Examples of org.eclipse.swt.graphics.Transform.translate()

org.eclipse.swt.graphics.Transform.translate()
Modifies the receiver so that it represents a transformation that is equivalent to its previous transformation translated by (offsetX, offsetY). @param offsetX the distance to translate in the X direction @param offsetY the distance to translate in the Y direction @exception SWTException
- ERROR_GRAPHIC_DISPOSED - if the receiver has been disposed

    transform.translate((int) movClubX, (int) movClubY);
    transform.scale(scaleWidth, scaleWidth);


    // rotate on center of image
    Rectangle rect = ace_club.getBounds();
    transform.translate(rect.width / 2, rect.height / 2);
    transform.rotate(rotationAngle);
    transform.translate(-rect.width / 2, -rect.height / 2);
