imagemagic官方去除图片背景的命令行模式：

代码如下 复制代码
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


imagick代码：

代码如下 复制代码
$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();
?>
