    Affects Versions: 2.5.0
         Environment: Windows8. Camera.cs
            Reporter: Dimitri Adamou

Hey there, noticed windows8 phone proj. was missing aspect ratio resize so added it in (Essentially copied iOS code)

---

        private struct ResizeDimension
        {
            public int width;
            public int height;

        }

        private ResizeDimension ResizeAspectRatio(int oWidth, int oHeight, int tWidth, int tHeight)
        {

            ResizeDimension tgt;


            float widthFactor = (float)tWidth / (float)oWidth;
            float heightFactor = (float)tHeight / (float)oHeight;
            float scaleFactor;

            if (widthFactor > heightFactor)
                scaleFactor = heightFactor;
            else
                scaleFactor = widthFactor;

            tgt.width = (int)Math.Min((float)oWidth * scaleFactor, tWidth);
            tgt.height= (int)Math.Min((float)oHeight * scaleFactor, tHeight);


            return tgt;
        }

---

and works via

ResizeDimension rd = ResizeAspectRatio(image.PixelWidth, image.PixelHeight, cameraOptions.TargetWidth, cameraOptions.TargetHeight);
            
image.SaveJpeg(stream, rd.width, rd.height, 0, cameraOptions.Quality);


Cheers,
Dim
