我正在使用php Imagick库进行一些图像处理。我可以扭曲图像的视角,但不能使它们看起来像帆布或厕所

如果有人能解释我怎么能这样做会很棒。

我想我设法做了我想做的事。
这是我的方法
$im = new Imagick('Desert.jpg');
$im->setImageFormat('png');
$d = $im->getImageGeometry();
$w = $d['width'];
$h = $d['height'];
$im3 = new Imagick();
$im3->newImage(1, $h, 'none','png');
$im3->setImageVirtualPixelMethod(Imagick::VIRTUALPIXELMETHOD_TRANSPARENT);
$im1 = $im->clone();;
$im1->setImageVirtualPixelMethod(Imagick::VIRTUALPIXELMETHOD_TRANSPARENT);
$im1->setImageMatte(true);
$im1->cropImage(($w-10), $h, 0, 0);
$controlPoints = array(
0,0, 15,15,
($w-10),0, ($w-10),0,
0,$h, 25,($h-20),
($w-10),$h, ($w-10),$h
);
$im1->distortImage(Imagick::DISTORTION_BILINEAR, $controlPoints, true);
$im2 = $im->clone();
$im2->setImageVirtualPixelMethod(Imagick::VIRTUALPIXELMETHOD_TRANSPARENT);
$im2->setImageMatte(true);
$im2->cropImage(10, $h, ($w-10), 0);
$controlPoints2 = array(
0,0, 0,0,
10,0,10,10,
0,$h, 0,$h,
10,$h, 10,($h-10)
);
$im2->distortImage(Imagick::DISTORTION_BILINEAR, $controlPoints2, true);
$image = new Imagick();
$image->addImage($im1);
$image->addImage($im3);
$image->addImage($im2);
$image->resetIterator();
$combined = $image->appendImages(false);
$shadow = $combined->clone();
$shadow->setImageBackgroundColor( new ImagickPixel( 'black' ) );
$shadow->shadowImage( 50, 3, 5, 5 );
$shadow->compositeImage( $combined, Imagick::COMPOSITE_OVER, 0, 0 );
$shadow->writeImage('Desert_Distorded.png');
,最终结果是
