I would do the normal stuff to resize the file:

$path = 'uploads/tx_myext/';

$info = $this->cObj->getImgResource($path . $filename, array('maxW' => 400);

$info[3] now contains the location and filename of the resized image.

@unlink($path . $filename);
@rename($info[3], $path . $filename);
@unlink($info[3]);

I left out the normal checks to see that the file manipulation functions 
did not fail. Also make sure that the $filename does not include a path!

Because this is internal file manipulation of the extension I don't 
think that t3lib_extFileFunctions::func_move() is relevant here; there 
is no need to do normal checks for permissions, etc. of a BE user. 
Please let me know if other think that I am completely wrong here...
