Want to to do we have any plan to support vector images?
For example, emf, svg, wmf and eps.

Currently when preview emf, it shows like:

Additional Information
I'm not fammilar with development of windows appliction. But I tried to search related posts on Google (Hope these will be useful):
For emf and wmf:
How to: Load and Display Metafiles
For svg:
SVG.NET

1. NConvert (used for image preview now) does support eps, emf, wmf...
   https://www.xnview.com/en/nconvert/#formats
2. There has a GFL sdk also supports these formats.
   https://www.xnview.com/en/GFL/index.php
   Moreover, found a c# wrapper for this sdk: https://newsgroup.xnview.com/viewtopic.php?f=4&t=33986&sid=62e852aa1f50633c2845221050ce4eaa
3. Actually, GFLSDK, Nconvert, XnView, ... use same library.

For .ai, I am afraid the link you provided is a plugin for Adobe Illustrator, it just allows Adobe Illustrator to save a file into .xaml.

For .eps, it can be converted into PDF first.

Let me test NConvert for emf and wmf.

Any status update on this?

I would like to have previews of EPS files too. SVG and the other vector formats would be even nice. Thanks a lot for considering to integrate it.

@xupefei did you get to try emf files with nconvert? I don't know if my thinking is too narrow here but if formats are supported by NConvert (see NConvert/docs/Formats.txt) shouldn't it be possible to just add them to the format-list in QuickLook.Plugin.ImageViewer/Plugin.cs?
Here is a sample file if you need one, rename it to .emf first

@xupefei may I remind you of my last unanswered question?

[xupefei]

Sorry for not answering your question.

I just switched the ImageViewer from NConvert to ImageMagick in the latest Nightly. ImageMagic might be able to handle all formats the OP mentioned (haven't tried).

Yes, just add it to the format list is enough.

No problem, thx for replying now ;)
Maybe to be of some form of help, I looked up which of the requested formats are supported by imagemagick und what notes they mention on https://imagemagick.org/script/formats.php

file extension	notes from imagemagick
emf	Only available under Microsoft Windows. Use -size command line option to specify the maximum width and height.
eps	Requires Ghostscript to read
wmf	Requires libwmf. By default, renders WMF files using the dimensions specified by the metafile header. Use the -density option to adjust the output resolution, and thereby adjust the output size. The default output resolution is 72DPI so -density 144 results in an image twice as large as the default. Use -background color to specify the WMF background color (default white) or -texture filename to specify a background texture image.

EPS plugin is now available: https://github.com/QL-Win/QuickLook/wiki/Available-Plugins

Enjoy :)
