License and Attribution of the LLVM Logo?

[hwhsu1231]

Hello, LLVM Team,

I’m the author of the localizethedocs organization, which focuses on creating localization projects for open-source project documentation. For example:

• localizethedocs/cmake-docs-l10n
• localizethedocs/conan-docs-l10n
• localizethedocs/ros2-docs-l10n
• and more.

Currently, the llvm-docs-l10n project is in the incubation phase. To place the LLVM logo at the top of the README, I need to upload the logo to the static repository and then access it via jsDelivr.

Although I haven’t been able to find the SVG version of the current LLVM logo in the LLVM repository or website, I found its SVG logo on a third-party site:

LLVM SVG and transparent PNG icons | TechIcons

Is this logo safe to use? Where can I download the official LLVM SVG logo? What is the license of the LLVM logo? What attribution is required?

I found its SVG logo on a third-party site:

That is a smaller version of the first one on The LLVM Compiler Infrastructure Project .

On that page there is:

Usage Rights of the Older Logo

(emphasis mine)

But it does not have similar text for the current logo.

Based on Newer LLVM Logo origins , maybe @bwatson can help.

(also would be good to update that page)

@bwatson Looking for your help!

I found that this SVG version of the logo requires a dark background. When I removed the background layer, the black outlines of the dragon disappeared. Would it be possible to get an SVG file that retains the dragon’s black outlines with a transparent background?

[bwatson]

Use of the logo can be obtained from the LLVM Foundation via email at board@llvm.org

SVGs can be programatically edited, if all the outline elements have the same value of some specific attribute we could change them that way?

(zero experience in doing this, but I looked in the file and I see structured text)

Edit: unless the problem is that there are only "out"lines on the inside, and it expects the background colour to provide the “outside” outlines.

The only other version we have is here: https://llvm.org/img/LLVMWyvernBig.png

Sorry, we don’t have another .SVG file!

Well, that’s weird. Theoretically, those PNG files are exported from the SVG file, but it looks like LLVMWyvernBig.png does have black outlines. How is it exported?

[MacDue]

Added an outline to the SVG, if that helps

Added an outline to the SVG, if that helps

@MacDue Perfection! That’s what I want!

@bwatson

You’re welcome to use the current logo as with the same licensing parameters as the rest of the LLVM Project (https://releases.llvm.org/14.0.0/LICENSE.TXT)

@bwatson Can I use this SVG version of the LLVM logo with the same license?

[bwatson]

hwhsu1231 It looks like I misspoke. Any use of the logo requires permission from the LLVM Foundation via email as board@llvm.org.

Updated previous message to reflect that.

Hello all. I wanted to clarify that the LLVM logo on our website did not clarify which license it is under. The LLVM Foundation is working to correct this error and provide guidance on when the logo can freely be used and what situations might require approval (if any). For this specific use case and in order to unblock you, please email board@llvm.org as Britton mentioned above.
