What is gmod-tinysvg?

tinysvg is a small library that lets Garry's Mod addons draw SVG images as real vector graphics instead of flat picture files. Normally, showing an icon at different sizes in a game means preparing several versions of the same image at different resolutions, since a regular PNG image gets blurry or blocky when scaled up. SVG images are different: they describe shapes with math instead of pixels, so they can be drawn crisply at any size, from a tiny 16 pixel icon up to a poster sized 2048 pixel version, using the same single file. This project is written entirely in Lua, the scripting language Garry's Mod addons are built in, and ships as one client side file with no outside dependencies. It works anywhere Garry's Mod normally lets you draw things on screen: heads up display overlays, VGUI panel interfaces, and 3D2D world drawing. For performance, tinysvg does not redraw the full vector shape every single frame. Instead, it renders the image once per size it is needed at and reuses that cached result, which keeps the cost low even when an icon is shown often. It also supports recoloring a white icon to any color and fading it in or out without needing to redraw it from scratch, and it comes with an IconSet helper for managing a whole set of named icons that need to load and fade in cleanly. The README lists broad support for common SVG features such as paths, basic shapes, transforms, gradients, and CSS style colors, while a few advanced features like embedded text, images, and filter effects are not supported and get skipped with a warning rather than causing an error. This tool is aimed specifically at people building addons or user interfaces for Garry's Mod who want sharp, resizable icons without maintaining separate image files for every size they need.
