PANDA_TRAVERSEOBJECTS(3)PANDA_TRAVERSEOBJECTS(3)NAMEpanda_traverseobjects - traverse the PDF object tree and perform an
operation
SYNOPSIS
#include<panda/constants.h>
#include<panda/functions.h>
void panda_traverseobjects (panda_pdf * output, panda_object * startObject, int direction, traverseFunct function);
DESCRIPTION
<command>PANDA INTERNAL</command>. This function traverses the object
tree created by <command>panda_addchild</command>() and repeatedly
calls the function defined as a callback. The traversal has a direction
as defined by: panda_up (bottom up) or panda_down (top down). This call
is commonly used by <command>panda_close</command> to call <com‐
mand>panda_writeobject</command>() and <command>panda_freeobject</com‐
mand>(). API users might also find it useful, although I wouldn't know
why.
RETURNS
None
EXAMPLE
#include<panda/constants.h>
#include<panda/functions.h>
panda_pdf *document;
panda_init();
document = panda_open("filename.pdf", "w");
... create a whole bunch of objects and add them to the tree ...
panda_traverseobjects(document, document->catalog, panda_down, panda_writeobject);
