Hi,
is it possible to align a label along a connection so it will stay aligned
in this way even when connection is drawed in the vertical direction?
Thanks in advance.

Ilja,
You can use the following snippet to get bitmap data for rotation.
label would be the Draw2D label figure you wish to rotate, width and
height correspond to the label width and height.
Image = new Image(display, width, height);
GC gc = new GC(image);
SWTGraphics graphics = new SWTGraphics(gc);
label.paint(graphics);
graphics.dispose();
gc.dispose();
image.getImageData() will return an ImageData object whose data field
would be the bitmap data. This data will vary according to your screen
depth - you could get an 8(not sure), 16, 24 or 32 bit bitmap.
Hope this helps,
Brian.
