Hi,

I'm upgrading to version 26.1 of the Oxygen Web Author Component and have noticed that SVG images are not displaying in the editor.
I installed the `web-author-svg-plugin` and I also tried to install the `web-author-imageio-plugin` but that didn't help.

What am I missing? I didn't have any problems rendering SVG in version 21.

Here is the debug log:

Code: Select all

Hello,

We noticed in the log that the image URL includes query parameters like sourceDocPath=concept_test_1.dita and destDocPath=test.svg. These look like they might come from a custom implementation or customization. Could you please confirm if these parameters are part of your integration or plugin?

Hi,

Yes, it's part of the custom implementation.
I use the same approach for all images and have no problems with PNG, in my test cases only with SVG.
I have already tested on the server side, if I receive and send the result, everything works.

And just FYI I'm using the `ro.sync.ecss.extensions.api.StylesFilter` implementation to update the styles.

Code: Select all

styles.setProperty(Styles.KEY_MIXED_CONTENT, new StaticContent[]{new URIContent(requestUrl, builder.toString())});

Hello,

Thank you for your reply.

Could you please confirm what Content-Type is set on the server response for the SVG files?
Also, could you share a bit more about the architecture for handling SVGs in this context?

You can share these details via email at support@oxygenxml.com.

Best,
Cosmin

Hi,

Yes, the Content-Type header was not set. I added it, and now it's working.

Thanks for your help!

Best,
