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
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+($num*8),30,$style);
$this->add_text($imagick,5,$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,$text,2,20,$style);
header ( 'Content-type: ' . strtolower ($imagick->getimageFormat ()) );
echo $imagick->getimagesBlob ();
}
// 添加水印文字
public function add_text(& $imagick,$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 ( $draw,$text );
}
}
希望本文所述对大家的PHP程序设计有所帮助。
