// PDF_Label
//
// Class to print labels in Avery or custom formats
//
// Copyright (C) 2003 Laurent PASSEBECQ (LPA)
// Based on code by Steve Dillon
//---------------------------------------------------------------------------------------------
// VERSIONS:
// 1.0: Initial release
// 1.1: + Added unit in the constructor
// + Now Positions start at (1,1).. then the first label at top-left of a page is (1,1)
// + Added in the description of a label:
// font-size : defaut char size (can be changed by calling Set_Char_Size(xx);
// paper-size: Size of the paper for this sheet (thanx to Al Canton)
// metric : type of unit used in this description
// You can define your label properties in inches by setting metric to
// 'in' and print in millimiters by setting unit to 'mm' in constructor
// Added some formats:
// 5160, 5161, 5162, 5163, 5164: thanks to Al Canton
// 8600 : thanks to Kunal Walia
// + Added 3mm to the position of labels to avoid errors
// 1.2: = Bug of positioning
// = Set_Font_Size modified -> Now, just modify the size of the font
// 1.3: + Labels are now printed horizontally
// = 'in' as document unit didn't work
// 1.4: + Page scaling is disabled in printing options
// 1.5: + Added 3422 format
