org-mode是否支持显示基于URL的inline images时改变图片大小

我知道在org-mode里显示存在本地的inline image时,可以如此控制图片大小:

#+attr_org: :height 50% :width 50%
[[./image.png]]

这样高度和宽度会显示为原图的50%。 但是基于URL的图片如此并无效果:

#+attr_org: :height 50% :width 50%
[[http://example.org/image.png]]

想问有无方法解决这个问题?搜了一圈问了几个朋友,没闻到。 要是org真的不支持,可以给org-mode贡献一下,或者写个小包了。

我这边 org-mode 不会内嵌显示网络图片(本地的没问题),是不是需要特殊的包或者配置?

org-mode原生支持显示网络图片啊,你的网络图片链接是怎么写的?

就把你写的 copy 过来,然后把 url 改成了 emacs-china 那个 logo。

我的就可以显示。你用的Emacs可能有点问题

GNU Emacs 28.0.50 (build 1, x86_64-apple-darwin20.6.0, NS appkit-2022.60 Version 11.5.2 (Build 20G95)) of 2021-09-19 也没法显示

@mkvoya @Voleking 不好意思,是我搞错了。

我运行emacs -Q,然后在org里放了图片的链接,的确无法显示。

我先调查一下是装了什么包让我的Emacs可以显示网络图片了。

@mkvoya @mkvoya 你们需要设置org-display-remote-inline-image'download或者'cache来显示基于网络链接的图片。这个变量的文档:

org-display-remote-inline-images is a variable defined in org.el.

你是用的 doom 吧?这个 org-display-remote-inline-images 曾经在 telegram 讨论过,是支持透过 tramp 来显示图片。

https://www.reddit.com/r/orgmode/comments/p4ii75/orgdisplayremoteinlineimages_is_not_working/

org-mode 9.4支持了这个特性,我可以显示remote inline image,问题是如何显示的时候resize一下

org 9.5 没办法复现啊

在打开这个 org 文件前已经设置 org-display-remote-inline-images'download
