php获取图片RGB颜色值的例子，

<span>$average</span> = <span>new</span> Imagick("xiaocai.jpg"<span>);

</span><span>$average</span>->quantizeImage( 10, Imagick::COLORSPACE_RGB, 0, <span>false</span>, <span>false</span><span> );

</span><span>$average</span>-><span>uniqueImageColors();

</span><span>function</span> GetImagesColor( Imagick <span>$im</span><span> ){

</span><span>$colorarr</span> = <span>array</span><span>();

</span><span>$it</span> = <span>$im</span>-><span>getPixelIterator();

</span><span>$it</span>-><span>resetIterator();

</span><span>while</span>( <span>$row</span> = <span>$it</span>-><span>getNextIteratorRow() ){

</span><span>foreach</span> ( <span>$row</span> <span>as</span> <span>$pixel</span><span> ){
// www.jbxue.com
</span><span>$colorarr</span>[] = <span>$pixel</span>-><span>getColor();

}

}

</span><span>return</span> <span>$colorarr</span><span>;

}

</span><span>$colorarr</span> = GetImagesColor(<span>$average</span><span>);

</span><span>foreach</span>(<span>$colorarr</span> <span>as</span> <span>$val</span><span>){

</span><span>echo</span> "<div style='background-color: rgb({<span>$val</span>['r']},{<span>$val</span>['g']},{<span>$val</span>['b']});width:50px;height:50px;float:left;'></div>"<span>;

}</span><span> </span>
