title: Image to BGRA Format
body: <p>I have a image/bitmap (I can make it either) in c++ that I need to convert to BGRA format for ARToolkit. Is there any way to do this?</p>
  
  <p>What I really want to do is make a custom input for ARtoolkit which involves feeding in my own image (in BGRA format, which is required) to the high level tracking functions instead of the default webcam loader.</p>
  
  <p>Thanks,
  Christian Stewart</p>
