Some options have changed from the official documentation such as pageWidth

After some trial and error I realized the best way to see the options available is to install the binary on your system and run the --help command.

I was having trouble setting pageSize, pageWidth and pageHeight and I realized it was resulting in no output to the stream. After installing the binary it seems those options may not be supported. These are the options the wkhtmltoimage binary showed me:

                                      --disable-smart-width to make it strict.
