Hi Pat,

Take a look at man pfdConverterMode_pfb. You can turn on the
 PFPFB_SAVE_TEXTURE_IMAGE mode in order to include
actual texel data in your outputted pfb file.

For a quick test, I added the following 4 lines of code to texture.C
in /usr/share/Performer/src/pguide/libpf/C++ :

At the top of the file, with the other includes:

#include <Performer/pfdb/pfpfb.h>
#include <Performer/pfdu.h> ,

And, just after root->addChild(dcs2) :

pfdConverterMode( "pfb", PFPFB_SAVE_TEXTURE_IMAGE, PF_ON );
pfdStoreFile( root, "foo.pfb" );

This generates a large pfb file which seems to contain image data, as
required.

Hope this helps,
Paolo
