D3DAlwaysValidate(_Device->GetRenderTargetData(_Surface, _SurfacePlain), "GetRenderTargetData");
D3DLOCKED_RECT LockedRect;
D3DAlwaysValidate(_SurfacePlain->LockRect(&LockedRect, NULL, 0), "LockRect");

RGBColor *SurfData = (RGBColor*)LockedRect.pBits;
for(UINT y = 0; y < _Height; y++)
{
//memcpy(B[_Height - 1 - y], &SurfData[y * LockedRect.Pitch / 4], _Width * 4);
memcpy(B[y], &SurfData[y * LockedRect.Pitch / 4], _Width * 4);
}
_SurfacePlain->UnlockRect();

void D3D9Texture::ReadData(Bitmap &Bmp)
{
PersistentAssert(_Width != 0 && _Height != 0 && _Format == D3DFMT_A8R8G8B8 && _RenderTarget, "ReadData called on invalid surface");

Width = WindowCoord.right - WindowCoord.left;
Height = WindowCoord.bottom - WindowCoord.top; //get the Width/Height
B.Allocate(Width, Height); //allocate space
for(i=0; i<Height; i++)
{
for(i2=0; i2<Width; i2++)
{
B[Height-i-1][i2] = Bmp[i][i2]; //load the current screen into B
}
}
