SWT Image 和ImageData的相互转换

ImageData 转 Image 

//arcPiclocate图片绝对路径
ImageData data= new ImageData(arcPiclocate);
Image image1 = new Image(null, data);
//或者 Display display = Display.getCurrent(); Image image1 = new Image(display , data);

Image 转 ImageData

使用getImageData()方法获取

Image image1 = new Image(null, data);
ImageData imageData = image1.getImageData();
