Re: [Ossim-submissions] ossimNitfImageHeader factoring

[Walt B. <Wal...@jp...>]

David,

Thanks. I'm running with the latest ossim again. Attached are some changed 
nitfImageBand files.

I moved setBandRepresentation from V2_1 to V2_0, since 
theBandRepresentation is declared in 2_0. I also added these to V2_0:

virtual void setBandRepresentation(const ossimString& rep);
virtual ossimString getBandSignificance()const;
virtual void setBandSignificance(const ossimString& rep);

However, I had to leave a setBandRepresentation stub in V2_1, forwarding to 
the V2_0 method, since the loader wasn't picking up the inherited method at 
run-time (this shouldn't be necessary):

void ossimNitfImageBandV2_1::setBandRepresentation(const ossimString& rep) {
  ossimNitfImageBandV2_0::setBandRepresentation(rep);
}

If you see something stupid I'm doing here, please let me know.

BTW,

support_data/ossimNitfFileHeaderV2_X.cpp:246 has
ossimNumericProperty* numericProperty = NULL;
but numericProperty isn't used.

support_data/ossimSpotDimapSupportData.cpp:1237 has
vector<ossimRefPtr<ossimXmlNode> >::iterator node;
but node isn't used.

Thanks,
Walt

[Ossim-submissions] New method in ossimNitfWriter allows saving registered tags

[Walt B. <Wal...@jp...>]

Garrett,

Here's the second set....

Are are the *.h and *.cpp for class ossimNitfWriter, enhanced by adding a 
new public method:

addRegisteredTag(ossimRefPtr<ossimNitfRegisteredTag> registeredTag);

that allows the following very easy creation of NITF from a file of raw 
pixels and its omd file:

ossimImageHandler * ih = ossimImageHandlerFactory::instance()->open( 
ossimFilename( inPath ) );
ossimNitfWriter nw( outPath, ih );
ossimNitfUse00aTag * use00aTag = new ossimNitfUse00aTag;
use00aTag->setAngleToNorth("42.0");
ossimRefPtr<ossimNitfRegisteredTag> registeredTag = use00aTag;
nw.addRegisteredTag(registeredTag);
nw.execute();
