Maya C++ plugin access to imageFile loaded on the current imagePlane - c++

Question

I am writing a Maya C++ plugin that needs to get access to the imageFile that is loaded in the current imagePlane. I've got the plugin written, and I am able to iterate successfully through the imagePlanes, but I don't know how to get the imageFile that is loaded on the imagePlane. I have written a plugin that has a callback for the scene being loaded, and I'm that successfully iterateing through the imagePlanes, but how do I proceed from there to get the filename of the image loaded into the imagePlane? Here's a portion of my code for the sceneLoaded callback:
void MayaExtractCalDataPlugin::sceneLoaded( void* clientData )
{
// Store the pointer to the current class
MayaExtractCalDataPlugin* crntPlugin = (MayaExtractCalDataPlugin*)clientData;
// We only enter the callback when isReadingFile() is false, as this indicates that all
// loading is complete. otherwise we would enter a whole series of callbacks when loading a scene
// with lots of references in.
if( !MFileIO::isReadingFile() )
{
// Traverse the scene and find image planes
// First we need to create an iterator to go through all image planes
MItDependencyNodes it(MFn::kImagePlane);
//iterate through all image planes
while(!it.isDone())
{
// Get the imagePlane object
MStatus status;
MObject object = it.thisNode(&status);
...
}
}
}
But, now that I have the MObject and I know its an imagePlane, I don't know how to get to the imageFile that is loaded into it. Thanks in advance for any help you can offer!

Answer 1

I figured it out! I just needed to add the following statements after the above code, and I can access all the imagePlane methods and attributes:
// attach a dependency node to the file node
MFnDependencyNode fn(object);
// get the attribute for the imageName path
MPlug imagePath = fn.findPlug("imageName");
