NITRO ENGRDA doesn't work

[sherrick01821]

I have been unable to add an ENGRDA TRE successfully with Nitro. It complains either the ENGLLB[0] doesn't exist which it does and the ENGDATA[0] label doesn't exist. I suspect that is why there is no test example code with nitro. If someone has a simple example of a successfull ENGRDA addition please post.

Perhaps you can post a minimal, self-contained, compileable example of what you are trying to do?

[sherrick01821]

nitf::TRE engrda("ENGRDA","ENGRDA");

float mydata = 100.f;

engrda.setField("RECNT",1);
engrda.setField("ENGLN[0]",6);
engrda.setField("ENGLBL[0]","mydata");
engrda.setField("ENGMTXC[0]",1);
engrda.setField("ENGMTXR[0]",1);
engrda.setField("ENGDTS[0]",4);
engrda.setField("ENGDATC[0]",1);
engrda.setField("ENGDATA[0]",mydata);

Sorry I wasn't clearer. Try reading http://sscce.org/

Minimise the work everyone else has to do to help you. Please provide a complete compilable sample that demonstrates the issue.

#include
#include <nitf/TRE.hpp>
#include <except/Exception.h>

int main()
{

#if 0
nitf::TRE tre( "PIXMTA" , "PIXMTA" );

tre.setField("NUMAIS", "001");

#if 1
nitf::TREFieldIterator it = tre.begin();
while( it != tre.end() )
{
nitf::Pair pair = *it;
std::cout << pair.first() << " " << pair.second() << std::endl;

 	++it;

}
#endif

tre.setField("AISDLVL[0]", 200, true);

#endif

nitf::TRE engrda("ENGRDA" , "ENGRDA" );

engrda.setField("RESRC","HSS");
engrda.setField("RECNT",1);

nitf::TREFieldIterator it = engrda.begin();
while( it != engrda.end() )
{
nitf::Pair pair = *it;
std::cout << pair.first() << std::endl;

 	++it;

}

try {
char val = 'A';
engrda.setField("ENGLN[0]",5);
engrda.setField("ENGMTXC[0]",1);
engrda.setField("ENGMTXR[0]",1);
engrda.setField("ENGTYP[0]","A");
engrda.setField("ENGDTS[0]",1);
engrda.setField("ENGDATC[0]",1);
engrda.setField("ENGDATA[0]",val);
}
catch( except::Exception & e )
{
std::cout << "Threw exception " << e.what() << std::endl;
}

}

This example throws an exception that ENGDATA[0] is not a recognixed field for this TRE

the fields printed in the iterator loop are
RESRC
RECNT
ENGLN[0]
ENGMTXC[0]
ENGMTXR[0]
ENGTYP[0]
ENGDTS[0]
ENGDATU[0]
ENGDATC[0]

Can someone run this and see if they get the same issue? Why isn't ENGDATA[0] not a valid field and how does one put a value in?

Then how do you set the actual engineering data? ENGDATA is a valid field according to the nga documentation  Sent from Yahoo Mail on Android On Wed, Aug 25, 2021 at 5:55 PM, J.

In the bugfix/ENGRDA branch:

TEST_CASE(basicIteration_ENGRDA)
{
    nitf::TRE engrda("ENGRDA", "ENGRDA");

    engrda.setField("RESRC", "HSS");
    engrda.setField("RECNT", 1, true /*forceUpdate*/);

    engrda.setField("ENGDTS[0]", 8); // size
    engrda.setField("ENGDATC[0]", 1); // count
    engrda.updateFields();
    engrda.setField("ENGDATA[0]", "ABC");
}

The TRE is ENGRD but the field I want to set is called ENGDATA this is an example I found online On Wednesday, August 25, 2021, 8:30:21 PM EDT, Steven Herrick ***@***.***> wrote: Then how do you set the actual engineering data?

Interesting, the test mod code you pointed to has the ENGDATA commentred out, probably because it doesn't work On Wednesday, August 25, 2021, 8:30:21 PM EDT, Steven Herrick ***@***.***> wrote: Then how do you set the actual engineering data?

I'll try it today, thanks On Thursday, August 26, 2021, 10:34:10 AM EDT, J.

Do you know how to put an array say on integrers in as ENGDATA? I knwo I would use ENGMTXC and ENGMTXR buit I 'm not sure uif I just put the array as the arg to ENGDATA[0] On Thursday, August 26, 2021, 10:34:10 AM EDT, J.
