a few examples with edge lens set and 2.28 neato works fine.

see attached dot file and the output obtained with neato, e.g.

neato -K neato -o test.pdf -Tpdf test.dot

different versions provided 2.26 and 2.28

Until 2.28, overlap=false was interpreted as overlap=voronoi. With 2.28, overlap=false became overlap=prism, a much better algorithm for removing overlaps. However, prism also does a compaction phase, which is why the new drawing is smaller.

To get the old behavior, use overlap=voronoi explicitly.
