I have figured out a solution. The steps are as the following, the core file
for the solution lies in OutputStream::writeImage function.
1. To write a image (e.g., *.jpg) inside a file, we need the WRITE_INLINE_FILE
mode, which is set by
Code:
osgDB::Options options;
options.setOptionString("WriteImageHint=IncludeFile");
osgDB::writeNodeFile(*node, "out.osgb", &options);
2. The image has to be first write to disk and a proper search path is needed.
A node visitor will do the image write correctly and the search path is set by
Code:
osgDB::setDataFilePathList(lists);
Cheers,
Han
