Xtextscaled

Xtextscaled is a software project that provides scalable text rendering capabilities for editors and viewer components. It introduces a scalable font engine that adapts typography to display density and user preferences while preserving text semantics such as syntax highlighting and line wrapping. The goal is to improve legibility on high-density displays and across zoom levels without requiring manual font adjustments in each application.

Key features include DPI-aware font scaling, configurable minimum and maximum font sizes, smooth interpolation between scales, and an API for integrating with common editor toolkits. It supports theming, font metrics presets, and caching strategies to minimize rendering overhead across frequent font changes.

Architecture comprises a core scaling engine that computes scale factors from DPI and user policy; a font metrics module that caches character dimensions to ensure consistent metrics; an integration layer of plugins for editors and viewers; and a platform adapter layer for Windows, macOS, and Linux. The design emphasizes modularity and minimal intrusion into existing rendering pipelines.

Usage typically involves incorporating xtextscaled as a library or service, initializing it with a configuration that specifies the target DPI or zoom policy, and applying the scaling to rendering calls. It is suitable for IDEs, code viewers, and accessibility tools.

Status and licensing: xtextscaled is presented as an open-source project with ongoing development. Release notes describe incremental improvements, and licensing varies by module but generally follows permissive terms compatible with commercial and academic use.
