stitchTiles

The stitchTiles attribute defines how the Perlin Noise tiles behave at the border.

Only one element is using this attribute: <feTurbulence>

<svg viewBox="0 0 420 200" xmlns="http://www.w3.org/2000/svg">

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.
