GeoPDF

    I tried to use this lib to generate a GeoPDF, but i don't know how to call 'AddLGIDictToPage'. There is not too much infomation about this function also others. So I don't know how to pass the parameter. Hope there is an example or some hints for me. 
 Thanks!

	Hi! I think your problem is the structure of the needed string... The AddLGIDictToPage depends on the OGC 08-139r2 specifications. You can read all about this specs here: http://www.opengeospatial.org/standards/bp ...in this document: "GeoPDF Encoding Best Practice Version 2.2" http://portal.opengeospatial.org/files/?artifact_id=33332 Cheers and welcome here, Ingo

	Hi Indo Thanks for you reply, I really appreciate it. I have read the specifications, and I got someting. I'm going to pass a whole PDF-Dictionray-Formatted string to the function offered. Hope it works. Best Regards! Mingoal

	Did you have any success with that? I'm trying to do the same, and I'm not even sure where to start. I have an idea of the format just by opening a GeoPDF in a text editor, but I can't get even GetPageLGIDictContent or GetPageLGIDictCount to work, so I don't know how I'm going to use AddLGIDictToPage.

	Hi jvonbokel I succeed in outputing a GeoPDF, below are the formatted-LGIDictContent , what you need to do is passing the whole text as a string to AddLGIDictToPage function. << /Type /LGIDict /Version (2.1) /CTM [ (3524.5004673001) (0.0000000000) (0.0000000000) (3524.5004673001) (-2493370.4940219196) (-1538087.6795059151) ] /Projection << /Type /Projection /ProjectionType (AC) /StandardParallelOne (20.00000) /StandardParallelTwo (60.00000) /FalseNorthing (0.00000) /Datum (NAR) /OriginLatitude (40.00000) /CentralMeridian (-96.00000) /FalseEasting (0.00000) >> /Display << /Type /Projection /ProjectionType (AC) /StandardParallelOne (20.00000) /StandardParallelTwo (60.00000) /FalseNorthing (0.00000) /OriginLatitude (40.00000) /CentralMeridian (-96.00000) /Units (M) /FalseEasting (0.00000) /Datum (NAR) >> /Description (Southwestern United States) /Registration [[ (53.5103998492) (124.5528002880) (-2304773.0647479948) (-1099101.2766873206) ] [ (725.0183996828) (560.4984001800) (61957.1944612906) (437389.1938494640) ]] /Neatline [ (53.5103998492) (124.5528002880) (53.5103998492) (560.4984001800) (725.0183996828) (560.4984001800) (725.0183996828)(124.5528002880) ] >> The LGIDict format is specified by <<GeoPDF Encoding Best Practice Version 2.2>> ,you can find it at http://www.opengeospatial.org/standards/bp. I also used GetPageLGIDictContent and GetPageLGIDictCount, they all work correctly, maybe you pdf file is not a correct GeoPDF file. Hope this may help you. Mingoal
