+# Alfresco-Zxing-Reader
+Uses the Zxing (Zebra Crossing) java libraries to decode bar codes and QR codes in documents.
+Currently works for PDF and PNG files only.
+
+A custom aspect (bcode:barCoded) contains a single property (bcode:barCodeText) of type d:text is added.
+Retrieval of the bar/QR code text is through a custom action (get-barcode).
+
+Share customization includes the action being added to the document list actions (PDF and PNG only) and the 
+addition of an indicator showing those files with the barCoded aspect.
+
+Limitations:
+PDF and PNG only (should be easy to add other types if needed).
+Only looks on the first page of the document for valid code.
+Retrieves only one code per page/document (seems to be the one closest to the center of the page)
