Alternative method for storing image variations

[ZGD]

Not sure if this has been discussed before, but is it possible to use a different method for storing image variations with PW? For example, would it be possible that instead of storing variations like this:

/image.jpg
/image.2000x0.jpg
/image.0x900.jpg

Variations were instead stored like this:

/image.jpg
/2000x0/image.jpg
/0x900/image.jpg

Normally the default method is fine, but we are working on a project where the image filenames may need to remain unchanged, but variations still produced.

If anyone has any information about this it would be much appreciated!

EDIT: Having looked at the size method in the Pageimage class, it looks like this isn't something that could be changed easily.

no idea if that could work, but maybe you could use htaccess rewrite rules to achieve something like this?!

The built-in image sizing methods are convenient but they're not the only way to resize an image. You could use a third-party PHP library such as WideImage and save your images with any naming or directory structure you need.

module alert!

Turns out it's not difficult to do this using the core ImageSizer. Here's a function showing the basics - could be turned into a module, enhanced with some error checking, etc.

/**
 * Resize Pageimage using custom name/path
 *
 * @param Pageimage $pageimage
 * @param int $width
 * @param int $height
 * @param array $options
 *
 * @return string
 * 
 */
function resizeImage($pageimage, $width = 0, $height = 0, $options = array()) {
    $filename = $pageimage->filename();
    $basename = $pageimage->basename();
    $path = rtrim($filename, $basename);
    $dirname = $width . 'x' . $height;
    $variation_name = $path . $dirname . '/' . $basename;
    $variation_url = rtrim($pageimage->url(), $basename) . $dirname . '/' . $basename;

    $force_new = isset($options['forceNew']) ? $options['forceNew'] : false;
    if(!file_exists($variation_name) || $force_new) {
        wire('files')->mkdir($path . $dirname . '/');
        copy($filename, $variation_name);
        $sizer = new ImageSizer($variation_name);
        $sizer->setOptions($options);
        $sizer->resize($width, $height);
        wire('files')->chmod($variation_name);
    }

    return $variation_url;
}

// example
$image = $page->images->first();
$src = resizeImage($image, 500, 300);
echo "<img src='$src'>";

Could be turned into an optional core feature  Thanks for sharing anyway!
