将文本嵌入PNG [英] Embed text into PNG

问题描述

我正在寻找一种工具，让我可以在PNG文件中嵌入json格式的信息。

I'm looking for a tool that'd let me embed json-formatted information inside a PNG -file.

到目前为止它已经非常安静了。我是否必须自己编写？

This far it's been quite quiet. Do I have to write it myself?

我对使用javascript做这件事特别感兴趣。我从画布中提取 toDataURL -method。

I'd be especially interested of doing it with javascript. Into an image I extract from a canvas with toDataURL -method.

推荐答案

如果您想嵌入文本，您可能需要查看此内容，其中来自 PNG 规范。这似乎有点复杂。

If you want to embed text you may want to look at this in particular, which comes from the PNG specification. It seems a little on the complicated side.

简单隐写方法看起来更简单。

The "easy" steganographic method looks a little more simple.

实际上更适合您的目的是创建一个包含图像数据和JSON数据 - 然后只需将对象传递到您需要的任何地方。

What may actually be better suited for your purpose is to create a javascript object that contains the image data and the JSON data - then just pass that object around wherever you need it.
