Upgrading?
AI Summary
This release focuses on font rendering precision, specifically improving how subscripts and superscripts are sized and introducing optimizations for ToUnicode CMap repairs to avoid unnecessary processing of fonts where the CMap is already correct.
Key Highlights
- Improved sizing for super/subscript runs based on letters/digits vs. symbols.
- Optimization to skip ToUnicode repairs if the font's CMap is already correct.
- Fixed handling of exponent minus signs in symbol fonts.
Full Release Notes
Changes since 1.25.1: - Size a super- or subscript run by its letters and digits: an exponent whose minus sign a symbol font sets a design size above its digits (as TeX does) keeps its `<sup>` markup; a run of signs alone, or with signs more than a quarter larger than its letters and digits, is still sized by its largest glyph (#603). - Skip a subset font's ToUnicode repairs where the font itself shows the CMap is right: the repair through a `/CIDToGIDMap` for a CMap keyed by code, and the renumbering of a subset that kept its glyph indexes (#605). No API changes. Release preparation: #606. [Full changelog](https://github.com/firecrawl/pdf-inspector/compare/v1.25.1...v1.25.2)
