我嘗試全功能的桌面應用程序的一個轉換到Windows手機應用程序，我是成功地轉化大部分things..but一個功能不工作，由於一些語法error.anyone知道Windows Phone中的位圖操作：如何處理GetPixel，SetPixel，PixelFormat等？
替代GetPixel， FromArgb， SetPixel， MemoryStream的， 元帥， ImageLockMode， 的PixelFormat
的代碼是這個
private void tresh()
{
int hight = image1.Source.Height;
int width = image1.Source.Width;
BitmapImage img = new BitmapImage(image1.Source);
BitmapImage newImg = new BitmapImage(width, hight);
int threshold = 0;
for (int i = 0; i < hight; i++)
{
for (int j = 0; j < width; j++)
{
int grayScale = (int)((img.GetPixel(j, i).R * 0.3) + (img.GetPixel(j, i).G * 0.59) + (img.GetPixel(j, i).B * 0.11));
Color nc = Color.FromArgb(grayScale, grayScale, grayScale);
newImg.SetPixel(j, i, nc);
}
}
image1.Source = newImg;
MemoryStream ms = new MemoryStream();
newImg.Save(ms, ImageFormat.Bmp);
byte[] bmpBytes = ms.GetBuffer();
threshold = getOtsuNumber(bmpBytes);
byte[] newBytArr = new byte[bmpBytes.Length];
for (int i = 0; i < bmpBytes.Length; i++)
{
if ((0xFF & bmpBytes[i]) >= threshold)
{
newBytArr[i] = ((byte)255);
}
else
{
newBytArr[i] = ((byte)0);
}
}
BitmapImage oldBmp = newImg;
width = oldBmp.Width;
int height = oldBmp.Height;
BitmapData oldData = oldBmp.LockBits(
new Rectangle(0, 0, oldBmp.Width, oldBmp.Height),
ImageLockMode.WriteOnly,
oldBmp.PixelFormat);
int length = oldData.Stride * oldBmp.Height;
byte[] stream = new byte[length];
Marshal.Copy(oldData.Scan0, stream, 0, length);
oldBmp.UnlockBits(oldData);
BitmapImage bmp = new Bitmap(width, height, oldBmp.PixelFormat);
BitmapData bmpData = bmp.LockBits(
new Rectangle(0, 0, width, height),
ImageLockMode.WriteOnly,
bmp.PixelFormat);
for (int n = 0; n < length; n++)
{
if ((0xFF & stream[n]) >= 57)
{
Marshal.WriteByte(bmpData.Scan0, n, ((byte)255));
}
else
{
Marshal.WriteByte(bmpData.Scan0, n, ((byte)0));
}
}
bmp.UnlockBits(bmpData);
image1.Source = bmp;
}
