解析:android 如何從JPEG產生BufferedImage

如下所示：
複製代碼 代碼如下:private void readImage(String filename) throws FileNotFoundException, IOException {
FileInputStream fIn = new FileInputStream(filename);

//需要替換這邊的兩句：
JPEGImageDecoder jpeg_decode = JPEGCodec.createJPEGDecoder(fIn);
BufferedImage image = jpeg_decode.decodeAsBufferedImage();
width = image.getWidth();
height = image.getHeight();
int[] rgbdata = new int[width * height];
image.getRGB(0,0,width,height,rgbdata,0,width);
bytes = new byte[rgbdata.length];
doubles = new double[rgbdata.length];
for (int i = 0; i < bytes.length; i++) {
bytes[i] = (byte) (rgbdata[i] & 0xFF);
doubles[i] = (double)(rgbdata[i]);
}
}
