Hi,
I'm having some issues with the ScalableImageFigure. I'm trying to
render SVG images, and it all went well until I used
setMaintainAspectRatio(false), because the user should be allowed to
change the ratio.
The images get still rendered, but they don't fill the Figure. Instead
they are drawn way too small in the upper left corner of the figure.
When I use pixel based images (like png), it all works well, but no
matter what I'm trying, I can't make it work with SVG.
When I resize the figure, the images's aspect ratio and size changes
accordingly, so it all seems to be correct, except for the size of the
RenderedImage.
I couldn't find any bugs related to this behaviour and don't really
understand what I'm doing wrong here. Any kind of information would be
welcome.
This is how I create the Figure:
public class NodeFigure
extends
org.eclipse.gmf.runtime.draw2d.ui.render.figures.ScalableIma geFigure
{
/**
* @generated NOT
*/
public NodeFigure(String path)
{
super(RenderedImageFactory.getInstance(FileLocator.find(ItLa ndscapeDiagramEditorPlugin.getInstance().getBundle(),
new Path(path), null)), true, true, true);
this.setMaintainAspectRatio(false);
createContents();
}
The first attached image shows the result of adding a figure with
setMaintainAspectRatio(true), the second with false. Both figures have
the same (default) size.
Best regards,
Johannes
PS: I'm running GMF 3.2.2

Are your svg images smaller than your figure default size? If the figure
default size for example is 40x20 and your svg is ony 10x5 than you need
to change the
RenderedImageFactory.getInstance(<ImagePath>, true, true, true);
^^^^
to
RenderedImageFactory.getInstance(<ImagePath>, false, true, true);
^^^^^
This boolean is the "useDefaultImageSize" flag, if it is true, the size
of the figure doesn't matter, the svg will be rendered with its default
size. So if your svf is smaller than the default size of the figure it
results in this small image.

Hi Jens,
I created them with Inkscape and the SVGs are fine. No additional border
or anything. There should be no problem.
Best regards,
Johannes
