Hi,
I am not sure, if the following is a browser feature or not:
If a use gc.drawImage() to draw a stretched image, this image is faded out near the left border.
Sample:
I have a small test image, here 7x34 px. And draw it up to a size of 200x100 pix using the following code:
public void createPartControl(Composite parent) {
parent.setLayout(new FillLayout());
final Canvas c = new Canvas(parent, SWT.NONE);
c.addPaintListener(new PaintListener() {
public void paintControl(PaintEvent event) {
GC gc = event.gc;
gc.drawImage(Graphics.getImage("images/test.png", TestPart.class.getClassLoader().class.getClassLoader()), 0, 0, 7, 34, 0, 0, 200, 100);
}});
}
As result I see:
IE8: Fading near left border
FF3.6: Fading near right and left border
Safari: No fading
Opera: No fading
What is this? And how can I turn it off for all browsers?
Thanks,
Niels

Nils,
as the behaviour is inconsistent among different browsers it looks like
a bug. Though I am not sure I anything can be done about it, feel free
to file a bugzilla.
