TColor警告提示问题，请帮忙！
下面是代码：

C/C++ code

void __fastcall TForm1::BitBtn2Click(TObject *Sender)  //最大值法灰度化{float red, green, blue, max;TColor color;width = Image1 -> Picture -> Width;height = Image1 -> Picture -> Height;bitmap = new Graphics::TBitmap();bitmap -> Width = width;bitmap -> Height = height;for(i = 0; i < width-1; i++)  for(j = 0; j < height-1; j++)    {    color = Image1 -> Canvas -> Pixels[i][j];    red = rgb[i][j].r_color = GetRValue(color);    green = rgb[i][j].g_color = GetGValue(color);    blue = rgb[i][j].b_color = GetBValue(color);    max = red > green ? red : green > blue ? green : blue;    bitmap -> Canvas -> Pixels[i][j] =RGB(max, max, max);    }  Image2 -> Picture -> Bitmap -> Assign(bitmap);}

run后会有如下提示，但是能够实现灰度化。这个warning如何debug掉？谢谢

[解决办法]
unsigned long给TColor赋值前加个强制类型转换 (TColor).
[解决办法]
是的，强制转换成TColor类型再赋值就行了。
