DOT_NODE_ATTR ignore color

[samrrr]

Describe the bug
DOT_NODE_ATTR ignore color
Way to change fill color fails.
DOT_NODE_ATTR = "color=red, fillcolor=gray20" ignored

Screenshots

To Reproduce
Set DOT_NODE_ATTR to
color=red, fillcolor=gray20
Generate and open graph png from Graphviz.

Expected behavior
Not white ellipses in generated png.

Version
1.10.0

Stack trace

Additional context

Generated .dot files contains color override from hardcoded colors like this:

t << " color=\"steelblue1\" fontcolor=\"steelblue1\"];\n";

fillcolor=\"white\",style=\"filled\"

From the screenshot, what does it represent?, it is not detectable what and where the problem might be. To be able to reproduce the issue:

• Can you please attach a, small, self contained example (source+configuration file in a, compressed, tar or zip file!) that allows us to reproduce the problem? Please don't add external links as they might not be persistent (also references to GitHub repositories are considered non persistent).

I did some small tests to represent a bit the image that is used in the issue:

aa,h

/// \file


class base
{
};
class variant: public base
{
};
class vector: public base
{
};

Doxyfile

QUIET = YES
HAVE_DOT = YES
DOT_CLEANUP = NO
DOT_NODE_ATTR = "color=\"red\", fillcolor=\"green\""
DOT_EDGE_ATTR = "color=\"blue\", fillcolor=\"yellow\""

Without the DOT_*_ATTR this gives:

and with the settings:

When looking at the respective *.dot files we see:

Without the settings (html_org/classbase__inherit__graph.dot):

digraph "base"
{
 // LATEX_PDF_SIZE
  bgcolor="transparent";
  edge [fontname=Helvetica,fontsize=10,labelfontname=Helvetica,labelfontsize=10];
  node [fontname=Helvetica,fontsize=10,shape=box,height=0.2,width=0.4];
  Node1 [id="Node000001",label="base",height=0.2,width=0.4,color="gray40", fillcolor="grey60", style="filled", fontcolor="black",tooltip=" "];
  Node1 -> Node2 [id="edge1_Node000001_Node000002",dir="back",color="steelblue1",style="solid",tooltip=" "];
  Node2 [id="Node000002",label="variant",height=0.2,width=0.4,color="grey75", fillcolor="white", style="filled",URL="$classvariant.html",tooltip=" "];
  Node1 -> Node3 [id="edge2_Node000001_Node000003",dir="back",color="steelblue1",style="solid",tooltip=" "];
  Node3 [id="Node000003",label="vector",height=0.2,width=0.4,color="grey75", fillcolor="white", style="filled",URL="$classvector.html",tooltip=" "];
}

with the settings (html_adj/classbase__inherit__graph.dot):

digraph "base"
{
 // LATEX_PDF_SIZE
  bgcolor="transparent";
  edge [fontname=Helvetica,fontsize=10,color="blue", fillcolor="yellow"];
  node [fontname=Helvetica,fontsize=10,color="red", fillcolor="green"];
  Node1 [id="Node000001",label="base",height=0.2,width=0.4,color="gray40", fillcolor="grey60", style="filled", fontcolor="black",tooltip=" "];
  Node1 -> Node2 [id="edge1_Node000001_Node000002",dir="back",color="steelblue1",style="solid",tooltip=" "];
  Node2 [id="Node000002",label="variant",height=0.2,width=0.4,color="grey75", fillcolor="white", style="filled",URL="$classvariant.html",tooltip=" "];
  Node1 -> Node3 [id="edge2_Node000001_Node000003",dir="back",color="steelblue1",style="solid",tooltip=" "];
  Node3 [id="Node000003",label="vector",height=0.2,width=0.4,color="grey75", fillcolor="white", style="filled",URL="$classvector.html",tooltip=" "];
}

So the difference is:

5,6c5,6
<   edge [fontname=Helvetica,fontsize=10,labelfontname=Helvetica,labelfontsize=10];
<   node [fontname=Helvetica,fontsize=10,shape=box,height=0.2,width=0.4];
---
>   edge [fontname=Helvetica,fontsize=10,color="blue", fillcolor="yellow"];
>   node [fontname=Helvetica,fontsize=10,color="red", fillcolor="green"];

The description with DOT_COMMON_ATTR only speaks of things like fonts etc. but not about colors of edges / nodes and I think for good reason.
The colors of nodes and edges have different meanings depending on their tasks and visibility. When these settings would be overruled this extra information is lost.
