Rendering SVG Image in GEF [message #520170]

Hello,

I am trying to display a svg image in an edit part in my gef application. I am trying to get the figure like below

RenderInfo renderInfo = RenderedImageFactory.createInfo(20, 40, false, false, new RGB(255, 255, 255), new RGB(0, 0, 0));
figure = new ScalableImageFigure(RenderedImageFactory.getInstance("C:\\temp1\\test.svg ",renderInfo));

However the quality of the image being rendered is very bad. Is there any better way to have an svg image in my edit part with quality.

I would also like to say that the image quality is as expected when i export the image to another svg. I export as below

Rectangle rootFigureBounds = rootFigure.getBounds();
GraphicsSVG graphics = GraphicsSVG.getInstance(rootFigureBounds.getTranslated(rootF igureBounds.getLocation().negate()));

graphics.translate(rootFigureBounds.getLocation().negate());
rootFigure.paint(graphics);
OutputStream outputStream;
try {
outputStream = new FileOutputStream (saveLocation);
graphics.getSVGGraphics2D().stream(new BufferedWriter(new OutputStreamWriter(outputStream)));

} catch (Exception e) {
e.printStackTrace();
}

[The resultant svg image out of the above code is as expected though the svg contents in editor were distorted]
Could anyone please point me in the direction of displaying the svg image in gef .

Thanks in advance for help

Regards,
Bhat

Hi,

I have same question. Can we use SVG fimages in drawing the images(figures) for drawing the GEF Figures.

In some blogs, somebody has mentioned that GMF can use SVG Images for rendering via the ScalableImageFigure class.

But is it possible use SVG Image in GEF Figures (that used Draw2D) for rendering its figures.

If possible, give any hint or sample code.

Thanks in advance.
Deepak

Hello Deepak,

Below is a small snippet which i created that exports a Ifigure created from draw2d into an svg

public void exportToSVG(String saveLocation, IFigure rootFigure, IProgressMonitor monitor) {
SubProgressMonitor subProgressMonitor = new SubProgressMonitor(monitor, 10);
subProgressMonitor.setTaskName("Creating SVG image...");
Rectangle rootFigureBounds = rootFigure.getBounds();
GraphicsSVG graphics = GraphicsSVG.getInstance(rootFigureBounds.getTranslated(rootF igureBounds.getLocation().negate()));
SVGIDGenerator generator = new SVGIDGenerator();

subProgressMonitor.worked(2);
graphics.getSVGGraphics2D().getGeneratorContext().setIDGener ator(generator);
graphics.translate(rootFigureBounds.getLocation().negate());
rootFigure.paint(graphics);
OutputStream outputStream = null;
try {
outputStream = new FileOutputStream (saveLocation);
graphics.getSVGGraphics2D().stream(new BufferedWriter(new OutputStreamWriter(outputStream)));
subProgressMonitor.worked(4);
subProgressMonitor.done();
} catch (Exception e) {
e.printStackTrace();
}
subProgressMonitor.done();

}

Hope it helps.

Regards,
Bhat

Hi Bhat,

Thanks for your reply.

Right now we are using draw2d for rendering the figures in GEF Editor.
But my question is that can we use SVG Images for rendering our images on the GEF Editor.

Any ides or sample code would be helpful.

I guess in GMF you can render a svg image. So if you look at the way how gmf does it, you could use the same thing.

http://dev.eclipse.org/viewcvs/viewvc.cgi/org.eclipse.gmp/or g.eclipse.gmf.tooling/plugins/org.eclipse.gmf.runtime.lite.s vg/src/org/eclipse/gmf/runtime/lite/svg/SVGFigure.java?view= markup&root=Modeling_Project

Seems like there is no dependency over GMF. You can re-use this Figure as-it.
