View thumbnail of SVG in documentlibrary?

Whenever a folder containing SVG-files is viewed in the Document Library Alfresco throws an error claiming that svg to png conversion is not supported:11:38:54,849 ERROR [org.alfresco.web.scripts.AbstractRuntime] Exception from executeScript - redirecting to status template error: 09290027 Wrapped E

Looks like Alfresco explicitly do not support the transformation in org.alfresco.repo.content.transform.magick.AbstractImageMagickContentTransformer. If you can get it to work, you are going to have to override the method and provide your own transformer implementation.

    /**
     * Some image formats are not supported by ImageMagick, or at least appear not to work.
     * 
     * @param mimetype the mimetype to check
     * @return Returns true if ImageMagic can handle the given image format
     */
    public static boolean isSupported(String mimetype)
    {
        if (!mimetype.startsWith(MIMETYPE_IMAGE_PREFIX))
        {
            return false;   // not an image
        }
        else if (mimetype.equals(MimetypeMap.MIMETYPE_IMAGE_RGB))
        {
            return false;   // rgb extension doesn't work
        }
        else if (mimetype.equals(MimetypeMap.MIMETYPE_IMAGE_SVG))
        {
            return false;   // svg extension doesn't work
        }
        else
        {
            return true;
        }
    }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Thanks for that, I guess it's not as easy as I had hoped then.

It seems a bit odd though that Alfresco can't handle this in a better way than throwing an exception every time the situation occurs.

Although this is an old thread,

Try this module http://code.google.com/p/alfresco-svg/ . It has thumbnailing, preview and indexing support

Performance could be tweaked, because thumbnails are generated for all definitions
