I'm using the sfImageTransformPlugin in conjunction with the helpers
below:
/**
* Get the path of a generated thumbnail for any given image
*
* @param string $source
* @param int $width
* @param int $height
* @param boolean $absolute
* @return string
*/
function thumbnail_path($source, $width = null, $height = null,
$absolute = false)
{
$thumbnails_dir = sfConfig::get('app_sfThumbnail_thumbnails_dir',
'uploads/thumbnails');
$quality = sfConfig::get("app_sfThumbnail_quality", 90);
$width = intval($width);
$height = intval($height);
if (substr($source, 0, 1) == '/') {
$realpath = sfConfig::get('sf_web_dir') . $source;
} else {
$realpath = sfConfig::get('sf_web_dir') . '/images/' . $source;
}
$real_dir = dirname($realpath);
$thumb_dir = '/' . $thumbnails_dir . substr($real_dir,
strlen(sfConfig::get('sf_web_dir')));
$thumb_name = preg_replace('/^(.*?)(\..+)?$/', '$1_' . $width . 'x' .
$height . '$2', basename($source));
$img_from = $realpath;
$thumb = $thumb_dir . '/' . $thumb_name;
$img_to = sfConfig::get('sf_web_dir') . $thumb;
if (!is_dir(dirname($img_to))) {
if (!mkdir(dirname($img_to), 0777, true)) {
throw new Exception('Cannot create directory for
thumbnail : ' .
$img_to);
}
}
if (!is_file($img_to) || filemtime($img_from) > filemtime($img_to)) {
if(!sfConfig::get("app_sfThumbnail_safe_mode", true) ||
file_exists($img_from)) {
$thumbnail = new sfImage($img_from);
$thumbnail -> thumbnail($width, $height, 'scale');
$thumbnail -> setQuality($quality);
$thumbnail -> saveAs($img_to);
}
}
return image_path($thumb, $absolute);
}
/**
* Get the <img> tag to include a thumbnail into your web page
*
* @param string $source
* @param int $width
* @param int $height
* @param mixed $options
* @return string
*/
function thumbnail_tag($source, $width, $height, $options = array())
{
$img_src = thumbnail_path($source, $width, $height, false);
return image_tag($img_src, $options);
}
This way you can call thumbnail_tag('...path to image', 200, 200); and
the conversion is happening on the fly - once.
