Example 1 with ImagePanel

use of annis.libgui.ImagePanel in project ANNIS by korpling.

the class AbstractImageVisualizer method createComponent.

@Override
public ImagePanel createComponent(final VisualizerInput visInput, VisualizationToggle visToggle) {
    final ByteArrayOutputStream out = new ByteArrayOutputStream();
    writeOutput(visInput, out);
    String fileName = "vis_" + UUID.randomUUID().toString() + ".png";
    StreamResource resource = new StreamResource(new StreamResource.StreamSource() {

        @Override
        public InputStream getStream() {
            return new ByteArrayInputStream(out.toByteArray());
        }
    }, fileName);
    Embedded emb = new Embedded("", resource);
    emb.setMimeType(getContentType());
    emb.setSizeUndefined();
    emb.setStandby("loading image");
    emb.setAlternateText("Visualization of the result");
    return new ImagePanel(emb);
}
