Hi all:
I have added a Image in the figure in logic .And I want to change the
size of the Image when I change the size of DDFigure, but when changed the
DDFFigure's size ,the Image becomes distortion.How can I do to avoid it?
thanks
the programs as follows:
public class DDFFigure extends NodeFigure implements HandleBounds {
........
protected void paintFigure(Graphics g) {
Rectangle r = getBounds().getCopy();
g.translate(r.getLocation());
g.setBackgroundColor(LogicColorConstants.blue);
g.setForegroundColor(LogicColorConstants.connectorGreen);
g.fillRectangle(0, 0, r.width, r.height);
int right = r.width - 1;
g.drawLine(0, Y1, right, Y1);
g.drawLine(0, Y1, 0, Y2);
g.setForegroundColor(LogicColorConstants.connectorGreen);
g.drawLine(0, Y2, right, Y2);
g.drawLine(right, Y1, right, Y2);
g.setForegroundColor(LogicColorConstants.connectorGreen);
g.setBackgroundColor(LogicColorConstants.connectorGreen);
topConnector.translate(0, 5);
g.fillPolygon(rightConnector);
g.drawPolygon(rightConnector);
g.fillPolygon(leftConnector);
g.drawPolygon(leftConnector);
g.fillPolygon(topConnector);
g.drawPolygon(topConnector);
g.fillPolygon(downConnector);
g.drawPolygon(downConnector);
g.setFont(DISPLAY_FONT);
g.setForegroundColor(DISPLAY_TEXT);
g.drawText("DDF", 8, 6);
Image image = new Image(null, LogicEditor.class
.getResourceAsStream("icons/model/toponode16.gif"));
int x = getBounds().getCopy().width;
int y = getBounds().getCopy().height;
//when Rectangle's size changed ,the image becomes distortion,how
can I do ?
g.drawImage(image,0, 0, image.getBounds().width,
image.getBounds().height,
0, 0, x, y);
topConnector.translate(0, -5);
}

If you maintain the aspect ratio, it won't distort. Otherwise there's no
way to scale the image by different amounts in different directions and
still have it not distort, is there?

What do you mean by distorted? SWT only offers us one way to scale an
Image. The algorithm uses nearest-neighbor scaling I think, and not linear
interpolation a.k.a. "re-sampling" the image.
