Hi I am really new to SVG's and creating assets using SVG's. This is my first attempt and what I have is a rounded rectangle with a gif of water as the background. I was wondering how to modify this code in order to make it not have those gaps.
<svg id="water" width="440" height="440">
<defs>
<pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
<image xlink:href="https://i.imgur.com/u7ufQto.gif" x="0" y="0" width="100" height="100" />
</pattern>
</defs>
<path d="M100,100 h200 a20,20 0 0 1 20,20 v200 a20,20 0 0 1 -20,20 h-200 a20,20 0 0 1 -20,-20 v-200 a20,20 0 0 1 20,-20 z" fill="url(#img1)" stroke="black" stroke-width="3" />
</svg>
