Examples with GraphMetrics org.graphstream.ui.view.util.GraphMetrics used on opensource projects

Example 6 with GraphMetrics

use of org.graphstream.ui.view.util.GraphMetrics in project gs-ui-javafx by graphstream.

the class GraphBackgroundRenderer method strokeGraph.

private void strokeGraph(Backend bck, DefaultCamera2D camera) {
    GraphMetrics metrics = camera.getMetrics();
    GraphicsContext g = bck.graphics2D();
    if (style.getStrokeMode() != StyleConstants.StrokeMode.NONE && style.getStrokeWidth().value > 0) {
        g.setStroke(ColorManager.getStrokeColor(style, 0));
        g.setFill(ColorManager.getStrokeColor(style, 0));
        g.setLineWidth(metrics.lengthToGu(style.getStrokeWidth()));
        int padx = (int) metrics.lengthToPx(style.getPadding(), 0);
        int pady = padx;
        if (style.getPadding().size() > 1)
            pady = (int) metrics.lengthToPx(style.getPadding(), 1);
        g.fillRect(padx, pady, (int) metrics.viewport[2] - padx * 2, (int) metrics.viewport[3] - pady * 2);
    }
}

Example 7 with GraphMetrics

use of org.graphstream.ui.view.util.GraphMetrics in project gs-ui-javafx by graphstream.

the class GraphBackgroundRenderer method fillGradient.

protected void fillGradient(GraphicsContext g, DefaultCamera2D camera) {
    GraphMetrics metrics = camera.getMetrics();
    if (style.getFillColors().size() < 2) {
        fillBackground(g, camera);
    } else {
        int w = (int) metrics.viewport[2];
        int h = (int) metrics.viewport[3];
        g.setStroke(GradientFactory.gradientInArea(0, 0, w, h, style));
        g.setFill(GradientFactory.gradientInArea(0, 0, w, h, style));
        g.fillRect(0, 0, w, h);
    }
