Get graphics from VisualizationComponent rapidminer
Contributor II
Hi,
How to get graphics or image from visualization component??
i have visualization component the same i am passing to JFrame tree is displaying in standalone app.
but in WebApplications it is not coming as Jframe will work for standalone apps.
Component visualizationComponent = gr.getVisualizationComponent(model, ioResult);
visualizationComponent .getGraph()...............>returns null even though visualization.isDisplayable() returns true.
if i use renderer where it will render ?
i want to get the tree and display in Application by setting some variable.
Thanks in advance

Renderer renderer = RendererService.createRenderer(result, "Graph View");
Reportable reportable = renderer.createReportable(result, dummy, imgWidth, imgHeight);
pls correct me if i am wrong
the BufferedImage img i nee to get from rapidminer component
final BufferedImage img = new BufferedImage(imgWidth, imgHeight, BufferedImage.TYPE_INT_RGB);
Graphics2D graphics = (Graphics2D) img.getGraphics();
graphics.setColor(Color.WHITE);
graphics.fillRect(0, 0, imgWidth, imgHeight);
double scale = Math.min((double) imgWidth / (double) preferredWidth, (double) imgHeight / (double) preferredHeight);
graphics.scale(scale, scale);
and i have a query on redering
renderable.render(graphics, preferredWidth, preferredHeight);
where it will render the tree??
Thanks a lot for bearing me
my codeblock from the linked thread paints the tree on any given Graphics object. Please consult Google for details on how to use the graphics context in Java.
