WPViewPDF 3 was created to be very easy to use. So it is possible to plug it into an application, run a few commands and are set for PDF view and print.

The control incorporates very small navigation and zoom controls. They are small but sufficient to select the desired operation.

Of course it is possible to use own controls, not inside the viewer but outside in statusbar or toolbar.

You can switch the rendering engine as well.

By default it is using the "gdi renderer" which provides the best compatibility to many PDF files.

You can switch it off using command(COMPDF_UseGDIPainter, 0) and on using command(COMPDF_UseGDIPainter, 1).

If you switch the GDI renderer off, the redraw is faster, text is usually better aliased but complex clipping is not supported.

Printing will always use the GDI renderer.

New: You can also select a single page view mode and also move the thumbnail window to a different parent window.
