Add alternative source for Ascent/Descent for Type3 fonts - #753
Merged
Conversation
📝 WalkthroughWalkthroughThe change adds Type 3 glyph metric collection. Text bounding-box calculation uses nullable ascent and descent values from ChangesType 3 glyph bounds
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔴 Critical · up to The Type 3 font metric implementation still calls parser methods that are unavailable in the configured dependency, so the project cannot compile and the PR is not merge-ready until the calls or dependency are corrected.
