Issues Converting Resource File Images into Byte Arrays than into SFML Images

[StormWingDelta]

Not sure if it is the code I'm using or SFML but whatever the case something has imploded.  Managed to get it to a point that the only issue left is color not wanting to play nice and stay the same.  Worst case though is the image doesn't show or is turned into a line. 


Here's the current coding from the SFML images up above.

Image image = new Image((uint)TestImages.TestShip.Width,
                    (uint)TestImages.TestShip.Height,
                    GetRGBValues(new System.Drawing.Bitmap(TestImages.TestShip)));
                Image image2 = new Image((uint)TestImages.ClosedGridHall.Width,
                    (uint)TestImages.ClosedGridHall.Height,
                    GetRGBValues(new System.Drawing.Bitmap(TestImages.ClosedGridHall)));
                Image image3 = new Image((uint)TestImages.TestShip.Width,
                    (uint)TestImages.TestShip.Height,
                    MarshalImageToByteArray(new System.Drawing.Bitmap(TestImages.TestShip)));

                Sprite exsprite = new Sprite(new Texture(image));
                Sprite exsprite2 = new Sprite(new Texture(image2));
                Sprite exsprite3 = new Sprite(new Texture(image3));
 

Commented out the one that doesn't work for what I'm doing.  Now I'm down to 3 the commented out one doesn't work with images stored as resource files.

Here's an image of the several errors. >.>

Top two are fine but the image color is off.  The last one on the left is distorted to heck and back.  The one on the right is loaded from file normally.  I Have no idea where I'm messing up.

Do what you want with this... it only took me 10 minutes 

Yes the code is messy because I didn't bother to clean it up.

            RenderWindow wind = new RenderWindow(new VideoMode(500, 500), "Test");
            wind.SetVerticalSyncEnabled(true);
            Texture tx1 = new Texture("LBB.png");
            Sprite sp1 = new Sprite(tx1) { Scale = new Vector2f(.4f, .4f) };

hmm should be interesting.  Also working on a version of my own to see if I can get it working myself too.   I'll post my solution if it works along with yours so people won't be asking about how to do this in the future.   Or at least so we can show them how to do it without having to get a headache.

Here's My Solution.  Had to flip a few things for some odd reason but it works.

        private SFML.Graphics.Image ToSFMLImage(System.Drawing.Bitmap bmp)
        {
            SFML.Graphics.Color[,] sfmlcolorarray = new Color[bmp.Height, bmp.Width];
            SFML.Graphics.Image newimage = null;
            for (int x = 0; x < bmp.Width; x++)
            {
                for (int y = 0; y < bmp.Height; y++)
                {
                    System.Drawing.Color csharpcolor = bmp.GetPixel(x, y);
                    sfmlcolorarray[y,x] = new SFML.Graphics.Color(csharpcolor.R, csharpcolor.G, csharpcolor.B, csharpcolor.A);
                }
            }
            newimage = new SFML.Graphics.Image(sfmlcolorarray);
            return newimage;
        }

        private SFML.Graphics.Texture ToSFMLTexture(System.Drawing.Bitmap bmp)
        {
            return new Texture(ToSFMLImage(bmp));
        }
