Format
filter(type="drop_shadow", ...)
Args
x: Shadow horizontal offset (defaults to 1)y: Shadow horizontal offset (defaults to -1)size: Blur amount (defaults to 1; negative values create inset shadows)offset: Size increase before blur (defaults to 0)color: Shadow color (defaults to 50% transparent black)
Applies a drop shadow to this image. This is a combination of multiple filters, since it will apply an outline if offset is included, a Gaussian blur to the shadow, and will underlay the shadow beneath the image.
You can also think of this filter as an outer glow.
If you use a size less than 0, the shadow will appear inside the image instead. This would be an inset shadow, or inner glow.
