The Planar Configuration attribute (0028,0006) is only used in DICOM colour images, and specifies how the pixel data are arranged.

• If the Value is 0, then they are grouped by location, e.g.
  RGBRGBRGBRGBRGB

• If the Value is 1, then they are grouped by sample, e.g.
  RRRRR……GGGGG…….BBBBB…..

In this latter case, they are still grouped by frame in a multi-frame image, so the order would be:

• Red for frame 1
• Green for frame 1
• Blue for frame 1
• Red for frame 2

etc…
