raster image list
raster image list
howdy,
i'm trying to take a list of raster images for the drawing.
could somebody explain me how i can get a raster image dictionary object?
any examples, parts of code, or links will be helpful.
thanks
here it is:
oddbdatabaseptr pdb;
<put database loading code here>
oddbdictionaryptr pimagedict;
oddbobjectid imagedictid = oddbrasterimagedef::imagedictionary( pdb );
if( !imagedictid.isnull() )
pimagedict = imagedictid.safeopenobject( oddb::kforread );
if( pimagedict.get() )
{
<...dictionary ready for reading...>
}
-------------

thanks you, marco.
i didn't call pimagedict.get(). now it's working fine.
thanks again.

sorry, i'm new here. could you tell how to read dictionary to get raster file path info? thanks.

if you want to get all raster images:
code:
oddbobjectid imagedictid = oddbrasterimagedef::imagedictionary( pdb );
if( !imagedictid.isnull() )
{
oddbdictionaryptr pimagedict = imagedictid.safeopenobject( oddb::kforread );
oddbdictionaryiteratorptr piter = pimagedict->newiterator();
while (!piter->done())
{
odstring strimagename = piter->name();
oddbrasterimagedefptr pimagedef = piter->getobject();
odstring strfilename = pimagedef->sourcefilename();
piter->step();
}
}

thank you very much, sergey.
one thing to be corrected. it should be piter->next() instead of piter->step() for oddbdictionaryiteratorptr. am i right?
thanks again.

odstring strfilename = pimagedef->sourcefilename();
piter->step();
}
}
please ignore this message. my mistake. but i cannot delete it
sorry to bother again.
i test the code with attached dwg file. i got "strimagename"s for the two raster files, but "strfilename"s are empty string for both of them. could you please tell me why?
thanks.
