AFAIK j2k.h and jp2.h header files are not installed on a standard
openjpeg installation. Is this intended ?
Here is the issue I am currently facing, in order to reject lossy
JP2/J2K stream in clinical trial environment I had to code the
following:
int reversible;
opj_j2k_t* j2k = NULL;
opj_jp2_t* jp2 = NULL;
switch(parameters.decod_format)
{
case J2K_CFMT:
j2k = (opj_j2k_t*)dinfo->j2k_handle;
assert( j2k );
reversible = j2k->cp->tcps->tccps->qmfbid;
break;
case JP2_CFMT:
jp2 = (opj_jp2_t*)dinfo->jp2_handle;
assert( jp2 );
reversible = jp2->j2k->cp->tcps->tccps->qmfbid;
break;
default:
gdcmErrorMacro( "Impossible happen" );
return false;
}
LossyFlag = !reversible;
Unfortunately I need to include j2k.h / jp2.h which is completely
non-standard on linux distribution.
What other people recommend for this situation:
- Extend openjpeg installation mechanism to install j2k.h / jp2.h
- Extend openjpeg.h API to return the reversible flag.
Thanks for suggestion
