Re: [platform-swt-dev] shell region from image

[Veronika Irvine <Veronika_Irvine@xxxxxxxxxx>]

There is no method like 
        r.addData( new ImageLoader("c:/test.jpg").getData() );

Instead, you need to do something like:

Region region = new Region(display);
ImageData data = image.getImageData();
ImageData mask = data.getTransparencyMask();
Rectangle pixel = new Rectangle(0, 0, 1, 1);
for (int y = 0; y < mask.height; y++) {
        for (int x = 0; x < mask.width; x++) {
                if (mask.getPixel(x, y) != 0) {
                        pixel.x = data.x + x;
                        pixel.y = data.y + y;
                        region.add(pixel);
                }
        }
}

Subject
[platform-swt-dev] shell region from image






Is there currently a way of creating a region from an image found on the 
filesystem.  I would like to create a shell with curved edges and would 
rather use a pre-defined image than use a Rectangle and remove the edges 
via code.

I'm looking for something like:

Region r = new Region();
r.addData( new ImageLoader("c:/test.jpg").getData() );
shell.setRegion( r );

Thanks,
  Colin
