Problem creating image from a file in a bundle [message #327745]

Hi there,

in my plugin I try to create an image using a file in a separate
directory of my plugin. I use the code below to do this. But when doing
so, the image has a width and height of -1. Does anyone have a hint to
resolve this problem?

Image img =
ImageDescriptor.createFromURL(FileLocator.find(Activator.get Default().getBundle(),
new Path("data/EclipseBannerPic.jpg"),
null)).createImage(parent.getDisplay());

Thanks in advance

Jan

Jan,

Have you inspected the URL that comes back? What does it look like?
Does openStream on the URL return a stream without throwing an
exception? The "data" folder is at the root of your plugin? Usually
people use an "icons" folder. You've specified it in your
build.properties so it's included in the final jarred plugin when you
export?

also, most of the logic is already written for you in
org.eclipse.ui.plugin.AbstractUIPlugin.imageDescriptorFromPl ugin(String,
String)
