Adopted for FMX framework by Fast Reports in 2013.
Barcode Component
Version 1.25 (15.05.2003)
Copyright 1998-2003 Andreas Schmidt and friends
Adapted to FR: Alexander Tzyganenko
for use with Delphi 1 - 7
Delphi 1 not tested; better use Delphi 2 (or higher)
Freeware
Feel free to distribute the component as
long as all files are unmodified and kept together.
I'am not responsible for wrong barcodes.

History:
----------------------------------------------------------------------
Version 1.0:
- initial release
Version 1.1:
- more comments
- changed function Code_93Extended (now correct ?)
Version 1.2:
- Bugs (found by Nikolay Simeonov) removed
Version 1.3:
- EAN8/EAN13 added by Wolfgang Koranda (wkoranda@csi.com)
Version 1.4:
- Bug (found by Norbert Waas) removed
Component must save the Canvas-properties Font,Pen and Brush
Version 1.5:
- Bug (found by Richard Hugues) removed
Last line of barcode was 1 Pixel too wide
Version 1.6:
- new read-only property 'Width'
Version 1.7
- check for numeric barcode types
- compatible with Delphi 1 (i hope)
Version 1.8
- add Color and ColorBar properties
Version 1.9
- Code 128 C added by Jan Tungli
Version 1.10
- Bug in Code 39 Character I removed
Version 1.11 (06.07.1999)
- additional Code Types
CodeUPC_A,
CodeUPC_E0,
CodeUPC_E1,
CodeUPC_Supp2,
CodeUPC_Supp5
by Jan Tungli
Version 1.12 (13.07.1999)
- improved ShowText property by Mauro Lemes
you must change your applications due changed interface of TBarcode.
Version 1.13 (23.07.1999)
- additional Code Types
CodeEAN128A,
CodeEAN128B,
CodeEAN128C
(support by Norbert Kostka)
- new property 'CheckSumMethod'
Version 1.14 (29.07.1999)
- checksum for EAN128 by Norbert Kostka
- bug fix for EAN128C
Version 1.15 (23.09.1999)
- bug fix for Code 39 with checksum by Frank De Prins
Version 1.16 (10.11.1999)
- width property is now writable (suggestion by Shane O'Dea)
Version 1.17 (27.06.2000)
- new OnChange property
- renamed TBarcode to TAsBarcode to avoid name conflicts
Version 1.18 (25.08.2000)
- some speed improvements (Code 93 and Code 128)
Version 1.19 (27.09.2000)
(thanks to Samuel J. Comstock)
- origin of the barcode (left upper edge) is moved so that
the barcode stays always on the canvas
- new (read only) properties 'CanvasWidth' and 'CanvasHeight' gives you
the size of the resulting image.
- a wrapper class for Quick Reports is now available.
Version 1.20 (13.09.2000)
- Assign procedure added
- support for scaling barcode to Printer (see Demo)
Version 1.21 (19.07.2001)
(thanks to Roberto Parola)
- new properties ShowTextFont and ShowTextPosition
Version 1.22 (26.10.2001)
- Code 128 Symbol #12 (=comma) fixed (thanks to Stefano Torricella)
Version 1.23 (13.11.2002)
- UPC_E0 and UPC_E1 stopcodes fixed (thanks to Duo Dreamer)
Version 1.24 (04.12.2002)
- Bugfix for Code93 Extended
Version 1.25 (15.05.2003)
- fixed a bug in procedure Assign (thanks to Mariusz Mialkon)
Todo (missing features)
-----------------------
- more CheckSum Methods
- user defined barcodes
- checksum event (fired when the checksum is calculated)
- rename the unit name (from 'barcode' to 'fbarcode') to avoid name conflicts
- I'am working on PDF417 barcode (has anybody some technical information about PDF417
or a PDF417 reader ?)
Known Bugs
---------
- Top and Left properties must be set at runtime.
- comments not compatible with Delphi 1

A barcode begins always with a black line and

The white Lines builds the space between the black Lines.
A black line must always followed by a white Line and vica versa.

'50505' // 3 thin black Lines with 2 thin white Lines
'606' // 2 fat black Lines with 1 thin white Line
'5605015' // Error
