HI,Everyone:
I have add a image on diagram,when i open the editor,the image of the
diagram can not display normally.(the results in attachment1.png)
when I use Marquee tool select the diagram or drag the child of diagram,the
image will display Irregularly.(the results in attachment2.png)

how can i make the image in editor display normally?

many thanks!!!

the code add the image in diagramEditpart in createFigure method as follows:

protected IFigure createFigure() {
Figure figure = new FreeformLayer()
{
protected void paintFigure(Graphics graphics) {
super.paintFigure(graphics);
if(getDiagram().getBackgroudImage()!=null) {
File file = new File(getDiagram().getBackgroudImage());
if (file.isFile()) {
if (BG_IMAGE != null) {
BG_IMAGE = null;
}
FileInputStream input = null;
try {
input = new FileInputStream(file);
BG_IMAGE = new Image(null, input);
graphics.drawImage(BG_IMAGE, 0, 0);
} catch (FileNotFoundException e) {
BG_IMAGE.dispose();
try {
input.close();
} catch (IOException e1) {
e1.printStackTrace();
}
e.printStackTrace();
}finally {
BG_IMAGE.dispose();
try {
input.close();
} catch (IOException e1) {
e1.printStackTrace();
}
}

}
}

}
};
figure.repaint();
figure.setLayoutManager(new FreeformLayout());
return figure;
}

Hi,

Although I couldn't look at the attached screen shots, I've tried to help
you out here by setting a background image for the logic diagram figure.
Below I'll provide a code snippet for the extended FreeFormLayer figure
(i.e. FreeFormLayerWithImageBGR figure). Essentially, this is the code
snippet you provided in your problem description with 2 differences:
1) Image is cached
2) Image is scaled to occupy the whole diagram.

Code snippet:

#######################################################
package org.eclipse.gef.examples.logicdesigner.figures;

import java.io.FileInputStream;

import org.eclipse.swt.graphics.Image;

import org.eclipse.ui.PlatformUI;

import org.eclipse.draw2d.FreeformLayer;
import org.eclipse.draw2d.Graphics;
import org.eclipse.draw2d.geometry.Rectangle;


public class FreeFormLayerWithImageBGR
extends FreeformLayer {

Image image;

public FreeFormLayerWithImageBGR(String path) {
super();
try {
setImage(new Image(PlatformUI.getWorkbench().getDisplay(),
new FileInputStream(path)));
} catch (Exception e) {
System.out.println(e);
setImage(null);
}

}

public Image getImage() {
return image;
}


public void setImage(Image image) {
this.image = image;
}

protected void paintFigure(Graphics graphics) {
if (getImage() != null) {
Rectangle targetRect = getBounds().getCopy();
org.eclipse.swt.graphics.Rectangle imgBox =
getImage().getBounds();
graphics.drawImage(getImage(), 0, 0, imgBox.width,
imgBox.height,
targetRect.x, targetRect.y, targetRect.width,
targetRect.height);
}
super.paintFigure(graphics);
}
}
################################################

To set it up for logic example:
in LogicDiagramEditPart#createFigure() instead of:
IFigure f = new FreeFormLayer()

put

IFigure = new FreeFormLayerWithImageBGR("<full path to the image file>");
(Note: don't try SVG images)

Please try this out, let me know if this helps.

Cheers,
Alex
