The pyViewAsPDF activity is an example of an out-of-the-box solution that you can use to generate a PDF. You can also build a custom activity that matches your business needs and add steps that generate PDF files in the context of that activity. In that scenario, configure the Property-Set-HTML method as described in the following procedure and add a step calling the HTMLToPDF activity.

1. In the navigation pane of Dev Studio, click Records.
2. Expand the Technical category, and then click Activity.
3. Open the pyViewAsPDF activity.
4. Define the HTML content from which you want to generate the PDF:
   1. Expand the Property-Set-HTML method.
   2. In the HTMLStream field, enter the name for the HTML fragment on which you want to base the PDF, and then click the Open icon.
      For example: Enter CompareOffersHTML, and then click the Open icon.
   3. In the New tab, click Create and open.
   4. In the HTML Source field, enter the HTML code that you want to use to generate the PDF.
      Note: If you want to use custom CSS, enable CSS use and upload the style sheet as a text file. For more information, see Creating PDF files by using a compact style sheet.
5. Optional: To enable custom fonts in the PDF output, perform the following actions:
   1. Upload the .ttf file of the font that you want to use as a binary file.
      For more information, see Creating binary file rules.
   2. In the HTML Source field, add the custom font reference by using the @font-face rule.
      For example:

      
          <style>
            @font-face {
              font-family: "Mangal";
              src: url("webwb/mangal.ttf") format("ttf");
            }
          </style>
        

      For more information, see Customizing fonts for your Pega application.

   3. Click Save, and then return to the pyViewAsPDF tab.
6. Define the name for the output PDF file:
   1. Expand the Property-Set method.
   2. In the Param.PDFName row, in the PropertiesValue field, enter the name of the file in double quotation marks.
      For example: Enter "CompareOffers.pdf"
7. Optional: To define custom margins for the PDF file, perform the following actions:
   1. In the step list, click Add a step.
      Note: Ensure that the step precedes the step that contains the call HTMLToPDF activity.
   2. In the new step row, in the Method field, select Property-Set, and then expand the step.
   3. In the PropertiesName field, enter the name of the parameter that you want to adjust.
   4. In the PropertiesValue field, enter the margin size in pixels.
      Note: Margins use the following parameter names:

      Parameter	Default value (px)
      Param.pyMarginLeft	20
      Param.pyMarginTop	10
      Param.pyMarginRight	10
      Param.pyMarginBottom	10

8. Click Save.
