The import org.opencv.imgcodecs.Imgcodecs cannot be resolved

Question

I installed OpenCV (opencv-3.0.0-alpha) and it works properly but I can't use that import:

import org.opencv.core.*;
import org.opencv.imgcodecs.Imgcodecs;

public class Main {

    public static void main(String[] args) {

//      System.loadLibrary("opencv_java244");
//      Mat m = Highgui.imread("C:/Users/raj/Desktop/sa1.png",
//              Highgui.CV_LOAD_IMAGE_COLOR);
//      new LoadImage("C:/Users/raj/Desktop/dst1.jpg", m);
    }
}

I get this error

The import org.opencv.imgcodecs.Imgcodecs cannot be resolved

How can I solve this?

@SagorAhmed and you are not suspicious that the jar is a major release behind to the installation you claim you have? Also which native-library are you using the x64 or x86 one? — Gildraths

@SagorAhmed You say you use OpenCV 3.0.0 but your jar is OpenCV 2.4.1. The reason this is important is because they changed the functionality of Highgui (not used in OpenCV 3.0.0 anymore) — Gildraths

And while you're installing new stuff, please install OpenCV 3.1. Version 3.0 alpha is, well, an alpha.... Use a stable release — Miki

OpenCV 3.0.0 is using the import:

import org.opencv.imgcodecs.Imgcodecs;

However the library you are using (OpenCV 2.4.1) is using different import for the same functionalites:

import org.opencv.highgui.Highgui;

https://fossies.org/diffs/opencv/2.4.11_vs_3.0.0-rc1/modules/java/android_test/src/org/opencv/test/highgui/HighguiTest.java-diff.html

Basically you are trying to import something that doesn't exist in the version you are using.

Now you can either use Highgui or get the jar for OpenCV 3.1.x
