LR 7: image and thumbnail not shown for SVG files

[Mirto Silvio Busico，修改在7 年前。]

I have some images uploaded in Documents and Media.
For jpg images I can see the image and the preview in Document and media and in an asset publisher.

For svg files (after I enabled the image type) I can do the upload but no image and no thumbnail are showed in document and media and in asset publisher.

Thumbnails are correctly created and if I use the function "Reset preview and thumbnail files for Documents and Media portlet." in Server administration, the thumbnail are cleared and recreated. So I think imagemagick is correctly configured.

What have I to do to have LR manage svg files?

I would like to know as well. Currently I am on 7.0GA3 and SVG Files will not work/show up as with the other formats.
Did you ever got a response or found a solution to this?
If so - please report back here.

Sorry. Still I didn't find a solution nor received a reply.
If I'll have news I'll post here

I don't know if it is useful for you, I modified Liferay 5.1.1 source code to support SVG. The version is not the same you are using, but it should be useful to take as example. The concept is that with svg the thumbnail (useless) is created as dummy image and in the view part the thumbnail is replaced with the image itself but with the thumbnail width and height.
Then the correct content-type must be image/svg+xml.
Attached the files for Liferay 5.1.1. The ROOT folder (for Liferay 5.1.1) must be copied in tomcat webapps folder. The zip includes source files and class files.

I will adapt that to Liferay 7.

Thanks I'll give it a try asap.

Well, it probably would be best if Liferay would just show the svg files and not do anything with svg. It actually makes no sense to create a thumbnail of an svg.

As a workaround, maybe you could add the TwelveMonkeys lib to Liferay:
https://github.com/haraldk/TwelveMonkeys

Liferay uses ImageIO to read and scale of images. It doesn't matter at all if you have configured ImageMagick or not. It simply isn't used by Liferay to create thumbnails or scale images. It can only handle image formats ImageIO supports. I guess, it comes down to this list:
https://docs.oracle.com/javase/7/docs/api/javax/imageio/package-summary.html

But TwelveMonkeys extends this functionality and maybe thumbnail creation works after installing this lib?
