Hi Brian,
Thank you for the details.
If the MSHTML rendered output PDF files contain one
large bitmap image, generated in machines with IE 9 installed, it can be resolved by updating registry.
How
can we make IE9 to render metafile?
The utility that updates registry is available in the
following location (shipped with version 10.2 and later):
Start->Syncfusion->Essential Studio
x.x.x.xx->Utilities->PDF->IE Legacy Drawing->Enable GDI Rendering
You can get more information regarding this change from
the following MSDN link:
IViewObject
Legacy Drawing
Regarding GeckoWrapper, it is built in debug mode and
both assemblies are required to register the wrapper.
Please try this and let us know if you have any
questions.
Regards
Geetha
