::EDIT::
在@swordbeta 的帮助下,我的脚本正常工作了。以下是供将来参考的代码:
<?php
function buildThumbGallery(){
$curDir = "./Recent_Additions/";
$thumbsPath = $curDir."thumbs/";
if (!file_exists($thumbsPath)) {
mkdir($thumbsPath, 0777, true);
}
foreach(scandir($curDir) as $image){
if ($image === '.' || $image === '..' || $image === 'thumbs') continue;
if(!file_exists($thumbsPath.basename($image, ".jpg")."_thumb.jpg")){
// Max vert or horiz resolution
$maxsize=200;
// create new Imagick object
$thumb = new Imagick($curDir.$image); //'input_image_filename_and_location'
$thumb->setImageFormat('jpg');
// Resizes to whichever is larger, width or height
if($thumb->getImageHeight() <= $thumb->getImageWidth()){
// Resize image using the lanczos resampling algorithm based on width
$thumb->resizeImage($maxsize,0,Imagick::FILTER_LANCZOS,1);
}else{
// Resize image using the lanczos resampling algorithm based on height
$thumb->resizeImage(0,$maxsize,Imagick::FILTER_LANCZOS,1);
}
// Set to use jpeg compression
$thumb->setImageCompression(Imagick::COMPRESSION_JPEG);
$thumb->setImageCompressionQuality(100);
// Strip out unneeded meta data
$thumb->stripImage();
// Writes resultant image to output directory
$thumb->writeImage($thumbsPath.basename($image, ".jpg")."_thumb.jpg"); //'output_image_filename_and_location'
// Destroys Imagick object, freeing allocated resources in the process
$thumb->destroy();
}else{
echo '<a class="fancybox" data-fancybox-group="'.basename($curDir).'" href="'.$curDir.basename($image, "_thumb.jpg").'" title="Recent Addition - '.basename($image, ".jpg").'"><img src="'.$thumbsPath.basename($image, ".jpg")."_thumb.jpg".'"/></a>';
echo '<figcaption>'.basename($image, ".jpg").'</figcaption>' . "<br/>";
}
}
}
?>

好的,在返回并从@swordbeta 进行更多研究和建议之后,我得到了一些有用的东西。我现在唯一的问题是我无法在 index.php 中显示图像。稍后我将在 CSS 中设置输出样式,现在我只想查看缩略图,然后将它们构建到灯箱 href 链接中:
<?php
function buildThumbGallery(){
$curDir = "./Recent_Additions/";
$thumbsPath = $curDir."/thumbs/";
if (!file_exists($thumbsPath)) {
mkdir($thumbsPath, 0777, true);
}
$width = 200;
foreach(scandir($curDir) as $image){
if ($image === '.' || $image === '..') continue;
if(file_exists($thumbsPath.basename($image)."_thumb.jpg")){
continue;
}else{
// Max vert or horiz resolution
$maxsize=200;
// create new Imagick object
$thumb = new Imagick($curDir.$image); //'input_image_filename_and_location'
// Resizes to whichever is larger, width or height
if($thumb->getImageHeight() <= $thumb->getImageWidth()){
// Resize image using the lanczos resampling algorithm based on width
$thumb->resizeImage($maxsize,0,Imagick::FILTER_LANCZOS,1);
}else{
// Resize image using the lanczos resampling algorithm based on height
$thumb->resizeImage(0,$maxsize,Imagick::FILTER_LANCZOS,1);
}
// Set to use jpeg compression
$thumb->setImageCompression(Imagick::COMPRESSION_JPEG);
$thumb->setImageCompressionQuality(100);
// Strip out unneeded meta data
$thumb->stripImage();
// Writes resultant image to output directory
$thumb->writeImage($thumbsPath.basename($image)."_thumb.jpg"); //'output_image_filename_and_location'
// Destroys Imagick object, freeing allocated resources in the process
$thumb->destroy();
}
} echo '<img src="'.$thumbsPath.basename($image)."_thumb.jpg".'" />' . "<br/>";
}
?>
目前,echo 的输出没有显示任何内容,但脚本的其余部分工作正常(即在 thumbs 目录中生成缩略图)。
我猜我没有正确格式化我的回声。这个脚本在我的 index.php 中被称为 <?php buildThumbGallery(); ?> 在一个样式化的 <div> 标记内。
