该扩展是基于ImageMagick基础实现的，图片操作调用的是ImageMagick API。 一、类文档说明 class Image_Tool{ /** * 构造Image_Tool对象 * @param string|array $img_data * $img_data可以为图片的路径 */function __construct($img_data=); /** * 添加文字注
该扩展是基于ImageMagick基础实现的，图片操作调用的是ImageMagick API。
一、类文档说明
class Image_Tool{
/**
* 构造Image_Tool对象
* @param string|array $img_data
* $img_data可以为图片的路径
*/
function __construct($img_data="");
/**
* 添加文字注解，或用于文字水印
* @access public
* @param string $txt UTF8编码的文本
* @param float $opacity 设置透明度
* @param constant $gravity
* 设置文字摆放位置:
* NorthWest,North,NorthEast,West, Center,East,SouthWest,South,SouthEast,Static
* @param array $font 字体数组可以设置如下属性:
* name,常量,字体名称，如果需要添加中文注解，请使用中文字体，否则中文会显示乱码。
* 支持的字体：SimSun(宋体,默认)、SimKai(楷体)、SimHei(正黑)、MicroHei(微米黑)、Arial
* weight,字体宽度,int
* size，字体大小,int
* color,字体颜色,例如："blue", "#0000ff", "rgb(0,0,255)"等，默认为"black";
* @return boolean
*/
function annotate($txt, $opacity, $gravity, array $font);
/**
* 将对象的数据重新初始化,用于多次重用一个Image_Tool对象
* @access public
* @return void
*/
function clean();
*
* 图片合成，可以进行多张图片的合成，也可以做图片水印用
* @access public
* @param int $src_img 合成的目标图片，可以为ImageTool对象或图片二进制数据
* @param int $x 合成在画布的X坐标
* @param string $y 合成在画布的Y坐标
* @return boolean
*
function composite($src_img, $x, $y);
/**
* 返回错误信息
* @access public
* @return string
*/
function errmsg();
/**
* 返回错误编号
* @access public
* @return int
*/
function errcode();
/**
* 进行图片处理操作
* @access public
* @param string $format
* @param boolean $display
* @return boolean|string 若设置$display为true，返回void，否则返回图片二进制数据。失败时返回false
*/
function exec($format, $display=false);
/**
* 水平翻转
* @access public
* @return boolean
*/
function flipH();
/**
* 垂直翻转
* @access public
* @return boolean
*/
function flipV();
/**
* 取得图片属性
* @access public
* @return array|boolean 错误返回false
*/
function getImageAttr();
/**
* 去噪点,改善图片质量，通常用于exec之前
* @access public
* @return boolean
*/
function improve();
/**
* 缩放图片,只指定width或者height时,将进行等比缩放
* @access public
* @param int $width
* @param int $height
* @param boolean $thumbnail 是否清除图片附加信息
* @return boolean
*/
function resize($width, $height, $thumbnail=true);
/**
* 按比例缩放.1为原大小
* @access public
* @param float $ratio
* @param boolean $thumbnail 是否清除图片附加信息
* @return boolean
*/
function resizeRatio($ratio, $thumbnail=true);
/**
* 顺时针旋转图片
* @access public
* @param int $degree 旋转度数（0 - 360）
* @return boolean
*/
function rotate($degree=90);
/**
* 设置要处理的图片二进制数据
* @access public
* @param string $img_blob
* @return boolean
*/
function setData($img_blob);
}
二、使用案例
$img1 = new Image_Tool("C:/Users/Administrator/Desktop/1.jpg");
$font = array('name'=>'Simsun', 'color'=>'red', 'size'=>20, 'weight'=>900);
$img1->annotate('Good Bye!', 0.1, IMAGETOOL_NORTHWEST, $font); //打上文字水印
// $img1->rotate(90);
$img1->flipV();//垂直翻转
// $img1->resize(250, 250, 0);
$img1->resizeRatio(0.5, 1);
$img_arr = $img1->getImageAttr();//图片属性 宽、高、类型
$img1->improve();//除噪点
$img2 = new Image_Tool();
$img2->setData(file_get_contents("C:/Users/Administrator/Desktop/3.png"));
$background_img = new Image_Tool("C:/Users/Administrator/Desktop/2.png");
$background_img->composite($img1, 200, 100); //以background_img为画布，基于左上角0,0坐标开始向右200、向下100像素将图片img1合成
$background_img->composite($img2, 0, 0); //将background_img与img1合成后的图片，基于左上角0,0点合成img2
$background_img->exec("C:/Users/Administrator/Desktop/composite.jpg");//生成三张图片合并后的新图片
三、扩展实现
