如何将缓冲区读取器转换为位图

Question

 connection = (HttpURLConnection) new URL(params[0]).openConnection();
 connection.setRequestProperty("Cookie", mCookiesList.get(0) + ";" + mCookiesList.get(1));
 connection.connect();
 BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream()));

`

Answer 1

您可以使用javax.imageio.ImageIO类构造具有InputStream的BufferedImage：

BufferedImage bufferedImage = ImageIO.read(connection.getInputStream());

然后，如果您打算将磁盘写为位图：

int imageWithInPixels = 200;
int imageHeightInPixels = 200;
BufferedImage bitmapImage = new BufferedImage(imageWithInPixels , imageHeightInPixels , BufferedImage.TYPE_INT_RGB);
bitmapImage.getGraphics().drawImage(
    bufferedImage , 0, 0, imageWithInPixels , imageHeightInPixels , null);
ImageIO.write(bitmapImage , "BMP", new File("filename.bmp"));
