Changelog

All notable changes to this project will be documented in this file.

1.0.3 - 2026-07-26

🐛 Bug Fixes

• Image/shape sizing was too small — DocxImage/DocxInlineImage/DocxShapeBlock dimensions are stored in points, but were passed straight through to Flutter's width/height as if already logical pixels; they're now correctly scaled via DocxUnits.pointsToPixels (points × 96/72), matching how the same document renders in Word
• DocxUnits.twipsToPixels divided by 20 (twips → points) and stopped there instead of continuing on to pixels; fixed to twips → points → pixels (twips / 20 * 1.333)
• List bullets stored as Word's Symbol/Wingdings Private-Use-Area glyphs (e.g. U+F0B7) rendered as a "tofu" box on platforms without that exact font installed; these now fall back to a portable Unicode bullet instead
• Dotted/dashed paragraph and table borders were invisible — Flutter's BorderSide only supports solid or none, and they were previously mapped to BorderStyle.none; they're now drawn solid instead of silently disappearing (the closer of the two approximations)

🔧 Improvements

• Bumped docx_creator dependency to 1.3.0

🧪 Tests

• Added test/rendering_accuracy_fixes_test.dart — covers the twips/points → pixel scaling fix (image and shape sizing) and the Private-Use-Area bullet fallback

1.0.2 - 2026-05-16

✨ New Features

• First-line indent (w:firstLine) — positive indentFirstLine now prepends a zero-height WidgetSpan spacer so the first line is indented relative to the paragraph body
• Hanging indent (w:hanging) — negative indentFirstLine values reduce the container left padding to approximate hanging-indent layout
• Line-rule variants — lineRule values 'exact' and 'atLeast' are now handled separately from 'auto': exact clamps the scale to 0.5–10, atLeast floors it at 1.0

🐛 Bug Fixes

• Multi-column vertical merge placeholder — a cell spanning N columns across multiple rows previously produced N separate thin placeholders in continuation rows; it now correctly emits one wide placeholder whose width covers all spanned columns

🧪 Tests

• Added test/parser_test.dart — 5 unit tests covering the cascade rule, table grid matrix, crash immunity, first-line indent spacer, and line-rule variants
• Added test/widget_test.dart — 4 widget tests covering row height ConstrainedBox, multi-column vMerge placeholder child count, search highlight character ranges, and floating image Row layout

🔧 Improvements

• Extracted _resolveLineHeightScale() helper in ParagraphBuilder to centralise line-height logic
• TableBuilder._buildRow() now tracks a parallel skipColSpans array alongside skipCounts to correctly group multi-column vertical merges
• Added .claude/ and graphify-out/ to .gitignore
