This folder contains some extra tools to provide functionality which
|
||||
may be useful, or just interesting, but fall outside the remit of the
|
||||
Zint program. These small programs have been written by Robin Stuart
|
||||
and are released to the public domain.
|
||||
|
||||
Font Encoding Tools
|
||||
-------------------
|
||||
daft.c
|
||||
ida_2d.c
|
||||
stroke.c
|
||||
zebu_pdf.c
|
||||
|
||||
These code snippets show how Zint can be used to create the text
|
||||
necessary to display symbols using a range of fonts available online.
|
||||
See the individual files for information about the specific fonts.
|
||||
Some of these fonts are free whereas others require licensing, check the
|
||||
specific websites before use.
|
||||
|
||||
Obsolete Symbologies
|
||||
--------------------
|
||||
cuecat.c
|
||||
kartrak.c
|
||||
sunburst.c
|
||||
|
||||
These are stand-alone tools for encoding data in some more obscure and
|
||||
obsolete formats. More information is given within the file.

* cuecat.c
|
||||
*
|
||||
* This code creates barcodes as intended for use with the CueCat scheme (without the
|
||||
* "cue" symbol which may still be trademarked). As the system was ultimately not
|
||||
* successful this is now simply a curiosity.
|
||||
*
|
||||
* "The CueCat, styled :CueCat with a leading colon, is a cat-shaped handheld barcode
|
||||
* reader that was released in 2000 by the now-defunct Digital Convergence Corporation.
|
||||
* The CueCat enabled a user to open a link to an Internet URL by scanning a barcode —
|
||||
* called a "cue" by Digital Convergence — appearing in an article or catalog or on
|
||||
* some other printed matter."
