stitchTiles
The stitchTiles attribute defines how the Perlin Noise tiles behave at the border.
You can use this attribute with the following SVG elements:
Example
html
<svg viewBox="0 0 420 200" xmlns="http://www.w3.org/2000/svg">
<filter id="noise1" x="0" y="0" width="100%" height="100%">
<feTurbulence baseFrequency="0.025" stitchTiles="noStitch" />
</filter>
<filter id="noise2" x="0" y="0" width="100%" height="100%">
<feTurbulence baseFrequency="0.025" stitchTiles="stitch" />
</filter>
<rect x="0" y="0" width="100" height="100" style="filter: url(#noise1);" />
<rect

<rect

Usage notes
| Value | noStitch | stitch |
|---|---|
| Default value | noStitch |
| Animatable | Yes |
noStitch-
This value indicates that no attempt is made to achieve smooth transitions at the border of tiles which contain a turbulence function. Sometimes the result will show clear discontinuities at the tile borders.
stitch-
This value indicates that the user agent will automatically adjust the x and y values of the base frequency such that the
<feTurbulence>node's width and height (i.e., the width and height of the current subregion) contain an integral number of the tile width and height for the first octave.
