Hi Antoine,

My class and main method are posted below.  It works fine when I just have something like:
 
graph {fill-color: #666666;} 

but when I change it to:
 
graph {fill-mode: image-scaled-ratio-max; fill-image: url('C:/path/to/file.png');}
 
it gives me a solid white background for my graph instead of the image file.  I just now tried and it even works with:

graph {fill-mode: image-scaled; fill-image: url('C:/path/to/file.png');}

For some reason, just the image-scaled-ratio-max doesn't work for me.

Regards,
Keith


public class NYTweetsVisual {

Graph g2;
public NYTweetsVisual() {
g2 = new DefaultGraph("2");
}
public void showDynamicGraph() throws IOException {
FileSource fs = FileSourceFactory.sourceFor("C:/nyTweetLoc1.dgs");
fs.addSink(g2);
System.setProperty("gs.ui.renderer", "org.graphstream.ui.j2dviewer.J2DGraphRenderer");
g2.addAttribute("ui.quality");
g2.addAttribute("ui.antialias");

Hi Keith,

This should work with fill-mode and fill-image as expected. Do you have some example of code to reproduce the error here ?

Antoine

I am able to fill a node with an image but I have not been able to use the same command to fill the graph background with an image.  Do the fill-mode and fill-image commands not work for the graph background?

Regards,
Keith
