I have a template for making thumbnails out of different formats:
“thumb”: { “use”: “:original”, “robot”: “/image/resize”, “format”: “png”, “background”: “none”, “resize_strategy”: “pad”, “zoom”: false, “width”: 80, “height”: 80
}
Problem: If i test-it with vector files (eps, svg) the background is white. The vector contains only the art, no background.
If i test-it with .psd file, the result background is transparent.
I attached the test files.
