PHP implementation of the Watermark class, support to add pictures, text, fill the color area

This article mainly introduces the implementation of PHP watermark class, support to add pictures, text, fill the color area, interested in the reference of friends, I hope to be helpful to everyone.

* Self-organizing a watermark class *

Support for adding picture, text, fill color area

<?php/** * Image plus watermark class, support text watermark, transparency settings, custom watermark location and so on.       * Use Example: * $obj = new Watermask ($imgFileName);           Instantiated Object * $obj $waterType = 1;         Type: 0 for text watermark, 1 for picture watermark * $obj $transparent = 45;        Watermark Transparency * $obj $waterStr = ' icp.niufee.com ';           Watermark Text * $obj-$fontSize = 18;        Text font size * $obj $fontColor = array (255,255,255);       Watermark text Color (RGB) * $obj $fontFile = ' Ahgbold.ttf ';              Font file * ... * $obj->output ();                Output watermark picture file overlay to input picture file * @modify liuzp111 */class watermask{public $waterTypeImage = false;          Watermark type: Enable picture watermark public $waterTypeStr = false;          Watermark Type: Enable text watermark public $pos = 0;         Watermark Location Public $transparent = 45;      Watermark Transparency (0---100) the larger the value the more opaque public $waterStr = ' icp.niufee.com ';         Watermark Text Public $fontSize = 14;          Text font size Public $fontColor = Array (0,0,0);      Watermark text color (RGB) Default black public $fontFile = './font/simfang.ttf '; Font file Public $waterimg = ' logo.png ';         Watermark Image Private $srcImg = ';         Images that need to be added to the watermark private $im = ';         Picture handle private $water _im = ';         Watermark Picture handle private $srcImg _info = ";         Picture information private $WATERIMG _info = ";         Watermark Picture information private $str _w = ";         Watermark Text Width private $str _h = ";         Watermark Text Height private $x = ';         Watermark x Coordinate private $y = ';                  Watermark y-coordinate public $output _img = ";                  Store the output picture to where public $is _draw_rectangle = false;                  Whether to draw a rectangular region (no custom position is currently supported)//public $rectange _color = ";               Draws the color of the rectangular area private $result _array = Array ();  Result array Public function __construct ($img) {//destructor//$this->srcimg = file_exists ($img)? $img: Die (' "'. $img.

How to use:

$file = ' 58368dddc8c51_22 ';//need to add watermark picture $file_ext = '. jpeg ';//extension $imgfilename = './'. $file. $file _ext;//need to add a watermark to the image path $obj = New Watermask ($imgFileName); Instantiate object $obj->watertypestr = true;     Turn on text watermark      $obj->watertypeimage = true;    Open image watermark  $obj->pos = 9;         Define watermark Picture location $obj->waterimg = './water.png ';      Watermark Picture     $obj->transparent =;          Watermark Transparency $obj->waterstr = ' Insurance broker: Liu Test Phone: 02052552 ';       Watermark Text $obj->fontsize = 9;            Text font Size $obj->fontcolor = Array (0,0,0);        Watermark text color (RGB) $obj->fontfile = './FONT/MSYH.TTC ';    Font file, here is Microsoft Jas Black $obj->is_draw_rectangle = TRUE;      Open the Draw rectangle area $obj->output_img = './'. $file. ' _n '. $file the picture path of the _ext;//output $obj->output ();
