<div>Thanks for your email.</div>
<div><br>
</div>
<div>I am not sure if I follow it correctly but as far as I can see<b> webgateway.views.render_image_region </b>already support quality.</div>

<div>Although it is true that quality is not taken to the account in webgateway_cache.</div>

<div>Thanks for letting us know. I have created ticket to fix webgateway_cache in https://trac.openmicroscopy.org/ome/ticket/13011</div>
