Title: Shift in image maps
Submitter: Emden R. Gansner
Date: Mon Jul 15 13:42:16 2002
Subsys: Dot
Version: 1.8.8
System: *-*-
Severity: minor
Problem:
The coordinates produced by imap/cmap appear to have shifted down and to the right sometime after 1.8.5. In the graph below, the earlier release has (14,14)(86,62) as the coordinates of n1 The newer releases have (19,30)(91,78). The gif output hasn't changed. And using the maps in web pages seems to indicate that the earlier coordinates are correct.
Input: 
digraph x {
         n1 [ color = "red", URL="n1" ];
         n2 [ color = "green", URL="n2"];
         n1 -> n2 [ color = "blue", URL="e1" ];
         n3 [ color = "pink", URL="n3" ];
}
Comments:
[ellson] The problem is that dot was generating incorrect maps, but doxygen was compensating. graphviz-1.8.9 generates maps that conform to the W3C spec.

I discussed this with the doxygen author. My understanding (but not personally verified) is that the new release of doxygen will have a fix that will make it compatible with 1.8.5 and 1.8.9 and later versions of graphviz.
