The patternTransform read-only property of the SVGPatternElement interface reflects the patternTransform attribute of the given <pattern> element. This property holds the transformation applied to the pattern itself, allowing for operations like translate, rotate, scale, and skew.
An SVGAnimatedTransformList object.
In this example, the pattern is rotated by 20 degrees, skewed on the X-axis by 30 degrees, and scaled by a factor of 1 horizontally and 0.5 vertically:
<svg viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg">
<!-- Apply a transform on the tile -->
<pattern
id="p1"
width=".25"
height=".25"
patternTransform="rotate(20)
skewX(30)
scale(1 0.5)">
<circle cx="10" cy="10" r="10" />
</pattern>
<!-- Apply the transformed pattern tile -->
<rect x="10" y="10" width="80" height="80" fill="url(#p1)" />
</svg>
