使用imagick编写平铺整个图的水印
同事前一段时间用imagemagick命令行搞了一个水印，就改写成imagick形式。
imagemagic 官方去除图片背景的命令行模式
- convert -size 140x80 xc:none -fill grey \
- -gravity NorthWest -draw "text 10,10 'Copyright'" \
- -gravity SouthEast -draw "text 5,15 'Copyright'" \
- miff:- |\
- composite -tile - logo.jpg wmark_text_tiled.jpg
PHP代码 imagick写法
- <?PHP
- $image = new Imagick('logo.jpg');
- $im = new Imagick();
- $im->newImage( 140, 80, new ImagickPixel( "none" ) );
- $draw = new ImagickDraw();
- $draw->setFillColor(new ImagickPixel( "grey" ));
- $draw->setGravity(imagick::GRAVITY_NORTHWEST);
- $draw->annotation(10,10 ,'Copyright');
- $draw->setGravity(imagick::GRAVITY_SOUTHEAST);
- $draw->annotation(5,15 ,'Copyright');
- $im->drawImage( $draw);
- $image = $image->textureImage($im);
- $image->compositeImage($image,imagick::COMPOSITE_COPY,0,0);
- header( "Content-Type: image/{$image->getImageFormat()}" );
- $image->writeImage('wmark_text_tiled.jpg');
- $image->clear();
- $image->destroy();
- ?>
