From manual page: http://www.php.net/function.px-set-blob-file#Parameters

set_blob_file() does not work for me when called in OO context, it does however work when called procedurally, there is no example on the site so I do not know if this is a documentation issue or not though I dont think it is. 

Test script:
---------------
<?php //not working
$fp = fopen("/home/httpd/vhosts/newjcs/VAL_MAIN.DB", "r");
$pxdoc = new paradox_db();
$pxdoc->set_blob_file('/data/httpd/vhosts/newjcs/VAL_MAIN.MB');
$pxdoc->close();
fclose($fp);

//works
$fp = fopen("/home/httpd/vhosts/newjcs/VAL_MAIN.DB", "r");
px_open_fp($pxdoc, $fp);
px_set_blob_file($pxdoc,'/home/httpd/vhosts/newjcs/VAL_MAIN.MB');
px_close($pxdoc);
px_delete($pxdoc);
fclose($fp);	

Expected result:
----------------
nothing, e.g. no errors or warnings using either methodology

Actual result:
--------------
in the OO script I receive the error

Fatal error: paradox_db::set_blob_file(): Paradox database has not been opened or created when setting the blob file. in /data/httpd/vhosts/centaur/httpdocs/val/index.php on line 4 

note that on my system /home/httpd is a symlink to /data/httpd

the second non-OO call works as expected with no errors and I am able to pull images from the blob
