Unmaintained - [Spolzer] Watermark

Compatible XF 2.x versions

The add-on applies watermarks to images uploaded by users to the forum. Two operating modes, flexible filters, and full control from the ACP.

Two operating modes

Dynamic — the watermark is applied on the fly on every view, and the original file is not touched. Change the settings and everything applies immediately, with no rebuild.

Permanent — the watermark is written directly into the file forever. Moreover, this happens right when the user uploads it — the file already reaches the server with the watermark. Disable the add-on and nothing changes; the watermark stays in the file.

What can be applied

Text — write anything you want. Supported variables:
{forum} — forum name
{username} — the name of the user who uploaded the attachment
{year} — year.
You can add your own variables directly in the settings.
Logo — upload an image (JPG, PNG, WebP), and it will be placed on top of the image with the required scale and transparency.

Appearance settings

Position — any corner or center
Watermark opacity
Offset from edges
For text: font, size, color, opacity, background color and opacity, background corner radius
For logo: scale as a percentage of the image width
Four built-in fonts — Free Sans, Free Serif, Free Mono, Noto Naskh Arabic. You can upload your own TTF or OTF.

Formats and sizes

JPG, PNG, WebP — through GD or Imagick, whichever is available on the server
Animated GIF — every frame is processed separately and the animation is preserved
WebP — with automatic fallback to PNG if the server does not support it
Minimum dimensions — you can specify a minimum width, height, or shortest side below which no watermark is applied

Filters — "who and where"

Content types — posts, profiles, XFRM resources, AMS articles, Media Gallery, News Publisher, Tickets, DragonByte eCommerce
Excluded forums — exclude a forum so no watermark is applied there
Excluded groups — you can exclude any user groups that should not receive a watermark
Bypass permission — through standard XenForo permissions for specific users or groups
