SVG Template​

Depending on configuration, this add-on requires webserver URL rewrite support!

Allows SVG (Scalable Vector Graphics) images to be stored as templates. This creates a new svg.php file in the XF root directory.

To generate a link to an SVG template (The template must have .svg at the end of the name!) ;

Code:
{{ getSvgUrl('tempate.svg') }}
Under Board information, if "Use Full Friendly URLs" (useFriendlyUrls) is set the URL generated is:
Code:
/data/svg/<style_id>/<langauge_id>/<style_last_modified>/<templateName.svg>
Otherwise
Code:
svg.php?svg=<templateName>&s=<style_id>&l=<langauge_id>&d=<style_last_modified>

Render to PNG​

Rendering SVGs to PNGs requires external support, and depending on OS this may result in odd limitations or poor rendering.

php-imagick support​

It is not recommended to use Imagick if it can be helped!

Ubuntu (using https://launchpad.net/~ondrej/+archive/ubuntu/php PPA);
Code:
Code:
sudo apt install php7.4-imagick libmagickcore-6.q16-3-extra
sudo systemctl restart php7.4-fpm

Note; some distro's require libmagickcore-6.q16-3-extra to be installed to enable SVG support.

Older versions of Imagick have poor SVG support, on top of Imagick's poor security reputation.

CLI support​

This is a generic escape hatch to plug in arbitrary png conversion, using proc_open in php.

Configure Render using proc_open option with;
<CLI-binary> {destFile} {sourceFile}

{sourceFile} is the source SVG written as a temp file {destFile} is the destination PNG file as a temp file

Alternatively input/output can be done via pipes

Note; template names are only alpha-numeric strings, which is enforced by validation before the CLI option is called

resvg CLI support​

Example using resvg, configure CLI command with;
Code:
/usr/local/bin/resvg --quiet {sourceFile} {destFile}

Precompiled binary​

Pre-compiled linux x86_64 binary has been made available here. Compiled on CentOS 7, works on Ubuntu 18.04/20.04

Compiling​

Compiling may bind to newer versions of glibc which can cause portability issues

Code:
curl https://sh.rustup.rs -sSf | sh
source $HOME/.cargo/env
cargo install resvg
cp ~/.cargo/bin/resvg /usr/local/bin/resvg
chmod +x /usr/local/bin/resvg

Inkscape CLI support​

Note; use snap as otherwise it is likely to have too old an instance!

Code:
sudo snap install inkscape
Configure CLI PIPE command with;

Code:
inkscape --export-type=png -p

Features​

Conditional rendering SVGs to PNG (for CSS/LESS)​

An example of conditional CSS to use the png over the svg for mobile clients
Less:
Code:
.mod_interrupt--svg.mod_interrupt
{
&--stop
{
&:before
{
content: url({{ getSvgUrl('sv_bbcode_modinterrupt_stop.svg') }}) !important;
}
<xf:if is="$xf.svg.as.png">
        .is-tablet &:before,
        .is-mobile &:before
{
content: url({{ getSvgUrlAs('sv_bbcode_modinterrupt_stop.svg', 'png') }}) !important;
}
</xf:if>
}
}

Explicit usage in templates;

Code:
<xf:if is="$xf.svg.enabled">
<xf:if is="$xf.svg.as.png and $xf.mobileDetect and $xf.mobileDetect.isMobile()">
<img src="{{ getSvgUrlAs('example.svg', 'png') }}"/>
<xf:else />
<img src="{{ getSvgUrlAs('example.svg', 'svg') }}"/>
</xf:if>
<xf:else />
<i class="fa fa-stop" />
</xf:if>

XenForo 2 routing integration​

While webserver rewrite rules are recommended, this add-on supports extending XenForo's routing system to provide zero-configuration support for SVG Templates

Nginx URL rewrite config​


Code:
location ^~ /data/svg/ {
   access_log off;
   rewrite ^/data/svg/([^/]+)/([^/]+)/([^/]+)/([^\.]+\..*)$ /svg.php?svg=$4&s=$1&l=$2&d=$3$args last;
   return 403;
}

Apache URL rewrite config​

Add the rule before the final index.php;
Code:
    RewriteRule ^data/svg/([^/]+)/([^/]+)/([^/]+)/([^\.]+\..*)$ svg.php?svg=$4&s=$1&l=$2&d=$3 [B,NC,L,QSA]

ie, should look similar to;

Code:
    #    If you are having problems with the rewrite rules, remove the "#" from the
    #    line that begins "RewriteBase" below. You will also have to change the path
    #    of the rewrite to reflect the path to your XenForo installation.
    #RewriteBase /xenforo
    RewriteCond %{REQUEST_FILENAME} -f [OR]
    RewriteCond %{REQUEST_FILENAME} -l [OR]
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^.*$ - [NC,L]
    RewriteRule ^(data/|js/|styles/|install/|favicon\.ico|crossdomain\.xml|robots\.txt) - [NC,L]
    RewriteRule ^data/svg/([^/]+)/([^/]+)/([^/]+)/([^\.]+\..*)$ svg.php?svg=$4&s=$1&l=$2&d=$3 [B,NC,L,QSA]
    RewriteRule ^.*$ index.php [NC,L]
