Render Stl Png

Convert SVG to PNG or JPG for quick sharing (e.g. Telegram) or print.

Create SVG images and convert them to PNG without external graphics libraries. Use when you need to generate custom illustrations, avatars, or artwork (e.g., "draw a dragon", "create an avatar", "make a logo") or convert SVG files to PNG format. This skill works by writing SVG text directly (no PIL/ImageMagick required) and uses system rsvg-convert for PNG conversion.

Turn a source image (or multi-color mask image) into a 3D-printable bas-relief STL by mapping colors (or grayscale) to heights. Use when you have an image from an image-gen skill (nano-banana-pro, etc.) and want a real, printable model (STL) via a deterministic pipeline.

Generate high-quality 3D ball-and-stick molecular renderings from SMILES strings or PDB structures using POV-Ray ray tracing.

Convert HTML+CSS into PNG images via Chrome headless for accurate text layouts like covers, posters, and info cards at zero API cost.

Decode and embed Stegstr payloads in PNG images. Use when the user needs to extract hidden Nostr data from a Stegstr image, encode a payload into a cover PNG, or work with steganographic social networking (Nostr-in-images). Supports CLI (stegstr-cli decode, detect, embed, post) for scripts and AI agents.
