PDF4QT 1.6.0.0 - Image Compression and Workflow Refresh

PDF4QT 1.6.0.0 brings a major image compression and optimization update, especially for PageMaster and assembled output documents. Image compression is now integrated into the assembly/export workflow, backed by new optimizer infrastructure, UI controls, feedback fixes, and tests. This should make PageMaster much more useful for producing smaller output PDFs directly from assembled or reorganized documents.

The release also contains a large PageMaster refresh with improved drag and drop, recent files, crop pages, save/restore functionality, rotation and size indicators, a reworked icon set, and faster output preview rendering. Viewer and Editor workflows were improved with wildcard Advanced Find, Enter-to-search behavior, better outline keyboard selection, startup settings, fullscreen support, side-to-side scrolling, smoother scrolling, text selection, snapping, and expanded annotation controls.

Compatibility and platform behavior were improved as well, including fixes for embedded files, fonts, checkboxes, invisible text, menu colors, highlights, XMP metadata, Windows color management, AppImage packaging, MSIX generation, installer behavior, translations, and newer compiler/Qt warnings. The commit history also includes a new scan-and-edit plugin foundation and color management performance work.
