In this demo,
- we take an HTML file that is not the standard 8.5 x 11 size
- convert the HTML file to a PDF and fix the sizing
- then merge it with a PDF that is 8.5 x 11

This allows files to be converted and sized so that they fit with the sizing of the files they are being merged with as a PDF.
Sizing explained in Remarks section of the Resolution Property in the LEADTOOLS Online Documentation

*Please Note* that when you using the project below you will need to include the Leadtools.Pdf.Utilities.dll to the output directory.
Can be copied from here:
C:\LEADTOOLS 20\Bin\Dotnet4\x64
