Revision history [back]

This loads just fine:

    private Mat m = Imgcodecs.imread("C:/Users/Link/workspace/G3DExperiment/src/imgres/stone.png");

But for some reason I can't load it into an array:

public void draw(Mat mat, int x, int y) {
    int rows = mat.rows(), cols = mat.cols(), type = CvType.channels(mat.type());
    int[] bgr = new int[rows*cols*type];
    mat.get(0, 0, bgr);
    canvas.setRGB(x, y, cols, rows, bgr, 0, width);
}

The full stacktrace reads:

canvas is a BufferedImage of type TYPE_3BYTE_BGR and this method MatrixCanvas#draw(Mat, int, int) is used to draw a Mat directly onto the screen by covering the screen in a BufferedImage and setting the pixels on the image.
