Read grayscale bitmap into array

[Simon666]

Hello,

I need to read in an 8 bit grayscale bmp and I want the value of its pixels stored in an array (can do that myself). I can't seem to get the value between 0 and 255, I always get zero with the code below. What's wrong?

 HANDLE hBitmap;  //Holds the Handle of the Bitmap once it is loaded.
 HDC hDC;  //Our temporary Device Context, which will be used to hold our Bitmap later on.

 hDC = CreateCompatibleDC(NULL);  //Create's a compatible Device Context(DC) and stores its value in 'hDC'.

 hBitmap = LoadImage(0,"E:\\Test.bmp",IMAGE_BITMAP,0,0,LR_LOADFROMFILE); //This loads our Image into memory and stores the handle in the variable "hBitmap". You may change the Directory from this API call to one containing your Image.

 //Get info about the bitmap
 
 BITMAP Bitmap;
 SIZE ImageSize;

 //Get info about the bitmap
 GetObject(hBitmap, sizeof(Bitmap), &Bitmap);
 ImageSize.cx=Bitmap.bmWidth;
 ImageSize.cy=Bitmap.bmHeight;

 SelectObject(hDC,hBitmap); //Puts our loaded Image into our temporary Device Context.

 for(int x=0;x<ImageSize.cx;++x)
 for(int y=0;y<ImageSize.cy;++y)
 {
  COLORREF color=GetPixel(hDC,x,y);

  // Problem here : color is always zero, I want the correct value and put it in an array
 }

 // Clean up

 DeleteDC(hDC);
