andimarafioti/faster-qwen3-ttsv1.18.0Sep 8, 2026by abimaelmartell

AI Summary

This release focuses on improving text geometry, specifically handling superscripts and subscripts, and fixing PDF loading issues. It also introduces better metadata for rotated text and embedded fonts while optimizing cross-platform CI and release publishing.

Key Highlights

Superscript/subscript handling and baseline metadata
Positions and regions relative to the visible page box
Rotated-text bounds and rotation metadata
Embedded bold-font metadata recovery
Repair of classic cross-reference tables

Breaking Changes

Positioned items and region APIs now use the visible page box (remove manual CropBox-origin adjustment)
Rust `TextItem` literals must now include `baseline_shift`, `rotation`, and `advance_known`

New Features

Superscript and subscript support
Rotation metadata for text items
Baseline metadata
Bounded object-stream decompression

## Migration

- Positioned items and region APIs now use the visible page box. Remove any manual CropBox-origin adjustment; positioned items use a lower-left origin, while region inputs use a top-left origin.
- Rust `TextItem` literals must add `baseline_shift`, `rotation`, and `advance_known` (`0.0`, `0.0`, and `true` for ordinary upright text).
