Write error: UseBitmap, pixel matrix is ​​very inaccurate

Question

I tried literally for hours, and I was not able to move this problem.

I have a UserControl, i.e. 800x369, and it just contains a path that forms a map of the world. I put this on the landscape page, then I turn it into a WriteableBitmap. Then I start the conversion to turn an array of 1d pixels into a 2d array of integers. Then, to test the conversion, I hook up a user click control command to use Point.X and Point.Y relative to the custom control in the newly created array. My logic is this:

wb = new WriteableBitmap(worldMap, new TranslateTransform());
wb.Invalidate();
intTest = wb.Pixels.To2DArray(wb.PixelWidth);

My conversion logic is this:

public static int[,] To2DArray(this int[] arr,int rowLength)
{
    int[,] output = new int[rowLength, arr.Length / rowLength];
    if (arr.Length % rowLength != 0) throw new IndexOutOfRangeException();
    for (int i = 0; i < arr.Length; i++)
    {
        output[i % rowLength, i / rowLength] = arr[i];
    }
return output;
}
