This function was introduced in Quick PDF Library version 10.15.
Creates a canvas of the specified size and returns a Windows device context DC that can be drawn on using Win32 drawing commands. When drawing operations are complete, call the LoadFromCanvasDC function to create a new document from the supplied drawing commands.
The Ex version of the function allows you to pass an existing Device Context handle as a reference when creating the DC.
The return value is defined as either an unsigned integer or a signed integer on different platforms and editions of the library.
