Item13895: rest/ImagePlugin/resize returns corrupt data

SolrPlugin includes nice image preview on the result page.

The images get fetched via /bin/rest/ImagePlugin/resize?.....

In Foswiki 2.0.3, ISO Store, we observer now, that the jpg previews data gets wrongly utf encoded.

I don't know, whether this is a bug of the Plugin or a shortcoming of the Rest API in core.

It's a bug in the plugin. binary data should be output using response->body() text with response->print() Thanks CDot for the reminder. Try the following patch (not tested)

   }
 
   return;

MichaelDaum, can you review this. Plugin is CoordinateWithAuthor See TestItem13895 for a demonstration.

Thanks for the patch. I will add it to the next release. I didn't realize the error before as I use XSendFileContrib to deliver attachments and thumbnails for better performance.

Yeah, patch works fine.
