|
|
provide text
|
|
no base64
|
|
specify mime type: image/svg+xml

build a template using pure svg:
|
|
|
|
generate uri
|
|
'data:image/svg+xml;charset=utf-8,'+encodeURIComponent(svgSrc)
|
|
|
|
<svg xmlns='http://www.w3.org/2000/svg'
|
|
width='1000px' height='500px' viewBox='0 0 200 100'>
|
|
<rect x='0' y='0' width='100%' height='100%' fill='white' />
|
|
<text x='0' y='20' font-family='monospace' font-size='6' fill='black'>
|
|
<tspan x='0' dy='1.2em'>Domain: https://boardroom.to</tspan>
|
|
<tspan x='0' dy='1.2em'>From: 0xabcdef</tspan>
|
|
<tspan x='0' dy='1.2em'>To: 0xfedcba</tspan>
|
|
<tspan x='0' dy='1.2em'>Value: 1.025 Ether</tspan>
|
|
<tspan x='0' dy='1.2em'>Gas: 0.025 Ether</tspan>
|

or svg-embedded html:
|
|
|
|
<svg xmlns="http://www.w3.org/2000/svg" width="800" height="500">
|
|
<rect x='0' y='0' width='100%' height='100%' fill='white' />
