JavaCV/OpenCV: cvLoadImage not working

java, javacv

Solution

A walk around that i find for you is to load the image by ImageIO and passe it later to `IplImage`

e.g.:

 BufferedImage img =  ImageIO.read(new File("C:\\img.jpg") );
 IplImage origImg = IplImage.createFrom(img);

Problem

I installed the JavaCV/OpenCV libraries, and I'm having a problem with the basic example code. According to several examples that I have looked at, this code should load an image: ``` IplImage image = cvLoadImage("C:\\img.jpg"); ``` But, when I run that I get a "cannot find symbol" error. Since this is my first time using it, I'm not sure if I messed the install up or not. According to the newest JavaCV readme, I do have the correct version of OpenCV. I also have all the JavaCV jar files imported. As far as I can tell, I also have all the paths set correctly too. Anyone know what the problem is? Edit: Full code: ``` import com.googlecode.javacv.CanvasFrame; import com.googlecode.javacv.cpp.opencv_core.IplImage; import java.io.File; public class demo { public static void main(String[] args) { IplImage image = cvLoadImage("C:\\img.jpg"); final CanvasFrame canvas = new CanvasFrame("Demo"); canvas.showImage(image); canvas.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE); } } ``` Error when I try to run it: Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: cvLoadImage at javacv.demo.main(demo.java:17) Java Result: 1 Seems like it is claiming cvLoadImage doesn't take a string as an argument.
