PHP 圖檔處理類(水印、透明度、縮放、相框、銳化、旋轉、翻轉、剪切、反色)

最新PHP 圖檔處理類(水印、透明度、縮放、相框、銳化、旋轉、翻轉、剪切、反色)

以下是三零網為大家整理的最新PHP 圖檔處理類(水印、透明度、縮放、相框、銳化、旋轉、翻轉、剪切、反色)的文章，希望大家能夠喜歡!

可實作圖檔的縮放、剪切、相框、水印、銳化、旋轉、翻轉、透明度、反色功能操作。

<?php

/**

* 圖檔處理函數功能：縮放、剪切、相框、水印、銳化、旋轉、翻轉、透明度、反色

* 處理并儲存曆史記錄的思路：當有圖檔有改動時自動生成一張新圖檔，命名方式可以考慮在原圖檔的基礎上加上步驟，例如：圖檔名稱+__第幾步

class picture{

var $PICTURE_URL; //要處理的圖檔

var $DEST_URL = "temp__01.jpg"; //生成目标圖檔位置

var $PICTURE_CREATE; //要建立的圖檔

var $TURE_COLOR; //建立一個真彩圖象

var $PICTURE_WIDTH; //原圖檔寬度

var $PICTURE_HEIGHT; //原圖檔高度

/**

* 水印的類型，預設的為水印文字

var $MARK_TYPE = 1;

var $WORD; //經過UTF-8後的文字

var $WORD_X; //文字橫坐标

var $WORD_Y; //文字縱坐标

var $FONT_TYPE; //字型類型

var $FONT_SIZE = "12"; //字型大小

var $FONT_WORD; //文字

var $ANGLE = 0; //文字的角度，預設為0

var $FONT_COLOR = "#000000"; //文字顔色

var $FONT_PATH = "font/simkai.ttf"; //字型庫，預設為宋體

var $FORCE_URL; //水印圖檔

var $FORCE_X = 0; //水印橫坐标

var $FORCE_Y = 0; //水印縱坐标

var $FORCE_START_X = 0; //切起水印的圖檔橫坐标

var $FORCE_START_Y = 0; //切起水印的圖檔縱坐标

var $PICTURE_TYPE; //圖檔類型

var $PICTURE_MIME; //輸出的頭部

* 縮放比例為1的話就按縮放高度和寬度縮放

var $ZOOM = 1; //縮放類型

var $ZOOM_MULTIPLE; //縮放比例

var $ZOOM_WIDTH; //縮放寬度

var $ZOOM_HEIGHT; //縮放高度

* 裁切，按比例和固定長度、寬度

var $CUT_TYPE = 1; //裁切類型

var $CUT_X = 0; //裁切的橫坐标

var $CUT_Y = 0; //裁切的縱坐标

var $CUT_WIDTH = 100; //裁切的寬度

var $CUT_HEIGHT = 100; //裁切的高度

* 銳化

var $SHARP = "7.0"; //銳化程度

* 透明度處理

var $ALPHA = '100'; //透明度在0-127之間

var $ALPHA_X = "90";

var $ALPHA_Y = "50";

* 任意角度旋轉

var $CIRCUMROTATE = "90.0"; //注意，必須為浮點數

* 出錯資訊

var $ERROR = array(

'unalviable' => '沒有找到相關圖檔!'

);

* 構造函數：函數初始化

function __construct($PICTURE_URL){

$this -> get_info($PICTURE_URL);

}

function get_info($PICTURE_URL){

/**
