How do I create transparent watermarks? 3.0 version

Hi Sir,
I use GroupDocs.Viewer.Examples.CSharp to add watermark on doc.
Does Watermark object support “Opacity” property?
Thanks.

Hi Ho,


Thank you for your query.

Currently GroupDocs.Viewer have no any option to set the transparency/opacity of the watermark. However, I am going to create a ticket of this new feature in our issue/task tracking system.


Many Thanks.

The issues you have found earlier (filed as VIEWERNET-475) have been fixed in this update.

You are welcome :)

Place this at the end of the page. This works for rendering files as HTML.


/* I think this is for 2.0 /
.html_watermark{
opacity: 0.<>;
filter: .<>;
}
/ This should work for 3.0*/
.doc-page-watermark{
opacity: 0.<>;
filter: .<>;
}
Does not seem to work for image renderings though…

Hi R darling,


Thank you for your suggestion.

Infact, css/stylesheet is relevant to the front-end and it applies after rendering. As the matter of fact, the css/styles can only be applied on the HTML. It cannot take any effect inside the image body.
Hence, the rendering is the back-end operation, that’s why no post rendering measures would take effects on image based rendering.

Note: Your raised issue is already under the product team’s process.

Please stay tuned!
