A method for forming boron oxide films formed using reactive sputtering. A first one of the image data samples is accessed and then a second one of the image data samples is accessed. The electronic computing device is further configured to add 610 text to the reply e-mail indicating the e-mail account adder forwarded the received e-mail to the e-mail account or to send 614 an auto-generated e-mail notification to the at least one participant of the e-mail thread indicating the e-mail account adder added the e-mail account to the e-mail thread as a participant. A comparison may be made with another build, so that the present invention may automatically execute selective tests on any types, and their dependencies, that have had a structural or behavioral modification since the last build. The encryption method includes encrypting portions within the document containing structural information with an asymmetric public key, encrypting portions within the document containing content information with a symmetric private key, and outputting the document, whereby a service provider provided with a public key is able to access and process only the structural information. Included in the highlighted portion are all focused portions of objects within the depth of field.
