Created attachment 171070 [details] Snippet to reproduce If you use gc.drawImage() to draw a stretched image, this image is faded out near the left border (becomes transparent) on FF and IE. In the snippet I have a small test image, here 8x40 px and stretch it to a size of 200x100 pix. As result I see: IE8: Fading around borders FF3.6: Fading around borders Safari: No fading Opera: No fading Chrome: No fading
I can reproduce this problem only in FF, not IE. There it is a bug in the antialiasing of the canvas-element. We have no way to fix this as long as we use this technology for GC. Should you find a way for me to reproduce the bug in IE (perhaps its related to the image you use), feel free to reopen the bug.
Created attachment 173167 [details] image used in snippet The following code as part of a View produces sort of fading in IE. The fading gets even bigger, if the view is maximized. public void createPartControl(Composite parent) { parent.setLayout(new FillLayout()); final Canvas c = new Canvas(parent, SWT.NONE); c.addPaintListener(new PaintListener() { @Override public void paintControl(PaintEvent event) { GC gc = event.gc; gc.drawImage(Graphics.getImage("images/selected_bc.png", ListTestPart.class.getClassLoader()) , 0, 0, 19, 38, 0, 0, c.getBounds().width, c.getBounds().height); }}); }
If it still doesn't work for you, feel free to close it again. Thanks, Niels
This is very old issue which can't be reproduced with the latest, supported by RAP browsers.
