Load user image at runtime [message #1112319] Thu, 19 September 2013 12:30 Go to next message

Hi,

I have a Graphiti diagram representing scientific functions as rectangle. Each function has a Latex documentation. The user can change the documentation with a dialog box. When the dialog is closed, a "png" image is generated from the Latex entry. Is it possible to display this image into the rectangle representing the function ?

I try to use the ImageProvider but images have to be packaged with the plugin and the ImageProvider looks for images only in the plugin path. In my case, images are generated at runtime, during the use of my graphiti editor. I can build an swt image but not a Graphiti one. Any Idea ?

Thanks for your help.

Benoit,

I haven't tried that, but IAbstractImageProvider has a method
addImageFilePath that you can access from your own subclass. It should also
be possible to add images at runtime (but not to remove them again).

Thanks for your help.
I have tried this method but the path must be relative to the plugin.
It seems that you can't load an image from the runtime project home (the project used by the user of the plugin).

Yes, you can. Please see https://bugs.eclipse.org/bugs/show_bug.cgi?id=366452#c8 for an example.

I'm trying to achieve the same thing but i'm not getting it to work, even with the solution Felix Velasco proposed.

I've added the following method to my subclass that extends AbstractImageProvider: 
	public void addImage(String imageId, String imageFilePath){
		super.addImageFilePath(imageId, imageFilePath);
	}


I use the following code to get the Image from the runtime project and to make it available for the ImageProvider: 

IResource res = ResourcesPlugin.getWorkspace().getRoot().findMember("/test/src/channelTypes/sync/images/decorator-target.png");
imageProvider.addImage("reo.editor.test", res.getLocationURI().toString());


The ResourcesPlugin does seem to find the image, but unfortunately, i'm getting the following error when I start the project.
