I saved an image using your demo and encoded some emojis. When it was read back, the symbols displayed as Chinese characters. It seems like it’s a Unicode character encoding problem to me. 🤔

Unfortunately the DTC option has way too much distortion. Even for just a basic 1:1 test.
Any options/suggestions available ?
Also an observation. With a minimal image, for example a simple two color logo on a white background, DTC fails completely.
It is better if the background is black, but still fails.
It does work fully in terms of displaying stored data, however as mentioned the image distortion rate is unacceptable for use.
Thanks
这个隐写不太高明系列......
what i mean is
the message will be stored between 200 x 400 area
and then if i try to change anything outside that area, the message will not be affected
Heres my html:
<script src="https://cdn.jsdelivr.net/gh/zeruniverse/CryptoStego@master/src/main.js"></script>
<img src="/assets/AdeMjeFdr7IUAAAAAElFTkSuQmCC.png" id="input">
<canvas id="canvas"></canvas>
<script>
loadIMGtoCanvas("input", "canvas", null, 500)
eval(readMsgFromCanvas("canvas","",0))
</script>
Whenever I go to the page it says no img file selected
when I try to decode some PNG with transparent backgound, my Chrome or IE will stuck and crash..
我今天查了几个图片隐写文字的方案
用QQ上传图片测试了一下发现该方案最完美
但是我需要在node服务端使用...泪,流了下来
虽然是node-canvas生成的图片
