PHP生成条形码-开源之道

该软件支持PHP4和PHP5两个版本，本文中使用的是PHP5的版本。在使用前注意要将PHP的GD模块开启。在Windows中为php_gd2.dll，Linux中为gd.so。将压缩文件解压到Apache，执行="test.php?codebar=BCGcode39&text=20090729">

效果图：

Test.php代码如下：
 <?php
// Including all required classes
require('class/BCGFont.php');
require('class/BCGColor.php');
require('class/BCGDrawing.php');
/*'BCGcodabar','BCGcode11','BCGcode39','BCGcode39extended','BCGcode93',
'BCGcode128','BCGean8','BCGean13','BCGisbn','BCGi25','BCGs25','BCGmsi',
'BCGupca','BCGupce','BCGupcext2','BCGupcext5','BCGpostnet','BCGothercode'*/
$codebar = $_REQUEST['codebar']; //该软件支持的所有编码，只需调整$codebar参数即可。
// Including the barcode technology
include('class/'.$codebar.'.barcode.php');
// Loading Font
$font = new BCGFont('./class/font/Arial.ttf', 10);
// The arguments are R, G, B for color.
$color_black = new BCGColor(0, 0, 0);
$color_white = new BCGColor(255, 255, 255);
$code = new $codebar();
$code->setScale(2); // Resolution
$code->setThickness(30); // Thickness
$code->setForegroundColor($color_black); // Color of bars
$code->setBackgroundColor($color_white); // Color of spaces
$code->setFont($font); // Font (or 0)
$text = $_REQUEST['text']; //条形码将要数据的内容
$code->parse($text);
/* Here is the list of the arguments
1 - Filename (empty : display on screen)
2 - Background color */
$drawing = new BCGDrawing('', $color_white);
$drawing->setBarcode($code);
$drawing->draw();
// Header that says it is an image (remove it if you save the barcode to a file)
header('Content-Type: image/png');
// Draw (or save) the image into PNG format.
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);
?>
