Implementation limits

Although WPViewPDF can open almost any PDF file we found, not all of them can be displayed as Adobe Acrobat Reader(tm) would display them. The main reason for this is that our control does not come with its own graphic routines and has to use Windows for the rendering. Transparency is not supported and special, seldom indexed color schemes aren't either.

Fortunately this features are very unlikely used in PDF files created by programming libraries (such as our wPDF or wPDFControl or competing products) so the display should usually be fine as long as PDF data is loaded which was produced from your own application. This was the kind of use we had in mind developing this tool.
