image_max_bit_depth │ filter-hook │ WP 6.8.0

Filters the maximum bit depth of resized images.

This filter only applies when resizing using the Imagick editor since GD does not support getting or setting bit depth.

Use this to adjust the maximum bit depth of resized images.

add_filter( 'image_max_bit_depth', 'wp_kama_image_max_bit_depth_filter', 10, 2 );
