php使用Imagick生成图片的方法
这篇文章主要介绍了php使用Imagick生成图片的方法,实例分析了php基于Imagick实现添加水印、文字的图片功能,具有一定参考借鉴价值,需要的朋友可以参考下。
本文实例讲述了php使用Imagick生成图片的方法,分享给大家供大家参考,具体如下:
这里使用Imagick 生成图片
解决了图片写中文文字乱码问题,添加支持的字体
- public function getPic(){
- header('Content-Type: text/html; charset=utf-8');
- $text = '中粮屯河(sh600737)';//中粮屯河(sh600737)
- $watermark = '305988103123zczcxzas';
- $len = strlen($text);
- $width = 10.5*(($len-8)/3*2+8);
- $height = 26;
- $imagick = new Imagick();
- $color_transparent = new ImagickPixel('#ffffff'); //transparent 透明色
- $imagick->newImage($width, $height, $color_transparent, 'jpg');
- //$imagick->borderimage('#000000', 1, 1);
- $style['font_size'] = 12;
- $style['fill_color'] = '#000000';
- for($num= strlen($watermark); $num>=0; $num--){
- $this->add_text($imagick,substr($watermark, $num,1), 2+($num*8), 30, 1,$style);
- $this->add_text($imagick,substr($watermark, $num,1), 2+($num*8), 5, 1,$style);
- }
- //return;
- $style['font_size'] = 20;
- $style['fill_color'] = '#FF0000';
- $style['font'] = './msyh.ttf'; ///微软雅黑字体 解决中文乱码
- //$text=mb_convert_encoding($text,'UTF-8'); //iconv("GBK","UTF-8//IGNORE",$text);
- $this->add_text($imagick,$text, 2, 20, 0,$style);
- header ( 'Content-type: ' . strtolower ($imagick->getImageFormat ()) );
- echo $imagick->getImagesBlob ();
- }
- // 添加水印文字
- public function add_text(& $imagick, $text, $x = 0, $y = 0, $angle = 0, $style = array()) {
- $draw = new ImagickDraw ();
- if (isset ( $style ['font'] ))
- $draw->setFont ( $style ['font'] );
- if (isset ( $style ['font_size'] ))
- $draw->setFontSize ( $style ['font_size'] );
- if (isset ( $style ['fill_color'] ))
- $draw->setFillColor ( $style ['fill_color'] );
- if (isset ( $style ['under_color'] ))
- $draw->setTextUnderColor ( $style ['under_color'] );
- if (isset ( $style ['font_family'] ))
- $draw->setfontfamily( $style ['font_family'] );
- if (isset ( $style ['font'] ))
- $draw->setfont($style ['font'] );
- $draw->settextencoding('UTF-8');
- if (strtolower ($imagick->getImageFormat ()) == 'gif') {
- foreach ( $imagick as $frame ) {
- $frame->annotateImage ( $draw, $x, $y, $angle, $text );
- }
- } else {
- $imagick->annotateImage ( $draw, $x, $y, $angle, $text );
- }
- }
