I get the image reversed in C#

Answer 1

Hey it looks like the two images you posted are not related in any way (besides have a similar pattern of obfuscation). Did you post the wrong files?

With regard to the issue you are seeing, I would guess you are seeing a problem with the origin of the x-y axis. Normal images and graphics APIs use a slightly weird axis where you count "down" the y axis, that is to say, the point(0, 0) is at the top left of the screen and as you increment y, you go down the screen. Therefore it seems reasonable to assume that you have made a mistake in the conversion or that the two images are using a different y axis scheme.

Answer 2

   bmp.RotateFlip(RotateFlipType.Rotate180FlipX);

Fixed the problem :)

Answer 3

Why not replace all that unsafe stuff with :

private static Bitmap ConvertFromBytes(Byte[] imagebytes)
{
   return new Bitmap(new MemoryStream(imagebytes));
}
