我正在尝试获取图像的宽度和高度,ImageView变量是 iv 。但似乎我总是低于错误。
java.lang.UnsatisfiedLinkError: No implementation found for long org.opencv.core.Mat.n_Mat(int, int, int) (tried Java_org_opencv_core_Mat_n_1Mat and Java_org_opencv_core_Mat_n_1Mat__III)

我的代码
public boolean onTouch(View v, MotionEvent event)
{
Bitmap bm =((BitmapDrawable)iv.getDrawable()).getBitmap();
int w = iv.getWidth();
int h = iv.getHeight();
mRgba = new Mat(w,h,CvType.CV_8UC4); <---- the error of line being described
int cols = mRgba.cols();
int rows = mRgba.rows();
int x = (int)event.getX();
int y = (int)event.getY();
}
