I honestly don’t know if this is a “good idea”, but it solves this particular problem. My reasoning goes like this:
- The GIF isn’t very big, dimensions-wise
- Scaling up the image takes work
- Applying the filter takes work proportional to the number of pixels
- Why not apply the filter first?
He applied the blur first, then scaled up the image using a CSS transform. Neat hack.
