Try something like this:
you have so full control on what is happening:
/* with <file> someting like "/com/<mycompany>/images/mygig.gif " present
in your class path*/
URL imageURL = getClass().getResource(file);
TextureLoader tex = new TextureLoader(imageURL, "RGBA", <my
component>);
Appearance look = new Appearance();
/* the next 3 lines only to preserve the transparent background of my
gif */
TransparencyAttributes transp = new TransparencyAttributes();
transp.setTransparencyMode(TransparencyAttributes.BLENDED);
look.setTransparencyAttributes(transp);
if (tex != null) {
Texture t = tex.getTexture();
if (t != null) {
t.setBoundaryModeS(t.CLAMP);
t.setBoundaryModeT(t.CLAMP);
t.setBoundaryColor(0f, 0f, 0f, 0f);
look.setTexture(t);
}
