问题描述

我试图从URL GIF图像加载到java.util.image.Raster这样我就可以操纵它。装载和DECOM pressing图像我能找到的唯一方法是Toolkit.getImage，它返回一个java.awt.Image中。我需要把它转换成一个光栅这样我就可以使用它。建议？

I'm trying to load a gif image from a url into a java.util.image.Raster so I can manipulate it. The only method for loading and decompressing an image I could find was Toolkit.getImage, which returns a java.awt.Image. I need to turn that into a Raster so I can work with it. Suggestions?

推荐答案

加载图像到一个缓冲图像，然后从中获取数据

Load your Image into a Buffered Image and then get the data from it

BufferedImage img = null;
try {
   img = ImageIO.read(new File ("c:/imageFile.gif"));
} catch(Exception e) {}

Raster R=img.getData();
