OK. Totally understand that.
Just to clarify my problem for the record:
On my pages, I have Images and SVG mixed to visualize projects. Photographic images are jpg or png and SVG for path visuals, like font-images or illustrations.
For the thumbs, I am choosing the images, that would give a basic idea of the Project. That could also be an SVG. I want the thumbs to be squared, so I crop them 200 by 200.
That is not working for SVG. So it actually would not be about resize the svg – it would be more about cutting it into the right ratio – the pixels doesn’t realy matter here for me.
But I see that is not how it works here.
So I guess I have to prepare the images for that before uploading.
Thanks for your answers!
