It provides a recursive stacking-box model to determine interface coordinates, serving as a lightweight solution for two-dimensional layout calculations in C99 or C++ environments. The engine distinguishes itself through its focus on portability and resource efficiency. It utilizes a dependency-free memory abstraction that allows developers to override default allocation and assertion routines, making it suitable for specialized or restricted computing environments where standard library access is limited. The library supports compile-time configuration to toggle between integer and floating-point coordinate systems. This flexibility allows for precise alignment and rendering adjustments tailored to specific hardware or display requirements. The project is distributed as a single-file header library, facilitating direct integration into existing codebases without external dependencies. ## Tags ### User Interface & Experience - [Layout Engines](https://awesome-repositories.com/f/user-interface-experience/element-positioning/layout-engines.md) — Provides a single-file library for calculating the geometric positions and dimensions of nested rectangular elements using stacking rules. - [C99 UI Layout Libraries](https://awesome-repositories.com/f/user-interface-experience/c-terminal-ui-libraries/c-desktop-ui-libraries/c99-ui-layout-libraries.md) — Provides a portable header-only library for computing interface element coordinates that compiles with standard C99 or C++ compilers. - [Cross-Platform Layout Engines](https://awesome-repositories.com/f/user-interface-experience/cross-platform-layout-engines.md) — Calculates consistent two-dimensional interface geometry across different operating systems and rendering backends using a single portable C codebase. - [Stacking Calculators](https://awesome-repositories.com/f/user-interface-experience/layout-positioning/stacking-calculators.md) — Calculates element positions by recursively applying spatial constraints and relative stacking rules to a hierarchy of rectangular containers. - [Embedded UI Toolkits](https://awesome-repositories.com/f/user-interface-experience/embedded-ui-toolkits.md) — Builds lightweight graphical interfaces for resource-constrained hardware by calculating element positions without heavy external frameworks. - [UI Geometry Calculation Tools](https://awesome-repositories.com/f/user-interface-experience/ui-geometry-calculation-tools.md) — Calculates UI geometry with memory-efficient routines suitable for integration into restricted or specialized computing environments. ### Software Engineering & Architecture - [Layout Calculations](https://awesome-repositories.com/f/software-engineering-architecture/context-aware-validation/layout-calculations.md) — Calculates the geometric positions and dimensions of nested rectangular interface elements by applying stacking rules and spatial constraints.
