Code Review

Lines 14-31 import the UniPDF packages and other required dependencies.

Lines 33-40 authenticate your request with your UNIDOC_LICENSE_API_KEY with the init function.

Lines 42-47 call the RunPDFReport function with an input, which is the path to the PDF you want to create. In this guide, we will save the output to unidoc-report.pdf.

From line 49, we will create the RunPDFreport function in detail.

Lines 50-58 loads the .tff font file into a PDFFont type that can be used in text styling functions. For this example, we will be using the Roboto font (bold and regular).

Lines 60-62 create a new instance of the PDF creator using the .New() method, set the page margins in 4D (left, right, top, bottom) with the setPDFMargin function.

Line 63-122 generates a table of contents for the created PDF with the .AddTOC method. After which, we set a particular page as the front page of the PDF, drawing a header and footer on each created output page using AddHeader and AddFooter functions, respectively. Finally, we save the output to a specific file in the path.

Lines 125-152 style the front page with font, colour and margins. The front page can include paragraphs and headers.

Run the code
