Summary0000134: Strange colors from this node-only graph
Description



neato -Tpng c:\temp\graphdesc.dot -o c:\temp\blah.png



The above command, when run on the dot input included below, creates
a set of nodes where the node titled "CaseSelector" is a funky shade
of light pink instead of the purple it is supposed to be. All other
nodes are also in incorrect colors, but this is the most obvious.
Deleting either or both of the first two nodes "ArraySubset" or
"InitializeArray" corrects the problem and all nodes draw in the right
colors.
Steps To Reproduce

}
Additional Information

[ellson] I think you're hitting the 256 color limitation of the indexed
color scheme that is used in GD, originally for GIF images. The colors
get used quickly because of anti-aliased font strings. Each new combo
of forground and background color uses 6 color indexes.

I was expecting this restriction to have gone with the truecolor png support
from gd-2.0.6 that we're using in latest CVS sources, but the effect is
still there, so I'm going to leave this problem open for now and I will
investigate further.
