Detailed Description

Some helper functions to properly initialize a JPEG2000INFOHEADER2.

Process:

• RGB:
  Process = JP2K_PROCESS_R_53;

• Y & YUV:
  Process = JP2K_PROCESS_IR_97;

ColorSpaceID:

• RGB:
  ColorSpaceID = JP2K_sRGB_SPACE;

• Y:
  ColorSpaceID = JP2K_sLUM_SPACE;

• YUV:
  ColorSpaceID = JP2K_sYCC_SPACE;

SubSampling:

• 4:4:4 (no subsampling):
  HSubSampling = 1; VSubSampling = 1;

• 4:2:2 :
  HSubSampling = 2; VSubSampling = 1;

• 4:2:0 :
  HSubSampling = 2; VSubSampling = 2;
