我一直将我的 Discourse 用作可定制的 Evernote 替代品，但我非常怀念的一个功能是图像标注。这个 Discourse 主题组件将 Marker.js 添加到您的话题预览器中，使得每当您点击一张图片时，就会激活“标注模式”，允许您：
由于您是从预览器将图像复制回编辑器，它会自动像其他复制/粘贴的图像一样上传编辑后的图像！
目前还没有任何优化，它基本上只是 Marker.js 仓库 的打包副本。可能会存在错误，我仍在评估不同的标注库，但这只是一个抢先预览！
我仍在进行实验，因此目前请确保使用 discourse 分支，因为主分支是主要源代码所在（我会很快修复这一点）：
Wow, that looks incredibly useful - I could imagine it has more uses than simply annotating (memes 
). Excellent, I’m super proud and impressed of the continuous stream of talent and innovation that’s coming from the Discourse community! 
As if you brought MS Paint into Discourse 
This looks really good.
Very cool! can this be done without the cut-paste step at the end? Just trigger the upload direct once editing is done?
Yeah, this is the only hindrance I see.
Sounds awesome! This is going to be added to our forum soon! I think it might be cool if you can crop images. Anyways, great job @labofoz! Though, I do understand this is a theme component for annotating.
That’s a great point! I think it’s definitely possible but I think I’m going to do a more complete discourse integrated one from scratch over the weekend. I have a few other components I’m working on and I’d like to just reuse the dependencies Discourse already has.
The more I experiment the more I think I can get this down to just a few Kb vs 42, and with better integration and mobile support!
That’s a great point and definitely on my mind, I wanted to drag and drop collages together on the go so I’ll give this a try over the weekend too!
Incredible. Love it!
Very cool! I would love to use this, it has a lot of glitches but I’ll hold back feedback if you’re going to re-write it from scratch. Would love to see cropping as well. Looking forward to see where this goes 
Thanks! I released this a bit early to collect feedback ahead of time so feel free to list anything you find
Cropping is a great suggestion (especially for mobile users), so I’ve added that to my todo! I should have the first production ready version by eod Sunday. I’m just planning everything out now because I’d like it to be super simple for end users to use (like it’s not even there)
It’s just a bit clunky right now, like the toolbar doesn’t always show up, the annotations move when you scroll, sometimes a new annotation doesn’t appear in the visible window and you have scroll down or make the composer bigger to find it. The finish checkbox does nothing for me, so the copy/paste functionality doesn’t work. If you close the composer window the annotation still stays until you X out of the annotation bar.
Thanks that’s good feedback, I’m just going to do it from scratch as it would be less work for me than debugging it. There’s definitely some interest so I’ll work on a new version with everyone’s feedback over the weekend!
Hi! Nice plugin!
But it’s not working on our community 
Console reports this:
/theme-javascripts/03bd904a31a109db9cd635a25a5c572d54442e65.js?__ws=community.kodular.io:2 Uncaught DOMException: Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported.
at Image.a.onload (https://community.kodular.io/theme-javascripts/03bd904a31a109db9cd635a25a5c572d54442e65.js?__ws=community.kodular.io:2:3725)
Any idea what can be causing this?
Hi, thanks for reporting this! From that alone I wouldn’t be able to tell, but I should have the newer version out either tonight or tomorrow (probably tomorrow)
I mostly made this for myself using off the shelf tools just to see if the idea would work out, so I didn’t test this too much. I’ll post back when I have the update (which will probably be quicker to fix anyways )
Hey everyone, I’m still working on this but I’ve been trying to find a job too so I’m a little behind. I ended up learning the Discourse API and moved everything into a modal so that it’ll work on mobile devices too, is compatible with whatever theme you already have, and should be future compatible with Discourse.
I’ve also made progress on autosaving, which you can see in this video. The project will also be less than 5kb (since it uses Discourse’s core dependencies) and I’m trying to learn best practices, so you’ll have plugin hooks etc if you’d like to extend the annotator.
I should have this ready for sure by Sunday, but just wanted to give a quick update!
Hi @labofoz, has there been any updates on this? It seems that your github link is broken, and I couldn’t find your username there, either.
Temporary moved to the #theme:broken-theme category until the component is fixed.
I loved this theme, and I want to keep using it. @labofoz can you update the link or was the repository removed?
很希望能看到这个项目重获新生！
这个功能太棒了
