处理8位灰度图像显示编码：

灰色编码

for(int i=0;i<256;i++)
{
  pColorTable[i].rgbBlue=i;
  pColorTable[i].rgbGreen=i;
  pColorTable[i].rgbRed=i;
  pColorTable[i].rgbReserved=0;
}

红色饱和度编码

for(int i=0;i<256;i++)
{

   pColorTable[i].rgbBlue=0;
   pColorTable[i].rgbGreen=0;
   pColorTable[i].rgbRed=i;
   pColorTable[i].rgbReserved=0;
}

绿色饱和度编码

for(int i=0;i<256;i++)
{

   pColorTable[i].rgbBlue=0;
   pColorTable[i].rgbGreen=i;
   pColorTable[i].rgbRed=0;
   pColorTable[i].rgbReserved=0;
}

蓝色饱和度编码

for(int i=0;i<256;i++)
{

   pColorTable[i].rgbBlue=i;
   pColorTable[i].rgbGreen=0;
   pColorTable[i].rgbRed=0;
   pColorTable[i].rgbReserved=0;
}

黄色饱和度编码

for(int i=0;i<256;i++)
{

   pColorTable[i].rgbBlue=0;
   pColorTable[i].rgbGreen=i;
   pColorTable[i].rgbRed=i;
   pColorTable[i].rgbReserved=0;
}

逆灰度编码

for(int i=0;i<256;i++)
{

   pColorTable[i].rgbBlue=255-i;
   pColorTable[i].rgbGreen=255-i;
   pColorTable[i].rgbRed=255-i;
   pColorTable[i].rgbReserved=0;
}

紫色饱和度编码

for(int i=0;i<256;i++)
{

   pColorTable[i].rgbBlue=i;
   pColorTable[i].rgbGreen=0;
   pColorTable[i].rgbRed=i;
   pColorTable[i].rgbReserved=0;
}

青色饱和度编码

for(int i=0;i<256;i++)
{

   pColorTable[i].rgbBlue=i;
   pColorTable[i].rgbGreen=i;
   pColorTable[i].rgbRed=0;
   pColorTable[i].rgbReserved=0;
}

热金属编码

for(int i=0;i<256;i++)
{

  if(i<64)
  {
   pColorTable[i].rgbBlue=4*i;
   pColorTable[i].rgbGreen=0;
   pColorTable[i].rgbRed=0;
  }
  else
   if(i<128)
   {
    pColorTable[i].rgbBlue=(i<96)? 255:225-8*(i-95);
    pColorTable[i].rgbGreen=0;
    pColorTable[i].rgbRed=4*(i-64);
   }
   else
    if(i<192)
    {
     pColorTable[i].rgbBlue=0;
     pColorTable[i].rgbGreen=4*(i-192);
     pColorTable[i].rgbRed=255;
    }
    else
    {
     pColorTable[i].rgbBlue=4*(i-192);
     pColorTable[i].rgbGreen=255;
     pColorTable[i].rgbRed=255;
    }

  pColorTable[i].rgbReserved=0;
}

彩虹编码

for(int i=0;i<256;i++)
{

   if(i<64)
   {
    pColorTable[i].rgbBlue=(i<32)? 8*i-1:255;
    pColorTable[i].rgbGreen=(i<32)? 0:8*(i-32);
    pColorTable[i].rgbRed=0;
   }
   else
    if(i<128)
    {
     pColorTable[i].rgbBlue=(i<96)?255-8*(i-64):0;
     pColorTable[i].rgbGreen=255;
     pColorTable[i].rgbRed=(i<96)?0:8*(i-96);
    }
    else
     if(i<192)
     {
      pColorTable[i].rgbBlue=0;
      pColorTable[i].rgbGreen=255-4*(i-128);
      pColorTable[i].rgbRed=255;
     }
     else
     {
      pColorTable[i].rgbBlue=0;
      pColorTable[i].rgbGreen=4*(i-192);
      pColorTable[i].rgbRed=255;
     }

pColorTable[i].rgbReserved=0;
}
