Generating Long Event Images for QQ Music Albums: Front‑end and Server‑side Solutions, Pitfalls and Optimizations

To quickly create shareable long‑event images for QQ Music albums, the team evaluated client‑side DOM‑to‑image tools (html2canvas and SVG) that suffered from blur, incompleteness, slow rendering and oversized base64 data, then migrated rendering to the server using PhantomJS, node‑canvas and ultimately ImageMagick, whose combined script execution, mpc caching, and Q8 build provided the most balanced quality‑performance solution despite remaining operational quirks.
