BuildVu: Gains in Conversion Performance and Viewer Fixes in Latest Update

The July 2025 BuildVu release delivers notable improvements in conversion performance, alongside key bug fixes and viewer enhancements aimed at improving reliability and output consistency.

Announcements

Enhancements

• The conversion engine has been streamlined to create font files more efficiently, a change that notably improves rendering speed in larger files.
• Font decoding has also been made more reliable, addressing issues where incorrect space widths or faulty character maps previously caused layout problems or unreadable text.

Viewer Improvements

• The Complete UI in IDRViewer now behaves more consistently across different browsers. Thumbnails now display correctly in Safari, and the sidebar border no longer appears when the panel is hidden, allowing for a cleaner layout.

Bug Fix Highlights

Many subtle but impactful bugs have been addressed:

• Word spacing inconsistencies caused by inaccurate space width detection have been fixed.
• Firefox users will see improved behavior when working with shape-based text modes, with text selection now fully aligned to the visual appearance.
• Font-related issues, such as problems decoding custom fonts or handling special symbols in font names, are now resolved—ensuring more consistent text rendering and extraction.
• Viewing and conversion of advanced PDF features, like pattern shading and transparency masks, has been made more reliable.
• Improvements in error handling and memory usage reduce the likelihood of conversion failures, even with complex or edge-case documents.
• The handling of embedded font maps has been refined, eliminating overlapping values that led to missing or corrupted text results.

These updates collectively make BuildVu a faster and more robust choice for converting and displaying PDF content online. For a full overview of all the technical changes and enhancements, check the latest release notes.
