Add new logo to the project

[raghu-kamath]

This Pull Request intends to add a new word-mark for the project.

The logotype includes the alphabet 'Q' written in Morse code, this was inspired by the use of morse code in the logotype of a downstream project - Kaidan. The logotype loosely resembles a chat speech bubble, hinting that this library is used to facilitate chat communication. The morse code enclosed within the curly braces which tries to denote that this is a library meant to be used for making applications

I have included the light and dark version of the logo and also the source svg.

Adding the logo here for the conversation

Thanks for opening the PR :) The logo looks great! Could you please make sure that the graphics are optimized?

[raghu-kamath]

@melvo I optimised the svg files and also split them into two separate dark and light themed versions. The png files are already optimised.

[melvo]

It seems that the PNG files are not as optimized as they would be if you used https://invent.kde.org/network/kaidan/-/wikis/optimizing-graphics#portable-network-graphics-png . Could you please try that again?

[melvo]

I suggest to use the term logo instead of word mark and remove the prefix qxmpp- from the filenames.

[raghu-kamath]

Okay I will make those changes.

[raghu-kamath]

Hi @melvo 👋🏽

I optimised the png according to the instructions

I also changed the name of the files according to your suggestion.

[melvo]

That looks perfect! Could you also add the line

<schema:logo rdf:resource='https://raw.githubusercontent.com/qxmpp-project/qxmpp/master/assets/logo-light.svg'/>

after https://github.com/qxmpp-project/qxmpp/blob/master/doc/doap.xml#L26? That would make it possible for https://xmpp.org/software/libraries/qxmpp/ to display the new logo.

[melvo]

Please also add .license files (similar to https://invent.kde.org/melvo/xmpp-providers/-/blob/master/badge.svg.license or https://invent.kde.org/websites/kaidan-im/-/blob/master/images/contributing.svg.license, depending on the license you would like to use) for each new file.

@lnjX What would be your preferred license for the logo?

@lnjX What would be your preferred license for the logo?

I think the logo should be trademarked so that other projects don't misuse it. And it can be kept in a cc-by-sa license so that people can share and use it.

But this is just my opinion please let me know which license to add I will add it.

[lnjX]

I prefer CC BY-SA 4.0

[melvo]

We could also add the theme-specific colors to the SVG as it is done in https://github.com/xsf/xmpp.org/commit/c00e41c286d3ed820dc1dfdaf6d5cf569eb3baeb for the XMPP logo of https://xmpp.org.

@raghu-kamath @lnjX What do you think about it?

[raghu-kamath]

I think it makes sense and will not need the png files. do all the places where this will be shown will have support for svg? That would also make it easy to embed in the https://xmpp.org/software/libraries/qxmpp/ page

We do have a green colour so we need to style the curly braces selectively.

[raghu-kamath]

I removed all the complexities of multiple images and svg files. Now it is only one svg and there is a css style inside the svg which will make it switch to light and dark. We can use this logo multiple places like the https://xmpp.org/software/libraries/qxmpp/ page and it will also adapt to light and dark mode on that site too if the same sgv is linked.

[melvo]

@raghu-kamath It looks fine! Could you also optimize the SVG again and remove empty spaces and line breaks?

[melvo]

If you are done, you can squash all commits and use a commit message like Add new QXmpp logo.

[raghu-kamath]

@lnjX @melvo Is there any other feedback on this PR?

[melvo]

@raghu-kamath I am fine with the current state. @lnjX has to review and accept it now.
