将Base64作为图像发送到Mobile Share

Question

Base64 data in IMG tag

(def zipper
  (z/vector-zip [:top
                 [:arbitrary 1 2
                  [:nesting 2 3 [:needle]]]]))

(splice-replace zipper {[:needle] [[:n1] [:n2] [:n3]]})
 => [:top [:arbitrary 1 2 [:nesting 2 3 [:n1] [:n2] [:n3]]]]

(splice-replace zipper {[:nesting 2 3 [:needle]] (range 3 10)})
=> [:top [:arbitrary 1 2 3 4 5 6 7 8 9]]

此javascript代码发送base64数据字符串。相反，我希望将此base64转换为图像，然后将其发送到Android共享菜单上的任何应用程序。

如何将base64字符串转换为图像并将其发送到共享菜单？
