如何显示 json 编码的图像 - jquery signaturepad

Question

我正在尝试显示已编码的图像。看起来是这样的：

"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAOQAAAA3CAYAAAAc\/eYMAAAAuUlEQVR4nO3TMQEAMAyAsPo33Z6TMI5EAQ+zQMb8DgAeQ0KIISHEkBBiSAgxJIQYEkIMCSGGhBBDQoghIcSQEGJICDEkhBgSQgwJIYaEEENCiCEhxJAQYkgIMSSEGBJCDAkhhoQQQ0KIISHEkBBiSAgxJIQYEkIMCSGGhBBDQoghIcSQEGJICDEkhBgSQgwJIYaEEENCiCEhxJAQYkgIMSSEGBJCDAkhhoQQQ0KIISHEkBBiSAgxJIQclyE3fsX77n0AAAAASUVORK5CYII="}

我试过了：

base64-decode()

对于没有那部分的这个字符串：

data:image\/png;base64,

但没有结果。

我应该如何转换图像以显示它？谢谢。

已编辑：此图像实际上是签名。我正在使用 jquery 签名板。在数据库中看起来像这样：

name":"My Name","output":"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAOQAAAA3CAYAAAAc\/eYMAAAAuUlEQVR4nO3TMQEAMAyAsPo33Z6TMI5EAQ+zQMb8DgAeQ0KIISHEkBBiSAgxJIQYEkIMCSGGhBBDQoghIcSQEGJICDEkhBgSQgwJIYaEEENCiCEhxJAQYkgIMSSEGBJCDAkhhoQQQ0KIISHEkBBiSAgxJIQYEkIMCSGGhBBDQoghIcSQEGJICDEkhBgSQgwJIYaEEENCiCEhxJAQYkgIMSSEGBJCDAkhhoQQQ0KIISHEkBBiSAgxJIQclyE3fsX77n0AAAAASUVORK5CYII="

如何显示此签名？

刚刚经过编码的图像（将 /\ 替换为 /）在 img 标签中：

<img src="data:image/png;base64, iVBORw0KGgoAAAANSUhEUgAAAOQAAAA3CAYAAAAc/eYMAAAAuUlEQVR4nO3TMQEAMAyAsPo33Z6TMI5EAQ+zQMb8DgAeQ0KIISHEkBBiSAgxJIQYEkIMCSGGhBBDQoghIcSQEGJICDEkhBgSQgwJIYaEEENCiCEhxJAQYkgIMSSEGBJCDAkhhoQQQ0KIISHEkBBiSAgxJIQYEkIMCSGGhBBDQoghIcSQEGJICDEkhBgSQgwJIYaEEENCiCEhxJAQYkgIMSSEGBJCDAkhhoQQQ0KIISHEkBBiSAgxJIQclyE3fsX77n0AAAAASUVORK5CYII=">
