PHP Documentation

<?php
/**
				 * Filters the JPEG compression quality for backward-compatibility.
				 *
				 * Applies only during initial editor instantiation, or when set_quality() is run
				 * manually without the `$quality` argument.
				 *
				 * The WP_Image_Editor::set_quality() method has priority over the filter.
				 *
				 * The filter is evaluated under two contexts: 'image_resize', and 'edit_image',
				 * (when a JPEG image is saved to file).
				 *
				 * @since 2.5.0
				 *
				 * @param int    $quality Quality level between 0 (low) and 100 (high) of the JPEG.
				 * @param string $context Context of the filter.
