Even, I would try it but I'm not being able to build pdfium. I get python errors such

Joaquim,



> I tried to build with your pdfium.lib but got these linking errors.



It seems they are due to your GDAL build also linking against openjp2.lib, and pdfium.lib being linked against its internal copy of openjp2. I don't remember how I tested this. Perhaps this was with a GDAL build without openjp2. Or maybe when building the PDF driver as a plugin the error doesn't show up. I guess you could modify the pdfium build scripts to build against an external openjp2 lib.
