How to Resize an Image for a Circular SVG Mask Fit?

Resizing an Image to Fit a Circular SVG Path

When attempting to cut a circular part from an image using an SVG path, it's important to ensure proper alignment. If the image doesn't fit well, it might be due to incorrect sizing or positioning of the SVG mask.

Here's an alternative approach to achieve the desired result:

Enhancement Using an SVG Mask:

This method employs an SVG mask to create a circular hole within which the image is displayed:

<code class="svg"><svg width="200" height="200">
  <defs>
    <mask id="hole">
      <circle r="100" cx="100" cy="100" fill="white"/>
      <circle r="50" cx="180" cy="180" fill="black"/>
    </mask>
    <pattern id="img" patternUnits="userSpaceOnUse" width="200" height="200">
      <image xlink:href="https://picsum.photos/200/200?image=1069" x="0" y="0" width="200" height="200" />
    </pattern>
  </defs>
  <!-- Create a rect, fill it with the image and apply the mask -->
  <rect fill="url(#img)" width="100%" height="100%" mask="url(#hole)" />
</svg></code>

Explanation:

• #hole: This defines the SVG mask containing two circles, one white and one black. The white circle represents the area to be displayed, while the black circle creates a mask to hide the area outside the circle.
• #img: The SVG pattern defines a pattern using an image. The patternUnits="userSpaceOnUse" attribute ensures the pattern stretches to fit the shape it's applied to.
• The rect element fills the entire SVG container with the #img pattern and applies the #hole mask to reveal the circular cutout.

Using this enhanced approach, the image should now fit properly within the circular SVG mask.
