SVG Filter Effects: Creating Advanced Visual Effects

The Power of SVG Filters

SVG filters enable sophisticated visual effects without raster images. From simple shadows to complex distortions, filters transform vector graphics in powerful ways.

Filter Basics

Filter Structure

Performance Considerations

Performance Impact

Filter Performance:
feGaussianBlur: Heavy (radius dependent)
feColorMatrix: Light
feTurbulence: Very heavy
feDisplacementMap: Heavy
Chained filters: Cumulative

Optimization Tips

CSS Filter Alternative

When possible, use CSS:

.blurred {
  filter: blur(5px);
}
.grayscale {
  filter: grayscale(100%);
}

Browser Compatibility

Fallback Strategies

.element {
  / Fallback /
  box-shadow: 0 2px 10px rgba(0,0,0,0.3);
}
@supports (filter: url(#shadow)) {
  .element {
    box-shadow: none;
    filter: url(#shadow);
  }
}

Conclusion

SVG filters enable sophisticated effects impossible with CSS alone. While computationally intensive, they offer precise control over visual treatments. Use them judiciously for impactful effects, always considering performance and providing fallbacks.
