Creating a complex PDF

The Hello, World example showed simple steps to create a PDF document using Python and Aspose.PDF. In this article, we will take a look at creating a more complex document with Aspose.PDF for Python. As an example, we’ll take a document from a fictitious company that operates passenger ferry services. Our document will contain a image, two text fragments (header and paragraph), and a table.

If we create a document from scratch we need to follow certain steps:

1. Instantiate a Document object. In this step we will create an empty PDF document with some metadata but without pages.
2. Add a Page to the document object. So, now our document will have one page.
3. Add a Image to the Page.
4. Create a TextFragment for header. For the header we will use Arial font with font size 24pt and center alignment.
5. Add header to the page paragraphs.
6. Create a TextFragment for description. For the description we will use Arial font with font size 24pt and center alignment.
7. Add (description) to the page Paragraphs.
8. Create a table, add table properties.
9. Add (table) to the page paragraphs.
10. Save a document “Complex.pdf”.

    from datetime import timedelta
    import aspose.pdf as apdf

    # Initialize document object
    document = apdf.Document()
    # Add page
    page = document.pages.add()

    # Add image
    imageFileName = self.dataDir + "logo.png"
    page.add_image(imageFileName, apdf.Rectangle(20, 730, 120, 830))

    # Add Header
    header = apdf.TextFragment("New ferry routes in Fall 2020")
    header.TextState.Font = apdf.text.FontRepository.find_font("Arial")
    header.TextState.FontSize = 24
    header.HorizontalAlignment = apdf.HorizontalAlignment.CENTER
    header.Position = apdf.Position(130, 720)
    page.Paragraphs.Add(header)

    # Add description
    descriptionText = "Visitors must buy tickets online and tickets are limited to 5,000 per day. \
    Ferry service is operating at half capacity and on a reduced schedule. Expect lineups."
    description = apdf.TextFragment(descriptionText)
    description.TextState.Font = apdf.text.FontRepository.find_font(
        "Times New Roman"
    )
    description.TextState.FontSize = 14
    description.HorizontalAlignment = apdf.HorizontalAlignment.LEFT
    page.Paragraphs.Add(description)

    # Add table
    table = apdf.Table()

    # Add table
    table = apdf.Table()

    table.column_widths = "200"
    table.border = apdf.BorderInfo(
        apdf.BorderSide.BOX, 1.0, apdf.Color.dark_slate_gray
    )
    table.default_cell_border = apdf.BorderInfo(
        apdf.BorderSide.BOX, 0.5, apdf.Color.black
    )
    table.default_cell_padding = apdf.MarginInfo(4.5, 4.5, 4.5, 4.5)
    table.margin.bottom = 10
    table.default_cell_text_state.font = apdf.text.FontRepository.find_font(
        "Helvetica"
    )

    headerRow = table.rows.add()
    headerRow.cells.add("Departs City")
    headerRow.cells.add("Departs Island")

    i = 0
    while i < headerRow.cells.count:
        headerRow.cells[i].background_color = apdf.Color.gray
        headerRow.cells[i].default_cell_text_state.foreground_color = (
            apdf.Color.white_smoke
        )
        i += 1

    time = timedelta(hours=6, minutes=0)
    incTime = timedelta(hours=0, minutes=30)

    i = 0
    while i < 10:
        dataRow = table.rows.add()
        dataRow.cells.add(str(time))
        time = time.__add__(incTime)
        dataRow.cells.add(str(time))
        i += 1

    page.paragraphs.add(table)

    document.save(self.dataDir + "Complex.pdf")
