WPViewPDF v6.01.0.0Jul 25, 2026
Features
Integrated WPCubed's original JPEG2000 decoder as well as an equally sophisticated JBIG2 decoder.
Added new font engines for both TTF and PostScript fonts.
The TTF font engine is already used in wPDF V6, where it enables significantly more compact font subsetting than the standard Windows methods.
With these additions, WPViewPDF no longer relies on external DLLs, only the WPViewPDF 6 DLL is required. This makes the whole product safer and programs using it significantly easier to deploy.
