我目前正在开发一个项目，该项目要求我将 Topaz 签名图像嵌入到 HTML 页面中。我知道如果图像已更改为 Base64 字符串，但签名返回的字符串值是“ASCII 十六进制字符串”，则这是可能的。有人有可以显示嵌入的“ASCII 十六进制字符串”的代码吗？谢谢。
下面是我发现的一个示例字符串，它将在页面中嵌入一个红点，并且效果完美。

下面是从签名板返回的字符串。 （抱歉，它真的很长。）

只是想让大家知道 Topaz sig 字符串是一种专有格式，而不是图像。您需要做的就是将 sig 字符串存储在某个地方。然后，当您稍后想要显示签名时，只需在要显示它的页面上创建一个 ActiveX 对象，然后将 sig 字符串设置为存储的值即可。
这是我写的HTML页面。希望它可以帮助下一个人寻找同样的东西。 :)
另外提醒一下，这是一个 ActiveX，因此它只能在 IE 中运行。
