Why I built a pixel-perfect report engine with Rust and Skia

Introduction For many years, I have been working on business systems where report generation is a critical component. However, I repeatedly encountered the same problems: Layout differences depending on printer drivers OS-specific rendering inconsistencies Difficulty achieving true WYSIWYG output These issues are not new, but they are still not fully solved. The Problem In traditional report systems, rendering often depends on external components such as printer drivers or OS-level graphics APIs. This leads to: Slight layout shifts Inconsistent text measurement Different output between environments For business reports, even small differences can be unacceptable. The Approach To solve this, I designed a report engine with the following principles: Fully deterministic layout Pixel-perfect rendering No dependency on printer drivers Cross-platform consistency The engine directly controls rendering using Skia. Why Rust I chose Rust for: Memory safety Predictable performance Strong control
