Abstract
A method is provided by this invention wherein information needed for indexing or routing of facsimile images transmitted by standard facsimile means using CCITT protocols can be carried in the image in a form which does not interfere with conventional facsimile operation. This indexing information is carried by a pseudo bar code imbedded in the first line or lines of the image. The bar code is machine generated from operator input via a keyboard, and as such is at maximum resolution, without skew, and without scanner sampling errors. The use of multiple lines provides a bar code pattern which can be read by normal bar code reading means. This invention also includes means for extraction of the pseudo bar code from the facsimile image so that its existence is totally transparent to the users.
