to_svg_string_base64()的代码也没几行,详情可在项目代码库中查看,基本原理就是生成上述XML格式的数据,并调用'base64:encode'函数把它变成一串在小程序中可用的数据。SVG原始数据,例如是这样: <svg xmlns="http://www.w3.org/2000/svg" version="1.1" viewBox="0 0 38 38" stroke="none"> <rect widt...
img.Href.BaseVal = "data:image/png;charset=utf-8;base64," + Convert.ToBase64String(bytes); // Add the image element into the SVG document document.RootElement.AppendChild(img); // Save the SVG document document.Save(@"C:\Files\image-base64.svg"); C# 中的 PNG 到 Base64 同样,我们...
Just use theConvert.ToBase64String methodthat takes a byte[]. For example: Refer this
The serialized string looks like this : <svg xmlns="http://www.w3.org/2000/svg"class="bi flex-shrink-0 me-2 green-check"width="24"height="24"role="img"aria-label="moon"><pathd="M437.019 74.981C388.668 26.629 324.38.001 256 .001S123.332 26.629 74.98 74.981C26.629 123.333 0 187.621...

str_index(string, substring): 返回$substring在$string中第一个位置; str_slice(string, start_at, end_at = nil): 返回从字符$string中第$start_at开始到$end_at结束的一个新字符串。 前人已有总结,可前往https://github.com/leeenx/sass-svg/blob/master/sass-encodeuri.scss查看完整代码。

If Base64 SVG images were supported (as requested here) would the process be the same but step 3 become "convert svg string to base 64 svg image"? or is there a better way to get the svg in the first place? Maybe a section in the readme pointing people in the right direction for...
