Dear William,<br class="">
<br class="">
Thank you for investigating the color inversion. We have checked the
results from using the code you suggest and they look fine.<br class="">
It would be very nice to have this switch implemented in the OMERO
API.<br class="">
<br class="">
Best regards,<br class="">
Andrii<br class="">

<div class="">Dear OMERO developers,<br class="">
<br class="">
We are interested in reversing the color scheme of images
as sometimes users deposit to us images with a negative
contrast. The inversion can be done client-side, however
the browser support of the CSS implementation is lacking
and the Javascript solution is not feasible due to CORS
restrictions. The optimal way would be to do this
server-side. Please could you tell if it would be possible
for you to implement the reversion of colors in Webgateway
views render_image and render_image_region? Perhaps as a
switch that can be set in the call to server that would
invert the colors of the resulting image?<br class="">
<br class="">
Many thanks and best regards,<br class="">
Andrii<br class="">
