Detailed Description

For U_PMF_BITMAP PxFormat field EMF+ manual 2.1.1.25, Microsoft name: PixelFormat Enumeration (U_PF_*)

  Bitmap for this 32 bit value is:
  0-9 ignored
  10  Set: 32 bit ARGB; Clear: !32 bit ARGB
  11  Set: 16 bits/channel; Clear: !16 bits
  12  Set: colors premultiplied by alpha; Clear: !premultiplied
  13  Set: has Alpha; Clear: !has Alpha
  14  Set: Windows GDI supports; Clear: !Windows GDI supports
  15  Set: uses LUT; Clear  !uses LUT
  16-23   = total number of BITS per pixel
  24-31   = pixel format enumeration index (0->15)
