本文整理了Java中android.media.Image.getHeight()方法的一些代码示例，展示了Image.getHeight()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Image.getHeight()方法的具体详情如下：
包路径：android.media.Image
类名称：Image
方法名：getHeight

Image.getHeight介绍

[英]The height of the image in pixels. For formats where some color channels are subsampled, this is the height of the largest-resolution plane.
[中]图像的高度（以像素为单位）。对于某些颜色通道被二次采样的格式，这是最大分辨率平面的高度。

/**
 * Process image data as desired.
 */
@SuppressLint("NewApi")
private void processScreenImage(Image image) {
  if(!isPushing && !isRecording &&!isRTSPPublisherRunning)
  {
    return;
  }
  final Image.Plane[] planes = image.getPlanes();
  width_ = image.getWidth();
  height_ = image.getHeight();
  row_stride_ = planes[0].getRowStride();
  ByteBuffer buf = deepCopy(planes[0].getBuffer());
  synchronized(this)
  {
    data_list.add(buf);
  }
}

 * <p>
 * The crop rectangle specifies the region of valid pixels in the image,
 * using coordinates in the largest-resolution plane.
 */

  if (mCropRect == null) {
    return new Rect(0, 0, getWidth(), getHeight());
  } else {
    return new Rect(mCropRect); // return a copy
  }
}
