(

CJpegCommonStructs::opj_cparameters_t *

_pdParameters

)

[static]

Set encoding parameters to default values, that means:

• Lossless
• 1 tile
• Size of precinct : 2^15 x 2^15 (means 1 precinct)
• Size of code-block : 64 x 64
• Number of resolutions: 6
• No SOP marker in the codestream
• No EPH marker in the codestream
• No sub-sampling in x or y direction
• No mode switch activated
• Progression order: LRCP
• No index file
• No ROI upshifted
• No offset of the origin of the image
• No offset of the origin of the tiles
• Reversible DWT 5-3

Parameters:

_pdParameters
