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 );
}
}
希望本文所述对大家的php程序设计有所帮助。
