Hi Antoine,

Thank you so much for your help.  I will download the new jar files from git. :-)

Regards,

Keith

Hi Keith,

I spotted the bug, but I am too ashamed by the error to tell you what it was :-) It is corrected and pulled on git. I can send you a new gs-ui jar along with a new gs-core jar (the two have changed) if you wish.

Regards,

Antoine

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");

g2.addAttribute("ui.stylesheet", "graph {fill-mode: image-scaled-ratio-max; fill-image: url('C:/path/to/file.png');} " +

"node {size: 3px; fill-mode: dyn-plain; " +

"fill-color: white, yellow, red, blue, black; text-visibility-mode: hidden;} " +

"node.tracker {size: 15px; fill-color: black;} " +

"node.tracker2 {size: 15px; fill-color: red;}");

g2.display(false);

try {

fs.begin("C:/nyTweetLoc1.dgs");

while (fs.nextEvents()) {

try {

Thread.sleep(10);

}

catch(Exception e) {

e.printStackTrace();

}

}

} catch( IOException e) {

e.printStackTrace();

}

try {

fs.end();

} catch( IOException e) {

e.printStackTrace();

} finally {

fs.removeSink(g2);

}

}

public static void main(String[] args) throws IOException {

NYTweetsVisual graph = new NYTweetsVisual();

graph.showDynamicGraph();

}

}

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 ?

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
