PHP Imagick：转换ImageMagick命令行代码时出现问题

2024-05-10 • 问答

我在Windows 8.1上使用ImageMagick 7.0.8-66 Q16 x64 我的PHP在XAMPP上是7.4.1。

我已经在PHP中使用exec（）成功运行了以下命令：

convert _temp_.jpg 
( +clone -background black -shadow 88x3+2+2 ) 
+swap -background none -layers merge 
+repage -background #eeeeee -layers flatten 
+repage -shave 3x3 
( -size 100x100 xc:#eeeeee ) 
+swap -gravity northwest -geometry +5+5 -compose over -composite output.jpg

它会拍摄图像，将其调整大小以适合100x100的缩略图，并在中性的#eeeeee背景画布上为图像添加阴影。可以。

我想重写它以使用Imagick PHP扩展，但是在翻译时遇到了麻烦。这是我翻译它（带有注释）的方法，该方法不起作用：

// convert _temp_.jpg 
$im = new imagick();
$im->readImage('_temp_.jpg');

// ( +clone -background black -shadow 88x3+2+2 ) 
$im_clone = clone $im;
$im_clone->setImageBackgroundColor('black');
$im_clone->shadowImage(88,3,2,2);

// +swap -background none -layers merge 
$im->setImageBackgroundColor('none');
$im->addImage($im_clone);
$im->mergeImageLayers(imagick::LAYERMETHOD_MERGE);

// +repage -background #eeeeee -layers flatten 
$im->cropImage(88,88,+5,+5);
$im->setImagePage(88,0);
$im->setImageBackgroundColor('#eeeeee');
$im->mergeImageLayers(imagick::LAYERMETHOD_flaTTEN);

// +repage -shave 3x3 
$im->cropImage(88,0);
$im->shaveImage(3,3);

// ( -size 100x100 xc:#eeeeee )
$im_pseudo = new Imagick();
$im_pseudo->newPseudoImage(100,100,'xc:#eeeeee');

// +swap -gravity northwest -geometry +5+5 -compose over -composite output.jpg
$im->setImageGravity(imagick::GRAVITY_NORTHWEST);
$im->compositeImage($im_pseudo,Imagick::COMPOSITE_OVER,5,5);

$im->writeImage('output.jpg');

我想念什么？

源图像：

生成的图像：

/* Read the image into the object */ $im = new Imagick( 'DOqeZ.jpg' ); $im->setImageFormat("png"); /* Make the image a little smaller,maintain aspect ratio */ $im->thumbnailImage( 200,null ); /* Clone the current object */ $shadow = $im->clone(); /* Set image background color to black (this is the color of the shadow) */ $shadow->setImageBackgroundColor( new ImagickPixel( 'black' ) ); /* Create the shadow */ $shadow->shadowImage( 80,3,5,5 ); /* Imagick::shadowImage only creates the shadow. That is why the original image is composited over it */ $shadow->compositeImage( $im,Imagick::COMPOSITE_OVER,0 ); /* Display the image */ $shadow->writeImage('shadow.png');

/* Read the image into the object */ $im = new Imagick( 'DOqeZ.jpg' ); $im->setImageFormat("png"); /* Make the image a little smaller,maintain aspect ratio */ $im->thumbnailImage( 80,0 ); /* Create the background image 100x100 with a background colour */ /* Gravity seems to have no effect */ /* $shadow->setImageGravity(imagick::GRAVITY_CENTER);*/ $shadow->setImageBackgroundColor( '#eeeeee' ); $height = $shadow->getImageHeight(); $width = $shadow->getImageWidth(); $shadow->extentImage( 100,100,(((100 - $width)/2)*-1 ),(((100 - $height)/2)*-1 )); $shadow->writeImage('shadow.jpg');
