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

Example 1 with GraphMetrics

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

the class GraphBackgroundRenderer method fillImageTiled.

private void fillImageTiled(GraphicsContext g, DefaultCamera2D camera) {
    GraphMetrics metrics = camera.getMetrics();
    double px2gu = metrics.ratioPx2Gu;
    Image img = null;
    img = ImageCache.loadImage(style.getFillImage());
    if (img == null) {
        img = ImageCache.dummyImage();
    }
    // + ( padx * 2 )	// consider the padding ???
    double gw = (metrics.graphWidthGU() * px2gu);
    // + ( pady * 2 )	// probably not.
    double gh = (metrics.graphHeightGU() * px2gu);
    double x = (metrics.viewport[2] / 2) - (gw / 2);
    double y = metrics.viewport[3] - (metrics.viewport[3] / 2) - (gh / 2);
    g.setFill(new ImagePattern(img));
    g.fillRect(0, 0, metrics.viewport[2], metrics.viewport[3]);
}

Example 2 with GraphMetrics
