I just joined this community and I might have some questions that could be considered too basic.
Recently, I've been trying to understand SVG and came across something that left me puzzled.
Take a look at this:
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="100px" height="100px">
<defs>
<radialGradient id="Gradient5" cx="0.5" cy="0.5" r="0.5" fx="0.13" fy="0.13">
<stop offset="0%" stop-color="red"/>
<stop offset="100%" stop-color="blue"/>
</radialGradient>
</defs>
<rect x="10" y="10" rx="15" ry="15" width="100" height="100" fill="url(#Gradient5)" stroke="black" stroke-width="2"/>
</svg>
What's with the top left corner in the image? I struggle with mathematical concepts and I sense that this issue is math-related. Can someone offer guidance?
