Example #1 在 Imagick 中创建缩略图
<?php header(\'Content-type: image/jpeg\'); $image = new Imagick(\'image.jpg\'); // If 0 is provided as a width or height parameter, // aspect ratio is maintained $image->thumbnailImage(100, 0); echo $image; ?>
Example #2 Make a thumbnail of all JPG files in a directory
<?php
$images = new Imagick(glob(\'images/*.JPG\'));
foreach($images as $image) {
// Providing 0 forces thumbnailImage to maintain aspect ratio
$image->thumbnailImage(1024,0);
}
$images->writeImages();
?>
Example #3 Creating a reflection of an image
<?php /* Read the image */ $im = new Imagick(\"test.png\"); /* Thumbnail the image */ $im->thumbnailImage(200, null); /* Create a border for the image */ $im->borderImage(new ImagickPixel(\"white\"), 5, 5); /* Clone the image and flip it */ $reflection = $im->clone(); $reflection->flipImage(); /* Create gradient. It will be overlayed on the reflection */ $gradient = new Imagick(); /* Gradient needs to be large enough for the image and the borders */ $gradient->newPseudoImage($reflection->getImageWidth() + 10, $reflection->getImageHeight() + 10, \"gradient:transparent-black\"); /* Composite the gradient on the reflection */ $reflection->compositeImage($gradient, imagick::COMPOSITE_OVER, 0, 0); /* Add some opacity. Requires ImageMagick 6.2.9 or later */ $reflection->setImageOpacity( 0.3 ); /* Create an empty canvas */ $canvas = new Imagick(); /* Canvas needs to be large enough to hold the both images */ $width = $im->getImageWidth() + 40; $height = ($im->getImageHeight() * 2) + 30; $canvas->newImage($width, $height, new ImagickPixel(\"black\")); $canvas->setImageFormat(\"png\"); /* Composite the original image and the reflection on the canvas */ $canvas->compositeImage($im, imagick::COMPOSITE_OVER, 20, 10); $canvas->compositeImage($reflection, imagick::COMPOSITE_OVER, 20, $im->getImageHeight() + 10); /* Output the image*/ header(\"Content-Type: image/png\"); echo $canvas; ?>

Example #4 Filling text with gradient
<?php /* Create a new imagick object */ $im = new Imagick(); /* Create new image. This will be used as fill pattern */ $im->newPseudoImage(50, 50, \"gradient:red-black\"); /* Create imagickdraw object */ $draw = new ImagickDraw(); /* Start a new pattern called \"gradient\" */ $draw->pushPattern(\'gradient\', 0, 0, 50, 50); /* Composite the gradient on the pattern */ $draw->composite(Imagick::COMPOSITE_OVER, 0, 0, 50, 50, $im); /* Close the pattern */ $draw->popPattern(); /* Use the pattern called \"gradient\" as the fill */ $draw->setFillPatternURL(\'#gradient\'); /* Set font size to 52 */ $draw->setFontSize(52); /* Annotate some text */ $draw->annotation(20, 50, \"Hello World!\"); /* Create a new canvas object and a white image */ $canvas = new Imagick(); $canvas->newImage(350, 70, \"white\"); /* Draw the ImagickDraw on to the canvas */ $canvas->drawImage($draw); /* 1px black border around the image */ $canvas->borderImage(\'black\', 1, 1); /* Set the format to PNG */ $canvas->setImageFormat(\'png\'); /* Output the image */ header(\"Content-Type: image/png\"); echo $canvas; ?>

Example #5 Read in GIF image and resize all frames
<?php
/* Create a new imagick object and read in GIF */
$im = new Imagick(\"example.gif\");
/* Resize all frames */
foreach ($im as $frame) {
/* 50x50 frames */
$frame->thumbnailImage(50, 50);
/* Set the virtual canvas to correct size */
$frame->setImagePage(50, 50, 0, 0);
}
/* Notice writeImages instead of writeImage */
$im->writeImages(\"example_small.gif\", true);
?>
Example #6 Create a PHP logo
<?php /* Set width and height in proportion of genuine PHP logo */ $width = 400; $height = 210; /* Create an Imagick object with transparent canvas */ $img = new Imagick(); $img->newImage($width, $height, new ImagickPixel(\'transparent\')); /* New ImagickDraw instance for ellipse draw */ $draw = new ImagickDraw(); /* Set purple fill color for ellipse */ $draw->setFillColor(\'#777bb4\'); /* Set ellipse dimensions */ $draw->ellipse($width / 2, $height / 2, $width / 2, $height / 2, 0, 360); /* Draw ellipse onto the canvas */ $img->drawImage($draw); /* Reset fill color from purple to black for text (note: we are reusing ImagickDraw object) */ $draw->setFillColor(\'black\'); /* Set stroke border to white color */ $draw->setStrokeColor(\'white\'); /* Set stroke border thickness */ $draw->setStrokeWidth(2); /* Set font kerning (negative value means that letters are closer to each other) */ $draw->setTextKerning(-8); /* Set font and font size used in PHP logo */ $draw->setFont(\'Handel Gothic.ttf\'); $draw->setFontSize(150); /* Center text horizontally and vertically */ $draw->setGravity(Imagick::GRAVITY_CENTER); /* Add center \"php\" with Y offset of -10 to canvas (inside ellipse) */ $img->annotateImage($draw, 0, -10, 0, \'php\'); $img->setImageFormat(\'png\'); /* Set appropriate header for PNG and output the image */ header(\'Content-Type: image/png\'); echo $img; ?>
