Using Aspose.PDF for .NET with Python

This article describes short examples how to create PDF using integration Aspose.PDF for .NET with Python.

Prerequisites

To use Aspose.PDF for .NET in Python please use following requirments.txt:

pip==21.3.1
pycparser==2.21
pythonnet==2.5.2
setuptools==60.1.0

Also, you should put Aspose.PDF.dll in desired folder.

Creating Simple PDF using Python

To work we will need to integrate PythonNet our application and make some setup.

import clr

aspose_pdf = clr.AddReference("D:\\aspose-python-net\\Aspose.PDF.dll")

from System import TimeSpan

from Aspose.Pdf import Document, Color, License, BorderInfo, BorderSide, Rectangle, HorizontalAlignment
from Aspose.Pdf import Table, MarginInfo
from Aspose.Pdf.Text import TextFragment, Position, TextBuilder,FontRepository

Generate simple document

Let’s make a simple PDF with classical text “Hello, world”. For more detailed explanation, please follow to this page

class HelloWorld(object):
    def __init__(self,licence_path):
        self.dataDir = "C:\\Samples\\"
        if licence_path:
            self.licence_path = licence_path
            self.aspose_license = License()
            self.aspose_license.SetLicense(self.licence_path)

    def run_simple(self):

        # Initialize document object
        document = Document()
        # Add page
        page = document.Pages.Add()
        # Add text to new page
        textFragment = TextFragment("Hello,world!")
        textFragment.Position = Position(100, 600)

        textFragment.TextState.FontSize = 12
        textFragment.TextState.Font = FontRepository.FindFont("TimesNewRoman")
        textFragment.TextState.BackgroundColor = Color.Blue
        textFragment.TextState.ForegroundColor = Color.Yellow

        # Create TextBuilder object
        textBuilder = TextBuilder(page)

        # Append the text fragment to the PDF page
        textBuilder.AppendText(textFragment)

        document.Save("HelloWorld_out.pdf")

Creating Complex PDF using Python

Next examples shows how to we can create complex PDF document with images and tables. This example based on the following page.

class HelloWorld(object):
    def __init__(self,licence_path):
        self.dataDir = "C:\\Samples\\"
        if licence_path:
            self.licence_path = licence_path
            self.aspose_license = License()
            self.aspose_license.SetLicense(self.licence_path)

    def run_simple(self):
    # ... skipped ...

    # Make a Complex Document
    def run_complex(self):

        # Initialize document object
        document = Document()
        # Add page
        page = document.Pages.Add()

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

        # Add Header
        header = TextFragment("New ferry routes in Fall 2020")
        header.TextState.Font = FontRepository.FindFont("Arial")
        header.TextState.FontSize = 24
        header.HorizontalAlignment = HorizontalAlignment.Center
        header.Position = 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 = TextFragment(descriptionText)
        description.TextState.Font = FontRepository.FindFont("Times New Roman")
        description.TextState.FontSize = 14
        description.HorizontalAlignment = HorizontalAlignment.Left
        page.Paragraphs.Add(description)


        # Add table
        table = Table()

        table.ColumnWidths = "200"
        table.Border = BorderInfo(BorderSide.Box, 1.0, Color.DarkSlateGray)
        table.DefaultCellBorder = BorderInfo(BorderSide.Box, 0.5, Color.Black)
        table.DefaultCellPadding = MarginInfo(4.5, 4.5, 4.5, 4.5)
        table.Margin.Bottom = 10
        table.DefaultCellTextState.Font =  FontRepository.FindFont("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].BackgroundColor = Color.Gray
            headerRow.Cells[i].DefaultCellTextState.ForegroundColor = Color.WhiteSmoke
            i+=1

        time = TimeSpan(6, 0, 0)
        incTime = TimeSpan(0, 30, 0)

        i=0
        while (i<10):
            dataRow = table.Rows.Add()
            dataRow.Cells.Add(time.ToString("hh\:mm"))
            time=time.Add(incTime)
            dataRow.Cells.Add(time.ToString("hh\:mm"))
            i+=1

        page.Paragraphs.Add(table)

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

How to run generation PDFs in Windows

This snippet shows how to run the examples above on Windows PC. We assumed that class HelloWorld is located in example_get_started.py file. If you run the trial version of Aspose.PDF for .NET, you should pass an empty string as a license_path.

import example_get_started

def main():

    example = example_get_started.HelloWorld("<license_path>")
    example.run_simple()
    example.run_complex()


if __name__ == '__main__':
    main()
