Generating landscape and portrait oriented tags
First Claim
Patent Images
1. A method for generating landscape or portrait oriented tags embedded with error correctable data, comprising the steps of:
- using an encoder in the printing of a tag having a data area comprising data dots and a locator component comprising constant dots;
using the tag encoder to obtain, from a stored tag format structure, required data in row-wise or column-wise directions, for both landscape and portrait orientations of the tag;
the tag format structure being a dot based data package template containing a plurality of entries, each entry corresponding to a dot'"'"'s position, each entry further indicating whether a dot is a data dot or a constant dot, and accordingly each entry having either fixed data bits or variable data bits.

Abstract
A generic data package template is described that allows data to be encoded and printed in any arbitrary shape using an arbitrary encoding scheme. The template comprises an arbitrary shaped constant background pattern that is read to locate and orient a data area. The data are contains a plurality of dots that are decoded to extract the stored information.
