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 );

}

}
