$average->uniqueImageColors();
function GetImagesColor( Imagick $im ){
$colorarr = array();
$it = $im->getPixelIterator();
$it->resetIterator();
while( $row = $it->getNextIteratorRow() ){
foreach ( $row as $pixel ){
$colorarr[] = $pixel->getColor();
}
}
return $colorarr;
}
$colorarr = GetImagesColor($average);
foreach($colorarr as $val){
echo "<div style='background-color: rgb({$val['r']},{$val['g']},{$val['b']});width:50px;height:50px;float:left;'></div>
";
}

我想实现用get提交图片url地址来读取图片主色值，可是这样写会报错，怎么破？

Answer 1

$average = new Imagick("$_GET ["url"];");

这里报错 是因为你参数错误 $average = new Imagick($_GET ["url"]); 就可以了

Answer 2

if rv is not None and rsv is not None:
# extract version/subversion
self._nmap_version_number = int(line[rv.start():rv.end()])
self._nmap_subversion_number = int(line[rsv.start()+1:rsv.end()])
break
}

Answer 3

分号分号，注意格式

Answer 4

参数URL语法错误导致的。重点输出断点查看URL参数调试。

Answer 5

$average = new Imagick("$_GET ["url"];");
$average = new Imagick($_GET ["url"]);
