PHP的ImageMagick使用；

$img =new Imagick();
$img->newImage(500,300,'black','png')

$height=$img->getImageHeight();//获取图片1高度
$width=$img->getImageWidth();//获取图片1宽度

$imgtwo->resizeImage($width,$height,Imagick::FILTER_LANCZOS,1);

bool Imagick::resizeImage ( int $columns , int $rows , int $filter , float $blur [, bool $bestfit = false ] )

bool Imagick::compositeImage ( Imagick $composite_object , int $composite , int $x , int $y [, int $channel = Imagick::CHANNEL_ALL ] )

$img->compositeImage($imgtwo,$image->getImageCompose(),0,0)

header("Content-Type: image/png");
echo $img;

在当年目录下生成为img.png
$file="./img.png";
$img->writeImage($file);
这样就会在当前目录下生成图片img.png;

$draw=new ImagickDraw();

$draw->setFillColor(new ImagickPixel('white'));

$draw->setFontSize('25');

$draw->setFont("../fonts/Arial.ttf");

$draw->setTextAlignment(Imagick::ALIGN_RIGHT);

$draw->setTextEncoding("utf-8")

$draw->annotation(200,200,'GDP')；

$img->drawImage($draw)；

$img->cropImage(300, 300, 0, 20);

$img->roundCorners(60, 60);
