base30显示问题 about jsignature HOT 7 OPEN

另外js通过base30转base64可有示例代码？在demo中没有找到。应该怎么调用？能否写个示例

Sorry, theres no sample code to convert between base30 to base64. You might need to look at another library to this. It sounds to me like you are trying to insert a base30 into a canvas that is 1/10 the size of the canvas 1. Have you thought of exporting to svg then instead of loading the signature into canvas 2, just display the svg?

我也希望导出的是svg，但是后台返回的数据是一串base30的字符，除了用canvas显示，没有其他的办法了。img标签也无法显示base30的图案，而这个base30是在300x600的canvas上绘制生成的，我需要展示的时候缩小到30x60，并且旋转90deg成60*30显示

Did you try using
jSignature("getData", "svgbase64")

from jsignature.

我无法使用jSignature("getData", "svgbase64")
后端sql保存的是一串base30的字符串，
前端请求后端是得到一串base30字符串，需要显示出该base30字符串的图案。

from jsignature.

If you cannot save svgbase64 in your sql db when exporting the signature then you will need to either convert the base30 to another format with a backend process or look at some other libraries to convert.

后端不同意将base30转换为另一种格式，后端明确要求只保存base30字符串在sql中，并且要求前端展示base30字符串对应的图片。
