title: How to resize 8bpp bitmap image in c#?
body: <p>This is for duplication recognition.</p>
  
  <p>I can covert a image into 8bpp bitmap but since it's an indexed pixel format, I don't know how to resize it smaller. Is there anyway to do it without changing it to a higher pixel format (which will introduce more unwanted color)?</p>
  
  <p>Thanks</p>
